Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to an auxiliary device for delivering newborns. Background Art

[0002] The umbilical cord is the main channel for the fetus and the mother to "communicate" with each other. It delivers nutrients to the fetus through the umbilical vein and brings waste to the mother through the umbilical artery, which is then excreted by the mother. After the fetus is born, the doctor will tie the umbilical cord, and the newborn will be "separated" from the mother and become an independent person. After the umbilical cord is cut, a wound is formed, which is an important portal for bacteria to invade the newborn's body. In mild cases, it can cause omphalitis, and in severe cases, it often leads to sepsis and death. Therefore, the umbilical cord cutting tool used in the delivery of newborns is very important.

[0003] For cutting the umbilical cord, a patent application with application number CN2643843Y discloses an "umbilical cord cutter", which is composed of a valve, an umbilical cord clamp, and a fixed frame. A cutting blade is fixed to the middle of the rear end of the fixed frame, and the front end of the fixed frame is open. There is a groove-shaped channel on each side of the fixed frame in which the valve and the umbilical cord clamp can slide respectively, and there is a slide on the upper and lower inner sides of the groove-shaped channel, and there is a notch at the rear end of the groove-shaped channel for sliding the umbilical cord clamp; there is a handle at the front end of the valve, and an elastic clamp with elasticity at the rear end, and the inner side of the elastic clamp is serrated, and the upper and lower sides of the valve are respectively provided with grooves matching the slide; the umbilical cord clamp is an elastic clamp with elasticity, and the inner side is serrated, and the upper and lower sides of the umbilical cord clamp are respectively provided with grooves matching the slide, and the front end of the umbilical cord clamp is provided with a bayonet for clamping the umbilical cord clamp. Under ideal conditions, the umbilical cord cutter can complete the ligation and cutting of the umbilical cord in one go, and the medical staff can avoid touching the umbilical cord of the newborn, which can reduce the probability of umbilical cord infection in the newborn and the health risks of the medical staff. However, since the cutting function of the umbilical cord cutter is unreliable and the umbilical cord itself has a certain toughness, there is a hidden danger of repeatedly cutting the umbilical cord, which will inevitably pull the umbilical cord and cause unnecessary harm to the newborn.

The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0037] See also Figure 1-5 The present invention provides a technical solution: an auxiliary device for neonatal delivery, comprising a shearing portion, wherein the shearing portion comprises an upper shearing blade 1 and a lower shearing blade 101 which are rotatably connected at one end, and also comprises a mounting seat 2 connected to the lower shearing blade 101, and the mounting seat 2 is also slidably connected;

[0038] The first clamping plate 4 has a width smaller than that of the second clamping plate 401 and has a top surface for supporting a slider 201 of the umbilical cord. The slider 201 can slide along the length direction of the lower shearing blade 101, and the top surface of the slider 201 is transversely offset from the cut surface of the lower shearing blade 101.

[0039] The mounting seat 2 is provided with a driving part for driving the slider 201 to slide, and the driving part includes a rack 2011 connected to the slider 201 and a gear 2012 that is coaxial with and connected to the rotating parts of the upper shearing blade 1 and the lower shearing blade 101. The gear 2012 extends along the length direction of the slider 201, and the top surface of the gear 2012 is meshed with the bottom surface of the gear 2012.

[0040] In this solution, the upper shearing edge 1 and the lower shearing edge 101 have a blade on one side opposite to the other, and the two are connected by rotation at one end to form a scissor-like structure, and the two can cut the umbilical cord when they are relatively close to each other by rotation;

[0041] When in use, the operator applies force to press the upper shearing blade 1 or the lower shearing blade 101 to cause the two to move relative to each other, thereby reducing the distance between the two, so as to cut the umbilical cord by bringing the two relatively close to each other;

[0042] When the upper shearing blade 1 and the lower shearing blade 101 are relatively close, the rotating part between the two rotates to drive the gear 2012 to rotate synchronously in the same direction. Since the rack 2011 is meshed with the bottom surface of the gear 2012, the rack 2011 drives the slider 201 to slide (the specific connection method between the gear 2012 and the rack 2011 can be referred to Figure 4 ). When the gear 2012 rotates in the counterclockwise direction, the rack 2011 is affected by the gear 2012 to move in the direction close to the gear 2012. That is, the rack 2011 drives the slider 201 to move toward the connection part of the upper shearing blade 1 and the lower shearing blade 101.

