Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a wound rinsing device for snake bites. Background Technology

[0002] Chinese utility model patent No. 202121837289.4 discloses a flushing device for treating snake bites. It first flushes the wound with a flushing solution, then uses a negative pressure device to extract the mixture of flushed and drained liquid, achieving a preliminary therapeutic effect. However, the aforementioned patent has the following drawbacks:

[0003] 1. The irrigation fluid is only discharged from one side of the needle to irrigate the wound, while the other three sides of the needle are not rinsed or are not rinsed properly;

[0004] 2. The needle body requires an additional connector to connect to the flushing or negative pressure pipeline, which increases the manufacturing cost. Utility Model Content

[0005] In summary, in order to overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a wound rinsing device after a snake bite.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A snakebite wound rinsing device includes a needle body, a main tube, a rinsing tube, and a negative pressure tube; the needle body is hollow inside and its lower end is inserted into the snakebite wound; one end of the main tube is connected to the upper end of the needle body, and the other end of the main tube is connected to the rinsing tube or the negative pressure tube; the rinsing tube is connected to an infusion pump for conveying rinsing fluid, and the negative pressure tube is connected to a negative pressure pump; a diffusion structure to increase the wound rinsing area is provided on the side wall at the lower end of the needle body.

[0007] The beneficial effect of this invention is that it ensures that the wound can be rinsed from all directions, thus ensuring the rinsing effect.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the diffusion structure includes a spiral groove and a plurality of first flushing holes. The spiral groove is disposed on the outer side wall of the lower end of the needle body, and the first flushing holes are evenly arranged in the spiral groove and penetrate the side wall of the lower end of the needle body.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the wound can be rinsed from all directions.

[0011] Furthermore, the first flushing hole is obliquely downward in the direction from the inner side to the outer side of the lower end of the needle body.

[0012] The beneficial effect of adopting the above-mentioned further solution is that it increases the rinsing area by arranging the rinsing holes relatively horizontally.

[0013] Furthermore, the other end of the main pipe is connected to the flushing pipe or the negative pressure pipe via a three-way switch.

[0014] The advantage of adopting the above-mentioned further solution is that the needle body does not need to be connected to the flushing pipeline or negative pressure pipeline, thus saving manufacturing costs.

[0015] Furthermore, the lower end of the needle body is a rounded tip and is provided with a second flushing hole.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the wound is also rinsed at the position relative to the bottom of the needle. Attached Figure Description

[0018] Figure 2 This is an enlarged view of the lower end of the needle body;

[0019] Figure 3 This is an enlarged cross-sectional view of the lower end of the needle body.

[0020] The attached diagram lists the components represented by each number as follows:

[0021] 1. Needle body, 2. Main tube, 3. Flushing tube, 4. Negative pressure tube, 5. Spiral groove, 6. First flushing hole, 7. Three-way switch, 8. Second flushing hole. Detailed Implementation

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] like Figure 1 As shown, a snakebite wound irrigation device includes a needle body 1, a main pipe 2, an irrigation tube 3, and a negative pressure tube 4. The needle body 1 is hollow and its lower end is inserted into the snakebite wound. One end of the main pipe 2 is connected to the upper end of the needle body 1, and the other end of the main pipe 2 is connected to either the irrigation tube 3 or the negative pressure tube 4 via a three-way switch 7. The irrigation tube 3 is connected to an infusion pump for delivering irrigation fluid, and the negative pressure tube 4 is connected to a negative pressure pump. A diffusion structure is provided on the side wall at the lower end of the needle body 1 to increase the irrigation area of ​​the wound.

[0024] like Figure 2As shown, the diffusion structure includes a spiral groove 5 and several first flushing holes 6. The spiral groove 5 is disposed on the outer side wall of the lower end of the needle body 1, and the first flushing holes 6 are evenly arranged in the spiral groove 5 and penetrate the side wall of the lower end of the needle body 1. The lower end of the needle body 1 has a rounded tip and is provided with a second flushing hole 8. After the flushing fluid is sprayed out from the first flushing holes 6, it flows spirally from top to bottom around the needle body 1 along the spiral groove 5, so that wounds in any direction on the outside of the needle body 1 can be flushed, avoiding the situation where wounds are not flushed properly.

[0025] like Figure 3 As shown, the first flushing hole 6 is obliquely downwards from the inner side to the outer side of the lower end of the needle body 1. The oblique orientation of the first flushing hole 6 allows the flushing fluid to be sprayed obliquely towards the wound, resulting in a larger wound area being flushed compared to a horizontally positioned hole spraying directly out. Furthermore, the oblique downwards orientation of the first flushing hole 6 from the inner side to the outer side of the needle body 1 allows the flushing fluid to flow further along the spiral groove 5 under the influence of liquid pressure and inertia, further increasing the flushing area and improving the flushing effect.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
