Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a wound washing device. Background Art

[0002] As we all know, VSD technology was first invented by Fleischman et al. of ULM University in Germany in 1992. In recent years, domestic scholars have widely applied it to the drainage of various wounds. This technology is widely used in orthopedics and general surgery. The mechanism of VSD is: (1) Sealing maintains the high negative pressure as the drainage power, and at the same time isolates the drainage area from the outside world, effectively preventing contamination and cross infection; (2) High negative pressure sealing can continuously drain the exudate, necrotic tissue, bacteria, toxins, etc. in the wound, so that the drainage area can achieve "zero accumulation" and the wound can quickly obtain a clean environment; (3) Increase the blood supply to the wound, improve the microcirculation of the wound, and promote the growth of granulation tissue. VSD can significantly enhance the proliferation and microvascular density of endothelial cells and fibroblasts in the superficial dermis of the wound tissue; (4) Regulate the activity of gelatinase in the wound, improve the microcirculation in the wound base, inhibit the degradation of collagen and gelatin, and promote the healing of the wound; (5) Reduce periwound edema and reduce vascular permeability. VSD can significantly promote wound healing by enhancing the secretion of substance P and calcitonin-related gene peptide from peripheral nerve endings and affecting the expression of endogenous epidermal growth factor.

[0003] At present, a Chinese patent with announcement number CN108211025B discloses a wound negative pressure irrigation and drainage device, which includes an irrigation tube, a sponge and a suction tube. One end of the irrigation tube is connected to physiological saline through the drainage device, and a liquid outlet hole is opened on the tube wall of the other end of the irrigation tube and the end is located on the lower end surface of the sponge. At the same time, the end is covered on the wound through the sponge. The area of ​​the sponge can fill the incision around the wound. A layer of film A is covered on the upper end surface of the sponge. The area of ​​film A is larger than the area of ​​the sponge. The surrounding areas are used to bond to the patient's skin. The part of film A located at the sponge has a long axis opening. One end of the suction tube is located in the long axis opening and a liquid suction hole is opened on the tube wall of the end. The other end of the suction tube is connected to the suction device. A layer of film B is covered on the top of the suction tube. Film B is used to seal the wound, and the area of ​​film B is larger than the area of ​​the sponge.

[0004] Although the above-mentioned wound surface negative pressure irrigation and drainage device is easy to operate, can reduce the scope of surgical site infection, shorten hospitalization time, and improve the success rate of wound treatment, the above-mentioned wound surface negative pressure irrigation and drainage device still has the following defects in actual use:

[0005] The liquid outlet hole on the flushing tube and the liquid suction hole on the suction tube are arranged to overlap with each other, so that part of the flushing liquid just flushed in is sucked away by the liquid suction hole, which affects the flushing effect. In addition, the design of the flushing tube has defects that make the flushing effect poor.

[0006] Therefore, a wound surface flushing device is proposed. Utility Model Content

[0040] Among them, one end of the suction tube 3 is connected to the negative pressure suction device, and the other end of the suction tube 3 is fixed and connected to a suction head 301, which is attached to the upper part of the PU sponge block 1 and is arranged close to the other end of the PU sponge block 1 in the length direction.

[0041] Among them, the plurality of liquid outlet holes 202 are all arranged toward the suction head 301 .

[0042] The wound flushing device using the above technical solution is mainly composed of a PU sponge block 1, a flushing tube 2 and a suction tube 3, wherein a cylindrical hollow flushing head 201 is fixed and connected to one end of the flushing tube 2, and a plurality of liquid outlet holes 202 are evenly opened on the cylindrical hollow flushing head 201 along its length direction, so that the flushing tube 2 is T-shaped as a whole, so that the distribution area of ​​the plurality of liquid outlet holes 202 can cover the PU sponge block 1 as much as possible, and the flushing area can be expanded, thereby effectively improving the flushing effect on the wound surface. At the same time, the plurality of liquid outlet holes 202 are arranged with a spacing from the suction head 301 at one end of the suction tube 3, which can prevent the flushing liquid that has just been flushed in through the liquid outlet holes 202 from being partially sucked away by the suction head 301 and affecting the flushing effect.

