DETAILED DESCRIPTION

[0036] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] Example:

[0038] like Figure 1-6 As shown; a clamping sleeve device for an umbilical cord, comprising two clamp bodies 60 hinged by a hinge shaft 9, the upper half of the clamp body 60 is provided with a jaw 61, the lower half of the clamp body 60 is a handle 62, an umbilical cord clamp 63 for clamping the umbilical cord is located between the two clamp bodies 60, and two umbilical cord clamps 63 are provided, and the two umbilical cord clamps 63 are symmetrically arranged on both sides of the jaw 61; the distance between the two umbilical cord clamps 63 is 25mm~30mm; in this embodiment, the distance between the two umbilical cord clamps 63 is 30mm.

[0039] The jaws 61 are provided with a squeezing block 64 for squeezing blood in the umbilical cord; an inner groove 65 is formed in the squeezing block 64, and the umbilical cord clamp 63 is assembled in the inner groove 65; specifically, the inner side surfaces of the two clamp arms 63-1 of the umbilical cord clamp 63 are provided with a mutually locking structure, wherein the two clamp arms 63-1 are in an arc-shaped structure, which can make the contact area larger and the force more balanced during the clamping action of the umbilical cord clamp 63, so that the clamping effect of the umbilical cord clamp 63 is better, and the clamping stability and safety are improved; the mutually locking structure can be a locking structure formed by the rack 14 and the tooth hole 15 meshed with the rack, or a locking structure formed by the ratchet hook and the ratchet hook groove, or a locking structure formed by the combination of the two; in this embodiment, the tooth meshing structure is preferably used together with the ratchet hook and the ratchet hook groove structure. The fixed locking structure at the head end of the umbilical cord clamp can strengthen the tooth meshing, which can effectively prevent the possibility of the umbilical cord clamp falling off when fixed, and the closure is tighter, which can effectively prevent the umbilical cord clamp from falling off due to the baby's movements or other movements.

[0040] When in use, when the two handles 62 are closed, the two sides of the squeezing block 64 first abut against the umbilical cord that needs to be clamped, and the squeezing block 64 limits the umbilical cord in contact with it. The squeezing block 64 is used to squeeze the blood of the umbilical cord between the two umbilical cord clamps 63. At the same time, the racks and tooth holes on the umbilical cord clamp 63 are also used to limit the movement of the umbilical cord. When the squeezing blocks 64 on both sides are completely closed, the racks and tooth holes on the umbilical cord clamp 63 are engaged with each other, and the umbilical cord clamp 63 is used to clamp the umbilical cord. The umbilical cord clamp 63 is locked by its mutually locking structure; after the umbilical cord clamp 63 completes clamping, the handle 62 is used to open the clamp body 60, and the umbilical cord clamp 63 is disengaged from the jaws 61.

[0041] A connecting column 90 is fixedly provided at the bottom of the umbilical cord clamp 63, and an umbilical cord sleeve mechanism 70 is installed on the connecting column 90. Correspondingly, a mounting hole 80 for the umbilical cord sleeve mechanism 70 to pass through is formed on one side of the clamp body 60. The present invention fixes a connecting column at the bottom of the umbilical cord clamp, and an umbilical cord sleeve mechanism is installed on the connecting column. After the umbilical cord is clamped by the saw teeth, the umbilical cord ligating ring can be sleeved on the umbilical cord through the umbilical cord sleeve mechanism, thereby improving the operating efficiency and saving the use cost.

[0042] Specifically, the connecting column 90 includes a column body 91 and a limiting cap 92. The limiting cap 92 is fixedly mounted on the top of the column body 91, and the bottom of the column body 91 is fixedly mounted on the umbilical cord clamp 63. In addition, the outer diameter of the column body 91 is smaller than the outer diameter of the limiting cap 92. The column body 91, the limiting cap 92 and the umbilical cord clamp 63 are fixedly connected and integrally formed, thereby improving the structural strength and overall firmness of the entire umbilical cord clamp 63, thereby ensuring safe use.

[0043] The umbilical cord sleeve mechanism 70 includes a ring body 1, a clamping hole 3 for clamping the umbilical cord is formed in the middle of the ring body 1; a pull wire 6 passes through the clamping hole 3, and the pull wire 6 is connected to the operating handle 2; the ring body 1 is sleeved on the column body 91 of the connecting column 90.

[0044] During use, after the saw teeth clamp the umbilical cord, the pull wire 6 is pulled to stretch the clamping hole 3 to expand the ring body 1; the expanded ring body 1 is put over the entire umbilical cord clamp 63, and then is connected to the baby's umbilical cord. The two ring bodies 1 are respectively connected to the baby's umbilical cord and are located between the two umbilical cord clamps 63. One of the ring bodies 1 is put on the root of the baby's umbilical cord. The pull wire 6 pulls the ring body 1 from the umbilical cord clamp 63 to the baby's belly, and the pull wire 6 is pulled to adjust the ring body 1 so that the ring body 1 fits the root of the baby's umbilical cord. The two ring bodies 1 are set to avoid damage to one of the ring bodies during use. After the connection is completed, the pull wire 6 is released so that the clamping hole 3 of the ring body 1 is used to clamp the umbilical cord; to prevent the baby from being infected with bacteria during growth; after the ring body 1 completes the entire connection process, it is convenient for the doctor to cut the umbilical cord, which is convenient and safe.

