Description

Technical Field

[0001] The present invention relates to the technical field of catheter fixing, and in particular to a convenient PICC catheter fixing device. Background Art

[0002] PICC catheterization is the insertion of a central venous catheter through a peripheral vein. PICC catheterization is a safe and effective catheterization technique that is very common in clinical practice. During the operation, venous puncture is generally performed through the basilic vein and the median cubital vein. The PICC catheter is inserted into the middle and lower segments of the superior vena cava through the introduction sheath to meet the needs of irritating drugs or long-term large-volume infusion, reduce drug stimulation to blood vessels, and reduce peripheral vein puncture, which is beneficial to protecting peripheral veins.

[0003] Patients with PICC catheters should undergo standardized PICC catheter care during the catheter indwelling period to ensure catheter safety, prevent complications, and prevent tube removal. In particular, correct fixation of the exposed part of the catheter can effectively prevent unplanned extubation.

[0004] Because the exposed tube of the PICC catheter is mostly a thin tube, the existing transparent dressing can fix it well. However, the connector at the end of the PICC catheter is hard and protruding. It is attached to the patient's skin together with the transparent dressing. When the arm moves, the skin near the joint is squeezed, which can easily cause the catheter connector to move and increase the tension of the transparent dressing. This is especially true for infants and young children with relatively short arms, relatively frequent movements, and tender skin. The connector will significantly squeeze the skin, causing mechanical pressure injuries to the patient's skin. At the same time, PICC catheters made of non-silicone materials are less flexible than silicone catheters. The exposed part of the catheter is directly attached to the skin through a transparent dressing. If the exposed part of the catheter is placed in an improper shape or position and the transparent dressing is not firmly fixed, it will cause the catheter to move and the tube to form an angle. Over time, it will cause the tube to break and infusion leakage to occur. However, if the adhesive strength is reduced, the exposed part of the PICC catheter may move during its indwelling period, causing the catheter to fall out or be swallowed into the body, which may lead to related complications. If the catheter is swallowed into the body for more than 3 cm, the tip will enter the atrium, causing arrhythmia, discomfort in the precordial area, etc., and the probability of bloodstream infection will also increase due to the external catheter entering the body. Summary of the Invention

[0005] The present invention aims to provide a convenient PICC catheter fixing device to solve the problems that the existing PICC catheter fixing method easily causes the catheter connector to move, mechanically pressurize the skin, and move or damage the exposed tube body.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution: comprising a device body, the top end of which is inclined; a fixing block hingedly connected to the top end of the device body, the bottom end of the fixing block being fixedly connected to a clamping block; a buckle provided on the device body and used to cooperate with the clamping block to achieve closure of the fixing block; a clamping slot provided at the top end of the device body and the bottom end of the fixing block, used to accommodate a connector of a PICC catheter; a fixing groove provided in the clamping slot, used to fix a recessed portion of the connector of the PICC catheter; and a connecting device fixedly connected to the bottom end of the device body, used to fix the device to the patient's body.

[0007] Preferably, the connecting device is an adhesive patch.

[0008] Preferably, the clamping block comprises a spring sheet, the inner end of the spring sheet is fixedly connected to the connecting block, and the buckle comprises a plurality of connecting holes vertically arranged on the outer wall of the device body and cooperating with the connecting block.

[0009] The principle and beneficial effects of this technical solution:

[0010] The device features a hinged fixing block design. The bottom block mates tightly with the buckle on the device body, allowing for flexible opening and closing of the fixing block for easy operation. The device body and fixing block are each equipped with a slot for securing the PICC catheter connector, ensuring that the catheter is stable and resists movement during use. The tilted top of the device body creates a smooth transition, allowing for a better fit between the device, catheter, transparent dressing, and skin, further enhancing fixation.

