[0003] At present, the types and shapes of medical water stop clamps are relatively uniform, and most of them are set as open arc-shaped plate structures, such as a water stop clamp disclosed in a Chinese patent with publication number CN107335110B, which includes a water clamp body with a "C" shaped outer contour, the water clamp body includes a base, the two sides of the base are respectively fixed with a left part and a right part, and a gap is provided between the left part and the right part; the left part is a triangular movable frame, the lower part of which is a compression part, and the upper end of which is a movable end, and the fixed end is fixed with the base as a whole; the lower part of the right part is a fixed end fixed with the base, and also such as a water stop clamp disclosed in a Chinese patent with patent number CN203107862U, which includes an open water stop clamp body, a clamping block is provided on one side of the open water stop clamp body, a clamping pin is provided on the clamping block, a clamping groove is provided on the other side of the open water stop clamp body, and a clamping block is provided on the inner side of the clamping groove; a catheter guide groove is provided on the inner surface of one side of the water stop clamp body, and a protrusion is provided on the inner surface of the other side to cooperate with the catheter guide groove; a catheter passage is provided on the water stop clamp body on both sides of the catheter guide groove.

[0004] No matter which kind of water stop clamp is used, the water stop clamp needs to be sleeved on the hose, and is arranged along the length direction of the hose, by pressing the plate body at the opening, the protrusions on the inner side of the water stop clamp can be pressed to cut off the passage of the liquid in the hose.

[0005] Although the above operation can realize the limitation of the water stop clamp on the liquid passage, the existing water stop clamp has some problems:

[0006] Firstly, the above water stop clamp has a single function, specifically, it cannot realize different degrees of extrusion on the hose, that is, it either completely extrudes the hose to cut off the liquid passage or does not contact with the hose at all, which is not convenient for adjusting the rate of liquid passage according to the actual demand of drug liquid injection;

If it is found that the water stop clamp has a problem in the post-production inspection process, the soft tube of the drip infusion device needs to be cut or the water stop clamp needs to be cut. The soft tube is relatively easy to cut, but loss is caused. The water stop clamp is usually made of thick material, so it is relatively difficult to cut the water stop clamp. If it is found that the water stop clamp has a problem after being put into use, the entire drip infusion device will be discarded because the water stop clamp cannot be replaced, or the water stop clamp is discarded together with the drip infusion device because the drip infusion device has other quality problems, so that resources are wasted.

[0036] The following further illustrates the specific embodiments and the accompanying drawings:

[0037] Embodiment 1

[0038] In the background art, it is recorded that the water stop clamp mounted on the infusion device is inconvenient to adjust the degree of squeezing the hose according to the demand, is not conducive to adjusting the flow rate of the drug liquid, in addition, the water stop clamp cannot be detached from the infusion device, and when the infusion device has a problem, the water stop clamp is likely to be wasted. In order to solve the above problems, the present embodiment improves the existing water stop clamp and provides a new technical scheme.

[0039] As Figure 1 shown, the existing water stop clamp includes a lower pressing plate 3, a first arc-shaped plate 1 and a second arc-shaped plate 2, the end portions of the first arc-shaped plate 1 and the second arc-shaped plate 2 are connected to form a main body with an opening upward, the lower pressing plate 3 is connected to the end portion of the first arc-shaped plate 1 away from the second arc-shaped plate 2, that is, the lower pressing plate 3 is arranged at the opening of the main body, and the end of the lower pressing plate 3 away from the first arc-shaped plate 1 can extend into the barb arranged on the top of the second arc-shaped plate 2, under the action of the barb, the lower pressing plate 3 and the main body form a closure. Because the lower pressing block 31 is arranged below the lower pressing plate 3, the supporting block 4 is arranged at the connection of the first arc-shaped plate 1 and the second arc-shaped plate 2, when the lower pressing plate 3 and the main body form a closure, the lower pressing block 31 and the supporting block 4 are in contact. In addition, the first through hole 11 and the second through hole 21 are arranged on the first arc-shaped plate 1 and the second arc-shaped plate 2 respectively, so that the hose of the infusion device is arranged through the first through hole 11 and the second through hole 21, that is, the water stop clamp is arranged on the infusion device, when the lower pressing plate 3 and the main body are closed, the lower pressing plate 3 and the supporting block 4 squeeze the hose to cut off the liquid medicine flow channel.

[0040] As Figure 7 , Figure 8As shown in the figure, in order to adjust the flow rate of the liquid medicine in the hose according to the needs, the barb installed on the top of the second arc-shaped plate 2 is removed, and a connecting mechanism is provided instead, which is used to connect the top of the second arc-shaped plate 2 and the end of the pressing plate 3 away from the first arc-shaped plate 1, and the state of the connecting mechanism can be controlled by the person, changing the position of the end of the pressing plate 3 relative to the second arc-shaped plate 2, providing convenience for changing the size of the gap between the pressing block 31 and the supporting block 4, and then realizing the different degrees of extrusion of the hose, providing support for adjusting the flow rate of the liquid medicine. In addition, the setting of the connecting mechanism changes the current situation that the end of the second arc-shaped plate 2 needs to be moved to release the restriction of the pressing plate 3, avoiding the difficulty in moving the second arc-shaped plate 2 due to the thick water stop clamp.

