Description

Technical Field

[0001] This utility model belongs to the field of medical accessory technology, specifically relating to a fixator and an infusion set that prevents the infusion set from falling off. Background Technology

[0002] Infusion sets, as key equipment in the medical system, are widely used in intravenous infusion therapy. They typically consist of components such as a conical connector, tubing, drip chamber, flow regulator, and stopper puncture device. The conical connector connects to the needle, and the stopper puncture device penetrates the stopper of the infusion bottle to form a drug infusion channel. However, in actual clinical applications, the connection method between the infusion set and the infusion bottle has significant shortcomings. Currently, this connection mainly relies on the friction between the stopper and the stopper puncture device. Because the stopper puncture device is not effectively secured, this connection method is particularly vulnerable to anxious patients who deliberately pull on the infusion set, or patients who unconsciously pull on the infusion set while comatose or asleep. Once the pulling force exceeds the friction force, the infusion set will detach from the infusion bottle, resulting in drug waste or even contamination of the infusion set, requiring replacement, increasing the patient's medical costs, and wasting medical resources. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a fixator and infusion set that prevent the infusion set from falling off, thereby solving the problem that the bottle stopper of the existing infusion set is not effectively fixed, which leads to the risk of it falling off under tension.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a fixator and an infusion set for preventing infusion set from falling off, comprising a fixator body and an infusion set body. The fixator body is composed of a fixing clamp, a roll, a connecting strap, and a fastener. The fixing clamp is used to hold the neck of the infusion bottle. The roll is disposed on the fixing clamp, and one end of the connecting strap is connected to the inner spool of the roll, while the other end passes through the roll and is connected to the fastener located on the outside. The roll has a locking hole and a clamping plate. The clamping plate is provided with a locking strip and a spring locking block, and the spring locking block is connected to the locking hole to fix the clamping plate. The bottle stopper puncture needle seat of the infusion set body is provided with a hanging ring, and the hanging ring is connected to the fastener.

[0005] The beneficial effects of this utility model are as follows: After the infusion bottle stopper is punctured by the puncture needle of the infusion set, the hanging ring on it is connected to the fastener of the fixing body installed on the infusion bottle. This can effectively limit the risk of the infusion set falling off due to the accompanying tension. It avoids the risk that if the infusion set falls off, it will not only lead to waste of medicine, but also cause pollution to itself, increase the patient's medical costs, and bring the patient the pain of a second puncture.

[0006] To facilitate the length adjustment and automatic winding of the connecting belt:

[0007] As a further improvement to the above technical solution: both sides of the fixing clamp are provided with a roller, which winds up the connecting belt through an internal roller, and the roller is provided with a coil spring.

[0008] The beneficial effects of this improvement are as follows: by setting up a drum and installing a coil spring on the shaft inside the drum, the coil spring installed on the shaft can deform under force after the connecting belt is pulled outward and the length of the connecting belt is adjusted, storing a certain amount of elastic energy. When the tension on the connecting belt is removed, the coil spring releases the stored elastic energy and drives the shaft to rotate to automatically wind up the connecting belt.

[0009] To facilitate the fixing and unfolding of the clamps:

[0010] As a further improvement to the above technical solution: the clamping plate is located on the outer side of the lower end of the drum, and one end of the clamping plate is hinged to the drum, while the other end is provided with a spring clip, which is connected to the corresponding hole on the drum.

[0011] The beneficial effects of this improvement are: after the spring block and the locking hole are connected, the position of the clamp can be fixed. When the spring block is pressed and moved inward to separate from the locking hole, the clamp can be unfolded.

[0012] To facilitate the automatic inward rewinding of the connecting tape:

[0013] As a further improvement to the above technical solution: the clip is located inside the clamping plate, and there are several clips, which are used to restrict the rewinding of the connecting belt under the fixation of the clamping plate.

[0014] The beneficial effects of this improvement are as follows: by setting up the retaining strip, after the length adjustment operation of the connecting strip is completed, it is only necessary to fix the clamp plate and press the retaining strip against the connecting strip, which can restrict the connecting strip from automatically rolling inward, so that it maintains its current length and is connected to the body of the infusion set.

[0015] To facilitate connection with the fasteners, the fixator body and the infusion set body can be linked.

