Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a sternum external fixation device after thoracotomy. Background Art

[0002] The heart is one of the most important organs in the human body. It promotes blood flow, provides sufficient blood flow to organs and tissues to supply oxygen and various nutrients, and takes away the end products of metabolism, so that cells maintain normal metabolism and function. After open-chest surgery, a chest strap is routinely used to fix the heart to relieve pain and promote sternum healing. The tightness of the chest strap should be one finger. The tightness is judged clinically based on experience, and the pressure of the chest strap varies depending on the material.

[0003] In the prior art, for example, publication number CN219847095U discloses a chest strap for fixing after thoracotomy, which includes a fixing strap fixed at both ends in the length direction by Velcro, an air bag is arranged on the inner side of the fixing strap, an air inlet pipe is connected to the outer side of the fixing strap, one end of the air inlet pipe is connected to the air bag, and the other end of the air inlet pipe is connected to a negative pressure ball, an exhaust valve is connected to the outer side of the fixing strap, and the exhaust valve is connected to the air bag, and pads are arranged at both ends of the upper side of the fixing strap.

[0004] In the above scheme, after the fixing belt is tied to the patient's body with Velcro, the airbag is inflated to expand it, so as to exert pressure on the patient's body to adjust the tightness. There is no need to tear the Velcro and stick it again to try to adjust the tightness many times. It is easy to use, and the airbag expands slowly, and the pressure on the patient's body gradually increases. When the tightness is appropriate, the inflation can be stopped, so as to achieve the purpose of accurately adjusting the tightness. However, in the above scheme, the fixing belt is an inverted trapezoidal structure with a larger upper part and a smaller lower part. If the patient is fat, especially when the abdomen is larger, the structure of the fixing belt makes the patient's abdomen very uncomfortable. In addition, in order to make the fixing belt fit the patient's body, the fixing belt is attached at the Velcro connection point where the fixing belt is skewed, and the end of the fixing belt is easily higher than the fixing belt, which is likely to affect the patient's activity. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a sternum external fixation device after thoracotomy, so that the fixation device is suitable for patients with different body shapes.

[0006] The utility model is achieved in this way:

[0010] In the above technical solution, the first airbag block is in the shape of a right-angled triangle.

[0011] In the above technical solution, the second airbag mechanism includes: a second airbag block, a second inflation hole and a second sealing plug; the second airbag block is arranged in the containing layer, and the second airbag block is fixedly connected to the cotton cloth; the second inflation hole is opened on the fixing belt, and the position of the second inflation hole corresponds to the position of the second airbag block; the second sealing plug is arranged in cooperation with the second inflation hole.

[0012] In the above technical solution, the side hole mechanism includes: a side hole and a snap button; the side hole is opened on one side of the fixing belt; and at least one snap button is arranged on the opposite side of the side hole.

[0013] The above technical solution also includes: ventilation holes, a plurality of ventilation holes are opened between the plurality of first airbag blocks.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. By fixing cotton cloth on the inner side of the fixing belt, the fixing device is set to a double-layer structure, a containing layer is formed between the fixing belt and the cotton cloth, and the first airbag mechanism is symmetrically arranged in the containing layer, so that the fixing device is suitable for patients of different body shapes. If the patient is thin (less abdominal meat), the first airbag mechanism below can be inflated to form an inverted trapezoidal structure on the inner side of the fixing belt to reduce the situation that the upper part is too tight while the lower part is still relatively loose; if the patient is fatter (more abdominal meat), the first airbag mechanism above can be inflated to form a trapezoidal structure on the inner side of the fixing belt to reduce the situation that the lower part is too tight while the upper part is still relatively loose; if the patient has a well-proportioned body shape (the dimensions of the ribs and the abdomen are almost the same), there is no need to inflate the first airbag mechanism, and the two ends of the fixing belt can be directly fixed with Velcro.

[0016] 2. By setting up a second airbag mechanism, pressure is applied to the patient's body to achieve the purpose of adjusting the tightness. There is no need to tear off the Velcro and stick it again to try to adjust the tightness many times. It is easy to use, and the airbag expands slowly, and the pressure on the patient's body gradually increases. When the tightness is appropriate, stop inflating, thereby achieving the purpose of accurately adjusting the tightness.

