Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a bendable self-locking infusion hand plate. Background Technology

[0002] Intravenous infusion is a method that uses atmospheric pressure and hydrostatic pressure to deliver large amounts of sterile fluids, electrolytes, and medications into the body through a vein. When children or the elderly receive intravenous infusions, their hands need to be immobilized to prevent them from moving around and causing the needle to puncture the blood vessel.

[0003] Most existing infusion handpieces are straight-plate designs, requiring the user's hand to remain straight during use. Since some existing infusion needles require the user's hand to be bent for smooth infusion, the existing infusion handpieces do not allow for adjustment of the user's hand bending degree, thus affecting usability. Utility Model Content

[0004] The purpose of this invention is to provide a bendable self-locking infusion handpiece to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The screw rod is rotated by the rotating component, so that the push block moves upward under the action of the moving component. The push block lifts the support plate and elastic cloth upward, which makes it easy for the user's hand to bend when placed on the device. The degree of bending is easy to adjust and use, which is convenient for infusion work. At the same time, the use of the fixing component makes it easy to fix the user's hand, preventing the user's hand from moving around during infusion, which could cause the needle to puncture the blood vessel. It is convenient to use.

[0016] (2) By setting up the heating component, it is easy to heat the air inside the fixed frame, and then the fan blows the hot air through the ventilation holes to the user's hand to heat the hand receiving the infusion, so as to avoid the user's hand being cold due to the low temperature of the medicine, and improve the user's comfort during the infusion.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figures 1-5 As shown, a bendable self-locking infusion handpiece includes: a mounting frame 1, an elastic fabric 2 fixedly mounted on the top of the mounting frame 1, a support plate 3 fixedly mounted on the bottom of the elastic fabric 2, a push block 4 below the support plate 3, the top of the push block 4 being arc-shaped, a moving component connected to the bottom of the push block 4, an adjustment mechanism for adjusting the push block 4 to move up and down inside the mounting frame 1, and a fixing component and a heating component respectively mounted on the mounting frame 1;

[0026] The adjustment mechanism includes a first fixed plate 5 fixedly installed in the mounting frame 1. A threaded rod 6 is rotatably installed through the first fixed plate 5. A threaded groove adapted to the threaded rod 6 is opened on the push block 4. The push block 4 and the threaded rod 6 are threadedly connected. A rotating component for adjusting the rotation of the threaded rod 6 is provided in the mounting frame 1.

[0027] As can be seen from the above, the user places their hand on the elastic fabric 2, and the fixing component secures the user's hand. The rotating component drives the threaded rod 6 to rotate, causing the push block 4 to move upward under the drive of the threaded rod 6. During the upward movement, the push block 4 lifts the support plate 3 and the elastic fabric 2, thereby causing the user's hand to bend, making it easier for the user to grip the device. The higher the push block 4 moves, the greater the degree of hand bending, and vice versa. The degree of bending is easy to adjust and convenient to use.

[0028] Specifically, regarding the aforementioned rotating assembly, please refer to... Figure 2 and Figure 3 As shown, the rotating assembly includes a second fixed plate 7 fixedly installed inside the mounting frame 1. A rotating rod 8 is rotatably installed through the second fixed plate 7. A bevel gear 9 is fixedly installed at the end of the rotating rod 8 and the bottom of the threaded rod 6. The two bevel gears 9 are meshed and connected. The end of the rotating rod 8 away from the bevel gear 9 is rotatably installed on the inner side wall of the mounting frame 1.

[0029] An adjustment knob 10 is rotatably mounted on the outer wall of the mounting frame 1. A worm gear 11 is fixedly mounted on the adjustment knob 10. The end of the worm gear 11 away from the adjustment knob 10 is rotatably mounted on the inner wall of the mounting frame 1. A worm wheel 12 is fixedly sleeved on the rotating rod 8. The worm gear 11 and the worm wheel 12 are meshed together.

[0030] As can be seen from the above, by rotating the adjustment knob 10 clockwise, the adjustment knob 10 drives the worm gear 11 to rotate. The worm gear 11 drives the rotating rod 8 to rotate through the worm wheel 12, which in turn drives the threaded rod 6 to rotate through the bevel gear 9. This causes the push block 4 to move upward, lifting the support plate 3 and the elastic fabric 2, making the support plate 3 and the elastic fabric 2 protrude, making it easier for the user to bend and grip. After adjusting to the appropriate position, stop rotating the adjustment knob 10. Due to the self-locking property between the worm wheel 12 and the worm gear 11, after bending and adjusting, the pressure of the hand pressing on the elastic fabric 2 will not cause the push block 4 to move downward, thus maintaining the adjusted shape and making it easy to use. After use, by rotating the adjustment knob 10 counterclockwise, the push block 4 moves downward to complete the reset. For details regarding the above-mentioned moving components, please refer to... Figure 2 As shown, the movable component includes multiple guide rods 13 fixedly installed on the bottom of the mounting frame 1. Each guide rod 13 has a limit block fixedly installed on its top. A movable plate 14 is slidably installed on the multiple guide rods 13. The top of the movable plate 14 is fixedly connected to the bottom of the push block 4. The movable plate 14 has an opening that is compatible with the threaded rod 6.

[0031] As can be seen from the above, the cooperation between the guide rod 13 and the moving plate 14 facilitates the push block 4 to move up and down along the guide rod 13, making the push block 4 more stable during the movement.

[0032] Specifically, regarding the aforementioned fixing components, please refer to... Figure 1 As shown, the fixing component includes a mounting base 15 fixedly mounted on the mounting frame 1. A soft pad 16 is fixedly mounted on the top of the mounting base 15. A first fixing strap 17 and a second fixing strap 18 are fixedly mounted on the mounting base 15 and the elastic fabric 2, respectively. A sponge pad 19 is fixedly mounted on the bottom of both the first fixing strap 17 and the second fixing strap 18.

[0033] As can be seen from the above, the first fixing strap 17 and the second fixing strap 18 are elastic straps. The first fixing strap 17 fixes the user's wrist, and the second fixing strap 18 fixes the user's fingers. The mounting base 15 and the soft pad 16 support the user's wrist. The sponge pad 19 prevents the first fixing strap 17 and the second fixing strap 18 from excessively squeezing the user's hand during use, thus improving the comfort during use.

[0034] Preferably, the support plate 3 is made of sponge, rubber or shape memory polymer, so that the support plate 3 can be restored to its original shape after use.

[0035] As can be seen from the above, when the push block 4 moves downward, the support plate 3 can be reset by its own characteristics or by the elastic cloth 2, making it convenient for the next use.

[0036] Example 2:

[0037] refer to Figure 1 , Figure 2 and Figure 4 As shown, the heating assembly includes a fixed frame 20 that runs through and is fixedly mounted on the mounting frame 1. A heating device 21 and a fan 22 are fixedly mounted inside the fixed frame 20. Multiple ventilation holes 23 are provided on both the elastic fabric 2 and the support plate 3.

[0038] As can be seen from the above, both the heating device 21 and the fan 22 are existing technologies and will not be described in detail here. After the heating device 21 heats the air to a comfortable temperature range for the human body, the fan 22 blows hot air through the ventilation hole 23 to the user's hands to heat the user's hands and prevent the user's hands from getting cold due to the low temperature of the medicine, thereby improving the user's comfort during infusion.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
