AI Technical Summary
In patients with diabetes, wounds need a dry and refreshing environment during the healing period, but the prior art is difficult to effectively provide a negative pressure environment to promote healing, and the exposed wounds are prone to contamination or touch damage.
A negative pressure suction tube for treating diabetic wounds is designed, including a hose, air outlet, air intake and air pressure control tube. The negative pressure environment at the wound is controlled by adjusting the opening and closing of the vent holes, and combined with a negative pressure air source and a pressure relief tube to maintain the dryness and odor discharge of the wound.
Provides an effective negative pressure environment to keep the wound dry, promote healing, and discharge odors and reduce the risk of contamination.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical appliances and relates to a negative pressure suction tube for treating diabetic wounds. Background Art
[0002] During the wound healing period of diabetic patients, a dry environment is required. Generally, it is recommended to bandage the wound loosely or expose it. However, the air permeability of the wound bandaged loosely with gauze is still not ideal, and the exposed wound is prone to contamination or damage by touch. Content of the Utility Model
[0003] The purpose of the utility model is to provide a negative pressure suction tube for treating diabetic wounds in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to provide a negative pressure environment at the wound to facilitate wound healing.
[0004] The purpose of the utility model can be achieved by the following technical solutions: A negative pressure suction tube for treating diabetic wounds, characterized in that it includes a flexible tube, an air outlet connecting tube located at one end of the flexible tube, and an air inlet connecting tube located at the other end of the flexible tube. A pressure control tube is connected in parallel to the air inlet connecting tube. A plurality of ventilation holes are provided on the wall of the pressure control tube, and the ventilation holes are distributed in the length direction of the pressure control tube. A rubber plug is arranged in the pressure control tube; the air outlet connecting tube is connected to a negative pressure air source.
[0005] Further, a pressure relief tube is connected in parallel to the air outlet connecting tube, and a plug capable of blocking the pressure relief tube is connected to the pressure relief tube.
[0006] During use, the air outlet connecting tube is connected to a negative pressure air source, and the air inlet connecting tube is embedded in the wound dressing bandage, that is, the air inlet connecting tube communicates with the cavity formed between the dressing bandage and the wound. When inserting the air inlet connecting tube, the pressure relief tube can be opened, and the pressure relief tube is closed after the air inlet connecting tube is inserted. The insertion depth of the rubber plug in the pressure control tube can be adjusted according to the situation, so that some ventilation holes are blocked. The more ventilation holes are blocked, the smaller the negative pressure at the wound. The function of the negative pressure is to provide a negative pressure environment at the wound, maintain the dryness of the wound, and at the same time discharge the odor generated during the wound healing process.

[0009] The following are specific embodiments of the utility model in combination with the drawings, and the technical solutions of the utility model will be further described, but the utility model is not limited to these embodiments.
[0010] As Figure 1 shown, the negative pressure suction tube for treating diabetic wounds includes a flexible tube 1, an air outlet connecting tube 2 located at one end of the flexible tube 1, and an air inlet connecting tube 3 located at the other end of the flexible tube 1. A pressure control tube 4 is connected in parallel to the air inlet connecting tube 3. A plurality of ventilation holes 5 are formed in the wall of the pressure control tube 4, and the ventilation holes 5 are distributed in the length direction of the pressure control tube 4. A rubber plug 6 is inserted into the pressure control tube 4; the air outlet connecting tube 2 is connected to a negative pressure air source.
[0011] A pressure relief tube 7 is connected in parallel to the air outlet connecting tube 2, and a plug 8 capable of blocking the pressure relief tube 7 is connected to the pressure relief tube 7.
[0012] During use, the air outlet connecting tube 2 is connected to a negative pressure air source, while the air inlet connecting tube 3 is embedded in the wound dressing band, that is, the air inlet connecting tube 3 communicates with the cavity formed between the dressing band and the wound. When inserting the air inlet connecting tube 3, the pressure relief tube 7 can be opened, and after the air inlet connecting tube 3 is inserted, the pressure relief tube 7 is closed. The insertion depth of the rubber plug 6 in the pressure control tube 4 is adjusted according to the situation, so that some of the ventilation holes 5 are blocked. The more the blocked ventilation holes 5 are, the smaller the negative pressure at the wound is. The role of the negative pressure is to provide a negative pressure environment at the wound, maintain the wound dry, and at the same time discharge the odor generated during the wound healing process.
[0013] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
