Description

Technical Field

[0001] The utility model relates to the technical field of infusion sets, in particular to an anti-falling mechanism for an infusion set. Background Art

[0002] The connection between the infusion set and the mouth of the infusion bottle mainly relies on the sharp part of the infusion set piercing into the bottle. There is no fixing device and it is easy to fall off.

[0003] For example, a Chinese utility model patent with authorization announcement number CN211675655U discloses an improved anti-drop infusion device, including an infusion tube, a connector is provided on the outside of one end of the infusion tube, a connection hole is provided on one side of the connector, a connection line is provided on one side of the connector, and a clamping device is provided on the end of the connection line away from the connector; the clamping device includes a first clamping ring and a second clamping ring, a first connecting piece is tightly welded to one end of the first clamping ring, a second connecting piece is tightly welded to one end of the second clamping ring close to the first connecting piece, the first connecting piece is located at the top of the second connecting piece, a rotating shaft is vertically provided on the top of the first connecting piece, a torsion spring is wound around the outside of the rotating shaft, the bottom end of the rotating shaft passes through the first connecting piece and is tightly welded to the second connecting piece, and the rotating shaft is rotatably connected to the first connecting piece. The utility model has a simple structure and is easy to use. The clamping device can facilitate the placement and fixation of the infusion tube to avoid the slippage of the infusion tube.

[0004] The above-mentioned authorized patent has the following problems during use:

[0005] The connector and the infusion tube cannot be disassembled. Since the infusion sets are disposable, the anti-falling mechanism on the infusion sets must also be discarded after the infusion sets are discarded, which makes the anti-falling mechanism of the infusion sets unable to be recycled, which is quite wasteful. In addition, the anti-falling mechanism of the infusion set uses the elastic force generated by the torsion spring to fix the first clamping ring and the second clamping ring to the infusion bottle. Since the elastic force of the torsion spring is small, it is easy for the anti-falling mechanism of the infusion set to fail to be firmly fixed on the infusion bottle. Moreover, the curvature of the first clamping ring and the second clamping ring is fixed, which makes it impossible for the first clamping ring and the second clamping ring to be fixed on infusion bottles of different diameters, resulting in poor adaptability.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original anti-falling mechanism of the infusion set. Utility Model Content

[0013] Preferably, the clamping plate is designed to be an arc-shaped structure, and the two clamping plates form a circular ring shape.

[0014] Preferably, two connecting ropes are provided.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows: the anti-falling mechanism of the infusion set uses two fingers to press the two pressing plates together, at which time the spring is compressed, and at the same time the two pressing plates drive the left clamping plate to rotate clockwise around the central axis of the rotating shaft, and the right clamping plate to rotate counterclockwise around the central axis of the rotating shaft, so that the openings of the two clamping plates are opened, and then the two clamping plates are installed on the spiked part of the infusion set, and then the force of the fingers is slowly reduced, and under the elastic force of the spring, the openings of the two clamping plates are closed, so that the two clamping plates are clamped on the spiked part of the infusion set, thereby facilitating the rapid installation of the anti-falling mechanism of the infusion set on the spiked part of the infusion set, improving the working efficiency, and at the same time the anti-falling mechanism of the infusion set can be disassembled from the spiked part of the infusion set, so that the anti-falling mechanism of the infusion set can be recycled;

[0016] By rotating the handle forward or backward, the distance between the fixed plate and the movable plate can be increased or decreased, so that the diameter of the front part of the fixed rope can be decreased or increased, so that the fixed rope can be fixed on infusion bottles of different diameters, thereby improving the versatility of the anti-falling mechanism of the infusion set;

[0017] When the fixing rope is fixed on the infusion bottle, under the action of the fixing rope and the connecting rope, the clamping plate can prevent the sharp spike part of the infusion set from being separated from the infusion bottle. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6The utility model provides a technical solution: an anti-drop mechanism for an infusion set, comprising an infusion bottle 1, a rubber stopper at the bottom of the infusion bottle 1 penetrates an infusion set spike portion 2, a clamping structure 3 is arranged on the outside of the infusion set spike portion 2, a fixing structure 4 is arranged on the outside of the infusion bottle 1, the clamping structure 3 and the fixing structure 4 are connected to each other by a connecting rope 5, and two connecting ropes 5 are arranged;