[0017] 3. By setting up the side hole mechanism, since a chest drainage tube is generally routinely left in place after cardiac thoracotomy, when the fixation belt is worn, the chest tube is directly pressed under the chest belt, which has the risk of pressure injury and is not conducive to direct observation of the drainage tube outlet of the wound. Therefore, by setting up the side hole mechanism, the chest drainage tube can be passed through the side hole mechanism to avoid skin pressure and facilitate observation.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] A sternum external fixation device after thoracotomy, such as Figure 1-4 As shown, it includes: a fixing belt 100, a shoulder strap 110, a cotton cloth 120, a containing layer 130, a first airbag mechanism 200, a second airbag mechanism 300 and a side hole mechanism 400; the two ends of the fixing belt 100 can be attached together by Velcro; the ends of the two shoulder straps 110 are respectively connected to the fixing belt 100; the cotton cloth 120 is fixedly connected to the fixing belt 100; the containing layer 130 is a hollow cavity formed between the fixing belt 100 and the cotton cloth 120; the two first airbag mechanisms 200 are symmetrically arranged in the containing layer 130; the second airbag mechanism 300 is arranged on the inner side of the cotton cloth 120; and the two side hole mechanisms 400 are respectively arranged on both sides of the fixing belt 100.

[0026] By fixing the cotton cloth 120 on the inner side of the fixing belt 100, the fixing device is set to a double-layer structure, a containing layer 130 is formed between the fixing belt 100 and the cotton cloth 120, and the first airbag mechanism 200 is symmetrically arranged in the containing layer 130, so that the fixing device is suitable for patients of different body shapes. If the patient is thin (less abdominal meat), the first airbag mechanism 200 below can be inflated to form an inverted trapezoidal structure on the inner side of the fixing belt 100 to reduce the situation that the upper part is too tight while the lower part is still relatively loose; if the patient is fat (more abdominal meat), the first airbag mechanism 200 above can be inflated to form a trapezoidal structure on the inner side of the fixing belt 100 to reduce the situation that the lower part is too tight while the upper part is still relatively loose; if the patient has a well-proportioned body shape (the dimensions of the ribs and the abdomen are almost the same), there is no need to inflate the first airbag mechanism 200, and the two ends of the fixing belt 100 can be directly fixed with Velcro; By setting the second airbag mechanism 300, pressure is applied to the patient's body to achieve the purpose of adjusting the tightness. There is no need to tear off the Velcro and then stick it again to try to adjust the tightness many times. It is easy to use, and the airbag expands slowly, and the pressure on the patient's body gradually increases. When the tightness is appropriate, the inflation can be stopped, thereby achieving the purpose of accurately adjusting the tightness; by setting the side hole mechanism 400, since a chest drainage tube is generally routinely left in after cardiac thoracotomy, when the fixing belt 100 is worn, the chest tube is directly pressed under the chest belt, which poses a risk of pressure injury and is not conducive to directly observing the outlet of the wound drainage tube. Therefore, the chest drainage tube can be passed through the side hole mechanism 400 through the setting of the side hole mechanism 400 to avoid skin pressure and facilitate observation; by setting the shoulder strap 110, the up and down movement of the fixing belt 100 can be reduced when the patient is active, thereby improving the fixation effect on the sternum, and the shoulder strap 110 can be set to be adjustable in length to facilitate fitting patients of different body shapes.

[0027] It should be noted that, when the first airbag mechanism 200 is not inflated, the cotton cloth 120 can be understood to be in contact with the fixing belt 100, and the provision of the cotton cloth 120 can prevent the airbag from directly contacting the skin, thereby improving air permeability and increasing wearing comfort.

[0028] In the embodiments of the present invention, Figure 1-4 As shown, the first airbag mechanism 200 includes: an airbag ring 210, a first airbag block 220, a first inflation hole 230 and a first sealing plug 240; the airbag ring 210 is arranged at the edge of the containing layer 130; multiple first airbag blocks 220 are symmetrically arranged on both sides of the containing layer 130, and the first airbag blocks 220 are connected to the airbag ring 210; the first inflation hole 230 is arranged on the fixing belt 100, and the first inflation hole 230 is located at the position of the airbag ring 210; the first sealing plug 240 is arranged in coordination with the first inflation hole 230.

