Description

Anti-clogging three-channel surgical irrigation suction tube

Technical field

The utility model relates to an anti-blocking three-channel surgical flushing and suction tube, which belongs to the technical field of medical instruments.

Background technique

Drainage tubes are frequently used consumables in clinical surgery. The common single-lumen drainage tubes currently used clinically have the fundamental defect of poor drainage effect due to passive natural drainage, especially in severe pancreatitis and gastrointestinal anastomotic leakage. , suppurative peritonitis, abscess around the appendix and other situations with large drainage volume and thick drainage, the single-lumen drainage tube can only be used to observe the nature of the drainage, but rarely or cannot achieve any therapeutic purpose For these patients, the drainage is not smooth, and the pollutants containing a large amount of inflammatory mediators and toxin bacteria cannot be removed in time, the consequences are very serious or even fatal. If the single-lumen drainage tube is connected to negative pressure for suction, it is easy to suck the omentum and other tissues in the abdominal cavity into the tube to cause blockage, and eventually lose the drainage effect.

Of course, through searching, we can find several drainage tube design schemes with both continuous flushing and negative pressure suction functions, such as patent No. ZL 201210191445.3 (a dual-chamber drainage tube that can flush and continuous drainage and its application) and ZL 201210365985.9 (medical drainage tube) Invention patents, ZL 200620071975.4 (anti-blocking peritoneal washing drainage tube), ZL 201020633908.3 (anti-blocking single-lumen drainage tube), ZL 94225534.8 (negative pressure drainage tube), ZL 200620010323.X (peritoneal washing drainage tube), ZL201220622714.2 (a multi-lumen drainage device) and ZL 201420139542.2 (a flushable pressure-resistant drainage tube), as well as many other solutions not limited to them, have overcome the shortcomings of ordinary single-lumen drainage tubes to a certain extent, However, there are still one or more disadvantages as described below, including: ① The flushing fluid is mainly used to flush the drainage lumen to prevent pollutants from adhering and accumulating on the tube wall and causing blockage, while the cleaning effect and pollution of the lesion The dilution effect of pollutants is very limited; ②The multi-side hole design at the head end of the drainage tube expands the suction range but also disperses the negative pressure suction, and because the diameter of a single side hole is small, it is not conducive to the passage of relatively thick pollutants. For example, the feces of low intestinal fistula can easily block the side hole, which is especially obvious in the sleeve-type drainage tube that adopts inner tube suction and outer tube flushing; ③ most of them have no air intake channel, only ZL201220622714. cavity drainage device) although there is an air intake channel, the gas does not enter the space outside the tube and cannot form a cavity at the head end of the drainage tube, resulting in no obvious improvement in the situation of easily inhaled omentum or intestinal wall tissue; One channel; ⑤ part of the structure is more complicated and inconvenient to use or the comfort of the human body is low, etc., which limit its large-scale clinical application, so that the above-mentioned unsatisfactory local drainage of patients has not been fundamentally resolved. Change.

Contents of the invention

In order to overcome the poor drainage effect and easy blockage of existing drainage tubes, so that patients with the above conditions can be treated better, the utility model provides a drainage tube with a liquid inlet channel, an air intake channel and a negative pressure channel. The anti-clogging three-channel surgical irrigation and suction tube integrates the functions of liquid flushing, air cavity barrier, airflow promotion and negative pressure suction, which can effectively remove pollutants in the body, and the pipeline is not easy to be blocked.

The utility model originates from the inventor's continuous thinking and exploration in the long-term clinical practice process. The simple three-chamber drainage tube made by ordinary single-chamber rubber drainage tube and infusion set is applied to several patients with intestinal fistula and achieved good results. The technical scheme adopted by the utility model to solve the technical problem is: there are independent flushing pipes and air intake pipes on the main body of the suction pipe, the flushing pipes and air intake pipes are accompanied by the suction pipe, and the head ends of the flushing pipe and the air intake pipe are opened on the suction pipe Outside the head end or flush with the head end of the suction tube, the irrigation liquid and gas can reach the space outside the head of the suction tube through the irrigation tube and the air inlet tube respectively, so that the gas forms a cavity at the head end of the suction tube to prevent the tissue from being sucked into the pipe, while the irrigation The liquid can properly stay in the local area to flush and dilute the lesions and pollutants, so that they will not be sucked away before they can play a role. The suction tube is connected to the negative pressure port on the wall of the ward, or a small medical negative pressure machine is used, and the flushing tube is connected to ordinary intravenous infusion equipment as a flushing device. It can simply inhale outside air, or it can be connected to the oxygen or compressed air interface on the wall of the ward to obtain a higher gas flow rate.

