[0029] In order to make those skilled in the art better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0030] like Figure 1-4 As shown, a medical pressing hemostasis device includes a valve seat 1 and an air bag belt 2, one end of the air bag belt 2 is fixed on the valve seat 1, and the other end is wrapped around the wrist arm and fixed to the valve seat 1 to form a circular ring structure;
[0031] The airbag belt 2 is provided with a grid-shaped elastic rib frame, which is limited by the pulling of the grid-shaped elastic rib frame, so that the airbag belt 2 expands in a circular structure;
[0032] The valve holder 1 is communicated with an external inflatable device, so that a predetermined air pressure is maintained in the airbag band 2 inflated in an annular structure for squeezing the wound to stop bleeding.
[0033] Specifically, the cross-section of the airbag belt 2 in the embodiment after inflation is a rectangular structure (such as Figure 4 It can be known), and the valve seat 1 is a hard plastic material, and its function is to be used to fix one end and the other end of the airbag belt 2, and inflate through one end alone or at the same time. Further, one end of the air bag belt 2 in the embodiment is first fixed on the valve seat 1, then wrapped around the patient's wrist arm and then fixed on the valve seat 1, so that the entire air bag belt 2 is in a ring-shaped structure after being inflated, After inflation, it can be firmly pressed on the wound of the patient, and the wound can be compressed by inflating the air bag belt 2 to ensure that the pressure test pressure remains in a moderate state.
[0034] It should be noted that the airbag belt 2 is made of medical rubber, which can be directly inflated and expanded to press the wound, or a medical gauze covering the wound can be placed in advance at the wound, and finally the inflated airbag belt 2 is used to press the wound to stop bleeding (the The width needs to completely cover the medical gauze covering the wound), and in order to realize the positioning of the medical gauze placed on the wound, the inner side of the airbag band 2 having a circular structure after being fixed needs to be close to the patient's wrist.

Because the airbag belt 2 in the embodiment has a long rectangular structure, and the inflation method is to inflate through one end alone or at the same time, so when inflating through the valve seat 1, the air pressure of the air intake end of the airbag belt 2 must be inflated. It is larger than the part far away from the air inlet end, which causes the problem of uneven air pressure inside the airbag belt 2, and the problem of bulging, which leads to the cheap pressure applied by the device to the wound, and even the wound cannot be squeezed. The grid-shaped elastic rib frame in the embodiment is pulled during the inflation process, when the grid-shaped elastic rib frame close to the air intake end is pulled so that it expands to a predetermined pulling limit of the grid-shaped elastic rib frame, then the grid-shaped elastic rib frame is stretched. Under the pulling force, the rest of the airflow will flow into the place where the grid-like elastic rib frame is not fully stretched, so that the entire airbag belt 2 will expand evenly after being inflated to the predetermined air pressure, and there will be no local bulging. question.

To discharge, the staff can stop the inflation at this time, and when the gas pours to a predetermined value, the exhaust will be stopped. Thus, it is ensured that the pressure applied to the wound after the airbag belt 2 is inflated remains in a moderate state. Further, the one-way intake valve connecting seat 12 in the above-mentioned embodiment (only for air intake, not for air outlet), its function is to be threadedly installed in the threaded seat, and fixed to the intake lip 23 extending into the threaded seat. , so that the one-way intake valve connecting seat 12 communicates with the raised portion 21 .
[0045] The external inflatable device is a conventional inflatable device known to those skilled in the art, and is not detailed here.
[0046] Furthermore, in the embodiment, an external inflatable device is used to inflate the protruding portion 21 of the airbag belt 2 through the one-way intake valve connecting seat 12, and is pulled by the mesh-shaped elastic rib frame, so that the entire airbag belt 2 is kept inside. With relatively uniform inflation, when the airbag belt 2 expands to the pulling limit of the vertical elastic connecting rib 3 and the horizontal elastic connecting rib 8, the continuously replenished gas will drive the elastic rubber provided on the inner wall of the central groove of the groove portion 22. The block 5 is squeezed, so that the elastic rubber block 5 expands to a hemispherical structure with the side wall of the groove portion 22 as the horizontal plane after inflation. The elastic rubber block 5 of the hemispherical structure will squeeze into the gap 4 . As the elastic rubber block 5 continues to expand, it will squeeze the push-type one-way air valve 6 so that it is triggered to discharge gas due to the squeeze. At this time, the staff stops using the external inflatable equipment, and when the gas inside the air bag belt 2 is discharged to the elastic After the rubber block 5 is shrunk until it no longer squeezes the push-type one-way air valve 6, the exhaust is stopped.

