Description

Technical Field

[0001] This invention relates to the field of indwelling needle technology, and in particular to an indwelling needle protection device with a call button. Background Technology

[0002] An indwelling needle, also known as an indwelling venous catheter, is a soft catheter inserted into a vein for short-term (usually 3-7 days) intravenous infusion or drug administration. The design of indwelling needles in clinical applications can reduce the number of punctures, improve patient comfort, and lower the incidence of complications, significantly improving medical efficiency and patient experience.

[0003] Research and observation revealed certain shortcomings in the practical application of indwelling catheters. The fixation method for indwelling catheters is relatively simple, making them prone to dislodgement or displacement if the patient frequently moves their limbs. Furthermore, the lack of a call device means that in case of an emergency or when the patient is temporarily unable to move their limbs significantly, the bedside call system and voice calls are not very effective.

[0004] Therefore, in order to solve the problems existing indwelling needles, this invention proposes an indwelling needle protection device with a call button. Summary of the Invention

[0005] The purpose of this invention is to provide an indwelling needle protection device with a call button, which effectively protects the indwelling needle tip, reduces the pain caused by the needle tip bumping during the patient's activity during hospitalization, reduces the risk of accidents such as needle tip dislodgement and movement, and at the same time ensures that the patient can call medical staff in case of emergency or when the limb is temporarily unable to move significantly, so as to detect and resolve abnormal situations as early as possible.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A protective device for an indwelling needle with a call button includes: a protective cover, characterized in that one end of the protective cover is provided with an elliptical air hole, and the other end is widened and provided with a hollow, upward-opening reserved groove, the reserved groove is sealed by a groove cover, a call button is fixed in the reserved groove, the top of the protective cover is a transparent top plate with a circular ventilation hole, the bottom of the protective cover is provided with an anti-slip sponge pad, and both ends of the protective cover are provided with handles, elastic bands are tied to the handles, and Velcro is fixed to the ends of the elastic bands.

[0008] Furthermore, one end of the protective cover is provided with multiple elliptical air holes, and the transparent top plate is provided with multiple circular ventilation holes. The elliptical air holes and the circular ventilation holes are of different sizes, and the elliptical air holes are larger.

[0009] Furthermore, the protective cover has handles at both ends, and there is no elliptical air hole at the point where the elliptical air hole connects with the handle.

[0010] Furthermore, the pager is fixed in a reserved slot in the protective cover. A wireless transmitter, a circuit board, a button battery, a call button, and an indicator light are fixed in the reserved slot in sequence and electrically connected. The wireless transmitter, circuit board, and button battery are located in the reserved slot, while the call button and indicator light are located outside the reserved slot. The reserved slot has a slot cover with an upward opening.

[0011] Furthermore, the hook side of the elastic band on one side of the elliptical air hole is fixed to the elastic band end, and the rough side of the elastic band on one side of the pager is fixed to the elastic band end.

[0012] Compared with the prior art, the present invention provides an indwelling needle protection device with a call button, which has the following advantages:

[0013] The present invention proposes an indwelling needle protection device with a call button. Its protective cover can protect the needle from being bumped or knocked during the patient's posture adjustment or turning over, thereby reducing the pain caused by the needle squeezing the blood vessel and improving the patient's quality of life in the hospital.

[0014] This invention proposes an indwelling needle protection device with a call button. The call button is worn on the arm along with the protection device. When the patient experiences discomfort at the indwelling needle site, the status of the indwelling needle can be immediately observed through the transparent top plate, and the call button can be pressed immediately. Alternatively, when the patient is in an emergency and cannot significantly adjust their position, making it impossible to press the call bell by the bedside, the call button can play a crucial role in promptly notifying medical staff to detect and resolve the abnormality.