[0041] As shown in the figure, Figure 7 The connecting mechanism includes an end plate 34 and a connecting hole 24, the connecting hole 24 is provided on the top of the second arc-shaped plate 2, and the upper end is provided as an opening, a plurality of buckle grooves 25 are provided on the side wall of the connecting hole 24, the plurality of buckle grooves 25 are arranged along the height direction of the connecting hole 24, and the end plate 34 is provided with two, which are both vertically arranged on the end of the pressing plate 3, the distance between the two side walls of the two end plates 34 away from each other is greater than the width of the connecting hole 24, and the end of the two end plates 34 away from the pressing plate 3 can approach each other under the action of external force, so when the hose needs to be extruded, the person holds the end of the end plate 34 and makes the two end plates 34 pass through the connecting hole 24, and after relaxing the end of the end plate 34, the two end plates 34 will reset, at this time the edges away from each other are located in the buckle groove 25, under the action of the buckle groove 25, the end plate 34 can be stably placed relative to the second arc-shaped plate 2, forcing the pressing block 31 and the supporting block 4 to extrude the hose. Because a plurality of buckle grooves 25 are provided, the edges of the end plate 34 can be controlled to extend into a certain buckle groove 25 according to the needs, so as to realize the different degrees of extrusion of the hose and adjust the flow rate of the liquid medicine.

[0042] Example 2

[0043] It is described in the background art that the water stop clamp installed on the infusion device is not convenient to adjust the degree of extrusion of the hose according to the needs, which is not conducive to adjusting the flow rate of the liquid medicine, in addition, the water stop clamp cannot be removed from the infusion device, which is likely to cause waste of the water stop clamp when the infusion device has a problem. In order to solve the above problems, the present embodiment improves the existing water stop clamp and provides a new technical solution.

[0044] As shown in the figure, Figure 1As shown, the existing water stop clamp comprises a pressing plate 3, a first arc-shaped plate 1 and a second arc-shaped plate 2. The end portions of the first arc-shaped plate 1 and the second arc-shaped plate 2 are connected to form a main body with an opening upward. The pressing plate 3 is connected to the end portion of the first arc-shaped plate 1 away from the second arc-shaped plate 2, i.e. the pressing plate 3 is arranged at the opening of the main body. The end of the pressing plate 3 away from the first arc-shaped plate 1 can extend into a hook arranged on the top of the second arc-shaped plate 2. Under the action of the hook, the pressing plate 3 can form a closure with the main body. A pressing block 31 is arranged below the pressing plate 3. A supporting block 4 is arranged at the connection portion of the first arc-shaped plate 1 and the second arc-shaped plate 2. When the pressing plate 3 forms a closure with the main body, the pressing block 31 and the supporting block 4 are in contact. In addition, a first through hole 11 and a second through hole 21 are arranged on the first arc-shaped plate 1 and the second arc-shaped plate 2 respectively. Therefore, the hose of the infusion device can pass through the first through hole 11 and the second through hole 21, i.e. the water stop clamp can be arranged on the infusion device. When the pressing plate 3 forms a closure with the main body, the pressing plate 3 and the supporting block 4 can extrude the hose to cut off the flow path of the liquid medicine.

[0045] As shown in Figure 7 , Figure 8 , in order to adjust the flow rate of the liquid medicine in the hose according to the needs, the hook arranged on the top of the second arc-shaped plate 2 is removed, and a connecting mechanism is arranged instead. The connecting mechanism is used to connect the top of the second arc-shaped plate 2 and the end of the pressing plate 3 away from the first arc-shaped plate 1. The state of the connecting mechanism can be controlled by personnel, so as to change the position of the end of the pressing plate 3 relative to the second arc-shaped plate 2, facilitate the change of the size of the gap between the pressing block 31 and the supporting block 4, and further extrude the hose to different degrees, so as to provide support for adjusting the flow rate of the liquid medicine. In addition, the arrangement of the connecting mechanism changes the current situation that the end of the second arc-shaped plate 2 needs to be bent to remove the restriction of the pressing plate 3, so as to avoid the inconvenience of bending the second arc-shaped plate 2 due to the thickness of the water stop clamp.

[0046] As shown in Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13As shown, the connecting mechanism is provided as a connecting assembly 6, which comprises a second threaded column 63, a first ball 61 and a second ball 62, the first ball 61 and the second ball 62 are respectively provided at the upper and lower ends of the second threaded column 63, a threaded hole 66 is provided on the first ball 61, a counterbore 64 is provided on the second ball 62, a blocking column 65 is provided on the first ball 61 and the second ball 62, a blocking disc 67 is provided at the bottom of the second threaded column 63, and a rotating disc 68 is provided at the top of the second threaded column 63, the bottom of the second threaded column 63 penetrates through the second ball 62, and the top is threaded through the threaded hole 66, and the blocking disc 67 is located at the counterbore 64.

The first ball 61 and the second ball 62 are respectively arranged in the U-shaped grooves of the lower pressing plate 3 and the second arc-shaped plate 2, and the blocking column 65 is installed in the arc-shaped blocking groove through the in-out groove. Because the lower pressing plate 3 and the second arc-shaped plate 2 always have a tendency to move away from each other, after the connecting assembly 6 is installed at the adjacent ends of the lower pressing plate 3 and the second arc-shaped plate 2, it can be stably placed. During the use of the water stop clamp, the second threaded column 63 can be rotated to change the distance between the first ball 61 and the second ball 62, force the position of the adjacent ends of the lower pressing plate 3 and the second arc-shaped plate 2, adjust the gap between the lower pressing block 31 and the supporting block 4, and control the flow rate of the drug liquid in the hose.

[0047] In order to make the connecting assembly 6 more stably installed on the water stop clamp, the width of the in-out groove can be slightly smaller than the diameter of the arc-shaped blocking groove, so that when the blocking column 65 is installed in the arc-shaped blocking groove, it is less than by external force, and also needs to be installed in the arc-shaped blocking groove by external force. This operation can realize the stable installation of the connecting assembly 6.