[0011] The large adhesive patch at the bottom of the device effectively disperses pressure, preventing skin damage caused by excessive localized pressure. It also enhances adhesive strength, preventing complications such as tubing dislodged or swallowed due to external forces. By tightly securing the catheter connector, the tubing adheres closely to the skin, minimizing movement. The connector actively lifts, preventing tubing breakage and fluid leakage caused by bending and wear.

[0012] This technical solution has a simple structure and is easy to operate. It is particularly suitable for active patients such as children. It can significantly improve the safety and stability of PICC catheter fixation, reduce the risk of catheter-related complications, and provide an efficient and reliable solution for clinical nursing work.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0017] Example:

[0018] like Figure 1 and Figure 2 As shown, the present invention provides a convenient PICC catheter fixing device, comprising a device body 1, a fixing block 2, a card block 3, a buckle 4, a card slot 5, a fixing slot 6 and an adhesive sheet 7. The top of the device body 1 is connected to the fixing block 2 in a hinged manner, and the bottom end of the fixing block 2 is fixedly connected to the card block 3. The device body 1 is provided with a buckle 4 that cooperates with the card block 3, and the opening and closing operation of the fixing block 2 is achieved through the cooperation between the card block 3 and the buckle 4. Card slots 5 are provided at the top of the device body 1 and the bottom end of the fixing block 2. A fixing slot 6 is further provided in the card slot 5 for respectively fixing the connector of the PICC catheter and the recessed part of the connector. An adhesive sheet 7 is fixedly connected to the bottom end of the device body 1 for firmly sticking the entire fixing device to the patient's body. In addition, the top of the device body 1 is inclined to better fit the device, catheter, transparent dressing and skin.

[0019] Specific usage process

[0020] Medical personnel follow the conventional PICC catheterization procedure to insert the PICC catheter into the patient. After the catheter is inserted, the inclined bottom end of the fixing device of the present invention is directed toward the puncture site. Fixing block 2 is opened, and the exposed tube body and connector of the PICC catheter are slightly lifted, and the connector is placed into slot 5. The recessed portion of the catheter connector is accurately placed in fixing slot 6, ensuring that the connector maintains the appropriate lifting angle after being fixed to avoid bending and abrasion of the tube, which may cause damage to the tube body.

[0021] After placing the PICC catheter connector, close the fixing block 2. The locking block 3 at the bottom of the fixing block 2 engages with the buckle 4 on the device body 1, firmly securing the catheter connector inside the device. This ensures the stability of the catheter after it is fixed and prevents accidental movement of the catheter due to external forces.

[0022] Adhere the adhesive patch 7 at the bottom of the device body 1 to the patient's body. The large surface area of ​​the adhesive patch 7 effectively distributes pressure, preventing mechanical skin injuries caused by the connector moving against the skin due to arm movement. Furthermore, the large surface area of ​​the adhesive patch ensures adhesion strength between the fixation device and the skin, further improving the reliability of catheter fixation.

[0023] After the fixator is fixed to the appropriate part of the skin, use transparent dressing to fix the exposed catheter and fixation device without tension.

[0024] Through the above-mentioned embodiments, the portable PICC catheter fixing device of the present invention can effectively solve the problems existing in the prior art. First, the device fixes and supports the connector and the exposed tube body of the catheter. The exposed tube body part can completely fit the skin and is not easy to move, while the connector can be actively lifted and maintained at a suitable angle to avoid damage to the tube body and leakage of infusion caused by bending and wear of the tube. Secondly, the inclined design of the top of the device body enables the transparent dressing to fit well with the device body, catheter and skin, further improving the fixing effect. In addition, the large-area design of the adhesive patch can effectively disperse pressure and prevent mechanical compression of the skin, while ensuring the adhesive strength to avoid complications caused by the tube body falling out or being swallowed into the body.

[0025] The above is only an embodiment of the present invention, and common knowledge such as the specific technical solutions or characteristics in the solution is not described in detail here. For those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the description can be used to interpret the content of the claims.
