Abstract
Description
Technical Field
[0001] The utility model relates to a medical device, in particular to a disposable multi-functional medical arthroscope infusion set. Background Art
[0002] In some surgical operations, such as arthroscopic knee surgery, arthroscopic shoulder surgery, foraminal arthroscopic surgery, etc., since the operation points of these surgeries are all performed in water, doctors need to use normal saline to wash away blood stains to see the field of view clearly during the operation. Existing normal saline comes in 500 ml and 3000 ml. The amount of 500 ml is not enough to support the end of the operation, and often the normal saline runs out, resulting in an unclear surgical field of view and delaying the surgical process. Using 3000 ml of large-capacity flushing fluid will cause waste because one bag is not enough for one patient, and the second bag cannot be used up, and the unused fluid cannot be used by the next patient either. This is the drawback of large-capacity flushing fluid. Moreover, as the amount of the large-capacity flushing fluid decreases towards the end, the pressure becomes smaller, resulting in a slower flow rate. And if pressurization is required during the operation, this large-capacity fluid cannot achieve it because there is no large enough pressure booster. Due to insufficient water pressure, the surgical field of view is unclear, and manual squeezing is required, which is not conducive to the circulating nurse observing the patient's condition changes. In this process, human support is needed, and the work efficiency is difficult to improve, wasting working time.
[0003] If there is a multi-functional medical arthroscope infusion set, it can not only save working time, improve efficiency, reduce waste, but also control the water pressure well. However, there is currently no such arthroscope infusion set, and it is necessary to conduct research and development. Summary of the Utility Model
[0004] Therefore, the utility model provides a disposable multi-functional medical arthroscope infusion set, which can provide continuous cleaning and infusion for the arthroscopic surgery process, will not cause excessive waste of cleaning fluid, and can also ensure relatively stable infusion pressure, thereby overcoming the deficiencies of the prior art.
[0005] The disposable multi-functional medical arthroscope infusion set provided by the utility model has a large liquid storage bladder, a small liquid storage bladder, a balloon pump and a pipeline valve. It is characterized in that the bottoms of the large liquid storage bladder and the small liquid storage bladder are respectively provided with liquid outlet pipes connected to the infusion pipe, and the infusion pipe is connected to the arthroscope inlet pipe. Valves are provided on the liquid outlet pipes of the large liquid storage bladder and the small liquid storage bladder to respectively control the opening and closing of their respective liquid outlet pipes. There is also a pressurization pipe at the bottom of the small liquid storage bladder, and a balloon pump is connected to the pressurization pipe through a one-way air inlet valve to add gas and increase pressure to the bladder. The tops of the large liquid storage bladder and the small liquid storage bladder are respectively provided with liquid inlet pipes and exhaust pipes, and valves are provided on the liquid inlet pipes and the exhaust pipes. There is a heparin cap on the liquid inlet pipe of the small liquid storage bladder for rapid liquid addition.
[0006] The upper ends of the liquid inlet pipes at the tops of the large and small liquid storage sacs are Y-shaped liquid receiving ends for rapid liquid inlet, and the exhaust pipes are replaced by heparin cap needles.
[0007] Pressure gauges are installed at the bottoms of the large and small liquid storage sacs to display the real-time pressure changes inside the sacs, guide pressurization, and ensure the stability of the liquid outlet pressure of the infusion tube.
[0008] The exhaust pipes at the tops of the large and small liquid storage sacs can be flexible hoses, and their valves can be replaced by stretching, folding, or pipe clamps to open and close.
[0009] There are pipe connectors at the ends of the infusion tube for quick connection and separation from the liquid inlet tube of the arthroscope.
[0010] An infusion valve is also provided on the infusion tube to control the opening and closing of the infusion tube.
[0011] The capacity of the large liquid storage sac is 3500 - 5500 ml, and the capacity of the small liquid storage sac is 600 - 650 ml to accommodate different specifications of normal saline flushing solutions.
[0012] There are also pressurizing pipes and air bags at the bottoms of the large liquid storage sacs for emergencies.
[0013] The large and small liquid storage sacs and the connecting pipes are made of medical plastic or latex materials, and are sterilized and packaged with plastic films for single use.
