Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a tourniquet for the femoral artery and vein puncture point after interventional treatment for congenital heart disease in children. Background Technology

[0002] Congenital heart disease is a congenital malformation caused by abnormal development of the heart and great vessels during embryonic development. Its incidence rate is 6‰–10‰ of live births, ranking first in both incidence and mortality among major birth defects in my country. There are various methods for applying pressure to the puncture site after interventional procedures for congenital heart disease. Manual pressure can be applied at a force of 2-3 kg for about 2 hours. While economical and controllable, this method is labor-intensive and requires a high level of skill from the person applying the pressure. Alternatively, a regular bandage or wide adhesive tape can be used, with manual pressure applied after hemostasis. However, adhesive products can easily cause skin damage, allergies, pain, and increase the risk of infection. A 0.5-1 kg saline bag or sandbag can also be used to apply pressure for 6-12 hours, but this can be dislodged due to the child's agitation. Some arterial compression devices are made of hard materials, which can easily cause skin damage, and some are expensive, increasing the patient's medical costs.

[0003] The patent published under announcement number "CN213249479U" is titled "A Pressure-Adjustable Femoral Artery and Vein Hemostatic Bandage." While the device in this document allows for control of the hemostatic force, children with congenital heart disease are naturally active. When their lower limbs are unconsciously and repeatedly bent, the hemostatic device can easily become misaligned with the puncture point, affecting the hemostatic effect. Furthermore, when a child's lower limbs remain in the same position for a long time, poor blood circulation can easily lead to numbness, causing the child to become irritable and resistant to treatment. Therefore, this utility model designs a hemostatic bandage for the femoral artery and vein puncture point after interventional procedures for congenital heart disease in children to solve the above problems.

[0025] Example 1

[0026] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the device includes an air cushion 1, a first strap 2, and a mounting plate 3. The first strap 2 is fixed to the bottom left side of the air cushion 1, and the mounting plate 3 is fixed to the top middle of the air cushion 1. An exhaust assembly 4 is provided on the outer wall of the mounting plate 3. The exhaust assembly 4 includes a pump 401 fixed to the top middle of the mounting plate 3. A soft material shaped tube 402 is fixed to the top of the pump 401. A first valve 403 is rotatably passed through the outer left side of the shaped tube 402. A hemostatic assembly 5 is provided inside the first strap 2. The hemostatic assembly 5 includes... The first airbag 501 is fixedly installed on the left and right sides inside the first set 2. A connecting tube 502 of soft material is fixedly installed at the upper end between each pair of the first airbag 501. The first airbag 501 on the left side is fixedly sleeved on the outer left side of the shaped tube 402. A connecting strip 503 is fixedly installed at the lower end between each pair of the first airbag 501. A connecting plate 504 is fixedly installed at the top of the connecting strip 503. A sponge pad 505 is attached to the top of the connecting plate 504 by Velcro. Heating pads 506 are fixedly installed at both the front and rear ends inside the first set 2.

[0027] The connecting tube 502 is designed to be connected to the interior of the first airbag 501. The connecting strip 503 and the connecting plate 504 are made of rubber. Medical staff first place the first set of airbags (with two straps) over the child's thigh area, ensuring the sponge pad 505 aligns with the femoral artery puncture site. Then, they activate the inflation function of the pump 401, releasing gas through the tube 402 into the first airbag 501. The connecting tube 502 connects the interiors of the two first airbags 501, causing both airbags 501 to inflate simultaneously. The inflated first airbags 501 then move the connecting strip 503 and the connecting plate 504 together. 4. The sponge pad 505 applies pressure to the puncture site area of ​​the child to stop bleeding. Once the pressure applied by the first airbag 501 and the sponge pad 505 to the puncture site meets the needs of the medical staff, the medical staff can then turn off the pump 401 and the first valve 403 in sequence. Depending on the actual use, the medical staff can use the heating pad 506 to apply heat to the puncture site area of ​​the child, thereby improving the blood circulation of the child's lower limbs.

[0028] Example 2

[0029] like Figure 1 , Figure 3 As shown, a soft material mounting tube 6 is fixedly inserted through the top left side of the air cushion 1. The mounting tube 6 passes through the irregular tube 402. A second valve 7 is rotatably inserted through the outside of the mounting tube 6. A second sleeve 8 is fixedly installed on the bottom right side of the air cushion 1. A second airbag 9 is fixedly installed inside the second sleeve 8. The second airbag 9 is fixedly sleeved on the outside right side of the irregular tube 402. Several vibrators 10 are fixedly installed inside the second airbag 9. The vibrators 10 are flat micro vibration motors. A third valve 11 is rotatably inserted through the outside right side of the irregular tube 402. A controller 12 is fixedly installed on the top right side of the mounting plate 3. The controller 12 is connected to the heating pad 506, the pump 401 (both for pumping and discharging), and the vibrators 10 via wires. A detachable lithium battery 13 is installed on the inside left side of the mounting plate 3. The lithium battery 13 is connected to the controller 12 via wires.

[0030] According to the operation method in Embodiment 1, when the temperature of the heating pad 506 reaches the value set by the controller 12, the heating pad 506 stops working. After the medical staff puts the first set of straps 2 on the child's thigh, they then put the second set of straps 8 on the child's calf. After the first airbag 501 has fully inflated and the first valve 403 is closed, the medical staff opens the second valve 7 and then starts the inflation function of the pump 401, so that the inflation gas is discharged into the airbag 1 through the installation tube 6, that is, the airbag 1 inflates. When the airbag 1 is inflated to the level required by the medical staff, the medical staff first closes the pump 401 and the second valve 7 in sequence, then opens the third valve 11, and then starts the inflation function. The pump 401 inflates, and the gas is discharged into the second airbag 9 through the tube 402. The inflated second airbag 9 is firmly connected to the child's lower leg. Once the inflated state of the second airbag 9 meets the needs of the medical staff, the medical staff will then turn off the pump 401 and the third valve 11 in sequence. In this way, the inflated airbag 1 restricts the bending of the child's lower limb, thereby immobilizing the child's lower limb and preventing the sponge pad 505 from being misaligned with the puncture point due to repeated bending. In addition, the medical staff can turn on the vibrator 10. The vibration generated by the vibrator 10 massages the child's lower leg, further improving the blood circulation of the child's lower limb.
