Description

Technical Field

[0001] The utility model relates to the technical field of flow-stop clamps, in particular to a convenient flow-stop clamp. Background Art

[0002] A stop clamp is a medical product used to block the flow of liquid inside a hose during infusion or blood transfusion. Figure 1 As shown, a conventional stop clamp is typically made of plastic and includes an upper clamping piece 10 and a lower clamping piece 20. The upper clamping piece 10 has a latching tooth 11 and an upper pressing protrusion 12, while the lower clamping piece 20 has a latching tip 21 and a lower pressing protrusion 22. Upper and lower tube holes are formed in the upper and lower clamping pieces 10, 20, respectively. After the end of the hose passes through the upper and lower tube holes, the upper clamping piece 10 is pressed down until the latching tip 21 engages the rear end of the latching tooth 11. At this point, the upper and lower pressing protrusions 12 and 22 jointly clamp the hose. If the upper clamping piece 10 is not pressed down, the stop clamp does not close the hose, and the hose remains unobstructed.

[0003] However, this type of stop clamp is inconvenient to install. When using it, medical staff need to find the end of the hose and pass the hose end through the upper and lower tube holes before installing the stop clamp on the hose. Especially when the end of the hose is already connected to other medical instruments, it is necessary to remove the hose end, pass it through the upper and lower tube holes, install the stop clamp, and then reconnect the hose end to the corresponding medical instrument, which is very inconvenient. Utility Model Content

[0004] In view of the defects in the prior art, the purpose of the present invention is to provide a convenient flow-stop clamp that is very convenient to install and use.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0024] In addition, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. In the description of this utility model, "plurality" means more than two, unless otherwise specifically defined.

[0025] like Figure 2-Figure 5 As shown, the utility model provides a convenient flow-stop clamp, which includes a lower clamping plate 30 , an upper clamping plate 40 and a pressing assembly 50 .

[0026] The lower splint 30 is arranged below the upper splint 40 , and the first side of the lower splint 30 is connected to the first side of the upper splint 40 via an elastic member 33 , and the second side of the lower splint 30 is detachably connected to the second side of the upper splint 40 .

[0027] The pressing assembly 50 includes a fixing block 51 and a pressing block 52 . The fixing block 51 is fixedly mounted on the top of the lower clamping plate 30 , and the pressing block 52 is fixedly mounted on the bottom of the upper clamping plate 40 .

[0028] In the initial state, the second side of the lower clamping plate 30 and the second side of the upper clamping plate 40 are in an unconnected state.

[0029] When using the present invention, medical personnel only need to insert the hose between the upper clamping plate 40 and the lower clamping plate 30 from the side, and then connect the second side of the upper clamping plate 40 with the second side of the lower clamping plate 30. At this time, the pressing block 52 will press the contacted hose against the fixing block 51, thereby clamping the hose. The entire process does not require the end of the hose to be passed through the flow-stop clamp, making installation and use very convenient.

[0030] When the flow-stop clamp needs to be removed, the medical staff disconnects the second side of the upper splint 40 from the second side of the lower splint 30. Under the resetting action of the elastic member 33, the second side of the upper splint 40 opens, and then the flow-stop clamp can be removed.

[0031] In one embodiment, two limiting plates 60 are further included, which are respectively disposed on both sides of the fixing block 51 and fixedly connected to the lower clamping plate 30. A limiting slot 61 extending downward and passing through the top of the limiting plate 60 is formed.

[0032] After the hose is laterally inserted between the upper clamping plate 40 and the lower clamping plate 30, it is also necessary to place the hose in the retaining grooves 61 on the two retaining plates 60. This design can limit the position of the hose, allowing the subsequent pressing block 52 to stably press the hose against the fixing block 51, thereby preventing the hose from slipping and causing the pressing block 52 to lose its grip on the fixing block 51, thereby ensuring the clamping effect of the hose.

[0033] In one embodiment, a transversely extending arcuate slot 53 is formed on the top of the fixing block 51 , and the extending direction of the arcuate slot 53 is the same as the length direction of the limiting slot 61 . A curved surface 54 adapted to the arcuate slot 53 is formed on the pressing block 52 .

[0034] After the second side of the upper clamping plate 40 is connected to the second side of the lower clamping plate 30, the curved surface 54 on the clamping block 52 presses the contacting hose into the curved groove 53 on the fixing block 51, thereby clamping the hose. Compared to conventional methods in which the upper and lower clamping protrusions 12 and 22 jointly clamp the hose, the design of the curved surface 54 and the curved groove 53 increases the contact area between the clamping block 52 and the fixing block 51 and the hose, thereby improving the clamping effect.

[0035] In one embodiment, a clamping block 31 is fixedly mounted on the second side of the lower clamping plate 30 . A connecting plate 41 is fixedly mounted on the second side of the upper clamping plate 40 , and a clamping slot 42 adapted to the clamping block 31 is formed on the connecting plate 41 .

[0036] When the medical staff inserts the clamping block 31 into the clamping slot 42, the second side of the upper clamping plate 40 and the second side of the lower clamping plate 30 will be connected together, with a simple structure and convenient operation.

[0037] In one embodiment, a first guide surface 32 extending downward and tilting outward is formed on the top of the block 31 , and a second guide surface 43 extending upward and tilting inward is formed on the bottom of the connecting plate 41 . The second guide surface 43 is adapted to the first guide surface 32 .

[0038] Medical staff only need to install the hose between the upper splint 40 and the lower splint 30 from the side, and then move the second side of the upper splint 40 close to the second side of the lower splint 30. At this time, the second guide surface 43 will first contact the first guide surface 32, and the first guide surface 32 will apply an outward force to the second guide surface 43, and the connecting plate 41 will bend outward. When the block 31 is aligned with the slot 42, under the action of the reset force of the connecting plate 41, the block 31 will be inserted into the slot 42, and the second side of the upper splint 40 and the second side of the lower splint 30 will be connected together.

[0039] This design makes the connection between the second side of the upper splint 40 and the second side of the lower splint 30 more convenient, further facilitating the operation of medical staff.

[0040] When the flow-stop clamp needs to be removed, the medical staff moves the bottom of the connecting plate 41 outward until the block 31 is disengaged from the slot 42, and then flips the second side of the upper clamp 40 upward to remove the flow-stop clamp.

[0041] In one embodiment, the elastic member 33 and the connecting plate 41 are made of elastic plastic, so that the elastic member 33 and the connecting plate 41 have good elasticity, thereby increasing the service life of the elastic member 33 and the connecting plate 41 .

[0042] Other parts of the present invention are made of traditional plastic materials.

[0043] Specifically, the elastic member 33 and the connecting plate 41 can be made of materials such as ABS plastic, polystyrene or polyamide.

[0044] In one embodiment, a hanging hole 44 is provided on the lower splint 30 to facilitate medical personnel to hang the present invention on an IV stand or other objects by means of a rope.

[0045] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all points of view, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.

[0046] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
