[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example, reference Figures 1 to 5 .

[0029] A device for preventing needle loss for nursing, comprising a first restraint belt 1, a second restraint belt 2, a needle pressing belt 3, a telescopic box 4, a telescopic plate 5, a Velcro 6, an adjuster 7 and a handle 8. An opening 9 is provided on one side of the telescopic box 4, and the telescopic plate 5 is slidably installed in the opening 9. Movable grooves 10 are symmetrically provided on both sides of the telescopic box 4, and the movable grooves 10 are perpendicular to and connected with the openings 9. One end of the first restraint belt 1 is fixedly installed on the same side wall of the telescopic box 4 as the movable groove 10 by a buckle, and the adjuster 7 is installed on the side wall of the telescopic box 4 corresponding to the first restraint belt 1 by a bolt. The first restraint belt 1 passes through the adjuster 7, and the adjuster 7 adjusts the length of the first restraint belt 1 by folding the first restraint belt 1. The remaining restraints have the same functions and will not be described in detail later.

[0030] One end of the second restraint belt 2 is installed on the side wall of the telescopic plate 5 close to the movable groove 10, and the adjuster 7 is installed on the side wall of the telescopic plate 5 corresponding to the second restraint belt 2. The adjuster 7 and the second restraint belt 2 are both located outside the telescopic box 4. The second restraint belt 2 passes through the adjuster 7, and the second restraint belt 2 can move with the telescopic plate 5.

[0031] One end of the needle pressing belt 3 is installed on the side wall of the telescopic plate 5 close to the movable groove 10, and the adjuster 7 is installed on the side wall of the telescopic plate 5 corresponding to the needle pressing belt 3. The adjuster 7 and the needle pressing belt 3 are both located on the outside of the telescopic box 4. The needle pressing belt 3 passes through the adjuster 7. The needle pressing belt 3 is located between the first constraint belt 1 and the second constraint belt 2. The needle pressing belt 3 is used to press and fix the needle tip to avoid accidental touch.

[0032] The first restraint strap 1, the second restraint strap 2, and the needle pressure strap 3 are each fitted with Velcro 6. When the first restraint strap 1, the second restraint strap 2, and the needle pressure strap 3 are folded through the adjuster 7, the folded portions are secured by the Velcro 6, allowing the first restraint strap 1, the second restraint strap 2, and the needle pressure strap 3 to secure the patient's hand, the infusion tube, and the needle. A handle 8 is mounted on the end of the telescopic plate 5 away from the inner bottom wall of the telescopic box 4. The handle 8 facilitates adjustment of the telescopic plate 5 by medical personnel.

[0033] The working surfaces of the telescopic box 4 and telescopic plate 5 that contact the patient's hand are covered with a layer of soft material 15. This reduces the pressure between the hand and the telescopic box 4 and telescopic plate 5 under the compression of the first and second restraining straps 1, thereby improving the comfort of the nursing needle removal prevention device. The soft material 15 can be made of rubber, latex, sponge, etc.

[0034] An arc-shaped flange 11 is provided on the edge of the opening 9 , with the center of the flange 11 facing the side close to the telescopic plate 5 . The flange 11 is used to prevent the patient's hand from being stuck in the gap between the telescopic plate 5 and the telescopic box 4 when adjusting the telescopic plate 5 .

[0035] The telescopic plate 5 is provided with a chute 12 on both sides near the movable groove 10. The second restraint belt 2, the needle pressing belt 3 and the corresponding adjuster 7 are slidably installed in the chute 12, so that the needle pressing belt 3 and the second restraint belt 2 can be independently adjusted on the basis of the telescopic plate 5, thereby improving the practicality of the anti-needle-drop device for nursing. When the needle pressing belt 3 and the second restraint belt 2 are tightened by the Velcro 6, static friction will be generated between the needle pressing belt 3 and the second restraint belt 2 and the patient's hand, thereby fixing the needle pressing belt 3 and the second restraint belt 2 and preventing them from moving along the chute 12. Therefore, the needle pressing belt 3 and the second restraint belt 2 do not require a fixing device.

[0036] The telescopic plate 5 and the telescopic box 4 are interference fit, so there is a large static friction and dynamic friction between the two. The dynamic friction causes a certain resistance when the telescopic plate 5 and the telescopic box 4 move relative to each other, and the static friction prevents the two from having any relative displacement.

[0037] Gaps are provided between the working surface of the telescopic plate 5 that contacts the patient's hand and the inner wall of the telescopic box 4, as well as the opposite surface. The telescopic plate 5 is hollow, and corresponding ventilation holes 13 are provided on the telescopic box 4, the telescopic plate 5, and the soft material 15. Therefore, even if the ventilation holes on the telescopic plate 5, the telescopic box 4, and the soft material 15 do not correspond to each other, air circulation can still be achieved. During prolonged intravenous treatment, the telescopic plate 5 and the telescopic box 4 are pressed against the skin, causing discomfort to the patient.

[0038] It also includes a tube press 14, which includes an arc portion and support portions at both ends of the arc portion. The tube press 14 is a hollow structure with through holes at both ends. The tube press 14 is slidably installed on the second restraint belt 2 through the through holes. The side of the arc portion close to the telescopic plate 5 is covered with rubber for increasing friction. The tube press 14 can be moved and adjusted arbitrarily on the second restraint belt 2. The support portion will fit the patient's hand to avoid excessive deformation of the arc portion. The diameter of the arc portion is smaller than the diameter of the infusion tube, so there will be a certain amount of squeezing between the tube press 14 and the infusion tube. Since the side of the arc portion close to the telescopic plate 5 is covered with rubber for increasing friction, the applied pressure cooperates with the rubber to fix the infusion tube, preventing the needle from falling off due to the infusion tube being accidentally touched and pulled.

[0039] The foregoing descriptions of specific exemplary embodiments of the present invention are for the purpose of illustration and description. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials or characteristics described can be combined in an appropriate manner in any one or more embodiments or examples. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can make modifications, substitutions, variations and various different choices and changes to the embodiments without creative contribution as needed after reading this specification without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
