Description

Technical Field

[0001] The utility model relates to the technical field of medical surgical consumables, in particular to an intraoperative liquid drainage device. Background Art

[0002] Since surgery requires making incisions at local locations on the human body, it is inevitable that damage will be caused to the human skin, blood vessels, organs, etc. Therefore, during the operation, a certain amount of fluid will seep out from the incision site. These exudates are a mixture, containing tissue fluid, blood, pus at the lesion site, etc. In order to prevent the surgical exudates from spreading disorderly around and polluting the surgical environment, the surgical exudates need to be cleaned up in a timely and effective manner to avoid affecting the operation.

[0003] The existing surgical exudate cleaning method is to spread a square towel on the skin after disinfection, then take a square towel and fold it into strips, then repeat the above steps several times to obtain at least three strips of square towels, then surround the at least three strips of square towels around the surgical site to form a non-closed annular area with a small gap to make a waterproof dam to block the surgical exudate, and the small gap is set on the lowest side, then a medical surgical film is attached to the waterproof dam and an open liquid collection bag is fixed on the outside of the small gap. When the surgical exudate overflows, the waterproof dam will block the surgical exudate and guide it to the small gap, and finally flow into the liquid collection bag; however, the operation of the above method is relatively cumbersome, and each operation must be made on-site, which is time-consuming and labor-intensive; in addition, the temporarily made waterproof dam is easy to shift, and the surgical exudate flowing out of the small gap cannot always accurately flow into the liquid collection bag, which will inevitably cause a certain amount of leakage of the surgical exudate, and ultimately pollute the surgical environment, which needs further improvement.

[0019] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0020] like Figures 1 to 3 As shown, an intraoperative liquid drainage device comprises a medical surgical film 1, an annular water retaining dam 2 and a drainage tube 3; the bottom of the annular water retaining dam 2 is a planar structure, and the bottom outer wall of the annular water retaining dam 2 is sealed and attached to the top surface of the medical surgical film 1;

[0021] The annular water retaining dam 2 is made of flexible material;

[0022] The drainage tube 3 is sealed between the annular water retaining dam 2 and the medical operation film 1 , and an opening at one end of the drainage tube 3 is communicated with the inner space of the annular water retaining dam 2 .

[0023] An arc groove 21 is formed between the inner and outer edges of the bottom of the annular water retaining dam 2. Correspondingly, a connecting section 31 cooperating with the arc groove 21 is formed outwardly at one end opening of the drainage pipe 3. The longitudinal cross-section of the connecting section 31 is arched.

[0024] The connecting portion 31 is embedded in the arc groove 21 and the arcuate outer wall of the connecting portion 31 is sealed against the inner wall of the arc groove 21. At the same time, the plane outer wall of the connecting portion 31 is sealed against the top surface of the medical surgical film 1 and is flush with the bottom outer wall of the annular water retaining dam 2. The end opening of the connecting section 31 is interconnected with the inner space of the annular water retaining dam 2.

[0025] The annular water retaining dam 2 is a solid structure or an inflatable hollow structure.

[0026] A double-sided rubber ring 4 is further provided between the annular water retaining dam 2 and the medical surgical film 1 , and the inner and outer contours of the double-sided rubber ring 4 respectively cooperate with the inner and outer contours of the annular water retaining dam 2 .

[0027] The lower outer wall of the double-sided rubber ring 4 is adhered to the top surface of the medical surgical film 1 , and the upper outer wall of the double-sided rubber ring 4 is adhered to the bottom outer wall of the annular dam 2 and the planar outer wall of the connecting portion 31 .

[0028] Directions:

[0029] The medical surgical film 1 is covered on the skin of the patient's surgical area, and then the annular water dam 2 and the connecting part 31 are adhered and fixed to the top surface of the medical surgical film 1 with the help of the double-sided rubber ring 4. At this time, the patient's surgical position is located in the inner space of the annular water dam 2, and then the other end opening of the drainage tube 3 is plugged into the liquid inlet of the drainage bottle; it must be noted that: in the process of fixing the drainage tube 3, it is necessary to change the direction of the annular water dam 2 according to the inclination direction of the skin in the surgical area so that the end opening of the connecting part 31 is located at the lowest side of the annular water dam 2, so that the liquid generated during the operation flows to the side where the end opening of the connecting part 31 on the annular water dam 2 is located.

[0030] Thereafter, the liquid flowing out of the patient during the operation will first flow to the top surface of the medical surgical film 1, but due to the obstruction of the annular water retaining dam 2, the above liquid will not leak to the outside of the annular water retaining dam 2, but will only be confined to the inner space of the annular water retaining dam 2; then, the above liquid will flow in the direction of the lowest position due to the slope of the operating area, and then the above liquid will flow to the side where the end opening of the connecting part 31 on the annular water retaining dam 2 is located, and then gradually flow into the interior of the connecting part 31 through the end opening of the connecting part 31, and finally gather into the drainage bottle through the other end opening of the drainage tube 3, and then the above liquid is safely and reliably transferred to the drainage bottle to effectively prevent the above liquid from polluting the surrounding environment.

[0031] The utility model is simple and convenient to use, and the fixing of the annular water retaining dam 2 can be completed in a short time, thereby simplifying the operation steps to achieve the effect of saving time and labor; at the same time, after the annular water retaining dam 2 is sealed and fixed with the medical surgical film 1, the surgical exudate can be reliably confined in the inner space of the annular water retaining dam 2, and because the annular water retaining dam 2 adopts an integral structure to ensure that the inner space of the annular water retaining dam 2 is always in a closed state, the leakage of the surgical exudate is completely avoided; in addition, the surgical exudate located in the inner space of the annular water retaining dam 2 is automatically and leak-proof transferred to the drainage bottle with the help of the drainage tube 3 to effectively avoid the surgical exudate from polluting the surgical environment.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
