Description

Technical Field

[0001] This utility model relates to the field of surgical instrument technology, and in particular to an adjustable pressure hemostatic dressing. Background Technology

[0002] The most commonly used hemostatic dressing is benzalkonium chloride dressing, which contains a cationic surfactant with certain bactericidal effects. It is one of the most frequently used surgical medications in our daily lives, mainly composed of adhesive tape, a medicated absorbent pad, and a protective membrane. In hemostatic dressings, the medicated absorbent pad is in direct contact with the wound, and its main function is to stop bleeding and protect the wound.

[0003] In existing technologies, hemostatic dressings often require the use of bandages to achieve pressure hemostasis, or medical sponges or gauze are inserted into the dressing to achieve pressure. However, it is difficult to control the hemostatic pressure, which increases the patient's suffering. Furthermore, as platelets coagulate, the pressure required for hemostasis gradually decreases. Traditional hemostatic dressings do not have pressure regulation capabilities. Therefore, we propose an adjustable pressure hemostatic dressing to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing an adjustable pressure hemostatic dressing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 An adjustable pressure hemostatic dressing includes a dressing body 1, wherein a pressure-applying component is provided on the dressing body 1, and the pressure-applying component is connected to a pressure-regulating component.

[0023] The pressurizing component includes an airbag body 2 fixedly connected to the dressing body 1. The dressing body 1 has a clearance opening, and the airbag body 2 is located inside the clearance opening. A chitosan dressing block is provided on one side of the airbag body 2. An air inlet pipe 3 is connected to the side of the airbag body 2 away from the chitosan dressing block. A connector assembly matching the pressure regulating component is provided inside the air inlet pipe 3.

[0024] In this design, the airbag body 2 is located in the middle of the dressing body, while the dressing body 1 has adhesive on it, making it easy to stick the hemostatic dressing near the patient's wound. After the dressing body 1 is glued and fixed, the user uses the pressure regulating component to inject air or pressure into the airbag body 2, making the airbag body 2 larger, so that the airbag body 2 can compress the patient's wound to achieve the purpose of pressure hemostasis, and improve the patient's pain feedback and hemostasis effect. The pressure regulating component can be used to adjust the airbag body 2 to minimize the patient's pain while meeting the hemostasis requirements. At the same time, this design also makes the hemostatic dressing adaptable to injuries of different locations and depths, meeting the needs of different types of wounds.

[0025] It should be noted that chitosan dressing blocks are applied directly to the wound. Chitosan has hemostatic and antibacterial properties, promotes tissue regeneration, accelerates wound healing, and also has analgesic effects. It has good biocompatibility and safety, and can be degraded into harmless small molecules in the human body, which are eventually absorbed and excreted by the body.

[0026] Furthermore, the pressure regulating component includes an outer tube 4, a piston 5 is slidably connected inside the outer tube 4, and a push rod 6 is fixedly connected to the piston 5. One end of the outer tube 4 is fixedly connected to a connecting pipe 7, and a ventilation pipe 8 is connected to the connecting pipe 7. A plug 17 is rotatably connected inside the ventilation pipe 8. A through hole 16 is opened on the plug 17 located inside the connecting pipe 7, and a ventilation port 18 is opened on the plug 17. An air inlet 9 matching the ventilation port 18 is opened on the ventilation pipe 8.

[0027] In this design, the outer tube 4, together with the piston 5 and the push rod 6, can inject air or liquid into the airbag body 2 to achieve the purpose of regulating the hemostatic pressure. When using air for pressurization, a large amount of air is required in some cases. After pushing the piston 5 to a position close to the connecting tube 7, the user rotates the plunger 17 so that the through hole 16 is misaligned with the connecting tube 7. At this time, the airbag body 2 and the outer tube 4 are no longer connected and rotated. At this time, the air exchange port 18 is aligned with the air inlet 9, and outside air can enter the outer tube 4 through the air exchange port. At this time, the push rod 6 is pulled to drive the piston 5 to move away from the connecting tube 7. Then, the plunger 17 is rotated back to the initial state so that the through hole 16 is aligned with the connecting tube 7. At this time, the push rod 6 is pushed again to drive the piston 5 to continue injecting air into the airbag body 2.

[0028] Furthermore, the connector assembly includes a connecting sleeve 11 that communicates with the inlet pipe, and a valve core 10 is installed inside the connecting sleeve 11. A push rod 12 for opening the valve core 10 is provided on the connecting pipe 7.

[0029] In this design, the connecting tube 7, in conjunction with the push rod 12, can open the valve core 10, thereby connecting the connecting tube 7 to the airbag body 2. This also allows the pressure regulating component and the connector component to work together. During use, the pressure regulating component is stored by medical personnel, making it difficult for patients or their families to adjust the pressure themselves without the consent of medical personnel, thus improving the safety of this type of hemostatic dressing.

[0030] Furthermore, retaining rings 13 are fixedly connected to both sides of the outer tube 4 and the push rod 6. The retaining rings 13 on both sides of the outer tube 4 can be easily inserted with the middle and index fingers, while the thumb can be inserted into the retaining ring 13 on the push rod 6. This makes it convenient for the user to push and pull the piston 5, making it easy for the user to operate.

[0031] Furthermore, a lever 14 is fixedly connected to the plunger 17. The lever 14 is provided to facilitate the user's rotation of the plunger 17 and to provide a clearer understanding of the plunger 17's status.

[0032] Furthermore, the airbag body 2 is made of transparent material, and an extension edge 15 is provided at the connection between the airbag body 2 and the dressing body 1. The transparent material of the airbag body 2 makes it convenient for medical personnel to observe the hemostatic effect of the wound, while the extension edge 15 improves the fixation effect between the airbag body 2 and the dressing body 1 and increases the adhesion area between the two.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
