Thus, the exemplary term "above" can include both "above" and "below" orientations. The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly.

[0041] As Figure 1 And Figure 2 As shown in the figure, the in-vitro sternum fixing device comprises a fixing belt 1 for mainly fixing the position of the patient's sternum and a bandage 2 which is wrapped around the back of the patient and is adjustably connected to the other end of the fixing belt 1. The fixing belt 1 is sutured to one end of the bandage 2, and the other end of the fixing belt 1 is sutured to the upper side of a side fixing rod 3, and the bandage 2 is detachably connected around the side fixing rod 3.

[0042] The bandage 2 passes through the bottom of the side fixing rod 3 and wraps around the upper side of the side fixing rod 3, and the end of the bandage 2 is fixed by magic tape between the outer wall of the bandage 2. The connection position of the magic tape can conveniently adjust the tightness of the bandage 2 and improve the comfort of the patient.

[0043] Further, the fixing belt 1 and the bandage 2 are both made of flexible cloth with good air permeability, which not only meets the comfort requirement of the patient wearing it after the operation, but also solves the defect that the skin is itchy or injured by the hard fixing belt after using the cloth chest band in clinical practice.

[0044] For example, the fixing belt 1 and the bandage 2 are made of nylon material, which has the advantages of flexibility, comfort, air permeability and durability.

[0045] The bandage 2 has a certain width, which avoids the defect that the existing technology relies on long rope binding type fixing and easily injures the patient.

[0046] By setting the connection position of the bandage 2 at the position under the armpit of the patient through the side fixing rod 3, the patient can conveniently operate the fixing himself, especially the patient can adjust the tightness at any time according to his own comfort, so as to avoid the occurrence of pressure sores caused by long-term over-tightness; on the contrary, it also avoids the bandage 2 being too loose and unable to play the effect of fixing the sternum.

[0047] In order to improve the fixing effect, especially to avoid the fixing belt 1 from sliding down.

[0048] A back strap 4 is sutured and fixed on the upper side of the bandage 2, and an upper fixing rod 5 is sutured and fixed on the upper side of the fixing belt 1, and the back strap 4 is wrapped around the shoulder of the user and detachably connected to the upper fixing rod 5.

[0049] The more the number of fixing belts 1 is, the larger the adjustable range is. The fewer the number of fixing belts 1 is, the faster the connection is. Therefore, the fixing belt 1 is provided with at least three, and the adjacent fixing belts 1 are sutured and connected by an elastic belt 6. The adjacent fixing belts 1 can have a certain deformation space, that is, within the elastic range of the elastic belt 6, the adjacent fixing belts 1 can relatively dislocate and move, so as to meet the comfort adjustment of the patient. In order to ensure the fixing effect, when the deformation space of the elastic belt 6 is exceeded, the adjacent fixing belts 1 will be pulled, so as to ensure the fixing effect of the sternum of the patient.

[0050] In order to have an adjusting force between the fixed bands 1, improve the comfort. The lower part of the uppermost fixed band 1 is sewn and connected with a lower fixed rod 7, and the lower part of the lowermost fixed band 1 is sewn and connected with an auxiliary band 8, which is detachably connected around the lower fixed rod 7. Through the connection between the auxiliary band 8 and the lower fixed rod 7, the comfort of the patient is improved.

[0051] In order to easily scratch the skin with the hard connection structure, and also need to support a certain shape to avoid the deformation of the fixed band 1, which affects the use effect. The side fixed rod 3, the upper fixed rod 5 and the lower fixed rod 7 respectively include a circular rod 01 of hard material and a connecting cloth 02 of flexible cloth. The upper side of the connecting cloth 02 is wrapped outside the outer wall of the circular rod 01, and the connecting cloth 02 extends out of the two ends of the circular rod 01 by a certain length, and the two ends of the connecting cloth 02 extending out of the circular rod 01 are sewn and fixed on the upper surface of the fixed band 1. A gap is left between the circular rod 01 and the surface of the fixed band 1, which can satisfy the smooth passing of the bandage 2. Through the hard support of the circular rod 01, the deformation of the bandage 2 is avoided, so that the bandage 2 can be guaranteed to be attached to the surface of the patient's skin, and the comfort of the patient is improved.

[0052] In order to interact with the ringing bandage 2, ensure that the bandage 2 is completely unfolded, avoid bending and scratching the back of the patient, especially when the patient is lying down, the bent bandage 2 seriously affects the comfort of the patient. Each fixed band 1 is connected with a bandage 2, and the adjacent bandages 2 are sewn and connected with a connecting band 9. The connecting band 9 pulls to ensure that the bandage 2 is in a completely unfolded state.

[0053] Since it is not easy to identify which side fixed rod 3 the bandage 2 corresponds to after passing around the back of the patient, each bandage 2 and side fixed rod 3 is provided with different colors, or each bandage 2 and side fixed rod 3 is provided with different labels. In clinical practice, patients and their families all feedback that it is extremely inconvenient to use, each fixed band 1 and its corresponding bandage 2 are marked with the same Arabic numerals, and the operation steps are changed to a visual digital guidance mode, so that beginners can use it at a glance, solving the problem that multiple learning still cannot use in the traditional chest band use process, and also reducing the workload of clinical medical staff.

[0054] In order to ensure the connection effect and avoid using too much, the elastic band 6 is twisted during the mutual displacement of the fixed bands 1, which affects the comfort of the patient. In this embodiment, three elastic bands 6 are provided between adjacent fixed bands 1, which are connected at the two ends and the middle position of the fixed band 1.

[0055] In order to further increase the ventilation effect, especially the incision wound position of the chest needs more ventilation to improve the recovery effect of the wound. The middle of the fixed band 1 is provided with a ventilation slot 10; the wound position of the patient is not covered to the maximum extent, the ventilation effect of the wound position is improved, which is beneficial to the recovery of the wound of the patient.

[0056] In order to avoid the effect of the straps 4 on the air-permeable slots 10, which will deform the air-permeable slots 10 and affect the overall shape of the fixing belt 1, thus reducing the fixing effect and affecting the comfort of the patient. The straps 4 and the upper fixing rods 5 are provided with two respectively, and the length of the air-permeable slots 10 is less than the distance between the two straps 4. Therefore, the pulling force of the straps 4 will not act on the air-permeable slots 10, so as not to deform the air-permeable slots 10.

[0057] Since the fixing belt 1 is made of flexible material, the fixing belt 1 needs to be fully laid out to increase the force bearing area on the patient and improve the fixing effect. The keel plates 11 are sewn at the two ends of the fixing belt 1, and the keel plates 11 are completely covered inside the flexible cloth of the fixing belt 1. The fixing belt 1 is arranged at the two ends, so that the keel plates 11 are located at the relatively flat underarm position of the patient, reducing the possibility of the keel plates 11 hurting the patient and improving the use effect of the whole product.

[0058] Preferably, the length of the keel plate 11 is less than or equal to the width of the fixing belt 1, so as to ensure that the fixing belt 1 completely covers the keel plate 11. The width of the keel plate 11 is 3-5 cm, and the width of the keel plate 11 is less than the thickness of the chest position of the human body.

[0059] The above is only a preferred embodiment of the present application, and is not intended to limit the protection scope of the present application.