[0043] During the above process, when the upper shearing blade 1 and the lower shearing blade 101 are relatively close to each other to cut the umbilical cord on the slider 201, the slider 201 drives the umbilical cord to move toward the connection between the upper shearing blade 1 and the lower shearing blade 101. At this time, the umbilical cord is in a moving state and contacts with the blades of the upper shearing blade 1 and the lower shearing blade 101, which increases the friction between the umbilical cord and the upper shearing blade 1 and the lower shearing blade 101, so as to facilitate the cutting of the umbilical cord and reduce the situation where the umbilical cord needs to be cut repeatedly due to the insufficient sharpness of the upper shearing blade 1 and the lower shearing blade 101.

[0044] In this embodiment, it also includes an upper support plate 3 and a lower support plate 301 connected to the upper shearing blade 1 and the lower shearing blade 101 respectively, and the upper shearing blade 1 and the lower shearing blade 101 are located on the opposite side of the upper support plate 3 and the lower support plate 301;

[0045] The upper support plate 3 and the lower support plate 301 are provided with elastic rings 302 at opposite ends, and one side of the elastic ring 302 is provided with an opening, and one end of the upper shearing blade 1 and the lower shearing blade 101 are respectively connected to the two ends of the opening.

[0046] Among them, the elastic ring 302 can be made of spring steel or elastic plastic. In the natural state, the two ends of the upper support plate 3 and the lower support plate 301 are installed to remain unfolded in a relatively distant direction under the action of elasticity, and the upper support plate 3 and the lower support plate 301 are connected by the elastic ring 302 to form a whole.

[0047] When in use, the operator places the thumb on the top surface of the upper support plate 3, and the other fingers can lift the bottom surface of the lower support plate 301, and press the upper support plate 3 with the thumb to make the upper support plate 3 and the lower support plate 301 relatively close to each other, so as to cut the umbilical cord. In this process, the elastic ring 302 is elastically extended under the influence of the pressing, and when the external force is lost, the elastic ring 302 is restored under the elastic action, that is, the upper support plate 3 and the lower support plate 301 are relatively expanded. In this way, the umbilical cord is cut by the cooperation of the elastic ring 302, the upper support plate 3 and the lower support plate 301, and the cutting structure is simple and the production cost is low.

[0048] In this embodiment, two first clamping plates 4 and two second clamping plates 401 are respectively provided on opposite sides of the upper support plate 3 and the lower support plate 301, and the upper shearing edge 1 and the lower shearing edge 101 are respectively located between the two first clamping plates 4 and the two second clamping plates 401.

[0049] Among them, the area where the two first clamping plates 4 and the two second clamping plates 401 are located is the two clamping areas, the area where the slider 201 is located is the supporting area for supporting the umbilical cord, the two clamping areas are respectively located on both sides of the supporting area, and the upper shearing blade 1 and the lower shearing blade 101 cut the umbilical cord in the supporting area.

[0050] During specific use, the upper support plate 3 and the lower support plate 301 are close to each other to cut the umbilical cord through the upper shearing blade 1 and the lower shearing blade 101, while the first clamping plate 4 and the second clamping plate 401 are also relatively close to each other to squeeze and clamp the umbilical cord, so as to maintain the stability of the umbilical cord during cutting and promote the closure of the umbilical cord blood vessels by squeezing and clamping the umbilical cord, thereby preventing excessive bleeding during cutting.

[0051] In this embodiment, an elastic sheet 5 coaxial with the elastic ring 302 is provided at one end of the mounting seat 2, and a rotating shaft 501 extending along the thickness direction of the mounting seat 2 is provided on a side of the elastic sheet 5 facing the elastic ring 302, and the rotating shaft 501 has a diameter no greater than the diameter of the elastic ring 302, and the rotating shaft 501 is coaxially connected to the gear 2012;

[0052] A limiting block extending along the diameter direction of the elastic ring 302 is arranged on the inner wall of the elastic ring 302 , and a limiting groove for inserting the limiting block is arranged on one side of the rotating shaft 501 , and the limiting groove passes through a side of the rotating shaft 501 away from the elastic sheet 5 .

[0053] The elastic sheet 5 is made of elastic materials such as spring sheets and elastic plastics, and its lower end is connected to the mounting seat 2 and is located on one side of the elastic ring 302 . The operator can pull the elastic sheet 5 to move its upper end away from the elastic ring 302 .

