Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a drainage tube. Background Technology

[0002] A drainage tube is a medical device used in clinical surgery to drain pus, blood, and fluid accumulated between body tissues or in body cavities, preventing postoperative infection and promoting wound healing. The drainage tube is a PVC soft catheter with a round tip and an open suction area at the front end, marked with depth lines. It is sterilized with ethylene oxide and is for single use only.

[0003] Existing methods for fixing drainage tubes mainly include the following: 01. Adhesive tape fixation: Using adhesive tape or a special fixing device to fix the drainage tube to the patient's skin. It's difficult to maintain a certain tightness during fixation; too tight may cause patient discomfort or even affect local blood circulation; too loose may easily lead to the drainage tube loosening. 02. Abdominal binder fixation: Using an abdominal binder to ensure the drainage tube is secure. 03. "I" shaped fixation: Used to reduce pressure on the nasal ala and reduce damage to the nose from long-term indwelling gastric tubes. 04. Large "I" method: Following the SHEA-CAUTI guidelines, using tape to fix it in a suitable position.

[0004] Fixing the drainage tube is mainly to prevent local fluid and blood accumulation caused by displacement or dislodgement of the drainage tube, which increases the risk of infection and may even compress surrounding tissues, affecting the patient's breathing and swallowing.

[0005] Avoid directly applying tape to the interface: Avoid applying tape directly to the interface of the drainage tube to prevent the interface from becoming loose. Utility Model Content

[0006] The purpose of this utility model is to provide a drainage tube that, by adopting a fixing structure made of elastic rubber, can buffer the swinging force applied when connecting two or three joints of the drainage tube body, thus solving the problem of the drainage tube body not being firmly fixed due to the pulling force.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a drainage tube, comprising a drainage tube body and at least one elastic fixation dressing; the elastic fixation dressing comprises a rubber fixation seat and a medical dressing, the rubber fixation seat comprises a cylindrical body, a cross seat and a connecting post located between the cylindrical body and the cross seat; the cross seat is bonded to the medical dressing, and the cylindrical body is sleeved on the drainage tube body.

[0009] Furthermore, the drainage tube body includes a two-lumen drainage tube or a three-lumen drainage tube.

[0010] Furthermore, the cylinder body and the drainage tube body are interference-fitted.

[0011] Furthermore, the number of elastic fixation patches is in the range of 1-6.

[0012] Furthermore, the number of elastic fixation patches is two.

[0013] Furthermore, the bottom of the cross-shaped seat has several slots.

[0014] Furthermore, the connecting columns are arranged side by side between the cylinder and the cross seat.

[0015] Furthermore, the cross seat is a rubber plate cross-shaped structure.

[0016] Furthermore, the length of the connecting post is between 5mm and 10mm.

[0017] This utility model has the following beneficial effects:

[0018] This invention utilizes a fixing structure made of elastic rubber material, which can buffer the swinging force applied when connecting two or three joints of the drainage tube body. This effectively avoids the problem of the drainage tube body not being securely fixed due to pulling force. The deformation of the elastic connecting column buffers the pulling force of the drainage tube body on the elastic fixation dressing, thereby enhancing the stability and duration of use of the elastic fixation dressing.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present utility model.

[0031] Generally made of materials such as silicone rubber or polyurethane. During use, one end of the catheter is inserted into the body or the drainage site of the wound, while the other end can be connected externally to other external instruments such as drainage tubes. Drainage is achieved through pressure from within the body, gravity, or negative pressure suction. It is provided sterilely and is for single use. It is used to drain effusion, exudate, or gas from the patient's body. Common types include thoracic drainage catheters, ventricular drainage catheters, cerebrospinal fluid external drainage catheters, lumbar external drainage catheters, cranial external drainage catheters, abdominal drainage tubes, thoracic drainage tubes, ventricular drainage tubes, bile duct drainage tubes, and bile drainage tubes. Example

[0032] like Figure 1 As shown, this embodiment is a drainage tube, including a drainage tube body and two elastic fixation dressings.

During installation, the cylinder 401 of the elastic fixation dressing is inserted from the end of the two-lumen drainage tube 1. The elastic rubber deforms and limits its own position. After adjusting the position of the elastic fixation dressing, the sticker on the medical dressing 3 is peeled off and the medical dressing 3 is attached to the user's skin.

[0033] like Figure 5As shown, the elastic fixation dressing includes a rubber fixation base 4 and a medical dressing 3. By using a fixation structure made of elastic rubber, it can buffer the swinging force applied when connecting two or three joints of the drainage tube body, effectively avoiding the problem of the drainage tube body not being firmly fixed due to pulling force.

Through a row of rubber connecting posts 403, effective shaking between the cylinder 401 and the cross seat 402 can be achieved. The deformation of the connecting posts 403 can buffer the pulling force of the drainage tube body on the elastic fixation dressing, thereby enhancing the stability and duration of use of the elastic fixation dressing. Example

During installation, the cylinder 401 of the elastic fixation dressing is inserted from the end of the three-lumen drainage tube 2. The elastic rubber deforms and limits its own position. After adjusting the position of the elastic fixation dressing, the sticker on the medical dressing 3 is peeled off and the medical dressing 3 is attached to the user's skin.

[0037] like Figure 5 As shown, the elastic fixation dressing includes a rubber fixation base 4 and a medical dressing 3.

[0039] Among them, the cross seat 402 is a rubber plate cross-shaped structure. The bottom of the cross seat 402 has several slots 404. The rubber plate cross-shaped structure is used to facilitate fixing it to the medical dressing 3 with glue. The cross-shaped structure enhances the stability of the two forces in the vertical direction.

[0040] The connecting posts 403 are arranged side by side between the cylinder 401 and the cross seat 402. The length of the connecting posts 403 is 5mm-10mm. Through a row of rubber connecting posts 403, effective shaking between the cylinder 401 and the cross seat 402 can be achieved. The deformation of the connecting posts 403 can buffer the pulling force of the drainage tube body on the elastic fixation dressing, thereby enhancing the stability and duration of use of the elastic fixation dressing.

[0041] The cross seat 402 is a rubber plate cross-shaped structure. The bottom of the cross seat 402 has several slots 404. The slots 404 are arranged to enhance the adhesion between the cross seat 402 and the medical dressing 3. The rubber plate cross-shaped structure is used to facilitate fixing it to the medical dressing 3 with glue. The cross-shaped structure enhances the stability of the two forces in the vertical direction.
