Abstract
Description
Technical Field
[0001] This utility model specifically relates to a pull-up type anti-sharp-insect lock infusion set. Background Technology
[0002] According to incomplete statistics, healthcare workers worldwide experience a relatively high incidence of sharps injuries during their careers. Sharps injuries not only increase the risk of healthcare workers contracting bloodborne diseases, but also cause negative psychological emotions such as fear, anxiety, and depression, posing a significant threat to their occupational safety and mental and physical health.
[0003] The existing infusion set requires the use of scissors or other auxiliary tools to destroy the bottle stopper after the infusion is completed, which greatly increases the risk of occupational exposure for medical staff, and also increases the time nurses spend handling medical waste, reducing work efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a pull-up type anti-sharp-insertion lock infusion set to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a pull-up type anti-sharp-insect locking infusion set, comprising an infusion tube, a bottle stopper puncturist, and a locking assembly. One end of the infusion tube is connected to the recipient, the bottle stopper puncturist is disposed at the other end of the infusion tube, and the locking assembly is disposed on the infusion tube. By pulling the locking assembly, the locking assembly fixes the bottle stopper puncturist, ensuring that the tip of the bottle stopper puncturist is not exposed.
[0006] Preferably, the locking assembly includes a locking sleeve fitted onto the infusion tube, wherein an independent cavity is formed within the locking sleeve for covering the bottle stopper puncture device.
[0007] Preferably, the bottle stopper puncturer has outwardly extending abutment portions on both sides of its tail, and the abutment portions have a triangular cross-section.
[0008] Preferably, a groove is provided along the length of the inner wall of the cartridge for the sliding of the abutment portion.
[0009] Preferably, a locking slide is provided around the inner wall of the cylinder to match the abutment portion.
[0010] Preferably, the infusion tube is also equipped with a flow regulator and a drip chamber, and the retainer is positioned between the drip chamber and the bottle stopper puncture device.
[0011] The technical effects and advantages of this utility model are as follows: After the infusion is completed, simply pull, rotate the locking cylinder, or pull back the upper part of the infusion tube. The locking cylinder will move along the maximum diameter of the sliding groove inside the independent cavity of the bottle stopper puncture device, thus moving to the locking point. Rotating the locking cylinder will cause the abutment parts on both sides of the bottle stopper puncture device to be misaligned from the sliding groove, thereby sliding into the locking slide, fixing the bottle stopper puncture device in the independent area. The bottle stopper puncture device can then be properly locked at the locking point and can no longer move up or down, thus ensuring that the tip of the bottle stopper puncture device is not exposed.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0015] To ensure that the tip of the bottle stopper puncturer 2 does not protrude, refer to... Figure 1 , Figure 2 and Figure 3 As shown, the device includes an infusion tubing 1, a bottle stopper puncturist 2, and a locking assembly. One end of the infusion tubing 1 is connected to the recipient, and the bottle stopper puncturist 2 is located at the other end of the infusion tubing 1. The locking assembly is located on the infusion tubing 1. By lifting the locking assembly, the bottle stopper puncturist 2 is fixed in place, ensuring that the tip of the bottle stopper puncturist 2 is not exposed. After the infusion is completed, simply lift and rotate the locking cylinder 3 or pull back the upper part of the infusion tubing 1. The locking cylinder 3 will then move along the maximum diameter of the sliding groove 5 inside the independent cavity of the bottle stopper puncturist 2, thus moving to the locking point. Rotating the locking cylinder 3 will cause the abutment parts 4 on both sides of the bottle stopper puncturist 2 to be displaced from the sliding groove 5, thereby sliding into the locking slide 6 to fix the bottle stopper puncturist 2 in the independent area. The bottle stopper puncturist 2 will then be properly locked in the locking point and will no longer be able to move up or down, thus ensuring that the tip of the bottle stopper puncturist 2 is not exposed.
[0016] To reduce the cost of treating hazardous medical waste, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the locking assembly includes a locking sleeve 3 sleeved on the infusion tube 1. The locking sleeve 3 forms an independent cavity for enclosing the bottle stopper puncture device 2. The bottle stopper puncture device 2 is housed within this independent cavity, preventing its tip from protruding. This design is convenient, time-efficient, and allows for a smooth, one-step operation, effectively avoiding occupational exposure risks for medical personnel and solving the practical problems of heavy and cumbersome clinical medical waste disposal for nurses. Both sides of the tail of the bottle stopper puncture device 2 are provided with outwardly extending abutment portions 4. These abutment portions 4 have a triangular cross-section and are inserted into a sliding groove 5. By sliding along the length of the groove 5, the locking sleeve 3 can be moved to the outside of the bottle stopper puncture device 2. A groove 5 is provided along the length of the inner wall of the clamping cylinder 3 for the sliding of the abutment part 4. A locking slide 6, adapted to the abutment part 4, is provided around the inner wall of the clamping cylinder 3. The bottle stopper puncturist 2 enters the clamping cylinder 3 through the groove 5. As the clamping cylinder 3 is rotated, the abutment parts 4 on both sides of the bottle stopper puncturist 2 rotate into the locking slide 6, thereby completing the fixation of the bottle stopper puncturist 2. It is applicable to common infusion set types on the market. The bottle stopper puncturist 2 is made of steel needles, plastic needles, and plastic-steel needles. The device is transparent, compact, and aesthetically pleasing, and does not affect the patient's or medical staff's observation during the infusion process. It can significantly reduce the risk of medical staff contracting blood-borne diseases, thereby ensuring their occupational safety. At the same time, it greatly reduces the pain and economic losses caused by blood tracking and testing, injection of blocking drugs, etc. due to sharp instrument injuries. The infusion tube 1 is also equipped with a flow regulator 7 and a drip chamber 8. The clamping cylinder 3 is located between the drip chamber 8 and the bottle stopper puncturist 2. The destructible infusion set will simplify the complex procedures nurses go through in handling medical waste, reduce time consumption, improve work efficiency, save labor costs, thereby improving the hospital's economic benefits, saving space in sharps containers, and reducing the cost of handling sharps waste.
[0017] When in use, after the infusion is finished, simply pull up or rotate the clamp 3 or pull back the upper part of the infusion tube 1. The clamp 3 will move along the sliding groove 5 corresponding to the maximum diameter of the independent cavity inside the bottle stopper puncture device 2. Then, rotate the clamp 3 to make the abutment parts 4 on both sides of the bottle stopper puncture device 2 displace from the sliding groove 5 and slide into the locking slide 6. This will fix the bottle stopper puncture device 2 in the independent area, and the bottle stopper puncture device 2 will be properly locked at the locking point and will no longer be able to move up or down.
[0018] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
