Research On The Rational Use Of Needle-Free Connectors
Needleless connectors are widely used in clinical practice. The purpose of this study was to determine the difference between microorganisms entering six different connectors (three neutral displacements, one negative displacement and two anti-backflow connectors).
Initially connect the needleless connector to the catheter hub to reduce the risk of needle stick injury. Manufacturers have classified needleless connectors based on the type of fluid displacement that occurs when the male luer connector is disconnected. The negative displacement device will return blood to the lumen of the catheter, so a positive pressure technique is needed to avoid obstruction. Neutral displacement devices do not allow blood backflow when disconnected (if they are indeed neutral), and positive displacement devices push blood out of the catheter lumen through the reservoir. All three types of equipment connected to an empty liquid container will allow blood to flow back into the catheter. Therefore, pinless connectors that use anti-backflow technology are now also available. These devices differ from positive displacement needleless connectors in that they contain bidirectional fluid control valves. The valve prevents accidental blood flow back into the intravascular catheter during infusion (for example, when the gravity infusion bag runs out of fluid), connection, disconnection, and changes in the patient's chest pressure.
Activation of the device is usually done through a male Luer connector, which may involve a variety of designs, including opening a cracked septum or depressing the seal in the inlet.
However, subsequent reports indicate that the use of different types of equipment increases the incidence of blood infections. For example, after changing from a needleless joint without a cracked diaphragm to a mechanical positive displacement valve and a negative displacement valve, the ensuing blood infections increased. When using needle-free systems, septum valves may be preferable to some mechanical valves. Do not use positive pressure needleless connectors with mechanical valves until after a comprehensive assessment of risks, benefits, and education about appropriate methods. After this, there are reports that using specific positive displacement connectors can reduce the increased risk of infection. Affecting the updated SHEA / IDSA guidelines, which pointed out that the best design of the needleless connector used to prevent infection is not yet clear. Indeed, it has been suggested that the risk of infection may not be related to the device category (ie negative displacement, positive displacement or neutral displacement), but to the device (ie brand).
The purpose of this study was to determine whether different types of pinless connectors (three neutral displacement connectors, one negative displacement connector, and two anti-reflow connectors) provide similar physical barriers to prevent entry after microbial invasion Challenged by microorganisms under simulated controlled clinical conditions. The main outcome indicator is the number of Staphylococcus aureus through the connector. This is determined by collecting the liquid flowing through the device. In addition, with the passage of time and two different purification schemes, the risk of microorganisms entering the connector was evaluated.

Vaginal Speculum Mould-Why Use A Vaginal Speculum?
helps prevent the vaginal walls from sticking to each other and close the scar during healing. As the healing progresses, the radiation causes fibrosis (scarring process) in the vaginal wall. Using a dilator every week or having a total of 2-3 sexual intercourses can help keep the vagina as deep and wide as possible. Repeatedly, studies have shown that most women do not follow the usual recommendations, use dilators or have intercourse 3 times a week, even within a few months after radiotherapy, or even within a few months after radiotherapy, although scars remain It continues, but for many years. occur.
After vaginal reconstruction: If a woman undergoes surgery to reconstruct the vagina due to birth defects, future health problems, or after cancer treatment, you can tailor a Vaginal Speculum for her during sleep and within a few hours of sleep Wear it that day. The dilator helps the new vagina to be as deep and wide as possible during the healing process. If a skin graft is used to make the vagina, it is most likely to use a dilator. The vagina created by the intestine or skin and muscle flaps may not need them.
To maintain long-term vaginal size after menopause or cancer treatment:
Vaginal Speculums can help women maintain enough vaginal size and stretch for painless intercourse or pelvic examination after menopause. Dilators are also helpful during times when patients need anti-estrogen therapy for breast cancer. In addition, Vaginal Speculums are used to prevent scar formation during donor versus host syndrome after donor stem cell or bone marrow transplantation.
Create a vagina for young women who have no babies: some women have no babies. Instead, they have a small "dimple", which is a dead end. When they reach adulthood, they can choose surgery to create the vagina or expand it. They pressed the dilator into the vaginal opening for about half an hour, twice a day. Within a few weeks, they can deepen their openness to have sex with a male partner. However, they must continue to use dilators or regular sexual activity to maintain the vaginal tube. If their condition involves abnormally low hormone levels, they also use estrogen ointment to improve the elasticity of the vaginal area.
To treat the fear of vaginal penetration: some women are strongly worried about something entering the vagina. This problem is called vaginal cramps or pelvic floor pain. Sex therapists used to think that women with vaginosis would clench vaginal muscles so they could not penetrate. Recently, it has been recognized that this problem is a phobia caused when a partner tries to insert a finger or penis into the vaginal entrance. Muscle tension may coexist with fear, but not always. Women can usually overcome vaginal spasms by practicing muscle relaxation while using a set of Vaginal Speculums of different sizes. The key factor is that women can control what goes into the vagina.

