Description

Technical Field

[0001] The utility model relates to the technical field of infusion devices, in particular to an anti-detachment device for an infusion tube. Background Technique

[0002] Infusion, also known as drip injection or intravenous drip, is a large-dose injection solution infused into the body through intravenous drip, and is an essential and important link in modern medical technology. When in use, the puncture needle of a disposable infusion set needs to be inserted into the rubber stopper of the infusion bottle to enable the flow of the liquid, and then the injection needle is inserted into the patient's body to make the drug flow into the patient's body.

[0003] Currently, when existing medical staff perform infusion operations on patients, they only insert the puncture needle into the rubber stopper of the infusion bottle without fixing the two, which makes the puncture needle at risk of detaching from the rubber stopper. If other people such as patients or their families accidentally bump into the infusion tube, the infusion needle at the top of the infusion tube often comes out of the infusion bottle, which will cause contamination of the infusion set and even drug contamination. The contamination of the infusion tube not only increases the risk of patient infection and the workload of medical staff, but also causes waste of consumables. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when other people such as existing patients or their families accidentally bump into the infusion tube, the infusion needle at the top of the infusion tube often comes out of the infusion bottle, which will cause contamination of the infusion set and even drug contamination. The contamination of the infusion tube not only increases the risk of patient infection and the workload of medical staff, but also causes waste of consumables, and to propose an anti-detachment device for an infusion tube.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An anti-detachment device for an infusion tube includes a ferrule provided with a groove. Two connecting plates are integrally formed on both sides of the top of the ferrule, and the same rotating shaft is inserted into one end of each of the two connecting plates. Pressure plates are rotatably connected to the outer surface of the rotating shaft. Torsion springs are sleeved on the outer surface of the rotating shaft, and the torsion springs are located between the two connecting plates. One end of the torsion spring is in contact with one side of the ferrule, and the other end of the torsion spring is in contact with the inner side of the pressure plate. The top ends of the pressure plates are integrally formed with telescopic rods, and claw holders are sleeved on the outer surface of the telescopic rods. The claw holders can slide up and down along the telescopic rods. A pressable pin is provided on one side of each telescopic rod. A plurality of card holes are formed on one side of each claw holder, and the card holes are engaged with the pins. A card slot is formed at the top end of the claw holder.

[0007] Further, the card slot is an arc-shaped structure, and the claw holder is an L-shaped structure.

[0008] Further, first anti-slip pads are fixedly connected to the inner walls of the card slots, and the first anti-slip pads are arranged oppositely.

[0009] Further, second anti-slip pads are fixedly connected to the inner sides of the clamping claws, and the second anti-slip pads are of an L-shaped structure and are arranged oppositely.

[0010] Further, a third anti-slip pad is fixedly connected to the outer surface of the pressing plate.

[0011] Further, stripe grooves are formed on the outer surfaces of the first anti-slip pad, the second anti-slip pad and the third anti-slip pad.

[0012] Further, an airbag pad is fixedly connected to the inner wall of the card sleeve. The airbag pad is of an arc-shaped structure, and a plurality of anti-slip grooves are formed on the outer surface of the airbag pad.

[0013] Further, clamping plates are arranged on one sides of the card sleeve and the pressing plate, and two ends of a torsion spring are respectively clamped with the two clamping plates.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. By adopting a structure design of an infusion tube anti-detachment device including a card sleeve, a connecting plate, a rotating shaft, a pressing plate, a torsion spring, a telescopic rod, a clamping claw, a pin and a card hole, when the pressing plate applies pressure through the connecting plate and the rotating shaft, the torsion spring in the pressing plate provides a reverse elastic force to ensure that the clamping claw stably maintains the pressure on the bottleneck of the infusion bottle, so that the whole clamping claw is firmly in contact with the bottleneck of the infusion bottle, and it is prevented that the needle falls off due to external force or other factors during the infusion process, thereby effectively avoiding the accidental detachment of the infusion tube, further protecting the safety of the infusion device, and reducing the risk of drug contamination and the possibility of patient infection.

