Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to an umbilical cord clamp. Background Technology

[0002] After a newborn's umbilical cord is cut, a wound is formed, which is an important gateway for bacteria to enter the newborn's body. In mild cases, it can cause inflammation, and in severe cases, it can lead to sepsis and death. Therefore, disinfection and care of the umbilical cord are very important.

[0003] In the existing technology, the umbilical cord clamp uses a mother-child separation type umbilical cord clamp. During operation, the push-cutting rod is pushed by hand to actively cut the umbilical cord like a syringe. It is not only easy to cut but also has a good cutting effect and saves effort. Because it is clamped before cutting, blood splatter can be avoided, thus protecting the physical and mental health of medical staff.

[0004] However, the relevant technology has at least one of the following problems: when the rod is pushed from the rear, since the force is applied from the end where the sub-clamp and the main body are joined, the sub-clamp is prone to get stuck on the main body and cannot be separated, resulting in a dangerous situation where the umbilical cord of the mother and baby cannot be detached. Utility Model Content

[0005] The technical problem solved by this utility model is that when the rod is pushed from the rear, the force is applied from one end where the sub-clamp and the main body are joined, and the sub-clamp is easily stuck on the main body and cannot be separated, resulting in a dangerous situation where the umbilical cord of the mother and baby cannot be detached.

[0006] To solve the above problems, this utility model provides an umbilical cord clamp, which includes: a main body, on the first side of the main body are a first positioning post and a second positioning post arranged at intervals; a sub-clamp, on one side of the sub-clamp is a main positioning cavity, the first positioning post and the second positioning post cooperate with the main positioning cavity to install the sub-clamp on the main body; wherein, the length of the second positioning post is less than the length of the first positioning post, and when pressure is applied to the sub-clamp from the side of the first positioning post away from the second positioning post, the sub-clamp detaches from the main body.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: the sub-clamp is installed on the main body of the umbilical cord clamp through the cooperation of the main positioning cavity, the first positioning post, and the second positioning post; and by setting the first and second positioning posts at intervals, the sub-clamp can be stably installed on the main body and will not fall off due to shaking; by setting the length of the second positioning post to be shorter than that of the first positioning post, on the one hand, the longer first positioning post can ensure the stability of the sub-clamp when it is installed on the main body, and on the other hand, if you want to remove the sub-clamp, you can lift it from the end where the first positioning post is located, and the shorter second positioning post will not hinder the removal of the sub-clamp, making it easy to remove the sub-clamp; this design facilitates the installation of the sub-clamp, improves stability, and facilitates disassembly, thus improving overall efficiency.

[0008] In one embodiment of this utility model, a top plate is provided on the second side of the main body away from the first positioning post, and a third positioning post is provided on the top plate; wherein, the sub-clamp is provided with a secondary positioning cavity that cooperates with the third positioning post, and when the sub-clamp is installed to the main body, the third positioning post is inserted into the secondary positioning cavity.

[0009] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting a top plate on the main body, when disassembling the sub-clamp, the end of the sub-clamp away from the first positioning post rests against the top plate, providing a force point for disassembly and reducing the lateral force on the first and second positioning posts, thus facilitating disassembly. Furthermore, by setting a third positioning post on the top plate, the end of the sub-clamp away from the first positioning post moves with the third positioning post as a fulcrum during disassembly, allowing the sub-clamp to move along its designed disassembly path without unnecessary slippage, thereby improving disassembly efficiency. On the other hand, since the third positioning post is not on the same side as the first and second positioning posts, when the sub-clamp moves away from the main body towards the first and second positioning posts, it experiences resistance from the third positioning post, making the sub-clamp more stable when mounted on the main body and preventing easy slippage.

[0010] In one embodiment of this utility model, the third positioning post is provided with a first conical guide surface; the inner wall of the secondary positioning cavity is provided with a second conical guide surface.

[0011] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: by setting a first conical guide surface on the third positioning post and a second conical guide surface on the inner wall of the sub-positioning cavity, the third positioning post can move to a certain extent in the sub-positioning cavity when the sub-clamp is disassembled, and the end of the sub-clamp away from the first positioning post can move better with the third positioning post as the fulcrum, thereby facilitating the disassembly of the sub-clamp.

[0012] In one embodiment of this utility model, the diameter of the first positioning post is 1.6mm-2.2mm and the length is 4mm-4.5mm; and / or the diameter of the second positioning post is 1.5mm-2.0mm and the length is 1.3mm-1.8mm; and / or the root diameter of the third positioning post is 1.7mm-2.2mm, the top diameter is 1.1mm-1.6mm, and the length is 2.3mm-2.8mm.

[0013] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting the specific lengths and diameters of the first, second, and third positioning posts, the sub-clamp can find a balance between stable installation and easy disassembly. If the second and first positioning posts are too long, the sub-clamp cannot be disassembled. If the first and second positioning posts are too short, they are prone to falling off the main body, making the umbilical cord clamp inconvenient to use.