Three Way Stopcock Action Of Medical Self-Supporting Body
A Three Way Stopcock with a medical self-supporting body has at least two ways controlled by a one-way flow control element and a third way that is always open.
The new invention relates to a Three Way Stopcock with a self-supporting body for medical use. Pre-assembled single-use devices, called "devices", have long been used in the medical field, and generally allow the administration of drugs and the like to patients to ensure the sterility of the assembly.
These devices basically consist of a plurality of interconnected tubes having an appropriately standardized coupling at their ends, the coupler having a convex or concave cone (Luer cone), and Connect the vial to a needle inserted into the patient's vein or arterial circuit. Then, if necessary, a valve, a throttling device, an insertion point for the syringe and other components are placed along the tube so that the intended treatment can be performed with maximum safety and efficiency.
Functionally, these devices operate satisfactorily overall; however, operators in the field, in fact doctors and nurses, increasingly demand ease of operation, which allows tube and bottle execution to be performed with maximum speed and minimal awkwardness. Or several operations of tube and needle connected to each other.
In this case, some devices have pipes and connections, and due to the nature of the treatment to be performed, they must have at least three useful lines, all of which must be controlled by means of valves, which are suitable for example to prevent The return of the patient may allow multiple drugs to be mixed and dosed; especially in these cases, the operator needs to be able to provide multiple connections to the device faster and easier, and also to ensure that accidental and dangerous switching of connections does not occur.

Technical Innovation Of Three Way Stopcock
Three Way Stopcock useful in the medical field, where an arm or channel is attached to an intravenous catheter or needle, while the other arm is used to administer intravenous fluids.
The goal is to achieve a three-way stopcock with excellent functionality, thereby achieving improvements in the way the arm or channel is associated with the intravenous bottle or container containing the therapeutic product. Another purpose is to better adapt the plug valve to the needs of the patient.
Three-way stopcocks are widely used in the medical and health fields for administering various products such as serum, nutrients and drugs through intravenous catheters. Patients with dementia and other coexisting pathological and cardiovascular problems are those who most need this stopcock to infuse one or more intravenous drugs simultaneously.
The utility model patent describes a three-way stopcock, which is characterized in that two secondary arms or paths emerge from the core of the atomic nucleus forming an orthogonal elbow along its trajectory.
Because the drugs and nutrients administered to a patient intravenously are solutions consisting essentially of liquid solid microelements, these microelements may deposit on the walls of the arms or channels, thereby impairing the full flow of fluid. Therefore, the presence of orthogonal elbows in the plug valves described in the aforementioned patents makes it difficult to eliminate the blocking of arms or channels. This problem has a negative impact on intravenous treatment, as drugs delivered to patients need to be managed within a specific time period.
Another problem raised by previously described plug valves with orthogonal elbows is reduced flexibility. For example, in situations where a medical staff needs to manipulate an arm or channel, such as changing an intravenous container or bottle containing a venous treatment product or disconnecting an auxiliary line from a main catheter, the main arm connection may be damaged. Intravenous catheters, which affect the supply of these products. Because the primary arm is directly connected to a catheter previously inserted into the patient's vein, any manipulation of the secondary arm can severely affect the venous connection, creating a pressure leak. Therefore, in view of this problem, it is desirable to have a three-way plug valve in which the jib is flexible.
In view of the previously outlined occlusion issues in secondary arms or channels and their reduced flexibility, improved three-way plug valves have been developed to address and meet these issues. In addition, due to this newly designed construction, the plug valve of the present invention provides greater flexibility. As a result, health personnel can operate the jib more easily and safely. If it acts on the auxiliary arm or route, it will not affect the main arm or channel. In this way, the secondary arm or path can be moved with greater freedom, so the intravenous treatment will not cause damage to the patient. In this way, the present invention solves problems such as pressure leakage.
The three-way sanitary plug valve developed by the present invention solves the aforementioned blocking problem on the basis of eliminating the orthogonal trajectory of the jib and replacing it with a curved trajectory.
According to a first object of the present invention, a three-way stopcock is a three-way stopcock composed of a cylindrical core or a body having a stopper or plug processed by a handle inside, the core converging on a main swing arm. The catheter is inserted into the patient's vein and there are two auxiliary arms or channels that receive other catheters that provide drugs or therapeutic fluids. The two auxiliary arms are diametrically opposed and are out of phase with respect to the main arm. Cross, because these auxiliary arms are characterized by an initial bend, are flexible and have a high elastic index, and then continue to remain clearly parallel to each other in their final part.
Therefore, like the intravenous catheter, the two connecting catheters of the plug valve's forearm also extend significantly parallel and are oriented towards the bedside of the patient undergoing intravenous treatment. This is the most advantageous direction, as bottles or containers containing medicines or nutrients are usually located on the patient's head.
The curvature and flexibility of the initial portion of the secondary arm prevents the secondary arm from becoming blocked, so intravenous infusion therapy is more effective because the volume of drugs and nutrients to be injected takes place within the required time. In addition, the initial section has a high elasticity index, so the ability to return to its initial position is greater, allowing the secondary arm to be used with greater safety.
Accordingly, the present invention is implemented, and the stopper or stopper located in the core or body cavity has an apparently “V” -shaped internal structure to allow the treatment fluid to pass through at the same time, while allowing fluid to flow. One of the auxiliary arms shuts off the flow to the other, and even shuts off the flow to the two auxiliary arms when needed.
Therefore, another implementation of the present invention is that the main arm and the jib will be made of medical grade polymer or plastic.
