Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a negative pressure drainage component that is easy to fix and replace. Background Technology

[0002] One of the long-standing challenges for patients after microtia surgery is the fixation and replacement of the negative pressure drainage system. Because patients with microtia need to rely on negative pressure drainage to prevent skin flap necrosis after the first and second stage surgeries, the continuous negative pressure suction device restricts the patient's ability to get out of bed after surgery due to the characteristics of the tubing connection. Therefore, a negative pressure drainage component that can be fixed to the body is needed.

[0003] Utility model patent CN203154534U discloses a negative pressure drainage tube, which has multiple drainage holes at the front end of the tube body to facilitate the outflow of exudate and reduce the occurrence of blockage. The fixing clip with four through holes can easily allow the suture to be inserted and knotted for fixation, avoiding the occurrence of easy slippage.

[0004] However, the aforementioned patent documents only address the issue of reducing blockages in negative pressure drainage tubes. In practical applications, they do not address improvements in maintaining negative pressure within the drainage tubes. Consequently, the push-pull rods on the negative pressure drainage tubes are difficult to secure and prone to breakage. Furthermore, existing technologies lack a structure that allows for direct observation of whether negative pressure exists within the drainage tubes, making it impossible to quickly ascertain the negative pressure level. Additionally, the adhesive tape used to secure the drainage components is not secure, requiring repeated application. This results in an unsightly surface after repeated application of gauze dressings, and the large amount of medical tape used leads to material waste.

[0005] To address the aforementioned technical shortcomings, a solution is provided. Summary of the Invention

[0006] To overcome the aforementioned deficiencies of the prior art, this utility model provides a negative pressure drainage assembly that is easy to fix and replace. It utilizes a threaded tensioning mechanism and a clamping mechanism, and further incorporates a threaded groove on the push-pull rod of the negative pressure drainage tube. A rotating nut ring on the outside of the negative pressure drainage tube controls the movement of the push-pull rod, enabling convenient control of its position and self-locking. This facilitates maintaining negative pressure within the drainage tube. The feedback generated by directly pulling the nut ring allows for quick assessment of the negative pressure within the tube. Furthermore, a hook clamp is installed on the outer wall of the drainage tube, and the combination of the hook clamp and rubber sleeve allows the tube to be fixed in place, reducing the need for medical tape and avoiding waste of consumables. This addresses the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a negative pressure drainage component that is easy to fix and replace, including a negative pressure drainage tube, a piston is provided inside the negative pressure drainage tube, a threaded tensioning mechanism is provided inside the negative pressure drainage tube, and a sleeve mechanism is provided on the outer wall of the negative pressure drainage tube;

[0008] The threaded tensioning mechanism includes a push-pull rod rotatably mounted on one side of the piston. The push-pull rod extends out of the outer wall of the negative pressure drainage tube and is set in a horizontal position. A push-pull plate is fixedly mounted on one side of the push-pull rod and is set perpendicular to the push-pull rod. A threaded groove is opened on the outer wall of the push-pull rod and extends out of the outer wall of the negative pressure drainage tube.

[0009] In a preferred embodiment, a nut ring is threadedly connected to the outer wall of the threaded groove. The nut ring and the push-pull rod are arranged perpendicular to each other. The nut ring is located on the outer wall of the negative pressure drainage tube. Push rods are fixedly installed on both outer walls of the nut ring, and the two push rods are arranged perpendicular to each other.

[0010] In a preferred embodiment, a plurality of telescopic plates are fixedly installed on one side of the nut ring. The plurality of telescopic plates are arranged in a ring at equal intervals around the outer circumferential surface of the negative pressure drainage tube. A rotating ring is fixedly installed on one side of the plurality of telescopic plates. The rotating ring is rotatably installed on the outer wall of the negative pressure drainage tube.

[0011] In a preferred embodiment, the clipping mechanism includes a fixing plate fixedly installed on the outer wall of the negative pressure drainage tube. The fixing plate is horizontally positioned, and a hook clamp is fixedly installed on the top of the fixing plate. The hook clamp is arc-shaped and horizontally positioned.

[0012] In a preferred embodiment, the outer wall of the hook clamp is provided with a rubber sleeve, the rubber sleeve is set in a horizontal position, the inner wall of the rubber sleeve is in contact with the outer wall of the hook clamp, and an adhesive backing is fixedly installed on the top of the rubber sleeve.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] By setting threaded grooves on the push-pull rod of the negative pressure drainage tube and controlling the movement of the push-pull rod by setting a rotating nut ring on the outside of the negative pressure drainage tube, the movement position of the push-pull rod can be easily controlled and a self-locking mechanism can be formed, which facilitates the maintenance of negative pressure in the negative pressure drainage tube. The feedback generated by directly pulling the nut ring to drive the push-pull rod can quickly determine the negative pressure status inside the negative pressure drainage tube. At the same time, by setting a hook clamp on the outer wall of the negative pressure drainage tube, the negative pressure drainage tube can be fixed by the rubber sleeve through the setting of the hook clamp and rubber sleeve, reducing the need for medical tape and avoiding waste of consumables.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Refer to the instruction manual appendix Figure 1 - Figure 5 A negative pressure drainage component that is easy to fix and replace, such as Figure 1 and Figure 2 As shown, it includes a negative pressure drainage tube 1, a piston 2 is installed inside the negative pressure drainage tube 1, a threaded tensioning mechanism 3 is installed inside the negative pressure drainage tube 1, and a sleeve mechanism 4 is installed on the outer wall of the negative pressure drainage tube 1.

