Description

Technical Field

[0001] The utility model relates to the technical field of medical plaster, in particular to a plaster fixing pad. Background Art

[0002] Plaster fixation is one of the external fixation methods in orthopedics. At present, the application technology of plaster fixation is very mature, but there are still defects. First of all, the elasticity of plaster fixation is small, and it becomes a hard shell after fixation. When the muscle contracts, the plaster shell cannot move with the limb. Although it is suitable when it is made, when the early swelling subsides or the muscles atrophy in the late stage, there will be a certain gap between the plaster and the limb, and the fracture is often displaced in the plaster. Secondly, in order to ensure the stability of the injured area, a review and plaster replacement are required every week. The fracture ends are prone to displacement during the secondary fixation process, affecting recovery. Finally, the pressure on the early injured area after the plaster is formed will cause excessive pressure due to the drooping of the affected limb, causing osteofascial compartment syndrome.

[0003] After searching, the Chinese patent announcement number is CN215459083U, which discloses a plaster fixation internal intelligent pressure control cushion device. In this patent, the pressure on the patient's hand is detected by a pressure sensor, and the pressure value is displayed on a display screen, so that the patient and medical staff can know the pressure value on the patient's hand in real time, and cooperate with a micro air pump to reduce and add air to the soft air cushion accordingly to prevent the patient's hand from being over-pressured and causing osteofascial compartment syndrome. In addition, the corresponding reduction and addition of air to the soft air cushion can promote the patient's hand to fit closely with the plaster, and prevent the gap between the plaster and the hand from causing hand fractures and dislocations when the patient's early swelling subsides or the muscle atrophy occurs in the late stage, which indirectly avoids the frequent replacement of the plaster due to the mismatch between the plaster and the hand size, avoids secondary injuries to the patient, and helps to improve the patient's recovery.

[0004] However, when the above device is in use, it can be seen from the patent drawings that the pressure sensor and the soft air cushion cannot fit tightly against the patient's fracture at the same time, which can easily lead to inaccurate pressure detection values ​​or obstruction of the expansion of the soft air cushion. At the same time, the lengths of the first connecting strap and the second connecting strap cannot be adjusted, making the overall device difficult to use for patients of different age groups, so that the overall device has poor practicality.

A torsion spring 12 is fixedly installed on the outer surface of the round rod 11. The outer surface of the round rod 11 A reel 13 is movably installed on the surface through a torsion spring 12, and the outer surface of the round rod 11 is connected to the inner wall of the reel 13 through the torsion spring 12, so that when in use, under the action of an external force, the reel 13 rotates and the torsion spring 12 is compressed. After the external force disappears, the reel 13 automatically rotates in the opposite direction and resets by utilizing the elastic force of the torsion spring 12. A connecting belt 14 is wound around the outer surface of the reel 13, and a clamping block 15 is fixedly installed on the other side of the right connecting belt 14.

After the pressure detector 5 detects the pressure data when used, the data is transmitted to the controller contained in the control block 6 through the wire 3, and then transmitted to the display screen 8 by the controller and displayed on the display screen 8. When the pressure data is too high, the controller controls the inflation device contained in the inner cavity of the control block 6 to start, and inflate the inner cavity of the air cushion 4 through the connecting tube 2, so that the air cushion 4 expands until the data detected by the pressure detector 5 is normal.

[0028] In summary, compared with general similar devices, this plaster fixation pad has the advantages of improving the accuracy of pressure detection values ​​and being effectively suitable for patients of different age groups.
