Description

Technical Field

[0001] This utility model relates to the field of human life, and more particularly to medical devices, especially to intravenous infusion sets, specifically a clamping device for intravenous infusion sets. Background Technology

[0002] Intravenous infusion is a common medical procedure in modern medicine. During clinical intravenous infusion, if patients are not careful due to activity, using mobile phones, eating, or using the toilet, the infusion set may be pulled out by external force. This not only leads to material replacement waste but may also cause injury to the patient. Utility Model Content

[0003] The purpose of this utility model is to provide a clamping device for intravenous infusion sets, which aims to solve the technical problem in the prior art that intravenous infusion sets are easily detached due to external forces.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A clamping device for an intravenous infusion set includes an upper clamping assembly and a lower clamping assembly. The upper clamping assembly includes an upper clamping body and an upper connector. The front side of the upper clamping body is provided with a U-shaped first clamping opening. A gripper is provided at the front end of each side of the first clamping opening. The front end of each gripper is bent inwards towards the first clamping opening. The rear end of each gripper is connected to the front end of the upper clamping body via a first reset mechanism. The lower clamping assembly includes a lower clamping body and a lower connector. The front side of the lower clamping body is provided with a U-shaped second clamping opening. The lower clamping body is positioned below the upper clamping body. The front end of the upper connector is connected to the rear end of the upper clamping body, and the front end of the lower connector is connected to the rear end of the lower clamping body. The upper connector and the lower connector are connected via a second reset mechanism.

[0006] The first reset mechanism includes an upper plate and a lower plate. The upper plate is positioned above the lower plate. A vertical shaft is provided between the upper plate and the lower plate. The upper end and the lower end of the vertical shaft are respectively connected to the upper plate and the lower plate. The vertical shaft forms a rotating pair with the upper plate and the lower plate. A first torsion spring is provided on the outer periphery of the vertical shaft. The front end of the upper plate is connected to the rear end of the gripper, and the rear end of the lower plate is connected to the front end of the upper clamping body. Alternatively, the front end of the lower plate is connected to the rear end of the gripper, and the rear end of the upper plate is connected to the front end of the upper clamping body. The first torsion spring biases the gripper into a clamping state.

[0007] The upper connector is V-shaped with its opening facing upwards. The front end of the upper connector is connected to the rear end of the upper clamping body. The lower connector is also V-shaped with its opening facing downwards. The front end of the lower connector is connected to the rear end of the lower clamping body. The second reset mechanism includes a first through-hole, a second through-hole, and a horizontal shaft. The first through-hole extends vertically through the middle of the upper connector, and the second through-hole extends vertically through the middle of the lower connector. The middle of the upper connector has a first through-hole, and the middle of the lower connector has a second through-hole. The middle of the lower connector extends into the middle of the upper connector. The horizontal shaft is located in the second through-hole, with both ends passing through the second through-hole and the first through-hole respectively. The horizontal shaft forms a rotating pair with both the upper and lower connectors. A second torsion spring is located on the outer periphery of the horizontal shaft, biasing the upper and lower clamping assemblies into a clamped state.

[0008] Furthermore, each of the aforementioned grippers has a first guide ramp at its front end.

[0009] Furthermore, a second guide slope is provided on both sides of the front end of the lower clamp.

[0010] Working principle:

[0011] This device uses an upper clamping assembly to hold the mouth of the infusion bottle, and the upper and lower clamping assemblies keep the intravenous infusion set and the infusion bottle tightly connected.

[0012] Compared with the prior art, the advantages of this utility model are: simple operation, keeping the intravenous infusion set and infusion bottle in close contact, and preventing the intravenous infusion set and infusion bottle from accidentally detaching. Attached Figure Description

[0030] Install:

[0031] Step 1: Press the rear parts of the upper connector 2 and the lower connector 8 in opposite directions to open the upper clamp 1 and the lower clamp 7.

[0032] Step two, push the two grippers 3 outwards from both sides to open them.

[0033] Step 3: Insert the upper clamp 1 from bottom to top into the mouth of the intravenous infusion bottle.

[0034] Step four: Release the gripper 3. The two grippers 3 will return to their original position under the action of the first torsion spring 4, thus clamping the mouth of the intravenous infusion bottle.

[0035] Step 5: Align the infusion set with the opening of the intravenous infusion bottle.

[0036] Step six: Loosen the upper connector 2 and the lower connector 8, so that the upper clamp 1 and the lower clamp 7 come together and tighten. Under the action of the second torsion spring 12, the infusion set is locked in place, thus preventing it from falling off.

[0037] tear down:

[0038] Step 1: Press the rear parts of the upper connector 2 and the lower connector 8 in opposite directions to open the upper clamp 1 and the lower clamp 7.

[0039] Step two, remove the infusion set.

[0040] Step 3: Push the two grippers 3 outwards to open them.

[0041] Step four: Remove the device from the opening of the intravenous infusion bottle.

[0042] Step 5: Loosen the upper connector 2 and the lower connector 8 to restore the device to its original state.

[0043] The torsion spring that can be selected is the economical model FHC01-D6-n5, which requires a 2.3N drive (reference data: the force of an adult woman's fist is 27N-30N).