[0043] Specifically, in order to make the PU sponge block 1 stably adhered to the wound surface and prevent the flushing liquid from flowing everywhere, a film 4 is also provided. In order to facilitate the observation of the flushing status, the film 4 is a transparent plastic film. In order to completely cover the PU sponge block 1, the area of ​​the film 4 is larger than the area of ​​the PU sponge block 1, and the film 4 is covered on the upper part of the PU sponge block 1, and the flushing tube 2 and the suction tube 3 are both penetrated through the film 4. In order to prevent leakage, the penetration points of the flushing tube 2 and the suction tube 3 and the film 4 are all sealed.

[0044] Specifically, in this embodiment, in order to ensure the performance of the suction head 301 in sucking liquid, the suction head 301 is configured as a trumpet-shaped hollow shell structure, which can be made of flexible plastic or silicone, and a liquid suction hole is provided at one end of the suction head 301 away from the suction tube 3.

[0045] Specifically, in this embodiment, in order to meet the usage requirements of different clinical scenarios, the flushing tube 2 and the suction tube 3 are both cuttable plastic hoses, so that the flushing tube 2 and the suction tube 3 can be cut and used according to the usage requirements of different clinical scenarios.

[0046] Specifically, in this embodiment, in order to effectively prevent the flushing liquid just flushed in through the liquid outlet 202 from being partially sucked away by the suction head 301 and affecting the flushing effect, the distance between the suction head 301 and the liquid outlet 202 is not less than 1 cm.

[0047] Specifically, in this embodiment, in order to meet the needs of clinical use, the PU sponge block 1 is arranged in a rectangular shape, and the four corners of the PU sponge block 1 are all rounded structures.

[0048] Specifically, in this embodiment, in order to allow the distribution area of ​​the plurality of liquid outlet holes 202 to cover the PU sponge block 1 as much as possible to expand the flushing area, the length of the cylindrical hollow flushing head 201 is equal to the width of the PU sponge block 1 .

[0049] It is worth mentioning that the flusher and the negative pressure suction device in this embodiment are both existing technologies.

Of course, its specific structure and model are not limited here.

[0050] In summary, the wound flushing device provided in this embodiment has the following advantages:

[0051] The wound flushing device has a cylindrical hollow flushing head 201 fixed and connected to one end of the flushing tube 2, and a plurality of liquid outlet holes 202 are evenly opened on the cylindrical hollow flushing head 201 along its length direction, so that the flushing tube 2 is T-shaped as a whole, so that the distribution area of ​​the plurality of liquid outlet holes 202 can cover the PU sponge block 1 as much as possible, and the flushing area can be expanded, thereby effectively improving the flushing effect on the wound surface. At the same time, the plurality of liquid outlet holes 202 are arranged with a spacing from the suction head 301 at one end of the suction tube 3, which can prevent the flushing liquid that has just been flushed in through the liquid outlet holes 202 from being partially sucked away by the suction head 301 and affecting the flushing effect.

[0052] When in use, the PU sponge block 1 is attached to the wound surface, and then the film 4 is attached to the skin around the patient's wound surface. The PU sponge block 1 is firmly attached to the wound surface using the film 4. Then one end of the flushing tube 2 is connected to the flusher, and one end of the suction tube 3 is connected to the negative pressure aspirator. The flusher can be used to flush medicine or flushing liquid into the PU sponge block 1. The medicine or flushing liquid contacts the wound surface through the PU sponge block 1 to flush the wound surface. Then the medicine or flushing liquid flows to the area where the suction head 301 is located and is sucked away by the negative pressure aspirator. The whole process can prevent the medicine or flushing liquid from flowing everywhere, and at the same time prevent the wound surface from being contaminated, and the flushing effect is better.

[0053] The wound flushing device can be used on infected wounds to flush out drugs and promote wound healing. Due to the large number of liquid outlet holes 202, the cylindrical hollow flushing head 201 can be prevented from being blocked. It is particularly suitable for treating refractory wounds, expanding the indications and enhancing the efficacy.

[0054] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
