[0026] In the prior art, due to the long treatment course of keloids, patients need to go to the hospital for injections multiple times, consuming a large amount of time of the patients.
[0027] To solve this technical problem, the present utility model provides an indwelling injection treatment device 1000, which does not require patients to travel back and forth to the hospital, and solves the problem of time consumption during the treatment course.
[0028] Please refer to Figure 1 and Figure 2 , the indwelling injection treatment device 1000 is used for the treatment of keloids, and the indwelling injection treatment device 1000 includes:
[0029] A housing 1, the housing 1 is provided with a cavity with an opening at the bottom;
[0030] The injection device 2 is located within a cavity. The injection device 2 includes a liquid storage barrel 21 and at least one indwelling needle 22. The liquid storage barrel 21 is used to store the medicinal liquid. The indwelling needle 22 is in communication with the liquid storage barrel 21. The indwelling needle 22 is arranged facing the opening of the outer shell 1. The indwelling needle 22 is used to be indwelled within the scar tissue. The injection device 2 is used to inject the medicinal liquid into the scar tissue.
[0031] Multiple fixing straps 3. The fixing straps 3 are detachably connected to the outer shell 1. The fixing straps 3 are used to fix the outer shell 1 onto the scar tissue.
[0032] In this solution, the indwelling injection treatment device 1000 includes an outer shell 1, an injection device 2, and multiple fixing straps 3. By arranging the injection device 2 within the cavity of the outer shell 1 and then fixing the outer shell 1 onto the scar tissue through the multiple fixing straps 3, the indwelling needle 22 in the injection device 2 can be indwelled within the scar tissue for a long time, eliminating the need for multiple needle insertions during each injection treatment, reducing the pain of the patient. At the same time, due to the provision of the liquid storage barrel 21, the medicinal liquid can be stored in the liquid storage barrel 21, enabling the patient to perform the injection operation at home without having to make multiple trips to the hospital. Among them, the injection device 2 can be a traditional manually squeezed type or an electronic driving member can be arranged within the cavity to drive the extrusion injection. The method of using an electronic driving member to drive the extrusion injection can ensure a relatively stable injection process.
[0033] In an embodiment of the present utility model, the indwelling needle 22 is a micro-needle. The diameter of the micro-needle is from 0.2 mm to 0.5 mm. The number of micro-needles is multiple. The multiple micro-needles are inserted into the scar tissue to achieve injection, and the micro-needles cause less pain to the patient.
[0034] Please refer to Figure 1 and Figure 2 , in an embodiment of the present utility model, a holding ring 11 is fixed to the outer peripheral edge of the bottom end of the outer shell 1. The holding ring 11 abuts against the skin around the scar tissue. The provision of the holding ring 11 is used to abut against the skin, increasing the contact area between the entire device and the skin and enhancing the stability of the product when worn on the human body for a long time.
[0035] Among them, a flexible pad is provided at the bottom of the holding ring 11. With such an arrangement, the comfort of the device when worn on the human body for a long time is improved. The flexible pad can be a sponge or a textile material, which plays a role in absorbing sweat to a certain extent.
[0036] Please refer to Figure 1 and Figure 2, in an embodiment of the present utility model, a plurality of fixing rods 12 are arranged at intervals along the circumferential direction of the abutting ring 11. There is a gap between the fixing rods 12 and the abutting ring 11. Two magic tapes are arranged at one end of the fixing belt 3 at intervals. One end of the fixing belt 3 passes through the gap between the fixing rods 12 and the abutting ring 11, and the two magic tapes at one end of the fixing belt 3 are adhered tightly to assemble one end of the fixing belt 3 to the fixing rods 12. After winding one end of the fixing belt 3 around the fixing rods 12, it is fixed by the two magic tapes. The fixing stability is relatively high, and the fixing belt 3 can be removed to replace the type of the fixing belt 3.
[0037] Wherein, the other end of the fixing belt 3 is provided with an adhesive part, and the adhesive part adheres to the skin surface to fix the outer shell 1 on the scar tissue. It is applicable to the scar tissue on the front chest or back. Since the skin around the scar tissue is a whole piece, it is directly adhered to the skin surface through the adhesive part, and its applicability is relatively strong.
[0038] The components of the adhesive in the adhesive part include polyacrylate and polyester resin. On the premise of ensuring the bonding strength of the adhesive part, the air permeability of the adhesive part can be improved to avoid discomfort of the human body caused by long-term wearing. Moreover, the polyester resin can also play a certain waterproof effect.
[0039] At the same time, a plurality of ventilation holes are opened on the surface of the fixing belt 3. The ventilation effect is further improved. The comfort of wearing is improved.
[0040] In an embodiment of the present utility model, both the fixing belt 3 and the abutting ring 11 are provided with buckle structures, and the fixing belt 3 and the abutting ring 11 are connected by buckles.
[0041] Wherein, the number of the fixing belts 3 is two, and the two fixing belts 3 are arranged oppositely. One end of one of the fixing belts 3 is provided with an adjusting buckle (not shown), and the other fixing belt 3 passes through the adjusting buckle. The two fixing belts 3 tie the outer shell 1 to the human limb to fix the outer shell 1 on the scar tissue. The adjusting buckle is used to adjust the tying diameter formed by the two fixing belts 3. With such a setting, it is applicable to the situation where the scar tissue grows on the arm or leg. The outer shell 1 can be directly tied to the limb through the adjusting buckle on the fixing belt 3, and the adjusting buckle can also adjust the tightness of the tying, improving the practicality of the product.
[0042] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural transformations made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present utility model.
