Description

Technical Field

[0001] The utility model relates to the technical field of obstetric medical instruments, in particular to an umbilical cord cutter with the function of detecting pulse pulsation. Background Art

[0002] After birth, the umbilical cord continues to pulsate, and blood continues to exchange between the placenta and the newborn. This period lasts for a while until the newborn's lungs fully open and they begin breathing independently. This brief period is medically known as the fetal-to-neonatal transition period. Over approximately 3-4 minutes, as the alveoli open, the fluid within the lungs (lobes) is absorbed by the circulatory and lymphatic systems, allowing effective breathing to resume. When the partial pressure of oxygen in the blood rises to a certain level, the umbilical artery closes, the umbilical cord pulsation ceases, and thus, physiologically, blood exchange between the placenta and the newborn ceases.

[0003] However, the current clinical practice of using umbilical cord clamps for late cord clamping of infants mainly relies on the doctor's subjective judgment, clinical experience and timer reminders. It is easy for the umbilical cord to be cut too early, resulting in insufficient utilization of the blood in the umbilical cord and failure to maximize the improvement of neonatal ischemia and hypoxia, making it impossible to fully implement "late cord clamping".

A knife groove 106 is provided on the shearing surface 103 of the first scissors body 101, and the blade 105 and the knife groove 106 are in a horizontal line. There is a knife groove 106 below the knife groove 106. Clamping knurl 107, the second scissors 102 is provided with an engaging groove 113 at one end of the shearing surface 103, and a clamping component 112 is embedded in the engaging groove 113. The clamping component 112 is located just below the blade 105 and is in a horizontal line with the clamping knurl 107. The umbilical cord is pre-clamped before the umbilical cord is cut. A motor 108 is fixedly provided at the position between the tail end of the first scissors 101 and the guide groove 104. A gear 109 is provided at the output end of the motor 108. A rack groove 110 is provided at the tail end of one side of the second scissors 102 that is attached to the first scissors 101. The rack groove 110 meshes with the gear 109. The motor 108 is controlled by the timing controller 3, and the timing controller 3 can be used to control the start of the motor 108. The motor 108 drives the second scissors 102 to complete the automatic cutting work. The front end of the umbilical cord cutting assembly 1 is provided with an umbilical cord binding assembly 4. The first scissors 101 is fixedly connected to the detection assembly 2 on the side away from the guide groove 104. The detection assembly 2 includes a detection body 201. The front end of the detection body 201 is an annular detection chuck 202. The annular detection chuck 202 is hinged with a ring buckle 203. In this way, the umbilical cord can be wrapped and fixed. The end of the ring buckle 203 away from the hinge is connected to the detection body 2. 01 is provided with a matching locking knurl 205 at one end facing the annular detection chuck 202, and the locking knurl 205 can complete self-locking after the annular buckle 203 is buckled. A number of sensing probes 204 are provided on the inner wall of the annular detection chuck 202. The sensing probes 204 can transmit the sensing signal to the timing controller 3. The tail ends of the umbilical cord cutting component 1 and the detection component 2 are fixedly connected to the timing controller 3. A buzzer 301 is connected to one side of the timing controller 3. The timing controller 3 starts timing when it receives the pulsation signal transmitted by the sensing probe 204, and turns on the buzzer 301 to emit a prompt sound after the pulsation signal disappears.

[0025] The umbilical cord binding assembly 4 includes an upper binding assembly 4a and a lower binding assembly 4b. The upper binding assembly 4a includes a clamp body buckle 409, an umbilical cord clamp 407 and a clamp body block 408. The clamp body block 408 is provided on the first scissors body 101, just above the clamping knurl 107. The clamp body buckle 409 is provided on the second scissors body 102 near the blade 105. The umbilical cord clamp 407 is buckled into the clamp body buckle 409, with the clamp opening facing the clamp body block 408. The lower binding assembly 4b includes a connecting sleeve 401, the top surface of the connecting sleeve 401 is fixedly connected to the bottom surface of the first scissors body 101, a stop block 402 is provided on one side of the connecting sleeve 401, a support ring 403 is sleeved inside the connecting sleeve 401, and the part of the support ring 403 located below the second scissors body 102 is provided with a tooth flower 404, the bottom surface of the second scissors body 102 is provided with a tooth surface 405 meshing with the tooth flower 404, and a strapping belt 406 is sleeved on the support ring 403.

[0026] The clamping assembly 112 includes a clamping block 112a, and the clamping block 112a has an anti-slip knurled surface 112b on the side facing the clamping knurl 107. A spring 112c is provided between the end of the clamping block 112a away from the anti-slip knurled surface 112b and the engaging groove 113. When the second scissors body 102 is pushed forward, the clamping block 112a contacts the umbilical cord in advance, and the second scissors body 102 presses the clamping block 112a with the spring 112c in the engaging groove 113, so that the clamping block 112a and the clamping knurl 107 pre-clamp the umbilical cord.

[0027] The second scissor body 102 is provided with a pushing knurled surface 111, so that the staff can also complete the umbilical cord cutting work manually when the automatic cutting is not turned on.

[0028] The specific implementation process is as follows:

[0029] After the newborn is delivered, the medical staff places the baby's umbilical cord scissors at the umbilical cord cutting site, and passes the umbilical cord through the shearing surface 103 of the first shearing body 101 and the shearing surface 103 of the second shearing body 102, and passes through the annular detection head 202 of the detection assembly 2. The medical staff buckles the annular buckle 203, and the locking knurling of the annular buckle 203 and the detection body 201 complete self-locking. At this time, the sensing probe 204 in the annular detection chuck 202 monitors the umbilical cord pulsation and transmits the pulsation signal to the timing controller 3. At this time, the timing control starts to time the pulsation of the baby's umbilical cord. When the pulsation stops, the timing controller 3 receives a stop signal and automatically turns on the buzzer 301 to emit a prompt sound to remind the medical staff. At the same time, the timing controller 3 automatically turns on the motor 108. The motor 108 rotates and drives the second shearing body 102 to move forward through the engagement of the gear 109 and the rack groove 110. The first shearing body 101 and the second shearing body 102 are engaged. The clamping assembly 112 cooperates to pre-clamp the umbilical cord, and the umbilical cord is cut by the blade 105. After cutting, the blade 105 cuts into the knife groove 106 of the first scissors 101. At the same time as cutting, the second scissors 102 drives the support ring 403 of the umbilical cord binding assembly 4 to rotate through the engagement of the tooth surface 405 and the tooth flower 404. The rotation of the support ring 403 is carried out simultaneously with the umbilical cord cutting work. When the umbilical cord cutting is completed, the support ring 403 rotates to the umbilical cord cutting assembly 1 When the second scissors body moves forward, the upper end tying assembly moves forward, and the umbilical cord clamp contacts the clamp body tack block. When the second scissors body moves forward, the clamp body tack block pushes out the umbilical cord clamp. After the umbilical cord clamp pops out of the clamp body buckle, the clamp mouth closes and tightens the upper end of the umbilical cord to complete the tying of the upper end of the umbilical cord. After the tying is completed, the medical staff removes the umbilical cord scissors to complete the umbilical cord cutting work for the baby.
