Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an adjustable device for treating post-burn hypertrophic scars. Background Art

[0002] Scar is a general term for the appearance and histopathological changes of normal skin tissue caused by various traumas. It is an inevitable product of the human body's trauma repair process. When scar growth exceeds a certain limit, various complications will occur, such as destruction of appearance and functional activity disorders, which will bring great physical and mental pain to patients. Scars left over from burns, scalds, and severe trauma are especially common in the current treatment process. Pressure therapy is often used to reduce the blood supply to scar tissue and reduce excessive synthesis of collagen, thereby inhibiting scar thickening.

[0003] After searching, the Chinese invention patent, publication number: CN116831891A, named: A scar treatment device, the invention works by driving motor 2, the output shaft of motor 2 drives the cam to rotate, and the protruding part of the cam squeezes the two blocks during the rotation, and the two blocks move away from each other and squeeze the two piston cylinders, and the piston cylinder injects gas into the cylinder and the airbag through the air guide tube. The airbag expands and fits tightly with the scar, so as to continuously apply pressure to the scar. When the protruding part of the cam breaks away from the block, the elastic force of spring 2 supports the two blocks to move closer to each other, and the piston cylinder can extract the gas in the cylinder through the air guide tube. At this time, the airbag returns to its original shape, thereby reducing the pressure applied by the airbag on the scar, and so on and so forth, it can achieve the purpose of dynamic pressurization of the scar on the patient's back, abandoning the traditional static pressurization method, which is beneficial to the blood circulation of the limbs, reduces body edema and congestion, and thus improves the treatment effect of the scar.

[0004] However, in actual use, the above and similar technical solutions still have some problems:

[0005] 1. In scenarios where medical treatment equipment is frequently used, with a large daily patient flow, the airbag of the equipment needs to be cleaned after each use. However, the existing cleaning processes such as wiping and disinfection are relatively complex and time-consuming, which increases the burden on operators and prolongs the waiting time for equipment, which is not conducive to improving the overall efficiency of diagnosis and treatment. For scars on the side of the body, the airbag is not easy to accurately contact, and the patient needs to adjust his posture to cooperate. The patient may feel uncomfortable when the treatment is done sideways.

[0006] 2. During balloon compression therapy, ointment is often applied to enhance the therapeutic effect. However, manual application is inconvenient and difficult to ensure uniformity. In addition, the ointment decreases with pressure and absorption during treatment. Reapplication during treatment requires interruption of treatment, affecting the continuity and effectiveness of treatment.

[0007] 3. Currently, scar treatment relies solely on pressure, which is a single method and has limited effect on promoting scar softening. The equipment lacks an auxiliary knocking mechanism and cannot accelerate the scar softening process through physical stimulation, which limits the further optimization of the treatment effect.

[0023] 1. This adjustable post-burn hypertrophic scar treatment device controls the operation of the first motor through a controller to drive the screw to rotate, thereby driving the arch bridge to move on the bed, so that the arch bridge moves to a position above the scar, and starts the second motor to drive the slider to move along the arch bridge, so that the airbag is aligned with the scar position, and starts the first electric push rod to make the airbag contact with the scar, and starts the air pump to inflate the trachea, thereby expanding the airbag and squeezing the scar, thereby achieving a compression effect on the scar, promoting recovery, and avoiding scar thickening.

The end of the knob 65 is in conflict with the fixing ring 62, thereby facilitating the installation of the mesh 64. The mesh 64 can prevent the airbag 36 from directly rubbing against the scar and avoid damage to the skin. At the same time, after the treatment is completed, the mesh 64 can be cut off and then bandaged on it to avoid waste of residual liquid medicine.

[0050] In the present invention, a dosing mechanism 4 is connected to the bed 1, and the dosing mechanism 4 includes a medicine bottle 41.

[0052] Example 3:

[0053] On the basis of Example 2, an adjustable post-burn hypertrophic scar treatment device is provided, wherein a knocking mechanism 8 is connected to the airbag 36, and the knocking mechanism 8 includes a fixed block 85. The fixed block 85 is installed at the inner bottom end of the airbag 36, and a plurality of knocking columns 87 are slidably connected to the bottom end of the fixed block 85. The bottom ends of the knocking columns 87 pass through the airbag 36, and the bottom ends of the knocking columns 87 are in contact with the surface of the rubber sleeve 35, thereby facilitating the knocking of the scar.