[0027] The clamping structure 3 includes a clamping plate 31, and the ends of the two clamping plates 31 are rotatably connected by a rotating shaft 32. A pressing plate 33 is fixed to the outer wall of the clamping plate 31 near the rotating shaft 32, and a spring 34 is fixed between the two pressing plates 33. The outer side of the infusion set spike 2 and the inner side of the clamping plate 31 fit each other. The clamping plate 31 is designed as an arc structure, and the two clamping plates 31 form a circular ring. By pressing the two pressing plates 33, the openings of the two clamping plates 31 can be enlarged, which facilitates the rapid installation of the two clamping plates 31 on the infusion set spike 2.

[0028] The fixing structure 4 includes a fixing rope 41, and the fixing rope 41 is attached to the outer side of the infusion bottle 1. Both ends of the fixing rope 41 are fixedly connected to one side of the fixing plate 42, and both ends of the fixing rope 41 pass through the interior of the movable plate 43. A screw rod 44 is rotatably installed on one side of the movable plate 43 through a bearing, and the end of the screw rod 44 passes through the interior of the fixing plate 42 and is fixed with a handle 45. The end of the fixing plate 42 passes through a guide rod 46, and the end of the guide rod 46 is fixedly connected to one side of the movable plate 43. The fixing rope 41 is fixedly connected to the clamping plate 31 through a connecting rope 5, the fixing plate 42 and the screw rod 44 are threadedly connected, the guide rod 46 and the fixing plate 42 are slidably connected, and the movable plate 43 and the fixing rope 41 are slidably connected. By rotating the handle 45 forward or reversely, the distance between the fixing plate 42 and the movable plate 43 can be increased or decreased, so that the diameter of the front part of the fixing rope 41 can be reduced or increased, so that the fixing rope 41 can be fixed on infusion bottles 1 with different diameters.

[0029] A finger groove 35 is provided on one side of the pressing plate 33 away from the spring 34 , which reduces the probability of separation of the finger from the pressing plate 33 and is conducive to pressing the two pressing plates 33 to move closer to each other.

[0030] Working principle: When using the anti-falling mechanism of the infusion set, first insert the spiked part 2 of the infusion set into the interior of the infusion bottle 1, then use two fingers to press the two pressing plates 33 together, at this time the spring 34 is compressed, and at the same time the two pressing plates 33 drive the left clamping plate 31 to rotate clockwise around the central axis of the rotating shaft 32, and the right clamping plate 31 to rotate counterclockwise around the central axis of the rotating shaft 32, so that the openings of the two clamping plates 31 are opened, and then the two clamping plates 31 are installed on the spiked part 2 of the infusion set, and then the force of the fingers is slowly reduced, and under the elastic force of the spring 34, the openings of the two clamping plates 31 are closed, so that the two clamping plates 31 are clamped on the spiked part 2 of the infusion set;

[0031] Then, the front part of the fixing rope 41 is put on the infusion bottle 1, and the fixing rope 41 is lifted up at the same time. Then, the fixing rope 41 pulls the clamping plate 31 upward through the connecting rope 5, and then the handle 45 is turned forward so that the handle 45 drives the screw rod 44 to rotate. Since the fixing plate 42 and the screw rod 44 are threadedly connected, and the guide rod 46 and the fixing plate 42 are slidingly connected, the screw rod 44 pushes the movable plate 43 and the guide rod 46 to move, so that the movable plate 43 moves close to the infusion bottle 1. The movable plate 43 moves on the fixing rope 41 at the same time, so that the diameter of the front part of the fixing rope 41 can be reduced, so that the fixing rope 41 is fixed on the infusion bottle 1. Under the action of the fixing rope 41 and the connecting rope 5, the clamping plate 31 can prevent the infusion device spike 2 from detaching from the infusion bottle 1.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
