Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of infusion sets, in particular to a protective anti-drag infusion set. Background Art
[0002] An infusion set, also known as an infusion pump, is a medical device used for infusion. Traditionally, the infusion method involves suspending liquid in a bottle or bag high above the ground, allowing gravity to force the liquid through a tubing into a vein. The flow rate is manually adjusted using a clamp attached to the tubing, based on the drip rate in the dropper.
[0003] When using current infusion sets, medical staff may not insert the puncture needle tightly. When the patient stands up and moves around during the infusion, the infusion set may be pulled, which may tear off the puncture needle, causing contamination of the puncture needle and making it unusable.

[0012] In a preferred embodiment of the present invention, a pulling block is provided outside the limiting block.
[0013] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention.
[0014] Beneficial effect: When the infusion pump is in use, the limit block is pulled by the pulling block to remove the limit block. When the infusion bottle is inserted through the puncture, the clamping ring will be pushed into the annular groove, and the limit bar will be limited by the limit rail, so that the clamping ring keeps moving vertically, and the limit bar on the top of the clamp has a limiting effect on the clamping ring.

[0022] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0023] Please refer to Figure 1-4 The utility model provides a protective anti-drag infusion set, including an infusion set body 1. The top of the infusion set body 1 includes a puncture 11. The infusion set body 1 is the main body of the infusion set, which is mainly used to connect the structure on one side of the infusion bottle. The puncture 11 is the main structure, which is used to insert the infusion bottle. The bottom of the infusion set body 1 includes an infusion tube 14, which is used to infuse the patient. One side of the infusion set body 1 is provided with an air inlet connector 12, and the air inlet connector 12 includes a cap 13. The inside of the puncture 11 includes an infusion channel 2. The air inlet connector 12, the cap 13, and the infusion channel 2 are all the main structures on the infusion set, that is, to ensure that the infusion set can be infused. A through-hole 21 is provided on one side above the puncture 11, and the through-hole 21 is connected to the inside of the infusion channel 2, so that when the liquid level in the infusion bottle reaches the bottom, it is convenient to infuse the liquid.
[0024] When the puncture point 11 is inserted into the infusion bottle, the bottom of the card 33 is pushed by the spring 4 and moves on the movable plug 31 through the movable opening 34, so that the bottom of the card 33 is pushed out, that is, it is stuck in the inside of the infusion bottle, thereby preventing it from being pulled off.
[0025] A snap ring 42 is provided on the outside of the clamp 33, and the snap ring 42 slides on the outside of the puncture 11. An annular groove 22 is provided on the outside of the bottom of the puncture 11. A limiting block 44 is provided on the bottom of one side of the snap ring 42, and a limiting opening 24 is provided on one side of the bottom of the puncture 11. The limiting block 44 is slidably connected to the limiting opening 24. A limiting rail 23 is provided on the outer bottom of the installation groove 3 and the outer bottom of the clamp 33. Limiting strips 43 are provided on both sides of the inside of the snap ring 42. The limiting strips 43 are slidably connected to the limiting rails 23, that is, the limiting strips 43 are limited by the limiting rails 23, so that the snap ring 42 is kept in place. It maintains vertical movement, and the limit bar 43 on the top of the card 33 has a limiting effect on the clamping ring 42. A pulling block 45 is provided on the outside of the limit block 44. The pulling block 45 is used to pull or push the limit block 44 for easy removal. When the infusion set is not in use, it is installed on the outside of the card 33 through the clamping ring 42 to prevent the card 33 from popping out, and the limit block 44 is connected to the limit port 24, so that the limit port 24 fixes the bottom of the clamping ring 42. When in use, the limit block 44 is taken out, and when the puncture 11 is inserted, the clamping ring 42 is pushed into the annular groove 22.
[0026] The working principle of the present utility model is as follows: when the infusion set is not in use, the clamping ring 42 is installed on the outside of the clamping piece 33 to prevent the clamping piece 33 from popping out, and the limiting opening 24 is connected to the limiting block 44, so that the limiting opening 24 fixes the bottom of the clamping ring 42. When the infusion set is in use, the limiting block 44 is pulled by the pulling block 45 to remove the limiting block 44. When the puncture 11 is inserted into the infusion bottle, the clamping ring 42 will be pushed into the annular groove 22, and the limiting bar 43 will be limited by the limiting rail 23, so that the clamping ring 42 keeps moving vertically, and the limiting bar 43 at the top of the clamping piece 33 has a limiting effect on the clamping ring 42. When the puncture 11 is inserted into the infusion bottle, the bottom of the clamping piece 33 is pushed by the spring 4, and moves on the movable plug 31 through the movable opening 34, so that the bottom of the clamping piece 33 is pushed out, that is, it is stuck on the inside of the infusion bottle, thereby preventing it from being pulled off.
