Description

Technical Field

[0001] This utility model relates to the technical field of residual needle protection devices, specifically a residual needle protective cover. Background Technology

[0002] An indwelling needle is a reusable needle inserted into a blood vessel once for long-term intravenous infusions. It can reduce the pain of multiple injections for patients, especially those with edema. For infants, a special group, the length of time the indwelling needle remains in place and the child's comfort are the primary concerns for nurses and parents. Therefore, the protection of the indwelling needle is crucial. However, traditional indwelling needle protection devices do not consider the impact of low temperatures on the injection site in infants' hands during winter. Infants have weaker resistance and are more sensitive than adults; poor comfort can cause them to move around and cry, affecting intravenous treatment. Therefore, the lack of a heating device in the indwelling needle protection equipment hinders the improvement of infants' comfort in winter and affects intravenous treatment.

[0003] The existing drawbacks of the indwelling needle protection device are:

[0004] 1. Patent document CN217510931U discloses an indwelling needle protective sleeve, including an adhesive patch and a sleeve worn on the arm. The sleeve body has an observation port, and a closure is sewn to the side of the observation port. Velcro fasteners are provided at the edges of both the observation port and the closure. An adhesive patch, partially overlapping the closure, is attached to the side of the observation port. The adhesive patch is protected inside the sleeve to avoid the influence of external moisture, ensuring the adhesiveness of the tape and effectively preventing the indwelling needle from detaching. The observation port is sealed by the closure. When the indwelling needle is needed for intravenous infusion, the observation port is opened to connect the infusion tubing to the indwelling needle without removing the protective sleeve. Simultaneously, the puncture wound can be observed at any time. By using adhesive strips, not only is the indwelling needle fixed to the arm, but the sleeve is also fixed to prevent the sleeve from moving and effectively prevent the indwelling needle from falling out. Compared with this utility model, the indwelling needle protective sleeve in the disclosed patent lacks a heating structure and does not consider the impact of low temperature on the injection site of the indwelling needle in the infant's hand when used in winter. Infants have weaker resistance and are more sensitive than adults. Poor comfort can cause infants to move around and cry, affecting the IV drip treatment. Therefore, the lack of a heating device for the indwelling needle protection device is not conducive to improving the infant's comfort when using it in winter and affects the IV drip treatment. Utility Model Content

[0005] The purpose of this invention is to provide a protective cover for a retained needle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a retaining needle protective cover, comprising a protective cover body, a cover plate and a first elastic strap, wherein the cover plate is movably mounted on the top of the protective cover body via a pivot, and the first elastic strap is mounted on the back of the protective cover body;

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

[0015] 1. This utility model features a movable fixing plate installed on one inner wall of the protective cover body. A spring is installed at the bottom of the movable fixing plate, and one end of the spring is connected to one inner wall of the protective cover body. A heating box is installed on the top of the movable fixing plate. When an infant wears a protective cover for an indwelling needle in winter, the low temperature may cause discomfort to the infant's injection site. This new invention utilizes a heating box containing iron powder, activated carbon, water, and a catalyst. When the cover is opened and air enters, an oxidation reaction occurs, generating heat to heat the injection site on the infant's hand. This avoids the impact of low temperature on the needle hole injection site when the infant uses the indwelling needle, improves the comfort of the infant's hand, and prevents the infant from being restless or crying, which may affect the intravenous drip treatment.

A second elastic strap is symmetrically installed on the front of the protective cover body, with a second lint-adhesive layer at the bottom and an elastic Velcro closure at the bottom. When an infant uses this indwelling needle protective cover, the protective cover body can cover the indwelling needle. The elastic Velcro closure can be used to adjust the tightness of the first and second elastic straps according to the thickness of the infant's arm. Pulling the elastic Velcro closure will then bond the adhesive layer of the Velcro closure to the first and second lint-adhesive layers. Ultimately, the cooperation of the first and second elastic straps with the Velcro closure makes securing the indwelling needle protective cover easier. Medical personnel can also insert the infusion tube into the inside of the protective cover body through the through-hole, open the cover, and connect the indwelling needle. This allows for simultaneous use of the protective cover and infusion, providing protection while simultaneously completing the infant's infusion process, thus improving the convenience of using the indwelling needle protective cover.

[0029] Please see Figure 1 , Figure 4 , Figure 5 and Figure 6 One embodiment of this utility model is a retaining needle protective cover;

[0030] The protective cover body 1 includes a second elastic strap 4, elastic Velcro 5, and a movable fixing plate 6. The second elastic strap 4 is symmetrically installed on the front of the main body 1. A fixing screw 401 is installed on the front of the second elastic strap 4. A second lint-adhesive layer 402 is provided at the bottom of the second elastic strap 4. Elastic Velcro 5 is installed at the bottom of the second elastic strap 4, and a fixing member 501 is installed through the bottom of the elastic Velcro 5. A movable fixing plate 6 is installed on one inner wall of the main body 1, and a spring 60 is installed at the bottom of the movable fixing plate 6. 1. One end of the spring 601 is connected to the inner wall of one side of the protective cover body 1. A heating box 602 is installed on the top of the movable fixing plate 6. An upper fixing plate 603 is installed on the inner wall of one side of the protective cover body 1, and the bottom of the upper fixing plate 603 is in contact with the top of the heating box 602. The heating box 602 contains chemical heating powder 604, and a non-woven breathable membrane 605 is provided on the inner wall of one side of the heating box 602. The second elastic strap 4 and the first elastic strap 3 together complete the fixation of the protective cover body 1.

The upper fixing plate 603 and the movable fixing plate 6 together fix the heating box 602. The chemical heating powder 604 contains iron powder, activated carbon, water and catalyst. It can generate heat by oxidation reaction. The non-woven breathable membrane 605 allows air to enter slowly, and the oxidation reaction will not occur too quickly, so that the temperature rises steadily.

[0031] Working principle: When using the indwelling needle protector on an infant's hand, medical staff can cover the indwelling needle with the main body 1 of the protector, while the outer rubber pad 101 provides a seal. Then, using elastic Velcro 5, the tightness of the first elastic band 3 and the second elastic band 4 is adjusted according to the thickness of the infant's arm. Pulling the elastic Velcro 5 then bonds the adhesive layer of the elastic Velcro 5 to the first lint-adhesive layer 302 and the second lint-adhesive layer 402. Finally, the cooperation of the first elastic band 3, the second elastic band 4, and the elastic Velcro 5 makes the indwelling needle protector more securely fixed. In this way, medical staff can also insert the infusion tube into the inside of the protective cover body 1 through the through hole 104, open the cover plate 2, and connect the indwelling needle. In this way, the infusion can be performed while the protective cover is worn, thus completing the infusion work for the baby at the same time. When the baby wears the indwelling needle protective cover in winter, the low temperature may cause discomfort to the baby's injection site. This new type of heating box 602, which contains iron powder, activated carbon, water and catalyst, generates heat through an oxidation reaction after the air enters when the cover plate 2 is opened. This heats the injection site on the baby's hand, improving the comfort of the baby's hand.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
