Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular to a medical adjustable elastic cap. Background Technology

[0002] Elastic caps are generally used for head bandaging. They are elastic and can firmly fix the gauze used for bandaging. However, because they are universal products, they cannot be adjusted according to the size of the user's head. This can result in excessive elasticity, which can chafe the skin of the head or face, causing pressure injuries and affecting the user experience.

[0003] A search revealed a Chinese patent document (authorization announcement number CN208525231U), indicating that this utility model relates to a medical adjustable elastic cap, comprising a head cover and a neck strap. The head cover includes an elastic net and an elastic band. The elastic band is connected to the lower edge of the elastic net in a circumferential, non-closed manner. The elastic band is provided with an adjustment cord and a first adjustment buckle. One end of each of the two adjustment cords is connected to the elastic band and fixed by the first adjustment buckle. A zipper is provided on the elastic net. The neck strap is provided with a first pad, a second pad, and a second adjustment buckle. The two first pads are movably connected to the neck strap on both sides of the second pad. The zipper allows for replacement of the gauze dressing inside the cap without removing the net. Although it can tighten the head, it is a general-purpose product and cannot be adjusted according to the user's head size. This could result in excessive elasticity, causing pressure sores on the head or face, affecting the user experience. Utility Model Content

[0004] The purpose of this invention is to provide a medical adjustable elastic cap to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a medical adjustable elastic cap, comprising a medical elastic cap body, with multiple equidistant wrapping straps arranged around the outer periphery of the elastic cap body, both sides of which are sewn to the elastic cap body, a storage space between the wrapping straps and the elastic cap body, an elastic band for tightening the elastic cap body within the storage space, and an adjustment rope connected to both sides of the elastic band, a cylindrical mounting box on the side of the elastic cap body, an active shaft inside the mounting box, an adjustment knob fixedly connected to the top of the active shaft through the mounting box, and an anti-slip texture for increasing friction on the outer periphery of the adjustment knob, two winding wheels fixedly connected to the outer periphery of the active shaft located inside the mounting box, and the outer periphery of the winding wheels being fixedly connected to the adjustment rope.

[0006] As a preferred embodiment, a limiting ring plate is fixedly connected to the inner wall of the mounting box, and the inner wall of the limiting ring plate is provided with teeth.

[0008] As a preferred embodiment, a spring is sleeved on the outer periphery of the drive shaft, with the spring positioned between the mounting box and the winding wheel.

[0009] As a preferred embodiment, the outer periphery of the elastic cap body is connected with a tightening strap, and the mounting box is detachably connected to the elastic cap body.

[0010] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0011] This medical adjustable elastic cap benefits from the design of the adjustment knob and the winding wheel. By turning the adjustment knob, the two winding wheels on the outer periphery of the drive shaft will rotate. The rotation of the winding wheels can wind the two adjustment ropes into the mounting box, thereby pulling the elastic band to tighten the head. The elastic band can be operated at different positions to tighten to different degrees. It can be adjusted according to the patient's head shape and skull size, which can effectively fix the head and prevent it from falling off and causing the wound to be exposed and infected. It can also be used to treat subcutaneous effusion after craniocerebral surgery and prevent brain herniation in patients after osteotomy.

[0012] This medical adjustable spring cap allows the insert plate of the drive shaft to be inserted into the nearest slot after rotation, ensuring the stability of the drive shaft and the associated winding wheel. The spring's restoring force also ensures the stability of the drive shaft. When operation is required, simply pull up the adjustment knob to disengage the insert plate from the slot of the limiting ring plate, and then rotate to perform the winding operation.

[0013] This medical adjustable elastic cap allows for the winding of the adjustment cord and the pulling of the elastic band to meet different tightening needs. Attached Figure Description

[0025] Examples, such as Figures 1 to 5 As shown, a medical adjustable elastic cap,

[0026] The device includes a medical elastic cap body 1. Multiple equidistant wrapping straps 2 are arranged around the outer periphery of the elastic cap body 1. Both sides of the wrapping straps 2 are sewn to the elastic cap body 1. A storage space is provided between the wrapping straps 2 and the elastic cap body 1. An elastic band 3 for tightening the elastic cap body 1 is located within the storage space. Adjustable ropes 4 are connected to both sides of the elastic band 3. A cylindrical mounting box 6 is located on the side of the elastic cap body 1. An active shaft 7 is located inside the mounting box 6. An adjustment knob 8 is fixedly connected to the top of the active shaft 7 through the mounting box 6. Rotating the adjustment knob 8 allows adjustment of the extension of the two adjustment ropes 4, making it easy for the patient to adjust the tightness of the elastic cap body 1 and preventing the adjustment ropes 4 from affecting comfort. The outer periphery of the adjustment knob 8 has anti-slip textures to increase friction. Two winding wheels 9 are fixedly connected to the outer periphery of the active shaft 7 inside the mounting box 6, and the outer periphery of the winding wheels 9 is connected and fixed to the adjustment ropes 4.

[0027] To ensure stability, a limiting ring plate 12 is fixedly connected to the inner wall of the mounting box 6. The inner wall of the limiting ring plate 12 has teeth. Multiple insert plates 13 that are adapted to the teeth are fixedly connected to the outer periphery of the drive shaft 7. A spring 14 is sleeved on the outer periphery of the drive shaft 7. The spring 14 is located between the mounting box 6 and the winding wheel 9 and is close to the adjustment knob 8. After rotation, the insert plate 13 of the drive shaft 7 is inserted into the gap of the nearest slot, which can ensure the stability of the drive shaft 7 and the auxiliary winding wheel 9. The restoring force of the spring 14 can ensure the stability of the drive shaft 7. When operation is required, pull up the adjustment knob 8 to make the insert plate 13 disengage from the slot of the limiting ring plate 12, and then rotate to perform the winding operation.

[0028] The outer periphery of the elastic cap body 1 is connected to a tightening strap 11, and the mounting box 6 is detachably connected to the elastic cap body 1.

[0029] The mounting box 6 is a detachable structure, which can be used to adapt to the need to replace different elastic cap bodies 1 and adjustment ropes 4.

[0030] It should be noted that the elastic cap body 1 has good elasticity and breathability, and its size can meet the needs of most heads. It is tightened by the elastic band 3. When in use, the elastic cap body 1 can tighten around the back of the head without covering the ears.

[0031] Working principle

[0032] When using this medical adjustable elastic cap, the cap body 1 is put on and secured with the tightening strap 11. Pulling up the adjustment knob 8 disengages the insert plate 13 from the slot of the limiting ring plate 12. Rotating the adjustment knob 8 drives the two winding wheels 9 on the outer periphery of the drive shaft 7 to rotate. The rotation of the winding wheels 9 can wind the two adjustment ropes 4 into the mounting box 6, tightening the elastic band 3 and thus increasing the restraint on the head. After reaching the specified restraint, pressing down the adjustment knob 8 inserts the insert plate 13 of the drive shaft 7 into the gap of the nearest slot, ensuring the stability of the drive shaft 7 and the auxiliary winding wheels 9. The restoring force of the spring 14 ensures the stability of the drive shaft 7.