[0016] As a further improvement to the above technical solution: both sides of the needle seat of the infusion set body bottle stopper puncture needle are horizontally provided with hanging rings.

[0017] The beneficial effect of this improvement is that, by setting up the hanging ring, the connection between the fixation device body and the infusion set body can be achieved through cooperation with the fastener. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0024] like Figure 1-4As shown, a fixator for preventing infusion set dislodgement and an infusion set include a fixator body 1 and an infusion set body 2. The fixator body 1 is composed of a fixing clamp 3, a reel 4, a connecting strap 5, and a fastener 6. The fixing clamp 3 is used to clamp the neck of the infusion bottle. The reel 4 is disposed on the fixing clamp 3, and one end of the connecting strap 5 is connected to the internal reel of the reel 4, while the other end passes through the reel 4 and is connected to the fastener 6 located on the outside. The reel 4 has a locking hole 7 and a clamping plate 8. The clamping plate 8 is provided with a locking strip 9 and a spring locking block 10, and the spring locking block 10 is connected to the locking hole 7 to fix the clamping plate 3. The infusion set body 2 has a bottle stopper puncture needle seat. The device is equipped with a hanging ring 11, which is connected to the fastener 6. After the infusion bottle stopper is punctured by the puncture needle, the hanging ring 11 is connected to the fastener 6 of the fixing body 1 installed on the infusion bottle. This effectively limits the risk of the infusion set falling off due to tension, preventing the infusion set from falling off, which would not only waste the medication but also contaminate the set itself, increase the patient's medical costs, and cause the patient pain from a second puncture. Both sides of the fixing clamp 3 are equipped with a reel 4. The reel 4 winds the connecting belt 5 through an internal roller, and the roller is equipped with a coil spring. Furthermore, a coil spring is installed on the shaft inside the drum 4. When the connecting belt 5 is pulled outwards and its length adjusted, the coil spring on the shaft deforms under force, storing a certain amount of elastic energy. When the pulling force on the connecting belt 5 is released, the coil spring releases the stored elastic energy, driving the shaft to rotate and automatically rewind the connecting belt 5. The clamping plate 8 is located on the outer side of the lower end of the drum 4, with one end hinged to the drum 4 and the other end equipped with a spring catch 10. The spring catch 10 engages with the corresponding hole 7 on the drum 4. The engagement of the spring catch 10 with the hole 7 fixes the position of the clamping plate 8. When pressed... When the spring block 10 moves inward and separates from the locking hole 7, the clamp 8 can be unfolded. The locking strip 9 is located inside the clamp 8, and there are several locking strips 9. They are used to restrict the rewinding of the connecting strip 5 when the clamp 8 is fixed. With the setting of the locking strip 9, after the length adjustment operation of the connecting strip 5 is completed, it is only necessary to fix the clamp 8. The locking strip 9 presses against the connecting strip 5, which can restrict the connecting strip 5 from automatically rewinding inward, so that it maintains its current length and is connected to the infusion set body 2. The needle seat of the puncture needle of the bottle stopper of the infusion set body 2 is horizontally provided with hanging rings 11 on both sides. With the setting of the hanging rings 11, the connection between the fixator body 1 and the infusion set body 2 can be realized by cooperating with the fastener 6.

[0025] The working principle of this utility model is as follows: When performing infusion therapy, simply take the fixation body 1 and clamp the fixing clip 3 at the neck of the infusion bottle. After the bottle stopper puncture needle of the infusion set body 2 is completed, press the spring clip 10 to move inward and separate it from the locking hole 7. Unfold the clamp 8 to release the restriction on the connecting strap 5. Pull down the connecting strap 5 so that the buckle 6 at its bottom end engages with the hanging ring 11 on the infusion set body 2. With the coil spring driving the roller to rotate and automatically rewind the connecting strap 5, the connecting strap 5 automatically adapts to the connection distance between the fixation body 1 and the infusion set body 2. At this time, simply rotate the clamp 8 to engage the spring clip 10 with the locking hole 7 to fix the clamp 8 and make the locking strip 9 press against the connecting strap 5, thereby restricting the movement of the connecting strap 5 and preventing the infusion set body 1 from causing the connecting strap 5 to move outward under tension, which would affect the connection stability.
