[0002] Infusion apparatus is a kind of common medical instrument, mainly for liquid (such as physiological saline, glucose solution, drug solution etc.) is directly input into the blood circulation system of patient. Infusion apparatus indwelling needle is a kind of medical equipment commonly used in intravenous infusion therapy, it combines the function of infusion apparatus and indwelling needle, for long time, repeated intravenous infusion.

[0003] Intravenous indwelling needle is widely used in infusion process in clinical medicine, especially in surgical patients, its usage rate is as high as more than 99%. However, the use of such indwelling needle also has some potential problems. For example, it can cause unnecessary compression to the arm of the patient, especially in the case of long time keeping still of the arm of the patient, which often leads to local muscle pain of the arm. For those patients who are active at night and prone to move around, they may inadvertently compress the indwelling needle, which not only can cause additional harm to the patient, but also can cause the indwelling needle to shift or fall off, so a protective device capable of protecting infusion apparatus is needed to solve these problems. However, many existing infusion apparatus protectors use fixed size elastic material to be fixed on the wrist or arm of the patient. This fixing method may be suitable for standard size arms, but for people with thicker or thinner arms, it may be too tight or too loose, resulting in discomfort or insecure fixation.

[0004] Therefore, it is necessary to design an infusion apparatus protector with adjusting function. INVENTION CONTENTS

[0007] Further, the connecting block is arranged on the front side of the cover plate, and the clamping block is rotatably arranged on the front side of the placing frame and is clamped with the connecting block.

[0008] Further, the guiding cylinder is symmetrically arranged in the placing frame, the connecting rod is arranged in the guiding cylinder through the elastic member, and the pressing plate is arranged between the lower ends of the four connecting rods.

[0009] Further, the elastic member is a compression spring.

[0010] Further, the shape of the placing block is matched with the shape of the catheter assembly on the indwelling needle.

[0011] Further, the guiding cylinder is symmetrically arranged in the placing frame, the connecting rod is arranged in the guiding cylinder through the elastic member, and the pressing plate is arranged between the lower ends of the four connecting rods.

[0012] The utility model has the advantages and obvious progress that:

[0013] Through the design of the belt buckle positioning member, the adjusting hole and the limiting ring, the length of the fixing belt I and the fixing belt II can be appropriately adjusted according to the size of the hand circumference of different patients, so that appropriate protection is provided for different patients in the infusion process.

CONCRETE IMPLEMENTATION

[0018] The technical scheme of the utility model will be further described below with reference to the drawings.

[0019] Embodiment: a infusion protector with adjusting function, please see Figs. 1 to 3The utility model relates to a kind of protective device for infusion, including placing frame 1, connecting shaft 2, cover plate 3, placing block 4, connecting block 5, card block 6, fixed band I 7, fixed band II 8, belt buckle 9, positioning member 10, limiting ring 12, guide cylinder 13, connecting rod 14, pressing plate 15 and elastic member 16, the rear side of placing frame 1 is rotatably connected with cover plate 3 by connecting shaft 2, placing block 4 is connected in the left side center position of placing frame 1, the shape of placing block 4 is compatible with the shape of catheter assembly on the needle, connecting block 5 is connected in the front side center position of cover plate 3, card block 6 is rotatably connected in the front side center position of placing frame 1, card block 6 and connecting block 5 are engaged, fixed band I 7 is connected in the front side left-right symmetry of placing frame 1, fixed band II 8 is connected in the rear side left-right symmetry of placing frame 1, the tail end of two fixed band I 7 is connected with belt buckle 9, positioning member 10 is rotatably connected in the middle of belt buckle 9, adjusting hole 11 is evenly spaced and provided on two fixed band II 8, limiting ring 12 is sleeved in the lower end of fixed band I 7, guide cylinder 13 is connected in the inside left-right front-rear symmetry of placing frame 1, guide cylinder 13 is hollow structure, connecting rod 14 is connected in the inside of guide cylinder 13 by elastic member 16 as elastic connecting piece, pressing plate 15 is connected between the lower end of four connecting rods 14, and elastic member 16 is compression spring.

[0020] When patient is in infusion, medical staff should first prepare the protector, then place the side with placing block 4 towards palm direction, place placing frame 1 in the position to be fixed, i.e. above the wrist near infusion site, after placing, pass fixed band II 8 through limiting ring 12, and adjust the length of fixed band II 8 by pulling, to ensure that fixed band I 7 and fixed band II 8 can be stably bound on the wrist of patient, after adjusting to appropriate length, positioning member 10 is passed through corresponding adjusting hole 11 on fixed band II 8, to lock the position of fixed band I 7 and fixed band II 8. Same step is applied to fixed band I 7 and fixed band II 8 on the other side, to ensure uniform fixation on both sides. Through the combination design of belt buckle 9 positioning member 10, adjusting hole 11 and limiting ring 12, the length of fixed band I 7 and fixed band II 8 can be adjusted according to the size of different patient's girth, to ensure that appropriate protection is provided for different patients during infusion. After fixing, card block 6 is rotated to unlock, so that connecting block 5 can move.

[0021] Then, the medical staff can start to inject the intravenous needle at the predetermined position on the patient's wrist. The design of the placement block 4 is specially used for placing and supporting the catheter assembly of the intravenous needle, avoiding its movement during the infusion process. Then, the pressing plate 15 is pulled upward, driving the connecting rod 14 connected therewith to ascend along the guide cylinder 13, and the elastic member 16 is compressed. The infusion tube of the intravenous injector is gently placed into the placement frame 1, and then the pressing plate 15 is released. Under the action of the elastic member 16, the pressing plate 15 drives the connecting rod 14 to descend along the guide cylinder 13 and reset until the pressing plate 15 contacts with the infusion tube, thereby playing a role of stabilizing and positioning the infusion tube, effectively preventing the needle head of the intravenous needle from being displaced due to the random movement of the patient's hand.
