Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary appliances, in particular to a pressure bandaging device after brain surgery. Background Art

[0002] After cranial surgery, the patient's wound needs to be bandaged. The common method is to use a gauze bandage. However, since the pressure of the bandage cannot be accurately controlled, the bandage is often not tight due to patient activity or lack of doctor experience, which can easily cause it to fall off. Moreover, over time, it is almost inevitable that the pressure will relax and release, causing subcutaneous effusion or bleeding in the patient. If the amount of subcutaneous effusion is relatively small, local pressure bandage can be applied, and the head CT scan should be reviewed regularly to observe changes in the amount of effusion. If the effusion gradually decreases, proving that the treatment is effective, the pressure bandage can be continued until the subcutaneous effusion is absorbed. For local pressure application, it needs to be implemented in a targeted manner at the location where the symptoms appear. There should be no omissions, and the pressure application area should not be too large to burden the healthy area.

[0003] In addition, if the effect of pressurization is not obvious, drainage is required. During the drainage process, a cap is usually worn on the patient's head to better compress the auxiliary materials adhered to the patient's scalp wound. The drainage tube used for drainage of the cranial surgery wound is led out through the lower periphery of the corresponding cap. However, this will also compress the drainage tube used for drainage of the cranial surgery wound, making the drainage tube easily bent under pressure and its internal bending position blocked, which can easily cause drainage interruption, making it unreliable to use. At the same time, the drainage tube used for drainage of the cranial surgery wound is not very fixed and is easily pulled and caused to fall off, making it less safe to use.

[0004] After searching, the Chinese patent with the announcement number CN207101390U proposed a shell pressurized cap, including a headgear body, a temporal airbag is arranged at the temporal part of the headgear body, an occipital airbag is arranged at the back occipital part of the headgear body, a top airbag is arranged at the top of the headgear body, and a drainage hole is arranged on the headgear body. The utility model has a simple structure, is easy to wear, is convenient and quick to use by surgeons, and can perform zoned pressurization on the brain, and the pressurization effect is obvious when used by patients.

[0005] However, fixed partitioned airbags have certain limitations. If the wound is located between two airbags, the airbag coverage will be incomplete and the pressurization effect will be poor. Although the drainage hole can extend the drainage tube, part of it is still at the bottom of the airbag. The drainage tube is compressed, which will cause blockage of the drainage tube and affect the drainage effect. Summary of the invention

[0006] In view of the above-mentioned problems, the utility model aims to provide a pressure bandage device after brain surgery, so that the position of the airbag can be moved according to the position of the wound, and the pressure is limited to the wound range; the drainage tube passes through the bottom of the airbag and the headband and is not compressed.

[0007] The main ideas of the technical solution adopted by the utility model are: by designing multiple groups of connection structures inside the headband, the position of the airbag can be adjusted and the airbag pressurization range is accurate; by setting an arc-shaped groove at the bottom of the airbag, the airbag is sunken to form a concave structure after being filled, which is convenient for the drainage tube to pass through; by designing a detachable clamping structure, the clamping structure can be installed according to the position of the airbag, so as to support space for the drainage tube and avoid it from being compressed.

[0016] Through the above technical solution, further: an arc-shaped groove is provided on one side of the airbag, so that the airbag is sunken to form a concave structure after being filled.

[0017] The beneficial effects of the utility model are:

[0018] By designing multiple sets of connection structures inside the headband, the position of the airbag can be adjusted and the airbag pressurization range is accurate;

[0019] By providing an arc-shaped groove at the bottom of the airbag, the airbag is sunken to form a concave structure after being filled, which is convenient for the drainage tube to pass through;

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0031] The inventors have found that patients may have subcutaneous effusion or bleeding after craniocerebral surgery. If the amount of subcutaneous effusion is relatively small, local pressure bandage can be applied. The existing pressure headgear uses fixed partitioned airbags, which has certain limitations. If the wound is located between two airbags, it will lead to incomplete airbag coverage and poor pressure effect. In addition, if the pressure effect is not obvious, drainage is required. During the drainage process, the drainage tube is partially at the bottom of the headgear. The drainage tube is compressed, which will cause the drainage tube to be blocked, affecting the drainage effect and making it unreliable to use. At the same time, it is easy to be pulled and cause the tube to fall off, making it less safe to use.

[0032] Based on the above findings, the present application proposes a post-brain surgery pressurization bandage device, which makes the position of the airbag adjustable and the airbag pressurization range precise by designing multiple sets of connection structures inside the headband; by providing an arc-shaped groove at the bottom of the airbag, the airbag is sunken to form a concave structure after being filled, which is convenient for the drainage tube to pass through; by designing a detachable clamping structure, the clamping structure can be installed according to the position of the airbag, thereby providing space for the drainage tube to prevent it from being compressed. Example

[0033] See also Figure 1-Figure 3 The present application discloses a post-brain surgery pressurized bandage device, comprising a headband body 1, wherein the headband body 1 comprises an inner headband 2 and an outer headband 3 connected to each other, wherein the inner layer is made of an elastic material, such as nylon, to facilitate pressurizing the head after the airbag 4 is inflated, and the outer layer is made of a material with less elasticity. Since the materials of the inner and outer layers are different, after the airbag 4 is inflated, the inner layer is more easily squeezed toward the wound on the head, while the shape of the outer layer is not easily changed, which can concentrate the pressure and enhance the pressurization effect.

