Description

Drainage device suitable for drainage of subcutaneous fluid

technical field

The utility model relates to medical auxiliary equipment, in particular to a special drainage device suitable for subcutaneous fluid drainage.

Background technique

After the surgical operation is completed, the surgical incision needs to be sutured. During the recovery process of the patient, the subcutaneous fat layer at the incision of some patients will liquefy, resulting in fluid accumulation in the fat layer, which seriously affects the healing of the incision. Currently, there is no drainage device specially used for draining subcutaneous fluid to the outside of the body. Currently, the gauze soaked with medicine is generally stuffed into the subcutaneous fat layer, and the fluid is completely sucked out through the gauze. The above operation method has the following disadvantages: firstly, the gauze packing process is cumbersome, and sharp instruments such as tweezers or surgical forceps are needed during the packing process, which is easy to pierce the muscle layer or peritoneum at the incision, or even damage internal organs; secondly, the gauze is replaced The time is long and troublesome, and the incision is very susceptible to infection; moreover, the subcutaneous fluid is often enriched in the deepest part of the incision, and it is difficult to completely suck out the fluid only with gauze, and the growth rate of granulation tissue is fast, and the granulation tissue is easy to grow into the gauze. It is difficult to take out the gauze and increases the pain of the patient.

Contents of the invention

The purpose of the utility model is to provide a special drainage device suitable for drainage of subcutaneous effusion. The drainage device has fast drainage speed and good effect, and is helpful for the healing of patients' incisions.

In order to achieve the above object, the utility model takes the following technical solutions:

The drainage device suitable for the drainage of subcutaneous effusion described in the utility model comprises a drainage tube with drainage holes evenly distributed on the tube wall and a guiding tube connected to the drainage tube. Coated with an antibiotic layer, the outer wall of the guide tube is engraved with a length scale line along its length direction, and a connecting tube is arranged at the liquid outlet end of the guide tube, and the connection between the guide tube and the connecting tube The included angle α<90°, the liquid outlet end of the connecting pipe is connected with a flexible suction bottle with a volume scale line, and the volume of the flexible suction bottle is 3-15mL.

The included angle β between the drainage tube and the guide tube is ≤90°.

The diameter of the drainage tube is 0.2-1 cm, the length of the antibiotic layer on the inner and outer walls of the drainage tube is 5-20 cm, and the length of the guiding tube is 3-10 cm.

The utility model has the advantages of simple structure and convenient use. The drainage holes on the drainage tube are densely opened to prevent blockage, and the antibiotic layer prevents infection of patients; If it is too deep, the newly grown muscle will be punctured, which is safe; the angle between the guide tube and the connecting tube is an acute angle to prevent sucking back.

detailed description

As shown in Figure 1 and Figure 2, the drainage device suitable for the drainage of subcutaneous effusion described in the utility model includes a drainage tube 2 with drainage holes 1 evenly distributed on the tube wall and a drainage tube connected to the drainage tube 2. The guide tube 3, the included angle β between the drain tube 2 and the guide tube 3 is 90°, which is convenient for placing the drain tube 2, and at the same time helps guide the guide tube 3 out of the skin. The diameter of the drain tube 2 is 0.5cm (Of course, other values within the range of 0.2 to 1 cm can also be used during actual manufacturing.) The inner and outer walls of the drainage tube 2 are coated with an antibiotic layer with a length of 10 cm, which reduces the chance of infection of the incision of the patient and reduces the number of dressing changes; The length of the guide tube 3 is 5 cm, and the length scale line 4 is engraved on the guide tube 3 along its length direction. The zero scale of the length scale line 4 starts from the end where the guide tube 3 is connected with the drain tube 2, which is convenient for observing the drainage The insertion depth of the tube 2 prevents the muscle or peritoneum from being pierced through the incision too deeply. The included angle α between the tubes 5 is 60° (of course, the included angle α between the central axis of the guide tube 3 and the central axis of the connecting tube 5 can also be any other acute angle value), to prevent sucking back, the connecting tube 5 A flexible suction bottle 7 with a volume scale line 6 is connected to the liquid outlet end, and the volume of the flexible suction bottle 7 is 10 mL.

During actual manufacture, both the drainage tube 2 and the guide tube 3 are made of plastic to prevent granulation tissue from growing into the drainage tube 2; the flexible suction bottle 7 is made of soft plastic and can be squeezed; during actual manufacture, the device can be made into different specifications, To meet the needs of different patients with different fat liquefaction conditions.

When in use, choose the appropriate size device according to the patient's fatness and fat liquefaction, then sterilize the patient's incision, then stretch the surgical incision, place the drainage tube 2 horizontally in the incision, and the drainage tube 3 outwards Extend out of the body, then fix the guide tube 3, and make the bottle body of the flexible suction bottle 7 lower than the height of the liquid outlet of the guide tube 3, squeeze the flexible suction bottle 7 by hand to discharge the air, and then release the flexible suction bottle 7. The effusion in the fat layer enters the flexible suction bottle 7 through the drainage hole 1, the drainage tube 2, the guide tube 3 and the connecting tube 5 in order to improve the drainage efficiency; when the effusion in the incision disappears, pull out the device Just go out. This device avoids the situation where sharp instruments are stuck into the incision, ensures the safety of the incision, reduces the frequency of dressing changes, and effectively reduces the chance of the patient's incision being infected.
