Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary devices, specifically an improved infusion set. Background Technology

[0002] Infusion sets are common medical consumables. After sterilization, they establish a channel between the vein and the medication for intravenous infusion. They are generally composed of eight parts: an intravenous needle or injection needle, a needle cap, an infusion tube, a medication filter, a flow regulator, a drip chamber, a stopper puncture device, and an air filter. Some infusion sets also have injection parts and medication inlets. Currently, steel needles have many problems in use: patients are inconvenient to move during infusion, and if they use their mobile phones while receiving infusion, there is a risk of drug extravasation. Elderly people have more fragile blood vessels, and the needle tip can still easily rupture blood vessels and cause drug extravasation during infusion. Needlestick injuries can also occur due to various external factors during puncture and needle removal. Utility Model Content

[0003] The purpose of this invention is to provide an improved infusion set to solve the problems mentioned in the background art regarding the current use of steel needles: patients are inconvenient to move during infusion, and if they play on their mobile phones while receiving infusion, the drugs may leak out; the blood vessels of the elderly are more fragile, and the needle tip may still easily rupture the blood vessels and leak drugs out during infusion; and there are needlestick injuries caused by various external factors during puncture and needle removal.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an improved infusion set, comprising an infusion tubing, an infusion assembly, and a storage assembly;

[0005] Wherein: one end of the infusion tube is connected to a puncture device, and the surface of the infusion tube is provided with a drip chamber;

[0006] The infusion assembly includes a tubing connected to the other end of an infusion tube, an infusion needle on the surface of the tubing, the infusion needle sliding on the surface of the tubing, the inner end of the infusion needle having a tapered tightening structure, and the end of the infusion needle being connected to a needle wing.

[0007] The storage assembly includes a storage box connected to the other end of the infusion tube. The storage box has a storage cavity inside and a strip groove on the top. The infusion needle is stored inside the storage cavity, and the needle wing is inserted inside the strip groove.

[0008] As a preferred embodiment of this utility model: a fixing sleeve is installed on the outside of the storage box, a support rod is inserted and connected inside the fixing sleeve, and a spring is sleeved on the surface of the support rod.

[0009] As a preferred embodiment of this utility model: one end of the support rod is connected to a fixed ball, the outer wall of the infusion needle is provided with a groove, the fixed ball is inserted into the groove, and the other end of the support rod is connected to a handle.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1-4 An improved infusion set includes: an infusion tube 1, an infusion assembly 4, and a storage assembly 5; one end of the infusion tube 1 is connected to a puncture device 2, and a drip chamber 3 is provided on the surface of the infusion tube 1;

[0023] Please see Figure 1 , Figure 3 The infusion assembly 4 includes a tubing 41 connected to the other end of the infusion tube 1. An infusion needle 42 is provided on the surface of the tubing 41. The infusion needle 42 slides on the surface of the tubing 41. The tail end of the infusion needle 42 has a tapered tightening structure inside. A needle wing 43 is connected to the tail end of the infusion needle 42.

[0024] In practical use: A tubing 41 is connected to the other end of the infusion tube 1. An infusion needle 42 is slidably fitted on the surface of the tubing 41. A needle wing 43 is connected to the tail end of the infusion needle 42. During puncture, the infusion needle 42 is punctured into the blood vessel. At this time, the tubing 41 also enters the blood vessel. By pulling the needle wing 43, the infusion needle 42 moves on the surface of the tubing 41 and withdraws from the blood vessel, leaving the tubing 41 in the blood vessel. This infusion method replaces leaving the steel needle inside the blood vessel, which can reduce drug extravasation, facilitate the patient's hand movement, and avoid puncturing the blood vessel. The tapered tightening structure inside the tail end of the infusion needle 42 prevents the infusion needle 42 from detaching from the tubing 41.

[0025] Please see Figure 1 , Figure 4 The storage component 5 includes a storage box 51 connected to the other end of the infusion tube 1. The storage box 51 has a storage cavity 52 inside and a strip groove 53 on the top of the storage box 51. The infusion needle 42 is stored inside the storage cavity 52 and the needle wing 43 is inserted inside the strip groove 53.

