Description

Technical Field

[0001] The utility model relates to the technical field of infusion auxiliary equipment, in particular to an infusion hand fixer. Background Art

[0002] During infusion, the needle needs to be accurately inserted into the blood vessel to ensure that the drug can smoothly enter the blood and circulate. Therefore, during infusion, the hands cannot be shaken or bent at will, otherwise the needle may be displaced or out of the blood vessel, causing the needle to move in the blood vessel, thereby stimulating the blood vessel wall and causing pain or discomfort. Especially for children and other patients with poor cooperation, in order to avoid random movement of the hands, their hands are usually fixed.

[0003] The fixing device currently used for infusion generally places the hand directly on the board, and then fixes the hand and the board with medical tape or gauze, but the needle insertion site is still directly exposed to the outside. However, since the patient may perform other actions during the infusion, such as taking things or going to the bathroom, they may inadvertently use the hand that is being infused, or some child patients may accidentally touch the needle due to curiosity or overreaction, resulting in displacement of the infusion needle and puncture of the blood vessel wall, etc., so that the intravenous puncture needs to be re-performed, causing secondary pain to the patient.

[0004] Therefore, we propose an infusion hand fixator to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] The utility model provides a hand fixer for infusion, comprising a supporting member 1, a finger locking member, a protective cover 2 and a locking member. The supporting member 1 comprises a hand support plate 11 and a wrist support plate 12 connected to the hand support plate 11 in a straight extension direction. The finger locking member is arranged on the hand support plate 11 to limit the random movement of the fingers. The protective cover 2 is movably connected to the hand support plate 11 to prevent accidental contact with the infusion needle. The locking member is arranged on the supporting member 1 to fix the protective cover 2 and the patient's hand on the supporting member 1. When in use, the hand is fixed to the supporting member 1. Place it on the hand support plate 11, and lock the fingers through the finger locking piece to prevent the blood vessels from being compressed due to bending of the fingers when the patient is receiving an infusion, thereby affecting the infusion effect. The protective cover 2 can protect the upper end of the infusion needle to prevent the needle from being accidentally hit or contaminated by the outside world, thereby improving the safety of infusion. At the same time, the protective cover 2 can be made of transparent material, which is convenient for medical staff to directly observe the status of the needle. The protective cover 2 is in the shape of a bridge arch or has an upward bulge inside, which can prevent the inside of the protective cover 2 from contacting the infusion needle when the protective cover 2 is covered on the hand support plate 11.

[0030] Among them, in the first embodiment of the utility model, as Figure 2 As shown, the protective cover 2 is hingedly connected to the hand support plate 11, an axial hole 3 is opened at the lower side of the protective cover 2, and an axle pin 31 is rotatably provided on the hand support plate 11, which passes through the axle hole 3 and is rotatably connected to the axle hole 3. Specifically, when in use, the hand is placed on the receiving part, and the hinge is used as the rotation center. The axle pin 31 is rotated inside the axle hole 3 to swing the protective cover 2 so that the protective cover 2 covers the top of the needle tip of the hand to provide a protective effect. This connection method prevents the protective cover 2 from being separated from the hand support plate 11, and also avoids the protective cover 2 from falling off or being lost.

[0031] In the second embodiment of the utility model, the same effect as the first embodiment can be produced, such as Figure 3 As shown, the protective cover 2 is slidably connected to the hand support plate 11, the lower end of the protective cover 2 is connected to a sliding bar 5, and the hand support plate 11 is provided with a sliding track 51 slidably connected to the sliding groove, which can also prevent the protective cover 2 from being separated from the hand support plate 11 and prevent the protective cover 2 from being lost.

[0032] like Figure 4As shown, in the third embodiment of the utility model, different from the first and second embodiments, the protective cover 2 is connected to the hand support plate 11 by snapping, and the lower end of the protective cover 2 is connected with a snap-in block 4, and the hand support plate 11 is provided with a snap-in groove 41 matching the snap-in block 4. After use, the snap-in block 4 is removed from the snap-in groove 41 so that the protective cover 2 can be separated from the hand support plate 11. The installation or removal of the protective cover 2 can be determined according to actual use requirements. However, compared with the hinged and sliding connection methods used in the first and second embodiments, the protective cover 2 is installed by a snap-in method. Although it is convenient for disassembly and separation, the protective cover 2 is easy to lose.

[0033] Preferably, the finger locking member includes a receiving platform 6 and a finger sleeve 61 arranged on the receiving platform 6. A accommodating cavity 62 is provided on the hand support plate 11 for the receiving platform 6 to slide up and down. A rotating rod 63 is rotatably connected to the bottom of the receiving platform 6. The rotating rod 63 extends to the outside of the hand support plate 11 and is threadedly connected to the hand support plate 11. Specifically, the material of the finger sleeve 61 is not limited, and a flexible material such as silicone can be used. When the finger is placed inside the finger sleeve 61, the comfort is better. When in use, when the finger is inserted into the finger sleeve 61, the rotating rod 63 is rotated to drive the receiving platform 6 to slide downward in the accommodating cavity 62, and the finger is driven to move downward to contact the upper end surface of the hand support plate 11, thereby avoiding the random flexion and extension of the finger, which causes the needle to deviate.

[0034] Preferably, the lower part of the finger sleeve 61 is connected to the receiving platform 6 by a flexible belt 64. Since the length of the flexible belt 64 is fixed, when the finger is in motion, it can move up and down or left and right within a certain range, thereby reducing the tension and fatigue of the hand muscles and avoiding excessive restriction of the finger by the finger locking member, which may cause finger stiffness or discomfort.

[0035] Preferably, a support cushion 7 is provided at the connection between the hand support plate 11 and the wrist support plate 12. When the patient's hand is placed on the receiving member, the wrist is supported by the support cushion 7, which better conforms to the curve of the wrist, has a certain supporting effect, and improves the patient's comfort.

[0036] Preferably, the locking member includes a first strap 8 and a reserved groove 81 opened on the protective cover 2. The movable end of the first strap 8 is detachably connected to the hand support plate 11 through a connecting member. After the protective cover 2 is installed, the movable end of the first strap 8 is connected to the hand support plate 11 to fix the protective cover 2 on the hand support plate 11. At the same time, the first strap 8 can be located in the reserved groove 81 to prevent the first strap 8 from falling off the protective cover 2.

[0037] Preferably, the locking member also includes a second strap 9, which is connected to the wrist support plate 12, and the movable ends of the second strap 9 are connected via a connector. The second strap 9 can be used to connect the patient's wrist to the wrist support plate 12 to avoid arbitrary bending of the patient's wrist and reduce the occurrence of needle falling off due to hand movements. The connector can be connected and fixed by Velcro or letter buckles.

[0038] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
