Description

Surgical IV infusion set

technical field

The utility model relates to the medical and health field, in particular to an operation intravenous infusion set. the

Background technique

The operating room venous infusion sets used clinically are all assembled with traditional infusion components, but they often cause trouble when faced with some emergencies during the operation. The biggest problem it exists is that it cannot directly administer multi-channel, multi-channel, and instant drug delivery. In the event of an emergency, it will delay the administration time of the surgical patient. If it is in the peripheral intravenous infusion, blood reflux will easily occur in the infusion needle and the infusion catheter. If the time is long, blood coagulation in the infusion needle will occur. If blockage occurs, it needs to be punctured again when infusing again. If it is necessary to replace the leather strap or delete the infusion device during the infusion process, it is easy to cause the infusion liquid to flow out, causing unnecessary waste. the

Contents of the invention

Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a surgical intravenous syringe that provides multiple drug delivery routes, can be effectively combined with surgical equipment, and prevents reflux and other risks.

Technical solution: In order to achieve the above purpose, a surgical venous infusion set of the present invention includes: a sticking needle head, a drip tube connected with the sticking needle head, and the opening at the bottom of the dripping tube is sequentially connected with a current limiting switch through a medical hose. , an air filter, a combination tee, and a positive pressure joint, the other end of which is connected to the infusion needle through an extension tube.

The positive pressure joint is a common component in the medical and health field that can prevent blood backflow and avoid pollution. By installing the end of the infusion hose in the utility model and the access end of the extension tube, the possible problems that may occur can be solved from the entire system. Reflux problem. the

As an improvement of the utility model, the side wall of the drip tube is provided with a first drug injection interface, so as to realize the flushing of the drug on the tube wall and prevent the reaction between the drugs. the

As a further improvement of the utility model, a second drug injection interface is provided between the flow limiting switch and the air filter, so as to realize the comprehensive infusion of various liquids in special cases of the patient during the operation. the

The above-mentioned first drug bolus interface and second drug bolus interface are suitable for syringe administration, but they may be applied to intravenous infusion pumps and other equipment during the operation. At this time, the bolus interface realized by simple puncture cannot meet the demand . In order to solve this problem, the combination tee of the utility model is composed of 1 to 3 revolving tees, and the revolving tees are provided with the first interface, the second interface and the third interface, so The first interface is provided with a plug whose outer diameter matches the inner diameter of the infusion hose and is threaded, and the second interface is provided with a socket matching the plug and its thread, and the plug is provided with a pipe allowing fluid to pass through. The revolving tee of the utility model can be selectively combined according to needs, and configured on the corresponding equipment interface, realizing the creative purpose of multi-channel drug administration. the

Beneficial effects: On the basis of the prior art, the utility model improves the traditional infusion set used in the operating room, and solves the more likely backflow phenomenon during the infusion process, and the air filter ensures The safety of the entire system, and the setting of the drug injection interface and the combination three-way connection realize multi-channel drug administration, effectively combining surgical instruments and equipment to ensure that accidents in the operation can be solved in an orderly manner, providing patients with safety and security. the