[0016] 2. By arranging the first anti-slip pad, the second anti-slip pad and the third anti-slip pad, the friction force of the anti-detachment device can be increased to ensure the firm locking between objects. Even during the activities of other people such as patients or their families, the infusion tube and the infusion bottle are not easily detached, significantly improving the overall stability of the infusion device. The use of the airbag pad not only increases an additional buffering effect, reduces the extrusion of the infusion tube caused by extrusion or collision, but also improves the clamping effect, such as the safe connection between it and the infusion bottle when the patient moves violently.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Refer to Figures 1 - 4 , an anti - detachment device for an infusion tube, including a ferrule 1 provided with a groove. It is characterized in that two connecting plates 2 are integrally formed on both sides of the top of the ferrule 1, and the same rotating shaft 3 is inserted at one end of each of the two connecting plates 2. The outer surfaces of the rotating shafts 3 are rotatably connected with pressure plates 4, and torsion springs 15 are sleeved on the outer surfaces of the rotating shafts 3. The torsion springs 15 can provide reverse elastic force to ensure that the claws 7 stably maintain the pressure on the bottleneck of the infusion bottle, so that the entire claws 7 are in firm contact with the bottleneck of the infusion bottle. And the torsion springs 15 are located between the two connecting plates 2. One end of the torsion spring 15 is in contact with one side of the ferrule 1, and the other end of the torsion spring 15 is in contact with the inner side of the pressure plate 4. Telescopic rods 5 are integrally formed at the tops of the pressure plates 4, and claws 7 are sleeved on the outer surfaces of the telescopic rods 5. The claws 7 are of an L - shaped structure and can slide up and down along the telescopic rods 5. A pressable pin 6 is provided on one side of each telescopic rod 5. A plurality of claw holes 8 are formed on one side of each claw 7, and the claw holes 8 are engaged with the pins 6. A card slot 9 is formed at the top of the claw 7, and the card slot 9 is of an arc - shaped structure.

[0024] Among them, the inner walls of the card slots 9 are all bonded with first anti-slip pads 10. The first anti-slip pads 10 are used to firmly fix the mouth of the infusion bottle, enhancing the anti-detachment performance. The inner sides of the claw catches 7 are all bonded with second anti-slip pads 11, and the second anti-slip pads 11 are of an L-shaped structure. The outer surface of the pressing plate 4 is bonded with a third anti-slip pad 14. The third anti-slip pad 14 is used to prevent slipping caused by excessive elastic force of the torsion spring 15 when replacing the infusion package. Striped grooves are provided on the outer surfaces of the first anti-slip pad 10, the second anti-slip pad 11, and the third anti-slip pad 14. The settings of the first anti-slip pad 10, the second anti-slip pad 11, and the third anti-slip pad 14 can increase the friction force of the anti-detachment device, ensuring the firm locking between objects. Even during the activities of patients or family members and other people, the infusion tube and the infusion bottle are not easily detached, significantly improving the overall stability of the infusion set.

[0025] Among them, an airbag pad 12 is bonded to the inner wall of the ferrule 1. The airbag pad 12 is of an arc-shaped structure. The use of the airbag pad 12 not only adds an additional buffering effect, reducing the extrusion of the infusion tube caused by extrusion or collision, but also improves the clamping effect. For example, when the patient moves violently, its safe connection with the infusion bottle. And a plurality of anti-slip grooves 13 are provided on the outer surface of the airbag pad 12. Clamping plates 16 are provided on one side of the ferrule 1 and the pressing plate 4, and both ends of the torsion spring 15 are respectively clamped with the two clamping plates 16.

[0026] The working principle of this embodiment: During use, when using the infusion set, first insert the needle on the infusion handle into the bottom of the infusion bottle, and the other end needle is connected to the vein of the human body. Such a setting enables the drug to be gradually delivered to the patient's body at a controllable rate. Then, by engaging the airbag pad 12 on the ferrule 1 with the infusion handle, the design of the airbag pad 12 not only provides a certain clamping force for the infusion handle, but the plurality of anti-slip grooves 13 on its surface further increase the friction force, effectively preventing the relative sliding between the ferrule 1 and the infusion handle, ensuring the stability and effectiveness of the entire infusion process. Then, press the pressing plate 4 with one hand to separate the claw catches 7 to both sides, and then release the pressing plate 4. The pressing plate 4 returns to its original position under the action of the internal torsion spring 15 and drives the claw catches 7 to reset. The arc-shaped card slots 9 at both ends of the claw catches 7 are aligned with the bottleneck of the infusion bottle and are mutually engaged. The first anti-slip pad 10 in the card slot 9 fixes the bottleneck of the infusion bottle, and the second anti-slip pad 11 in the claw catch 7 can fix the bottle stopper of the infusion bottle. At the same time, considering that different infusion bottles or infusion bags may have different bottle stopper sizes and bottleneck lengths, the claw catches 7 can be adjusted. By pressing the pin 6 located above the claw catches 7, the user can disengage it from the card hole 8 while keeping the bottom structure stable, and pull up the claw catches 7 to adjust the distance between the claw catches 7 and the pressing plate 4, so as to effectively clamp or fix bottle stoppers of different sizes, ensuring the accuracy and safety of the delivery.
