Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water injection bag, in particular to a water injection storage box for dilator. BACKGROUND

[0002] Congenital microtia is a group of maxillofacial deformities caused by abnormal development of the first and second branchial arches and their adjacent tissues during embryonic period. It is often manifested as auricle deformity, external auditory canal atresia and middle ear deformity. The main treatment method at present is auricle reconstruction. Successful auricle reconstruction depends on two factors: auricle support and skin covering the support. The damaged auricle is treated by using ear dilator. The "extra" skin obtained after expansion is used to repair the defects of the adjacent skin. The color and texture of the skin are uniform, and are basically the same as the skin to be repaired, so that the ideal plastic effect is achieved.

[0003] The dilator is a special advanced treatment method in plastic surgery. The principle is to implant a skin soft tissue expander under the normal skin soft tissue near the lesion, and to increase the capacity of the expander by intermittently injecting liquid into the expansion capsule to generate pressure on the surface skin soft tissue. Since the expansion needs to be carried out slowly, skin necrosis is avoided.

[0004] The water injection treatment cycle of the dilator currently needs 5 months. Since the water injection cycle is too long, the patient needs to regularly go to the hospital to add water. The physiological saline is added into the dilator through a syringe. It is troublesome for the patient to go to the hospital many times. A water injection bag that can be used at home to add water to the dilator is needed. However, the existing water injection bag does not have a positioning function. When the patient's family members use the existing water injection bag to inject water, it is not easy to find the injection port on the top of the patient's head, and it is easy to deviate. Moreover, the amount of physiological saline injected each time is usually a few milliliters to a few tens of milliliters.

[0053] When the bottle mouth of the injection bottle 50 needs to be inserted into the inside of the installation end of the clamping barrel 41, the sliding rod 49 is pulled outwards, the rotating shaft 48 slides in the second sliding groove 414, and the length of the second spring 47 is stretched by the sliding rod 49; when the end of the sliding rod 49 away from the placement plate 46 appears in the avoiding groove 413, the sliding rod 49 is turned to one side of the clamping barrel 41, so that the sliding rod 49 and the clamping barrel 41 form a 90-degree angle; then the bottle mouth of the injection bottle 50 is inserted into the inside of the installation end of the clamping barrel 41, the sliding rod 49 is turned to reset, the sliding rod 49 is reinserted into the first sliding groove 412, and the placement plate 46 extrudes the injection bottle 50 to have a certain extrusion force in the direction of the flapper 42 due to the elastic recovery of the second spring 47, so that the rubber plug 51 always abuts against the flapper 42, the injection bottle 50 is fixed, and falling is prevented, and it is convenient for the syringe 20 to extract physiological saline.

[0054] As shown in Figure 8 In this embodiment, the positioning assembly 30 includes a positioning cylinder 31, a positioning ring 32, a positioning cover 33, and a blocking ring 34. The positioning ring 32 is fixedly sleeved at the top of the inside of the positioning cylinder 31, and the top of the positioning ring 32 protrudes outwardly to the top of the positioning cylinder 31. The positioning cover 33 is funnel-shaped with a large top and a small bottom. The top of the positioning cover 33 is fixedly connected with the bottom surface of the positioning cylinder 31. The blocking ring 34 is fixedly sleeved at the inside of the positioning ring 32. The front end of the injection sleeve 21 can be inserted into the positioning ring 32, and the front end surface of the injection sleeve 21 abuts on the positioning ring 32, so that the injection needle 22 is inserted into the injection port at the front end of the patient.

[0055] When the physiological saline is drawn by the injector 20, the positioning cylinder 31 is taken out. The bottom of the positioning cover 33 is aligned with the injection port on the head, so that the injection port on the head is located inside the bottom of the positioning cover 33. At this time, the bottom end surface of the positioning ring 32 abuts on the injection port. Then, the injection sleeve 21 is inserted into the positioning ring 32, so that the front end surface of the injection sleeve 21 abuts on the top surface of the blocking ring 34. At this time, the injection needle 22 is just inserted into the injection port on the head. This is beneficial for the family member to inject the physiological saline. Moreover, the setting of the blocking ring 34 avoids the injection needle 22 from being inserted too deeply into the injection port on the head.

The length of the bottle groove 131 is greater than the length of the injection bottle 50, so that a gap is left in the bottle groove 131, which facilitates the fingers to stretch into the bottle groove 131 to take out the injection bottle 50. The top of the two inner side walls of the bottle groove 131 is fixedly provided with a shade 132. The shade 132 is elastic. When the injection bottle 50 is placed into the bottle groove 131, the shade 132 covers the injection bottle 50, thereby playing a fixing role and avoiding the injection bottle 50 from shaking and separating from the bottle groove 131. When the injection bottle 50 needs to be taken out, the shade 132 can be squeezed away by pinching the injection bottle 50 upwardly due to the elasticity of the shade 132.