[0014] In one embodiment of this utility model, the distance between the top plate and the second fixed post is 16mm-18mm, and the distance between the second fixed post and the first fixed post is 20mm-22mm.

[0015] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: by setting the distance between the first positioning post and the second positioning post, and the distance between the second positioning post and the top plate, a ratio that makes it easy for the sub-clamp to be disassembled is found, so that the set disassembly route is stable and reasonable.

[0016] In one embodiment of this utility model, the umbilical cord clamp also includes a push-cutting rod, one side of which is provided with a slide rail, and the main body is provided with a slide groove that cooperates with the slide rail; wherein, applying pressure to the push-cutting rod enables the front end of the push-cutting rod to pass through the sliding gap between the sub-clamp and the main body, and when the push-cutting rod applies pressure to the sub-clamp from the side of the first positioning post away from the second positioning post, the sub-clamp detaches from the main body.

[0017] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: by setting a slide rail on the push-cutting rod and setting a corresponding slide groove on the main body, the push-cutting rod can slide on the main body and slide to the sliding gap, thereby cutting the umbilical cord clamped by the dummy clamp and the main body; on the other hand, after the push-cutting rod cuts the umbilical cord, continuing to push can also apply pressure to the dummy clamp, thereby separating the dummy clamp that has clamped the umbilical cord from the main body, thus improving efficiency.

[0018] In one embodiment of this utility model, an ejector is provided on the side of the push-cutting rod near the sub-clamp, and the ejector is located in the middle of the push-cutting rod; wherein, when the ejector moves to the sliding gap, the ejector applies a force to the sub-clamp from the main body to the sub-clamp, causing the sub-clamp to detach from the main body.

[0019] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: by setting an ejector on the side of the push-cutting rod near the clamp, when the push-cutting rod slides in the sliding gap, the ejector moves to the end of the sub-clamp near the first positioning post to apply pressure, thereby ejecting the sub-clamp from the main body; on the other hand, the ejector needs to be set on the push-cutting rod at a position away from the front end to ensure that the push-cutting rod completely cuts the umbilical cord before ejecting the sub-clamp.

[0020] In one embodiment of this utility model, the ejector has a guide surface on the side near the sub-clamp, and the angle of inclination of the guide surface relative to the push-cutting rod is 135-140°.

[0021] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: In order to facilitate the ejector to eject the sub-clamp from the main body, it is necessary to set a guide surface with a slope and set a reasonable angle. This can eject the sub-clamp with less effort, while not occupying too much space on the push-cutting rod to affect other components.

[0022] By adopting the technical solution of this utility model, the following technical effects can be achieved:

[0023] (1) By setting the first positioning post and the second positioning post at intervals, the sub-clamp can be stably installed on the main body and will not fall off due to shaking;

[0024] (2) By setting the length of the second positioning post to be shorter than that of the first positioning post, on the one hand, the longer first positioning post can ensure the stability of the sub-clamp when it is installed on the main body. On the other hand, if you want to remove the sub-clamp, lift it from the end where the first positioning post is located. The shorter second positioning post will not hinder the removal of the sub-clamp, making it convenient to remove the sub-clamp. This setting makes it convenient to install the sub-clamp and improve stability, and also convenient to disassemble, thus improving overall efficiency.

[0025] (3) The third positioning post is not on the same side as the first positioning post and the second positioning post. When the sub-clamp moves away from the main body in the direction of the first positioning post and the second positioning post, the sub-clamp will be resisted by the third positioning post, making the sub-clamp more stable when installed on the main body and preventing it from sliding easily.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] Please see Figures 1 to 4 This utility model provides an umbilical cord clamp 10, which includes a main body 100 and a sub-clamp 200. The first side of the main body 100 is provided with a first positioning post 110 and a second positioning post 120 spaced apart. In this embodiment, the first positioning post 110 and the second positioning post 120 are arranged perpendicular to the side of the main body 100. The sub-clamp 200 is provided with a main positioning cavity 210 on one side. The main positioning cavity 210 includes a first positioning cavity 211 and a second positioning cavity 212. The first positioning post 110 and the first positioning cavity 211 cooperate, and the second positioning post 120 and the second positioning cavity 212 cooperate, so that the sub-clamp 200 is installed on the main body 100. By spaced apart the first positioning post 110 and the second positioning post 120, the sub-clamp 200 can be stably installed on the main body 100 and will not fall off due to shaking. The length of the second positioning post 120 is less than the length of the first positioning post 110. When pressure is applied to the sub-clamp 200 from the side of the first positioning post 110 away from the second positioning post 120, the sub-clamp 200 is disengaged from the main body 100.

