Description

Technical Field

[0001] This utility model belongs to the field of medical and nursing technology, and specifically relates to a catheter fixation device for the care of hematological diseases. Background Technology

[0002] For serious hematological diseases such as leukemia and lymphoma, chemotherapy is an important treatment. Peripherally inserted central catheters (PICCs) are now widely used in clinical practice. This involves inserting a catheter through a vein in the arm, directly into a large vein near the heart. This avoids direct contact between chemotherapy drugs and the arm veins. Furthermore, the rapid blood flow in the large vein quickly dilutes the chemotherapy drugs, preventing vascular irritation, reducing patient pain, and improving quality of life.

[0003] When blood patients undergo PICC line insertion and are showering or receiving other care, to prevent the dressing inside the puncture site from getting wet and causing infection, a silicone waterproof sleeve is usually placed on the outside of the patient's arm outside the PICC line. The two ends of the waterproof sleeve fit snugly against the blood patient's arm to prevent water from entering. However, the seal between the two ends of the waterproof sleeve and the blood patient's arm is not very reliable. When the blood patient's arm moves during showering, the ends of the waterproof sleeve are stretched and deformed, making it easy for external water to be sucked into the sleeve, which is not easily noticed.

[0004] Therefore, there is a need to design a catheter fixation device for hematological care that can provide multiple seals, reduce the risk of wound infection, improve reliability, and detect water ingress in a timely manner to solve the current technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a catheter fixation device for hematological care that offers multiple seals, reduces the risk of wound infection, improves reliability, and enables timely detection of water ingress in the early stages.

[0006] The technical solution of this utility model is: a catheter fixation device for hematological disease care, including an elastic sleeve, a flexible protective sleeve is fitted on the outer side of the elastic sleeve, and transparent sealing cylinders are provided at both ends of the flexible protective sleeve. An elastic sealing airbag, a water-absorbing color-changing ring and at least one conical elastic cuff are sequentially arranged on the sealing cylinder from one end away from the flexible protective sleeve to the other end.

[0007] The interior of the elastic sealing airbag is uniformly provided with at least two annular sealing cavities protruding from the inner surface of the elastic sealing airbag along its axial direction. The annular sealing cavities are connected to the elastic sealing airbag and are integrated into a single structure.

[0008] The inner diameter of the tapered elastic cuff is 0.1 to 1 cm smaller than the inner diameter of the elastic sealing airbag, and the outer side of the tapered elastic cuff is connected to the inside of the sealing cylinder to form an integral structure.

[0009] The sealed cylinder has two tapered elastic cuffs inside.

[0010] The water-absorbing color-changing ring is a ring-shaped structure made of water-absorbing color-changing fabric, and the water-absorbing color-changing ring is bonded and fixed to the inside of the sealing cylinder.

[0011] Both ends of the flexible protective sleeve are provided with cones, and the sealing sleeve is provided on the cone at one end away from the flexible protective sleeve. The flexible protective sleeve, cone, and sealing sleeve are connected to form an integral structure.

[0012] A pipe connector is provided on one side of the flexible sleeve, which is used to connect to an external hose.

[0013] The beneficial effects of this utility model are: (1) In this utility model, the elastic sealing airbag and at least one conical elastic cuff form at least two seals between the sealing cylinder and the patient's arm, thereby improving the sealing effect and sealing reliability. (2) During use, the color of the water-absorbing color-changing ring can be observed in real time through the transparent sealing tube. When water enters the elastic sealing airbag, the water will be absorbed by the water-absorbing color-changing ring to prevent it from entering further. At the same time, the water-absorbing color-changing ring changes color after absorbing water. The color change of the water-absorbing color-changing ring can be detected in time through the transparent sealing tube so as to handle it in time and avoid contaminating the puncture site. (3) Before putting on the flexible sleeve, wrap the PICC tube with an elastic sleeve and fix it to the patient's arm. This can reduce the impact on the PICC tube when putting on the flexible sleeve.