[0054] During specific use, the operator can pull the elastic sheet 5 away from the elastic ring 302 until the shaft 501 is out of the elastic ring 302, and then the operator can remove the upper support plate 3 and the lower support plate 301 to replace or clean the upper shear blade 1 and the lower shear blade 101 on the upper support plate 3 and the lower support plate 301. Similarly, the operator can pull the elastic sheet 5 away from the elastic ring 302, and then install the upper support plate 3 and the lower support plate 301 on the mounting seat 2, and then release the elastic sheet 5, so that the shaft 501 is inserted into the elastic ring 302, and the slot 5012 and the insert block 3021 are connected.

[0055] In this embodiment, a blocking piece 6 is provided at the opening of the elastic ring 302 , and the blocking piece 6 is connected to the inner wall of the elastic ring 302 . The opening is located on the rotation track of the blocking piece 6 .

[0056] During specific use, the upper support plate 3 is pressed to cause the upper support plate 3 and the lower support plate 301 to rotate. When the distance between the two is shortened, the baffle 6 is pressed as the upper support plate 3 is pressed and rotates synchronously in the elastic ring 302, causing the baffle to cover the open part of the elastic ring 302. When the umbilical cord is cut, it is less likely to slide into the elastic ring 302 due to the inertia generated by the sliding of the slider 201, so that the umbilical cord cutting step can be better completed.

[0057] In this embodiment, the top surface of the mounting seat 2 is provided with a fixing groove 7 extending along the length direction of the lower shearing blade 101, and a fixing block 701 is slidably fitted in the fixing groove 7. The fixing block 701 is connected to the bottom surface of the lower support plate 301. The lower support plate 301 can be slidably fitted with the mounting seat 2 through the fixing groove 7 and the fixing block 701.

[0058] During specific use, when installing the lower support plate 301, after pulling the elastic sheet 5 away from the elastic ring 302, the operator first inserts the lower support plate 301 into the fixing groove 7 through the fixing block 701 for fixing, and then slides the lower support plate 301 to align the elastic ring 302 and the elastic sheet 5. At this time, the operator releases the elastic sheet 5 to fix the upper support plate 3 and the lower support plate 301. In this state, the lower support plate 301 is fixed as a whole with the mounting seat 2 to enhance the fixing effect of the lower support plate 301 and the mounting seat 2.

[0059] In this embodiment, two slide grooves extending along the width direction of the mounting seat 2 are provided on one side of the upper support plate 3 close to the lower support plate 301, and the two first clamping plates 4 are slidably connected to the upper support plate 3 through the two slide grooves respectively;

[0060] The width of the first clamping plate 4 is smaller than the width of the second clamping plate 401 .

[0061] During specific use, the operator can adjust the distance between the two first clamping plates 4 so as to clamp and cut the umbilical cords of different infants to the appropriate lengths when some family members need to take the umbilical cord away.

[0062] In this embodiment, the top surface of the upper support plate 3 is rotatably connected to a roller 8, and the two planes of the roller 8 are respectively facing the two first clamping plates 4. The roller 8 is coaxially connected to a transmission rod 801, and at least one end of the transmission rod 801 is provided with a thread and the end is threadedly connected to one of the upper support plates 3.

[0063] During specific use, when the operator presses the upper support plate 3 with his thumb, he can push the roller 8 to rotate with his thumb, and then drive the transmission rod 801 to rotate through the roller 8. Since the transmission rod 801 is threadedly connected to at least one of the upper support plates 3, the upper support plate 3 is prompted to slide along the length direction of the transmission rod 801, so as to adjust the distance between the two upper support plates 3.

[0064] In this embodiment, both ends of the transmission rod 801 are respectively provided with threads with opposite spiral directions, and both ends of the transmission rod 801 are respectively threadedly connected to the two first clamping plates 4 .

[0065] During specific use, since the two ends of the transmission rod 801 are respectively threadedly connected to the two first clamping plates 4 through opposite threads, when the roller 8 rotates, the two first clamping plates 4 slide in opposite directions through the influence of the transmission rod 801, thereby adjusting the distance between the two first clamping plates 4.

[0066] In this embodiment, the top surface of the sliding block 201 is provided with an anti-skid sheet 9 , and the top surface of the anti-skid sheet 9 is provided with anti-skid patterns.

[0067] The anti-skid sheet 9 and the anti-skid pattern can be made of the same material as the roller 8 or rubber material;

[0068] In specific use, when the umbilical cord is cut, the friction between the anti-slip texture slider 201 and the umbilical cord increases the stability of the umbilical cord during cutting, making it difficult for the umbilical cord to escape from between the upper cutting blade 1 and the lower cutting blade 101 during cutting.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