[0045] Multiple anti-slip strips 4 are arranged on both sides of the operating handle 2 along its length direction; the multiple anti-slip strips 4 are arranged equidistantly, and the anti-slip strips 4 are used to prevent the operator from slipping when pulling the pull wire 6. The problem that the umbilical cord sleeve mechanism 70 is easy to slip under the stress of hand grip during use is effectively overcome.

[0046] The width of the operating handle 2 is smaller than the width of the mounting hole 80; in this way, after the clamp body 60 completes the process of clamping the umbilical cord, the mounting hole 80 on the clamp body 60 can smoothly pass through the umbilical cord sleeve mechanism 70, the clamp body 60 is separated from the umbilical cord clamp 63, and the umbilical cord sleeve mechanism 70 is located on the umbilical cord clamp 63, which provides convenience for the subsequent sleeve connection of the umbilical cord.

[0047] The length of the ring body 1 is consistent with the height of the column body 91 ; thus, the entire ring body 1 can be completely clamped between the limiting cap 92 and the clamp body 60 , avoiding the risk of the ring body 1 falling off the connecting column 90 .

[0048] The ring body 1 is sleeved on the column body 91, and the outer side of the ring body 1 is on the same horizontal plane as the outer side of the limiting cap 92; the risk of the ring body 1 falling off the connecting column 90 is avoided, and the flexibility and safety of use are increased.

[0049] The overall structure of the ring body 1 is compact and the design is ingenious, wherein the inner diameter of the ring body 1 is 1.4mm~1.6mm; the outer diameter of the ring body 1 is 3.5mm~4.0mm; the length of the ring body 1 is 2.5mm~4.0mm; specifically, in this embodiment, the inner diameter of the ring body 1 is 1.5; the outer diameter of the ring body 1 is 3.8mm; and the length of the ring body 1 is 3.0mm.

[0050] The ring body 1 is made of a flexible elastic material; wherein the flexible elastic material is rubber or medical silicone, which has good elasticity and high strength of plastic; it can directly contact with infants and young children, and facilitates stability and safety after clamping the umbilical cord.

[0051] The periphery of the ring body 1 is an arc transition structure, which increases the contact area between the ring body and the baby's skin during use of the umbilical cord ligation ring, avoids scratches on the baby's skin by conventional spikes, and further ensures safety in use.

[0052] Meanwhile, the pull wire 6 is a cotton wire or a plastic wire. In the present embodiment, the pull wire 6 is a cotton wire, which improves the strength of the pull wire 6 and ensures its safety in use.

[0053] Among them, the umbilical cord clamp 63 is a conventional umbilical cord clamp, but it is 10mm to 15mm shorter than the existing umbilical cord clamp. The outer side of the umbilical cord clamp is relatively smooth. During use, the umbilical cord clamp 63 located in the inner groove 65 is deformed quickly and reliably through the pressing of the clamp body 60, and is used to clamp the umbilical cord. After clamping the umbilical cord, the clamp body 60 is separated from the umbilical cord clamp, and then the umbilical cord is cut from the middle of the two umbilical cord clamps 63 with operating room scissors. In this way, the umbilical cords on both sides of the two umbilical cord clamps 63 will not bleed, and the operation is simple and the effect is reliable.

[0054] The extrusion block 64 is made of a high-rebound material; the high-rebound material is made of one of a silicone layer, an EVA material layer, a phylong material layer, a PU material layer, a TPU material layer or a foam material layer; more specifically, in the present embodiment, the high-rebound material is a sponge, which has the advantages of better resilience, longer service life and better wrapping. The sponge can be bonded to the jaws 61 of the clamp body 60, and has the advantage of being more stable in removing umbilical cord blood.

[0055] A limiting protrusion 68 is arranged on the top of one side of the jaw 61, and correspondingly, a limiting groove 69 is arranged on the top of the other side of the jaw 61; when the limiting protrusion 68 is assembled in the limiting groove 69, the umbilical cord clamp 63 is used to clamp the umbilical cord; the limiting protrusion 68 and the limiting groove 69 are located between the two umbilical cord clamps 63, wherein two limiting protrusions 68 and two limiting grooves 69 are provided.

[0056] In order to improve the overall holding stability of the clamping device of the umbilical cord clamp during use, the present embodiment makes improvements on the handle 62. A plurality of anti-skid patterns 66 are provided on the two handles 62 of the clamp body 60 along the length direction thereof; the plurality of anti-skid patterns 66 are arranged equidistantly on the handle 62, and a limit block 67 is arranged on the top of the anti-skid pattern 66. The limit block 67 is used to prevent the handle 62 from loosening, and the anti-skid pattern 66 prevents the handle 62 from slipping. The combined use of the limit block 67 and the anti-skid pattern 66 effectively overcomes the problem that the clamping device is easy to slip under the stress of the hand grip during use.

[0057] The handle 62, the anti-slip pattern 66 and the limit block 67 are fixedly connected and integrally formed, thereby improving the structural strength and overall firmness of the entire clamp body 60 and further ensuring the safety of use. At the same time, since the present invention is a medical device, all components are made of medical materials, preferably medical transparent materials, during production and manufacturing.

[0058] The present invention has a simple structure and an ingenious design. A squeezing block is arranged in the jaws, and the squeezing block is used to squeeze the blood in the umbilical cord. Before the umbilical cord clamp is used to clamp the umbilical cord, the blood in the umbilical cord between the two umbilical cord clamps is emptied by the squeezing block, and then the umbilical cord is clamped by the two umbilical cord clamps. In this way, no blood will flow out of the umbilical cord, thereby avoiding the transmission of blood-borne diseases and improving safety performance.
