BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Figure 1 This is one of the structural diagrams of the present utility model;

[0016] Figure 2 This is the second structural diagram of the present utility model (the fixing belt is not shown);

[0017] Figure 3 This is the third structural diagram of the present invention (the fixing belt is not shown). DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0019] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0020] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0021] Reference Figure 1-3, an arterial catheter hand fixator, comprising a bracket body 1, wherein the bracket body 1 includes a back of the hand 2 located on the back of the hand, a tiger's mouth part 3 located at the base of the thumb and a palm part 4 located on the palm side. The back of the hand 2, the tiger's mouth part 3 and the palm part 4 are an integrated structure, forming a shape that fits the hand, can well adapt to the patient's hand, and can greatly improve comfort; a first fixing strap 12 for fixing at the wrist and a second fixing strap 7 for fixing at the forearm are provided on the back of the hand 2, and a flexible clamping tube 8 is provided on the flexible clamping tube 8. A mounting groove 9 for inserting an infusion tube is provided on the flexible clamping tube 8, and the infusion tube is mounted in the flexible clamping tube from the mounting groove. The friction between the flexible clamping tube and the infusion tube can well prevent the infusion tube from sliding, thereby causing bleeding at the needle port or needle falling off, especially for patients with moist skin or fever and sweating. The existing adhesive tape method is easy to loosen, causing the arterial catheter to loosen.

[0022] After the bracket body 1 is installed on the patient's hand, the bracket body 1 must not cover the patient's artery to avoid affecting the needle insertion. When the patient naturally puts down his arm, the needle insertion position will generally be exposed to avoid squeezing the needle tip. This posture is generally when the ulnar side of the arm is in contact with the armrest of the chair (or the surface of the bed), and the palm part 4 is located on the palm side of the arm to ensure that when the patient naturally puts down his arm, the palm part 4 will not be pressed.

[0023] The tiger's mouth part 3 is composed of a flexible sleeve and a shaping strip located inside the flexible sleeve. The shaping strip is fixed inside the flexible sleeve. The shape of the shaping strip can be adjusted to change the overall shape of the tiger's mouth part 3, so that it can better adapt to the hand shapes of different patients. It has strong applicability and is suitable for a wide range of people.

[0024] In addition, the back of the hand 2 can also adopt the structure of the tiger's mouth 3 to make it plastic, which can further improve its applicability.

[0025] The hardness of the back of the hand 2 and the palm 4 is greater than that of the base of the thumb 3 , thereby improving the stability of the first fixing belt 12 and the second fixing belt 7 after being fixed.

[0026] The back of the hand 2 and the palm of the hand 4 that are in contact with the skin are both provided with a flexible layer, making it more comfortable to use.

[0027] The flexible clamping tubes 8 are symmetrically arranged on both sides of the back of the hand 2, so that the product can be used for both hands.

[0028] The inner diameter of the flexible clamping tube 8 is slightly larger than the outer diameter of the infusion tube, and the size of the embedding groove 9 is smaller than the outer diameter of the infusion tube. When installing the infusion tube, a certain amount of force is required to open the embedding groove 9 so that the infusion tube enters the flexible clamping tube 8. When adjusting the position of the infusion tube, if the length reserved for the needle is insufficient (i.e., the length after extending from the flexible clamping tube 8), the needle will be pulled, or if the length reserved for the needle is too large, a force will appear to push the needle. In this case, medical staff will need to use greater force to directly pull the infusion tube so that the infusion tube moves slightly in the flexible clamping tube 8, thereby adjusting the appropriate state.

[0029] The bracket body 1 and the flexible clamping tube 8 are an integrated structure. The flexible clamping tube 8, the flexible sleeve of the tiger's mouth 3, and the flexible layer are all made of silicone material. The flexible clamping tube 8 is made of transparent material, so the condition of the infusion tube can be clearly observed.

[0030] During production, the back of the hand 2 and the palm of the hand 4 are first injection molded (the two ends of the molding strip are fixed on the back of the hand 2 and the palm of the hand 4, and the molding strip can be fixed in the mold for molding the back of the hand 2 and the palm of the hand 4, and then the back of the hand 2 and the palm of the hand 4 are injection molded. After the injection molding is completed, the molding strip is fixed to the back of the hand 2 and the palm of the hand 4, or corresponding mounting holes are provided on the back of the hand 2 and the palm of the hand 4 after the injection, and the molding strip is fixed to the back of the hand 2 and the palm of the hand 4 by adhesives or the like), and then the back of the hand 2 and the palm of the hand 4 of the bracket body 1 are placed on another mold, and the silicone material is injected to form the flexible clamping tube 8, the flexible sleeve of the tiger's mouth 3, and the flexible layer. This production method can make this product form an integrated structure, which belongs to the existing production process.

[0031] The back of the hand 2 is provided with a first fixing ring 10 and a second fixing ring 11. The front end of the first fixing belt 12 is fixedly connected to the first fixing ring 10. The first fixing belt 12 surrounds the wrist and passes through the second fixing ring 11 and then turns back. The front end of the first fixing belt is attached to the back (such as Figure 1 (as shown in A in the figure).

[0032] The back of the hand 2 is provided with a third fixing ring 5 and a fourth fixing ring 6, the front end of the second fixing belt 7 is fixed to the third fixing ring 5, the second fixing belt 7 is wrapped around the forearm of the arm and passes through the fourth fixing ring 6 and then folded back, and the front end of the second fixing belt 7 is attached to the back (as shown in FIG. Figure 1 (as shown in B in the figure).

[0033] The first fixing strap 12 and the second fixing strap 7 are Velcro straps with a hook side and a fleece side, wherein the fleece side is the side in contact with the skin. When the first fixing strap 12 and the second fixing strap 7 are folded back, the hook side and the fleece side can be fitted together to achieve a fixing effect.

[0034] Since the first fixing belt 12 and the second fixing belt 7 need to pass around the palm 4, sliding is likely to occur between the first fixing belt 12, the second fixing belt 7 and the palm 4, so an adhesive layer 13, i.e., the hook surface of Velcro, is provided on the palm 4, and part of the first fixing belt 12 and part of the second fixing belt 7 are in contact with the adhesive layer 13, wherein the function of the adhesive layer 13 is to limit the movement of the first fixing belt 12 and the second fixing belt 7.

[0035] The first fixing ring 10 , the second fixing ring 11 , the third fixing ring 5 and the fourth fixing ring 6 can be arranged on the surface of the back of the hand 2 (the side away from the skin), or on both sides of the back of the hand 2 .

[0036] In addition, the first fixing ring 10, the second fixing ring 11, the third fixing ring 5 and the fourth fixing ring 6 can be replaced with the adhesive layer 13 (the position of the adhesive layer 13 needs to be adjusted to achieve the effect of convenience for medical staff to use), and the first fixing belt 12 and the second fixing belt 7 are directly connected to the corresponding adhesive layer 13, which can also have a fixing effect and can adjust the position, with better flexibility. Multiple first fixing belts 12 and second fixing belts 7 can be pasted, and the stability is also better.