The beneficial effect of the utility model is that flushing the lesion to make it in a clean state is conducive to inflammation subsidence and tissue growth, and pollutants such as exudate, pus, intestinal contents, feces, and necrotic tissue are easier to clean after being diluted with water. After being sucked out, the gas enters the part to form a cavity at the head end of the suction tube, which can prevent the tissue suction tube from being blocked, and form an aerobic environment to inhibit the growth of pathogenic anaerobic bacteria. In addition, the interaction between airflow and water flow further accelerates the suction of pollutants. Compared with the existing drainage tube, the drainage effect is more accurate and reliable, and the patient's recovery time is shortened. The utility model is suitable for postoperative indwelling and drainage of multiple parts such as abdomen, buttocks, neck, back and limbs, especially in closed cavities such as related diseases in the abdominal cavity. The effusion or other pollutants are cleaned up in real time to ensure the smooth progress of the operation.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and corresponding embodiments.

In a preferred embodiment of the present utility model as shown in Figure 1, flushing pipe (2) and air inlet pipe (4) enter in its lumen through suction pipe (1) tube wall respectively, and extend to exceed suction pipe ( 1) The head end, the excess length is preferably 1cm-2cm when used for postoperative indwelling drainage, so that the gas can form a cavity at the head end of the suction tube (1) to prevent the tissue from being sucked into the tube, and the irrigating fluid can also be used locally Appropriate stay to wash and dilute the lesion and pollutants. If it is used to clean up the dirt during the operation, the excess length is preferably 0cm-0.2cm. Too long is not conducive to the suction operation and should not be completely inside the suction tube (1) , so that the gas and flushing fluid are not sucked away before they can do their job. The pipe diameters of the flushing pipe (2) and the air intake pipe (4) are far smaller than the suction pipe (1), preferably 1/4-1/6, otherwise it will cause the suction pipe (1) to be narrow and affect the suction effect. The connections between the flushing pipe (2) and the air inlet pipe (4) and the suction pipe (1) are all airtight. There are several side holes (7) at the head end of the flushing pipe (2) beyond the suction pipe (1), so as to expand the flushing range and strengthen the flushing effect. There is a three-way joint (3) at the end of the flushing pipe (2), when the knob on the three-way joint (3) is When it is in the shape, there are two channels for the flushing fluid to pass through, which is used for thick drainage and poor fluidity; when the knob on the joint is When it is in the shape, there is only one channel for the flushing fluid to pass through, which is used in the case of thin drainage and high fluidity. There are several side holes (7) beyond the suction pipe (1) at the head end of the air intake pipe (4) to expand the cavity range and prevent tissue suction. There is a joint (5) with a one-way valve and an air filter material at the end of the air intake pipe (4), which prevents backflow of flushing fluid and foreign matter and pathogenic microorganisms from being sucked into the abdominal cavity. For parts with more omentum tissue and easy to block the suction tube, you can connect the oxygen or compressed air interface on the wall of the ward to obtain a higher gas flow; for parts with less or no omentum tissue and less chance of suction tube blockage , can only be exposed to the outside air. A negative pressure regulating switch (6) is flexibly connected with the end of the suction tube (1). When used for postoperative indwelling drainage, the irrigation tube (2), air intake tube and suction tube (1) are made of soft rubber or silicone material, and the negative pressure should be adjusted to a lower level in practical applications. It is best to make the suction tube (1) It is in a slightly deflated state, which can further reduce the probability of sucking tissue while ensuring a certain suction force. When used for intraoperative dirt cleaning, the flushing pipe (2), air intake pipe and suction pipe (1) are made of hard plastic or metal materials.

Of course, what needs to be specially explained here is that the accompanying drawings are only simplified schematic diagrams, and their main functions are to reflect the core content such as the design idea and technical principles of the utility model, rather than limiting the structure of the utility model. The final form, especially the details, are not limited to the listed drawings. Under the situation of following the design idea and technical principle of the utility model, many modifications can also be made to the above-mentioned embodiments, for example, the flushing pipe (2) and the air intake pipe ( 4) Do not pass through the tube wall of the suction tube (1) but cling to the outer wall of the suction tube (1) as shown in Figure 2, or set a flushing tube (2) and an air intake tube on the outer wall of the suction tube (1) (4) The running groove, or located inside the tube wall of the suction tube (1), the flushing tube (2) and the intake tube (4) pass through the tube wall before reaching the head end of the suction tube (1) (Figure 3) , etc., all of which do not deviate from the essence of the present utility model, and all should belong to the protection scope of the present utility model, and are not all listed here.