[0054] In the present invention, a first spring 88 is installed between the knocking column 87 and the fixed block 85, and a pushing block 86 is slidably connected inside the fixed block 85. The bottom end of the pushing block 86 is in conflict with the knocking column 87, and the end where the pushing block 86 and the knocking column 87 are in conflict is wavy. A fourth motor 82 is installed on the fixed block 85, and an eccentric block 84 is installed on the output shaft of the fourth motor 82. A slot 83 is provided on the pushing block 86, and the eccentric block 84 extends into the interior of the slot 83. The outer edge of the eccentric block 84 is in conflict with the pushing block 86. A telescopic rod 81 is installed between the fixed block 85 and the fixed shell 34, so as to facilitate uninterrupted knocking of the scar and promote softening.

[0055] Working principle: let the scar patient lie on the bed body 1, and control the first motor 22 to work through the controller 52, drive the screw rod 23 to rotate, thereby driving the arch bridge 31 to move on the bed body 1, so that the arch bridge 31 moves to a position above the scar, start the second motor 333, drive the first gear 336 to rotate, and under the action of the gear segment 334, drive the slider 332 to move along the arch bridge 31, so that the airbag 36 is aligned with the scar position, start the first electric push rod 337, thereby pushing the fixed cylinder 32 to move downward along the sliding cylinder 331, so that the airbag 36 contacts the scar, start the air pump 53, and the air pump 53 inflates the trachea 51, so that the airbag 36 expands, thereby squeezing the scar, thereby achieving a compression effect on the scar, promoting recovery, and preventing scar thickening. According to different scar positions, the arch bridge 31 is arc-shaped, which is convenient for adjusting the position of the airbag 36. Scars on the side of the trunk can also be accurately aligned. The patient does not need to adjust his posture, which is more convenient.

[0056] Before applying pressure to the scar, the rubber sleeve 35 is put on the bottom end of the fixed shell 34 to wrap the airbag 36, so that the extrusion strip 44 is inserted into the slot 45, and the delivery pipe 43 is connected with the spray hole 46 on the extrusion strip 44. The second electric push rod 91 is started, and the pull rod 96 is pulled through the control block 95 to drive the clamping block 93 to rotate, so that the clamping block 93 extends into the inside of the clamping groove 94, thereby limiting the extrusion strip 44, and the fixing ring 62 is inserted into the mounting ring 63. The knob 65 is tightened so that one end of the knob 65 contacts the fixing ring 62, thereby limiting the fixing ring 62, and the bottom end of the mesh 64 contacts the bottom end of the rubber sleeve 35. During the process of applying pressure to the scar, the airbag 36 squeezes the rubber sleeve 35 and the mesh 64 so that they are in close contact with the surface of the scar, and the third motor 71 is started to drive the second gear 73 to rotate. The inner gear 72 drives the fixed shell 34 to rotate, thereby driving the airbag 36 and the rubber sleeve 35 to rotate. The mesh 64 is connected to the fixed cylinder 32, so as to remain stationary. The liquid pump 42 is started to extract the liquid medicine in the medicine bottle 41, input it into the inside of the delivery tube 43, and spray it out from the spray hole 46 on the bottom side of the extrusion strip 44. As the extrusion strip 44 rotates, the liquid medicine is applied to the mesh 64, infiltrated through the mesh 64 and reaches the scar epidermis. Through pressure and the rotational friction of the rubber sleeve 35, the scar is promoted to absorb the liquid medicine, thereby achieving a therapeutic effect. After the treatment is completed, the mesh 64 and the rubber sleeve 35 are removed. The mesh 64 can be cut off from the fixed ring 62 so that it can be applied to the scar, which is not convenient for the absorption of the remaining liquid medicine. The rubber sleeve 35 plays a partition role. When the next patient uses it, a new one can be replaced to avoid cross infection.

[0057] When the airbag 36 and the rubber sleeve 35 rotate and rub, the fourth motor 82 is started, the telescopic rod 81 supports the fixed block 85, and the fourth motor 82 drives the eccentric block 84 to rotate, thereby pushing the pushing block 86 to move back and forth through the empty slot 83. The bottom end of the pushing block 86 is wavy, thereby pushing the knocking column 87 to extend, and the first spring 88 is compressed. When the thrust of the knocking column 87 is released, the first spring 88 pushes the knocking column 87 to reset, and the knocking column 87 continuously hits the rubber sleeve 35, thereby transmitting the knocking force to the mesh 64 and the scar surface, thereby promoting scar softening.

Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