[0035] Preferably, if the first positioning post 110 and the second positioning post 120 are of the same or similar length, when pressure is applied to the sub-clamp 200 from the side of the first positioning post 110 away from the second positioning post 120, the second positioning post 120 will be stuck in the second positioning cavity 212, preventing the sub-clamp 200 from detaching from the main body 100. By setting the length of the second positioning post 120 to be shorter than that of the first positioning post 110, on the one hand, the longer first positioning post 110 can ensure the stability of the sub-clamp 200 when it is installed on the main body 100; on the other hand, if you want to remove the sub-clamp 200, you can lift it from the end where the first positioning post 110 is located, and the shorter second positioning post 120 will not hinder the removal of the sub-clamp 200, making it convenient to remove the sub-clamp 200. This setting facilitates the installation of the sub-clamp 200, improves stability, and facilitates disassembly, thus improving overall efficiency.

[0036] Preferably, a top plate 140 is provided on the second side of the main body 100 away from the first positioning post 110. In this embodiment, the second side where the top plate 140 is located is perpendicular to the first side of the main body 100. A third positioning post 130 is provided on the top plate 140. The third positioning post 130 is not on the same side as the first positioning post 110 and the second positioning post 120. When the sub-clamp 200 moves away from the main body 100 in the direction of the first positioning post 110 and the second positioning post 120, the sub-clamp 200 will be resisted by the third positioning post 130, so that the sub-clamp 200 is installed... It is more stable on the main body 100 and will not easily slide; the sub-clamp 200 is provided with a secondary positioning cavity 220 that cooperates with the third positioning post 130. When the sub-clamp 200 is installed on the main body 100, the third positioning post 130 is inserted into the secondary positioning cavity 220; when the sub-clamp 200 is disassembled, the end of the sub-clamp 200 away from the first positioning post 110 abuts against the top plate 140, providing a force point for the disassembly of the sub-clamp 200, reducing the lateral force on the first positioning post 110 and the second positioning post 120, thus making disassembly more convenient.

[0037] Specifically, the third positioning post 130 is provided with a first conical guide surface 131; the inner wall of the secondary positioning cavity 220 is provided with a second conical guide surface 221. The first conical guide surface 131 and the second conical guide surface 221 match each other, and the diameter of the first conical guide surface 131 is smaller than that of the second conical guide surface 221 so that the third positioning post 130 has sufficient room for movement in the third positioning cavity.

[0038] Preferably, in order to achieve a balance between stable installation and easy disassembly of the sub-clamp 200, in this embodiment, the diameter of the first positioning post 110 is set to 1.6mm-2.2mm and the length to 4mm-4.5mm; and / or the diameter of the second positioning post 120 is set to 1.5mm-2.0mm and the length to 1.3mm-1.8mm; and / or the root diameter of the third positioning post 130 is set to 1.7mm-2.2mm, the top diameter to 1.1mm-1.6mm, and the length to 2.3mm-2.8mm.

[0039] Furthermore, the distance between the top plate 140 and the second fixed post is 16mm-18mm, and the distance between the second fixed post and the first fixed post is 20mm-22mm. By setting the distance between the first positioning post 110 and the second positioning post 120 and the distance between the second positioning post 120 and the top plate 140, a ratio that makes it easy for the sub-clamp 200 to be disassembled is found, so that the set disassembly route is stable and reasonable.

[0040] In addition, the umbilical cord clamp 10 also includes a push-cutting rod 300. A slide rail 320 is provided on one side of the push-cutting rod 300, and a slide groove 150 that cooperates with the slide rail 320 is provided on the main body 100. The push-cutting rod 300 slides on the main body 100 through the cooperation of the slide rail 320 and the slide groove 150, and the front end of the push-cutting rod 300 cuts into the main body 100 from the end where the first positioning post 110 is located. When pressure is applied to the push-cutting rod 300, the front end of the push-cutting rod 300 can pass through the sliding gap 160 between the sub-clamp 200 and the main body 100, so that the front end of the push-cutting rod 300 cuts the umbilical cord. The push-cutting rod 300 is further pushed. When the push-cutting rod 300 applies pressure to the sub-clamp 200 from the side of the first positioning post 110 away from the second positioning post 120, the sub-clamp 200 is disengaged from the main body 100.

[0041] Preferably, the push-cutting rod 300 is provided with an ejector 310 on the side near the sub-clamp 200. The ejector 310 is located in the middle of the push-cutting rod 300. The ejector 310 needs to be positioned on the push-cutting rod 300 away from the front end to ensure that the push-cutting rod 300 completely cuts the umbilical cord before ejecting the sub-clamp 200. When the ejector 310 moves to the sliding gap 160, the ejector 310 applies a force to the sub-clamp 200 from the main body 100 in the direction of the sub-clamp 200. This first causes the first positioning pin 110 to disengage from the first positioning cavity 211, and then further causes the sub-clamp 200 to disengage from the main body 100.

[0042] Preferably, the ejector 310 has a guide surface 311 on the side near the sub-clamp 200. In order to facilitate the ejector 310 to eject the sub-clamp 200 from the main body 100, a guide surface 311 with a slope is required. The angle of the guide surface 311 relative to the push-cutting rod 300 is 135-140°. Setting a reasonable angle can help to eject the sub-clamp 200 with less effort, while not occupying too much space on the push-cutting rod 300 to affect other components.

[0043] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