[0019] like Figures 1 to 3 As shown, the catheter fixation device for hematological nursing includes an elastic sleeve 1, a flexible sleeve 2 fitted on the outer side of the elastic sleeve 1, and transparent sealing sleeves 4 at both ends of the flexible sleeve 2. An elastic sealing airbag 5, an absorbent color-changing ring 6, and at least one conical elastic cuff 7 are sequentially arranged on the sealing sleeve from one end away from the flexible sleeve 2 towards the other end. In this embodiment, when using the catheter fixation device for hematological nursing, the elastic sleeve 1 is first removed from inside the flexible sleeve 2 and fitted onto the PICC tube on the outside of the patient's arm. The elastic sleeve 1 wraps and fixes the PICC tube to the patient's arm. Then, the sealing sleeve 4 and the flexible sleeve 2 are fitted onto the outside of the patient's arm, aligning the PICC tube with the flexible sleeve 2. The elastic sealing airbag 5 and at least one conical elastic cuff 7 are located inside the sealing sleeves 4 at both ends of the flexible sleeve 2. The tapered elastic cuff 7 is tightly sealed to the outside of the patient's arm. During use, the color of the absorbent color-changing ring 6 can be observed in real time through the transparent sealing cylinder 4. When water enters the elastic sealing airbag 5, the water will be absorbed by the absorbent color-changing ring 6, preventing it from entering further. At the same time, the absorbent color-changing ring 6 changes color after absorbing water, which can be detected in time through the transparent sealing cylinder 4 for timely treatment and to avoid contaminating the puncture site. The elastic sealing airbag 5 and at least one tapered elastic cuff 7 form at least two seals between the sealing cylinder 4 and the patient's arm, improving the sealing effect and reliability. Before putting on the flexible sleeve 2, the PICC tube is first wrapped and fixed to the patient's arm with the elastic sleeve 1, which can reduce the impact on the PICC tube when the flexible sleeve 2 is put on later.

[0020] In some embodiments, at least two annular sealing cavities 51 protruding from the inner surface of the elastic sealing airbag 5 are uniformly arranged along its axial direction inside the elastic sealing airbag 5. The annular sealing cavities 51 are connected to the elastic sealing airbag 5 and formed as an integral structure. The at least two annular sealing cavities 51 protruding from the inner surface of the elastic sealing airbag 5 can further improve the sealing effect. Specifically, the elastic sealing airbag 5 is an annular hollow closed elastic airbag made of silicone material, which is pre-filled with air. The annular sealing cavities 51 and the elastic sealing airbag are integrally formed.

[0021] In some embodiments, the inner diameter of the tapered elastic cuff 7 is 0.1 to 1 cm smaller than the inner diameter of the elastic sealing airbag 5. The outer side of the tapered elastic cuff 7 is connected to the inside of the sealing cylinder 4 to form an integral structure. The inner diameter of the tapered elastic cuff 7 is smaller than the inner diameter of the elastic sealing airbag 5, so that when it is put on the patient's arm, it can fit tightly against the outside of the patient's arm to ensure a sealing effect. Preferably, the inner diameter of the tapered elastic cuff 7 is 1 cm smaller than the inner diameter of the elastic sealing airbag 5.

[0022] In some embodiments, the interior of the sealing cylinder 4 is provided with two tapered elastic cuffs 7, which can further improve the reliability of the seal compared to a single tapered elastic cuff 7.

[0023] In some embodiments, the water-absorbing color-changing ring 6 is a ring-shaped structure made of water-absorbing color-changing fabric, and the water-absorbing color-changing ring is bonded and fixed to the inside of the sealing cylinder 4; specifically, the water-absorbing color-changing ring 6 is made of rectangular water-absorbing color-changing fabric rolled into a roll, and then the two ends of the roll of water-absorbing color-changing fabric are bonded or sewn together to form a ring, and then bonded to the inside of the sealing cylinder 4.

[0024] In some embodiments, both ends of the flexible sleeve 2 are provided with cones 3, and the sealing cylinder 4 is provided on one end of the cone 3 away from the flexible sleeve 2. The flexible sleeve 2, cone 3 and sealing cylinder 4 are connected to form an integral structure. Specifically, the flexible sleeve 2, cone 3 and sealing cylinder 4 are an integral structure made of silicone material.

[0025] In some embodiments, a pipe connector 11 is provided on one side of the flexible sleeve 2. The pipe connector 11 is used to connect to an external hose. One end of the external hose is connected to the pipe connector 11, and the other end of the external hose is fixed in a dry place. When showering, the flexible sleeve 2 will be continuously squeezed or stretched, causing changes in internal air pressure. When the internal air pressure is low, it is easy to draw water from the outside into its interior, increasing the risk of infection at the puncture site. By connecting the external hose through the pipe connector 11, the interior of the flexible sleeve 2 is connected to the outside atmosphere, ensuring that the internal and external air pressures are consistent and preventing water from entering due to changes in air pressure.