[0023] like Figure 3 and Figure 4 As shown, the threaded tensioning mechanism 3 includes a push-pull rod 31 rotatably mounted on one side of the piston 2. The push-pull rod 31 extends out of the outer wall of the negative pressure drainage tube 1 and is set in a horizontal state. A push-pull plate 32 is fixedly mounted on one side of the push-pull rod 31. The push-pull plate 32 and the push-pull rod 31 are set perpendicular to each other. A threaded groove 33 is opened on the outer wall of the push-pull rod 31. The threaded groove 33 extends out of the outer wall of the negative pressure drainage tube 1. Through the joint action of the push-pull plate 32 and the push-pull rod 31, the piston 2 can be pulled to move, thereby generating negative pressure in the negative pressure drainage tube 1.

[0024] like Figure 3 and Figure 4 As shown, a nut ring 34 is threadedly connected to the outer wall of the threaded groove 33. The nut ring 34 and the push-pull rod 31 are arranged perpendicularly to each other. The nut ring 34 is located on the outer wall of the negative pressure drainage pipe 1. Push rods 35 are fixedly installed on the outer walls of both sides of the nut ring 34. The two push rods 35 are arranged perpendicularly to each other. By moving the push rods 35 on both sides, the nut ring 34 is driven to rotate. Then, the nut ring 34 rotates with the threaded groove 33, causing the push-pull rod 31 to move backward and form a self-locking mechanism, which makes it easy for the negative pressure drainage pipe 1 to maintain negative pressure.

[0025] like Figure 3 and Figure 4 As shown, multiple telescopic plates 36 are fixedly installed on one side of the nut ring 34. The multiple telescopic plates 36 are arranged in a ring at equal intervals around the outer circumference of the negative pressure drainage tube 1. A rotating ring 37 is fixedly installed on one side of the multiple telescopic plates 36. The rotating ring 37 is rotatably installed on the outer wall of the negative pressure drainage tube 1. When the nut ring 34 rotates, it drives the multiple telescopic plates 36 and the rotating ring 37 to rotate synchronously. When pulling backward to check whether there is negative pressure in the negative pressure drainage tube 1, the nut ring 34 can pull the multiple telescopic plates 36 to extend synchronously, thus preventing the nut ring 34 from directly detaching.

[0026] like Figure 2 and Figure 5 As shown, the clip mechanism 4 includes a fixing plate 41 fixedly installed on the outer wall of the negative pressure drainage tube 1. The fixing plate 41 is set in a horizontal state. A hook clamp 42 is fixedly installed on the top of the fixing plate 41. The hook clamp 42 is set in an arc shape and is set in a horizontal state. The hook clamp 42 is fixed to the top outer wall of the negative pressure drainage tube 1 by the fixing plate 41.

[0027] like Figure 5 As shown, the outer wall of the hook clamp 42 is provided with a rubber sleeve 43, which is set horizontally. The inner wall of the rubber sleeve 43 is in contact with the outer wall of the hook clamp 42. An adhesive backing 44 is fixedly installed on the top of the rubber sleeve 43. By attaching the rubber sleeve 43 to the appropriate position of the head gauze dressing with the help of the adhesive backing 44, and then inserting the rubber sleeve 43 into the hook clamp 42 for fixation, it is easy to fix the negative pressure drainage tube, reduce the need for medical tape, and avoid waste of consumables.

[0028] The working process and principle of this utility model are as follows:

[0029] By actuating the push rods 35 on both sides, the nut ring 34 is rotated. The nut ring 34 rotates with the threaded groove 33, causing the push-pull rod 31 to move backward and form a self-locking mechanism. That is, the push-pull plate 32 and the push-pull rod 31 work together to pull the piston 2 to move. Thus, the piston 2 generates and maintains a negative pressure state in the negative pressure drainage tube 1. At the same time, when the nut ring 34 rotates, it drives multiple telescopic plates 36 and rotating ring 37 to rotate synchronously. When the nut ring 34 pulls the piston 2 backward to check whether there is negative pressure in the negative pressure drainage tube 1, the nut ring 34 can simultaneously pull multiple telescopic plates 36 to extend, thus preventing the nut ring 34 from directly detaching.

[0030] Furthermore, the rubber sleeve 43 can be attached to the appropriate position of the head gauze dressing with the help of the adhesive backing 44, and then the rubber sleeve 43 can be inserted and fixed by the hook clamp 42, which facilitates the fixation of the negative pressure drainage tube, reduces the need for medical tape, and avoids the waste of consumables.

[0031] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
