Abstract

The utility model discloses a disposable adjustable safety spring needle, which relates to the technical field of medical devices. The utility model includes a safety box, in which two partitions are fixed, and the partitions divide the safety box into three placement areas. A slide plate slides in the placement area, and a spring is fixed between the slide plate and the inner wall of the safety box. A blood glucose needle is detachably arranged on the slide plate, and also includes an adjustment mechanism arranged on the safety box for adjusting the length of the blood glucose needle and a protection mechanism arranged outside the safety box. Through the design of the safety box, the utility model allows the blood glucose needle to be retracted into the safety box after use, thereby avoiding the risk of the blood glucose needle stabbing the medical staff or the patient again. The partition plate and slide plate system in the safety box limit the range of motion of the blood glucose needle, ensuring safe storage and retrieval. Since the blood glucose needle can be completely retracted into the safety box, possible blood contact is avoided, reducing the risk of spreading germs and diseases.

DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

The present application provides a disposable adjustable safety spring needle, which is mainly used to solve the problem that some blood glucose needles cannot be retracted after use, and may stab medical staff or patients again, resulting in safety hazards when using blood glucose needles, and provides the following technical solutions, which will be described in detail in conjunction with Figures 1 to 4:

A disposable adjustable safety spring needle comprises a safety box 1, wherein two partitions 2 are fixed in the safety box 1, the partitions 2 divide the safety box 1 into three placement areas 3, a slide plate 4 is slid in the placement area 3, a spring 5 is fixed between the slide plate 4 and the inner wall of the safety box 1, a blood glucose needle 6 is detachably arranged on the slide plate 4, and further comprises an adjustment mechanism 7 arranged on the safety box 1 for adjusting the length of the blood glucose needle 6 and a protection mechanism 8 arranged outside the safety box 1. In some embodiments: through the design of the safety box 1, the blood glucose needle 6 can be retracted into the safety box 1 after use, so as to avoid the blood glucose needle 6 from stabbing the medical staff or the patient again Risk, the partition 2 and slide plate 4 system in the safety box 1 limits the movement range of the blood glucose needle 6, ensuring safe storage and retrieval. Since the blood glucose needle 6 can be completely retracted into the safety box 1, possible blood contact is avoided, reducing the risk of spreading germs and diseases. The length adjustment mechanism 7 provided on the safety box 1 can adjust the length of the blood glucose needle 6 to adapt to different blood collection requirements, which can improve the adaptability of the blood glucose needle 6 and ensure the accuracy and comfort of the blood collection process. The protection mechanism 8 outside the safety box 1 can provide additional protection for the safety box 1 to prevent the blood glucose needle 6 from accidentally stabbing others or being pierced.

The working principle here is: when the blood glucose needle 6 is needed, the blood glucose needle 6 is fixed on the slide plate 4 of the safety box 1. Through the adjustment mechanism 7, the length of the blood glucose needle 6 can be set according to the needs, and then the slide plate 4 is pushed forward into the corresponding placement area 3 until the needle tip of the blood glucose needle 6 can be properly extended for blood collection; after the blood collection is completed, the medical staff will drive the adjustment mechanism 7 to pull the slide plate 4 backward, and the corresponding spring 5 will push the slide plate 4 and the blood glucose needle 6 back into the safety box 1, completely retract the needle tip, and avoid being exposed again, so as to prevent the needle from accidentally stabbing others or being pierced; the protection mechanism 8 outside the safety box 1 can provide additional protection for the safety box 1 to prevent the blood glucose needle 6 from accidentally stabbing others or being pierced.

As shown in Figures 1, 2, and 3, in some embodiments, a needle seat 9 is fixed to the other end of the slide plate 4, and the blood glucose needle 6 is threadedly connected to the needle seat 9. The working principle here is: when the blood glucose needle 6 needs to be used, the threaded portion of the blood glucose needle 6 is inserted into the needle seat 9 and rotated and fixed. At this time, the blood glucose needle 6 is tightly connected to the needle seat 9; through the adjustment mechanism 7, the length of the blood glucose needle 6 can be adjusted according to needs, which can be achieved by increasing or decreasing the thread insertion depth of the blood glucose needle 6 on the needle seat 9; after the blood collection is completed, the medical staff pulls the slide plate 4 backwards, and the corresponding spring 5 will push the slide plate 4, the needle seat 9 and the blood glucose needle 6 back into the safety box 1, completely retracting the blood glucose needle 6 and avoiding exposure to the outside again, thereby preventing the needle from accidentally stabbing others or being pierced.

As shown in FIG1 and FIG2, in some embodiments, the top of the safety box 1 is marked with a scale 10, and the working principle here is: the scale 10 on the top of the safety box 1 is to facilitate the user to adjust the length of the blood glucose needle 6 as needed. The scale 10 may be marked with a specific length unit, such as millimeters or centimeters.

As shown in FIG. 1 and FIG. 2, in some embodiments, a through hole 11 is provided on the safety box 1 and the blood glucose needle 6 passes through the through hole 11 under the adjustment of the adjustment mechanism 7. The working principle here is that the user changes the length of the blood glucose needle 6 relative to the safety box 1 by operating the adjustment mechanism 7. When the user adjusts the mechanism 7, the blood glucose needle 6 will extend or retract outward or inward in the through hole 11, thereby changing the length of the externally visible part of the blood glucose needle 6.

As shown in Fig. 1, Fig. 2 and Fig. 3, in some embodiments, the adjustment mechanism 7 includes a slide groove 701 constructed on the side of the partition 2 and the inner side of the safety box 1, and the slide plate 4 slides in the slide groove 701. The slide plate 4 is rotatably connected with a screw rod 702, and the other end of the screw rod 702 is threaded through the safety box 1 and fixed with a knob 703. The working principle here is: when the user rotates the knob 703, the screw rod 702 rotates, thereby causing the slide plate 4 to slide in the slide groove 701. By rotating the knob 703 to control the rotation of the screw rod 702, the position of the slide plate 4 can be changed accordingly. Therefore, the length of the blood sugar needle 6 can be adjusted by operating the knob 703.

As shown in FIG. 1 , FIG. 2 , and FIG. 4 , in some embodiments, the protection mechanism 8 includes a protection ring 801 symmetrically fixed to the outside of the safety box 1, and a protection cover 802 is symmetrically mounted on the outside of the safety box 1, and the protection cover 802 abuts against the protection ring 801. The working principle here is: through the design of the protection ring 801 and the protection cover 802, when the blood glucose needle 6 is fully retracted into the safety box 1, the protection cover 802 will abut against the protection ring 801, forming a physical barrier to prevent the blood glucose needle 6 from further extending. This can provide a certain degree of protection to prevent the blood glucose needle 6 from being accidentally overextended or exposed to the outside.

The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