[0029] In the embodiments of the present invention, Figure 1-4 As shown, the first airbag block 220 is in the shape of a right triangle.

[0030] When it is necessary to inflate the airbag ring 210 and the first airbag block 220, first remove the first sealing plug 240, then connect an external inflation device to inflate the airbag ring 210. Since the plurality of first airbag blocks 220 are respectively connected to the airbag ring 210, the plurality of first airbag blocks 220 are inflated at the same time as the airbag ring 210 is inflated, so that they expand and press against the patient's body surface until the tightness is adjusted to the optimal position and then stop inflating. Then install the first sealing plug 240 on the first inflation hole 230. The first airbag mechanism 200 is symmetrically arranged up and down, so that the fixing device is suitable for patients of different body shapes. If the patient is thin (less abdominal meat), the above-mentioned In this way, the first airbag mechanism 200 below is inflated, thereby forming an inverted trapezoidal structure on the inner side of the fixing belt 100, so as to reduce the situation that the upper part is too tight while the lower part is still relatively loose; if the patient is fatter (more belly fat), the first airbag mechanism 200 above can be inflated in the above way, thereby forming a trapezoidal structure on the inner side of the fixing belt 100, so as to reduce the situation that the lower part is too tight while the upper part is still relatively loose; if the patient has a well-proportioned body (the dimensions of the ribs and the abdomen are almost the same), there is no need to inflate the first airbag mechanism 200, and the two ends of the fixing belt 100 can be directly fixed with Velcro, so the fixing device can be suitable for patients of different body shapes.

[0031] In the embodiments of the present invention, Figure 1-4 As shown, the second airbag mechanism 300 includes: a second airbag block 310, a second inflation hole 320 and a second sealing plug 330; the second airbag block 310 is arranged in the containing layer 130, and the second airbag block 310 is fixedly connected to the cotton cloth 120; the second inflation hole 320 is opened on the fixing belt 100, and the position of the second inflation hole 320 corresponds to the position of the second airbag block 310; the second sealing plug 330 is arranged in cooperation with the second inflation hole 320.

[0032] The second airbag block 310 is set on the patient's chest, and then the second sealing plug 330 is removed. Then, an external inflation device is connected to the second inflation hole 320, and then the second airbag block 310 is inflated to make it expand and press against the patient's body surface. The inflation is stopped until the tightness is adjusted to the optimal position, and then the second sealing plug 330 is installed on the second inflation hole 320. Then, the second airbag block 310 exerts pressure on the patient's body to achieve the purpose of adjusting the tightness. There is no need to tear off the Velcro and then stick it again to try to adjust the tightness multiple times. It is easy to use, and the airbag expands slowly, and the pressure on the patient's body gradually increases. When the tightness is appropriate, the inflation can be stopped, thereby achieving the purpose of accurately adjusting the tightness.

[0033] In the embodiments of the present invention, Figure 1-4 As shown, the side hole mechanism 400 includes: a side hole 410 and a snap button 420 ; the side hole 410 is opened on one side of the fixing belt 100 ; and at least one snap button 420 is arranged on the opposite side of the side hole 410 .

[0034] Since a chest drainage tube is usually routinely left in place after cardiac thoracotomy, when the fixation belt 100 is worn, the chest tube is directly pressed under the fixation belt 100, which poses a risk of pressure injury and is not conducive to directly observing the outlet of the wound drainage tube. Therefore, the chest drainage tube can be passed through the side hole 410 through the setting of the side hole 410 to avoid skin pressure and facilitate observation. When the side hole 410 is not in use, the two ends of the side hole 410 can be fixed by the snap fastener 420 to avoid affecting the tightness of the package.

[0035] In the embodiments of the present invention, Figure 1-4 As shown, it also includes: ventilation holes (not shown in the figure), and multiple ventilation holes are opened between the multiple first airbag blocks 220.

[0036] Since the fixing belt 100 needs to be worn all day after thoracotomy, ventilation holes are provided between the plurality of first airbag blocks 220 to improve the air permeability of the fixing belt 100 and increase the wearing comfort.

[0037] It should be noted that the specific model and specifications of the button 420 need to be selected and determined based on the actual specifications of the device, so they will not be described in detail.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