[0014] The working principle of the present utility model is as follows:
[0015] During use, open the package, transfer all the large bag of normal saline flushing solution (usually a 3000 ml bag) through the liquid inlet tube into the large liquid storage sac, and close the valves of the exhaust pipe and the liquid inlet tube. Hang it on the infusion stand with accessories such as a net bag. Connect it to the flushing tube of the arthroscope through the pipe connector, and open the valves of the large sac and the exhaust pipe to infuse and flush the arthroscope.
[0016] When the normal saline in the large liquid storage sac drops close to the bottom, the pressure will decrease, and the flow rate of the arthroscope flushing solution will slow down. At this time, the one-way air inlet valve can be opened through its air bag for manual pressurization to try to use up all the normal saline.
[0017] When the normal saline in the large liquid storage sac is almost used up and the arthroscopic surgery has not ended, open the liquid inlet valve of the small liquid storage sac to fill the small bag of normal saline (usually a 500 ml bag) through the liquid inlet tube. Immediately close the valve of the large sac of the large liquid storage sac, open the valve of the small sac to continue infusing the arthroscope. If it has not ended yet, fill the small liquid storage sac with normal saline again until the arthroscopic surgery ends. Normal saline can also be quickly injected from the heparin cap with a large syringe.
[0018] At the end of the operation, even if there is some remaining normal saline in the small liquid storage bag, it will not cause too much waste. In this way, the waste caused by the unused large bag of normal saline can be avoided.
[0019] When the normal saline in the small liquid storage bag drops to the bottom, by pressing the air balloon, due to the small volume, only a small amount of air needs to be pumped in to reach the required pressure, so it is more labor-saving and time-saving.
[0020] The utility model has a simple structure, is easy to operate, convenient and fast, can provide continuous cleaning and infusion during the percutaneous endoscopic surgery, will not cause excessive waste of cleaning fluid, can also ensure a relatively stable infusion pressure, is for single use, avoids the possibility of cross-infection, and is hygienic and safe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0025] The present utility model will be further described below with reference to the accompanying drawings.
[0026] As Figure 1 shown, the large liquid storage bag 17, the small liquid storage bag 5, and their liquid inlet pipes 1, exhaust pipes 4, pressure pipes 6, large liquid storage bag liquid outlet pipes 16, small liquid storage bag liquid outlet pipes 10, and infusion pipes 12, etc. are all made of common materials such as medical plastics and latex. The capacities of the large and small liquid storage bags are set at 3500 - 5500 ml and 600 - 650 ml respectively, so as to leave a certain space for normal saline of 3000 ml and 500 ml specifications. The pressure pipe 20 is connected to the air balloon 9 and the supporting one-way air inlet valve 8.
[0027] A pressure gauge 7 is installed on the piezometer tube 6, which can display the pressure change in the liquid storage bag in real time. When the pressure is lower than the normal value, manual rapid pressurization can be carried out through the air bag 9 to maintain the normal requirement.
[0028] The exhaust pipe 4 can be a flexible hose, and the exhaust valve 3 on the pipe can be replaced by stretching or folding the hose or using a pipe clamp to open or close it.
[0029] Such as Figure 2 As shown, for rapid liquid filling, a Y-shaped liquid receiving end 21 is connected to the liquid inlet pipe, so that normal saline can be quickly introduced into the large and small liquid storage bags through the double pipes. A heparin cap 19 is installed on the liquid inlet pipe of the small liquid storage bag, and the function of the exhaust pipe is replaced by inserting an injection needle into the heparin cap.
[0030] Figure 1-2 The heparin cap 19 in [[ ]] can also be used to quickly inject normal saline.
[0031] The pressurization pipe, air bag and heparin cap of the large liquid storage bag are preparatory settings. Except when the normal saline in the bag is used up, they are generally not used usually. Only when an accident occurs and the small liquid storage bag fails, they are used. Because it is time-consuming and laborious to supplement normal saline and pressurize through the large liquid storage bag. Only the small liquid storage bag can achieve rapid liquid supplement and pressurization.
[0032] The remaining components and labels not mentioned are as described above. The above various valves can be abbreviated as valves.