[0034] The headband body 1 is provided with an opening, which enables the airbag 4 to enter the headband body 1. The airbag 4 can slide everywhere inside the headband body 1, and the position where the airbag 4 acts is determined according to the wound position. In order to fix the airbag 4 at the wound position, a connecting structure is provided inside the headband body 1, and the connecting structure is used to connect the inner headband 2 and the outer headband 3. Multiple groups of connecting structures surrounding the wound area are connected to each other to form a closed area, which limits the activity space of the airbag 4.

[0035] There are multiple groups of connection structures, which are evenly distributed inside the headband. The connection structures are connected to each other, so that the inner headband 2 and the outer headband 3 are connected to each other and fit each other. The connection structure includes a Velcro fleece surface 6 and a Velcro hook surface 7 that cooperate with each other. The Velcro fleece surface 6 is fixedly arranged on the inner side of the outer headband 3, and the Velcro hook surface 7 is fixedly arranged on the outer side of the inner headband 2. When in use, the connection structures around the wound area are connected to each other, that is, the corresponding Velcro fleece surface 6 and Velcro hook surface 7 are connected together respectively, so that the inner headband 2 and the outer headband 3 at the corresponding positions are connected to each other and fit each other, while the connection structures in the wound area remain separated from each other, and at the same time provide space for the subsequent placement of the airbag 4. Example

[0036] refer to Figure 4-Figure 6 In order to prevent the drainage tube 9 from being folded or falling off, an arc-shaped groove 8 is provided on one side of the airbag 4, so that the airbag 4 is sunken to form a concave structure after being filled, and a channel is reserved for the drainage tube 9 led out of the wound area. At the same time, the pressurization effect at the sunken part of the airbag 4 will definitely be affected. Therefore, each time the airbag 4 is placed, it is rotated 180° compared with the last position, so that the drainage tube 9 is led out from the top and bottom of the headband respectively, and the head positions corresponding to each sunken position are staggered, reducing the influence of the groove 8 of the airbag 4 on the pressurization effect. Example

[0037] refer to Figure 7-Figure 8 After the drainage tube 9 is led out from the wound area, a clamping structure 5 for fixing is required. The clamping structure 5 is arranged on both sides of the headband body 1. A plurality of small holes are arranged on both sides of the headband body 1. The clamping structure 5 passes through the small holes to fix the drainage tube 9 so that it extends along the headband body 1, which is convenient for observing the internal situation of the drainage tube 9. The clamping structure 5 includes a fixed ring 1 and a fixed ring 2 that are hinged to each other. The fixed ring 1 and the fixed ring 2 include a semicircular ring for fixing the drainage tube 9. The size of the semicircular ring is adapted to the drainage tube 9. The bottom of the fixed ring 1 is fixedly connected with two symmetrically arranged L-shaped parts. The fixed shaft is fixedly connected between the two symmetrically arranged L-shaped parts. The bottom of the fixed ring 1 is fixedly connected with an L-shaped part, and is sleeved on the fixed shaft, so that the fixed ring 1 and the fixed ring 2 can be hinged through the fixed shaft and rotate around the fixed shaft. The surfaces where the fixed ring 1 and the fixed ring 2 contact are embedded with magnetic parts that attract each other, so that the fixed ring 1 and the fixed ring 2 are closed to each other to form a circular channel, which is convenient for fixing the drainage tube 9. Example

[0038] In order to facilitate accurate adjustment of the pressure inside the airbag 4 and thereby control the degree of pressurization on the wound, the airbag 4 is connected to a pressure gauge, through which the pressure can be observed, and the gas pressure can be increased or decreased throughout the course of the disease according to the dressing requirements at different stages after the operation, so as to achieve appropriate pressurization, promote healing effects, and reduce subcutaneous effusion and delayed wound healing caused by inadequate pressurization during cranial surgery.

[0039] The use process of this utility model is:

[0040] (1) First, put on the headband body 1, with the front headband being narrower and the back headband being wider;

[0041] (2) Determine the position where pressure needs to be applied according to the position of the wound, insert the airbag 4 through the opening on one side of the headband body 1, and move the airbag 4 to the designated position, connect the Velcro fleece surface 6 around it with the Velcro hook surface 7, that is, the inner headband 2 and the outer headband 3 are fitted together, restrict the movement of the airbag 4, and fix it at the designated position;

[0042] (3) Inflate the airbag 4 using an external air pump and observe the pressure using a pressure gauge;

[0043] (4) When drainage is required, one end of the drainage tube 9 is fixed in the wound, and the drainage tube 9 extends out of the headband body 1 along the arc-shaped groove 8 of the airbag 4, and the drainage tube 9 is fixed by the clamping structure 5 on both sides of the headband body 1, so that the drainage tube 9 is fixed on both sides of the headband body 1, which is convenient for observing the situation inside the drainage tube 9.
