[0002] When hospitals are giving patients infusions, they need to fix the catheters. Currently, medical catheters are generally fixed to the patient's body by wrapping them with medical tape.

[0003] Chinese patent document CN213760114U discloses a nursing catheter fixing device, including a mounting plate, the mounting plate is arc-shaped, the rear end of the upper surface of the mounting plate is fixedly connected to a first base plate, the left side of the first base plate is hinged with a first cover plate by a hinge, a small catheter fixing groove and a large catheter fixing groove are provided in the middle of the surface of the first base plate and the middle of the bottom surface of the first cover plate, and the front end of the upper surface of the mounting plate is fixedly connected to a second base plate. The utility model arranges a reset spring inside the mounting box, arranges movable plates at both ends of the reset spring, and arranges a limit column on the surface of the movable plate. When the cover plate is fixed, it is only necessary to pass the limit column through the first plug hole and the second plug hole in turn. When the cover plate needs to be separated from the base plate, it is only necessary to squeeze the protective cover. The fixing and disassembly are very simple, and it is worthy of universal application and promotion.

[0004] However, the device cannot be adapted to catheters of different sizes when actually used, and the device has relatively low applicability. In addition, the device may rotate on the patient's arm when used, resulting in relatively low stability of the device. Utility Model Content

[0005] The main purpose of the utility model is to provide a nursing catheter fixing device, which can effectively solve the problems of relatively low applicability and relatively low stability of the device.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0011] Preferably, when the two magnets are in contact, the arc plate 2 is in a compressed state, and the clamping plate 2 is parallel to the clamping plate 1.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The catheter fixing device adopts a design of multiple friction strips, which can increase the friction between the mounting plate and the patient's arm, and also prevent the device from rotating on the patient's arm, thereby causing the needle to fall off and affecting the normal operation of the device, making the device more stable when in use. At the same time, the design of the spring telescopic rod enables the device to fix catheters of different sizes when in use, and also reduces the deformation of the catheter, increasing the stability of the device when in use.

[0014] 2. This catheter fixing device adopts a design in which a magnet and an arc plate 2 cooperate with each other. By utilizing the mutual cooperation between the two magnets, the device can allow the arc plate 1 and the fixing groove to clamp the catheter when in use. At the same time, the elastic design of the arc plate 2 can facilitate the removal and placement of the catheter. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 - Figure 6 As shown, a nursing catheter fixing device comprises a mounting plate 1, and elastic bands 11 for fixing to the patient's arm are fixed to both left and right ends of the mounting plate 1. The design of the elastic band 11 enables the device to be suitable for patients of different body shapes when in use. A plurality of friction strips 12 are fixed to the lower end of the mounting plate 1, such as Figure 3 As shown, multiple friction strips 12 are parallel to the patient's arm. The multiple friction strips 12 are designed to be parallel to the patient's arm, which can increase the friction between the mounting plate 1 and the patient's arm, and also prevent the device from rotating on the patient's arm, thereby causing the needle to fall off and affecting the normal operation of the device. A clamping plate 13 is fixed to the upper end of the mounting plate 1, and two groups of support blocks 14 are fixed to the left side of the upper end of the clamping plate 13.

[0024] Specifically, the number of support blocks 14 in each group is two, and a rotating block 15 is installed between the two support blocks 14 in the same group so as to rotate together. A clamping plate 2 16 is fixed to the upper ends of the two rotating blocks 15. The clamping plate 2 16 cooperates with the support block 14 and the rotating block 15 so that the clamping plate 2 16 can be rotatably connected relative to the clamping plate 1 13, and at the same time, a gap can be left between the clamping plate 2 16 and the clamping plate 1 13 when they are parallel to each other, so as to facilitate the placement of the catheter. Two groups of spring telescopic rods 17 are fixed to the lower end of the clamping plate 2 16. The spring telescopic rods 17 are existing technologies, so that the device can be suitable for catheters of different sizes when fixing the catheter.

[0025] like Figure 1 and Figure 4 As shown, the number of each group of spring telescopic rods 17 is two, and the two spring telescopic rods 17 can better fix the catheter. An arc plate 18 is fixed to the output end of the spring telescopic rod 17, and two fixing grooves 19 for placing the catheter are also provided on the upper end of the clamping plate 13. Through the mutual cooperation between the arc plate 18 and the fixing groove 19, the device can fix catheters of different sizes when in use, and at the same time, the degree of deformation of the catheter can also be reduced.

[0026] like Figure 4 - Figure 6As shown, an arc plate 22 is fixed to the left side of one end where the clamping plate 2 16 and the clamping plate 1 13 are close to each other. The arc plate 22 is made of elastic metal material, including but not limited to elastic steel, iron, aluminum, etc., which can facilitate the rotation of the clamping plate 2 16, thereby facilitating the taking and placing of the catheter. A magnet 21 is fixed to the right side of one end where the clamping plate 2 16 and the clamping plate 1 13 are close to each other. When the two magnets 21 are in contact, the arc plate 22 is in a compressed state, and the clamping plate 2 16 is parallel to the clamping plate 13, so that when the two magnets 21 are in contact, the arc plate 18 and the fixing groove 19 can clamp the catheter. When the two magnets 21 are not in contact, due to the elastic characteristics of the arc plate 22, the clamping plate 2 16 can be rotated, thereby facilitating the taking and placing of the catheter.

[0027] The specific implementation of this embodiment is as follows: when the device is used, the device is put on the patient's wrist, and the two magnets 21 only need to be separated. Due to the elasticity of the arc plate 22 itself, the clamping plate 16 is rotated, and then the catheter to be fixed is placed in the fixing groove 19. The operator rotates the clamping plate 16 to make the two magnets 21 contact each other.

[0028] When the clamping plate 2 16 rotates toward the side close to the clamping plate 1 13 , the arc plate 18 cooperates with the fixing groove 19 to clamp the catheter. At the same time, due to the characteristics of the spring telescopic rod 17 , the device can be used for catheters of different sizes when in use.

[0029] It should be noted that the specific installation method, circuit connection method and control method of the elastic band 11, the spring telescopic rod 17 and the magnet 21 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