[0026] In practical use: The other end of the infusion tube 1 is connected to a storage box 51. The storage box 51 has a storage cavity 52 inside. When the infusion needle 42 is withdrawn from the blood vessel, the needle wing 43 slides inside the strip groove 53, which causes the infusion needle 42 to be stored in the storage cavity 52, thus preventing the infusion needle 42 from being exposed to the outside and causing puncture injuries to personnel. The storage box 51 plays the role of collecting and protecting the infusion needle 42.

[0027] Please see Figure 3 , Figure 4 The storage box 51 is fitted with a fixing sleeve 6 on the outside. A support rod 7 is inserted inside the fixing sleeve 6. A spring 8 is fitted on the surface of the support rod 7. A fixing ball 9 is connected to one end of the support rod 7. A groove 10 is opened on the outer wall of the infusion needle 42. The fixing ball 9 is inserted inside the groove 10. A handle 11 is connected to the other end of the support rod 7.

[0028] In practical use: A fixing sleeve 6 is installed on the outside of the storage box 51. A support rod 7 is slidably inserted inside the fixing sleeve 6. A spring 8 is sleeved on the surface of the support rod 7. When the infusion needle 42 is stored inside the storage cavity 52, the fixing ball 9 at one end of the support rod 7 is pushed by the spring 8 and inserted into the groove 10 opened on the outer wall of the infusion needle 42, which limits the infusion needle 42 and prevents the infusion needle 42 from sliding out of the storage cavity 52. ​​When the handle 11 is pulled, the support rod 7 is moved to the outside, thereby moving the fixing ball 9 out of the groove 10, making it easy to take out the infusion needle 42 for puncture.

[0029] Please see Figure 2 The surface of the infusion tube 1 is slidably connected to a sliding sleeve 12, and two fixing strips 13 are connected to both sides of the surface of the sliding sleeve 12. The two fixing strips 13 are glued together by Velcro.

[0030] In practical use: the surface of the infusion tube 1 is slidably connected to a sliding sleeve 12, and the two sides of the surface of the sliding sleeve 12 are connected to fixing strips 13. During infusion, by pulling the two fixing strips 13, they are attached to the surface of the object through the Velcro on the surface of the fixing strips 13, so as to fix the infusion tube 1 and prevent the infusion tube 1 from swinging and being pulled.

[0031] Please see Figure 1 , Figure 2 An exhaust pipe 14 is fixedly connected to the bottom surface of the puncture device 2.

[0032] In actual use: The bottom surface of the puncture device 2 is fixedly connected to an exhaust pipe 14 for venting air.

[0033] Please see Figure 2 A flow rate regulator 15 is installed on the surface of the infusion tube 1.

[0034] In practical use: the flow rate regulator 15 on the surface of the infusion tube 1 is used to control the infusion rate.

[0035] A flexible tube 41 is connected to the other end of the infusion tube 1. An infusion needle 42 is slidably fitted onto the surface of the flexible tube 41. A needle wing 43 is connected to the tail end of the infusion needle 42. During puncture, the infusion needle 42 is inserted into the blood vessel. At the same time, the flexible tube 41 enters the blood vessel together. By pulling the needle wing 43, the infusion needle 42 moves on the surface of the flexible tube 41 and withdraws from the blood vessel, leaving the flexible tube 41 in the blood vessel. This infusion method replaces leaving the steel needle inside the blood vessel, which can reduce drug extravasation, facilitate the patient's hand movement, and avoid puncture wounds to the blood vessel. When the infusion needle 42 is withdrawn from the blood vessel, the needle wing 43 slides inside the strip groove 53, causing the infusion needle 42 to be stored in the storage cavity 52, preventing the infusion needle 42 from being exposed to the outside and causing puncture wounds to personnel. The storage box 51 serves to collect and protect the infusion needle 42.