[0048] As another embodiment further provided by the present invention, the push-type one-way air valve 6 includes arc-shaped flaps 61 ( figure 2 shown state), an elastic member 62 is provided in the raised portion 21, the elastic member 62 is fixed at the arc top of the arc-shaped petal 61, and the two elastic members 62 are used to keep the two arc-shaped petals 61 in the semicircular structure The elastic rubber block 5 of the hemispherical structure pushes against the elastic member 62, and the elastic member 62 squeezes to make the contact part with the arc-shaped petal 61 concave, so that the contact part of the two arc-shaped petals 61 is separated to form an exhaust port. Specifically, in the embodiment, the push-type one-way air valve 6 is composed of arc-shaped flaps 61 that are relatively distributed and combined in a semi-circular structure. One side of the lip 23 is on the inner wall, and the other end is in contact with each other to form the "arc top" of the semicircular structure. Further, in the embodiment, an air intake arc seat 25 is also arranged in the convex portion 21. The air intake arc seat 25 has a specific semicircular structure, and the side wall of the semicircular structure is provided with a plurality of air holes. The air arc seat 25 is used to intercept the air entering the air intake lip 23 to prevent the airflow from directly impacting the "arc top", which will deform the "arc top" under the impact of air pressure and damage the seal.
[0049] Furthermore, in the embodiment, an elastic member 62 is also provided, the elastic member 62 maintains the vertical portion and the inclined portion, the vertical portion and the convex portion 21 are internally linked, and the inclined portion is connected with the side wall of the arc-shaped petal 61 . In a specific embodiment, the one-way intake valve connecting seat 12 is threadedly installed in the threaded seat, and is fixedly extended to the intake lip 23 in the threaded seat, so that the one-way intake valve connecting seat 12 is connected to the raised portion 21 Pass. Then the convex parts of the groove part 22 are inserted between the outer walls on the opposite sides of the convex part 21 and the inner walls on the opposite sides of the U-shaped holder 11 to form an equidistant space, and the convex part 21 is located at the center of the groove part 22. groove. The external inflatable equipment is used to inflate the convex portion 21 of the airbag belt 2 through the one-way air intake valve connecting seat 12, and is pulled by the grid-shaped elastic rib frame, which will keep the entire airbag belt 2 relatively evenly inflated. When the airbag belt 2 expands to the pulling limit of the vertical elastic connecting rib 3 and the horizontal elastic connecting rib 8, the continuously replenished gas will drive the elastic rubber block 5 provided on the inner wall of the central groove of the groove portion 22 to squeeze, so that After the elastic rubber block 5 is inflated, it expands to a hemispherical structure with the side wall of the groove portion 22 as the horizontal plane. The block 5 will be squeezed into the notch 4, so as to realize the clamping. As the elastic rubber block 5 continues to expand, it will push against the inner recess of the inner convex portion 21 of the elastic rubber sealing web 41, and finally the elastic rubber sealing web 41 pushes the two elastic members 62 toward the center. 62 is squeezed to make the contact part with the arc-shaped petals 61 concave, so that the "arc top" is split to form a one-way air hole, and the air flow inside the air bag belt 2 is discharged into the interior of the two arc-shaped petals 61 through the one-way air hole, Then, it is discharged from the air outlet 24 opened on the convex part 21 . When the air in the airbag belt 2 is exhausted until the elastic rubber block 5 shrinks and no longer squeezes the elastic member 62, the elastic member 62 is automatically reset, so that the "arc top" is re-healed and the one-way air hole is closed.
[0050] As the preferred embodiment further provided by the present invention, such as figure 2 It can be seen that the convex portion 21 is provided with an arc-shaped support member 7, and the two arc-shaped petals 61 are attached to the side wall of the arc-shaped support member 7 to maintain the semicircular structure; and a recessed portion is preset on the arc-shaped support member 7. 71. The concave portion 71 is used for the elastic member 62 to be squeezed so that the contact portion with the arc-shaped petal 61 is located within it to move. Specifically, in order to ensure that the continuous expansion of the elastic rubber block 5 will push against the inner recess of the inner convex portion 21 of the elastic rubber sealing web 41, and finally the elastic rubber sealing web 41 pushes the two elastic members 62 toward the center. During this process , the elastic member 62 is pressed to make the contact part with the arc-shaped petal 61 concave, so that the "arc top" is split to form a one-way air hole. In the embodiment, an arc-shaped support member 7 is arranged on the inner side of the arc-shaped petal 61 to be in contact with the arc-shaped petal 61, and when the elastic member 62 moves toward the center, in the process, the elastic member 62 is squeezed to make it contact with the arc-shaped petal 61. The contact portion is concave, and the concave is located in the concave portion 71 on the arc-shaped support 7, so as to realize the technical difficulty of constraining the opening size of the unidirectional air hole formed by the cracking of the "arc top". When the air in the airbag belt 2 is exhausted until the elastic rubber block 5 is contracted and no longer squeezes the elastic member 62, the elastic member 62 is automatically reset, so that the "arc top" is re-healed and the one-way air hole is closed.
[0051]As a further technical solution of the present invention, in the embodiment, after the airbag belt 2 is inflated to a predetermined size, the continuous expansion of the elastic rubber block 5 will push the inner recess of the convex portion 21 of the elastic rubber sealing web 41, and finally make the elastic rubber sealing web 41 pushes the two elastic pieces 62 toward the center. During this process, the elastic pieces 62 squeeze to make the contact part with the arc-shaped flap 61 concave, so that the “arc top” is split to form a one-way air hole for pressure relief. In order to facilitate the medical staff to discover and close the external inflatable equipment in time, the present invention also provides a warning mechanism. This embodiment is as follows, the arc top of the arc-shaped support member 7 is provided with a through hole, and the two arc-shaped flaps 61 are subjected to elastic members. 62 is connected to the through hole when the pressing contact part is separated. Specifically, when the "arc top" splits to form a one-way air hole for pressure relief, the airflow passes through the through hole, and the strong airflow directly hits the through hole, and a sound is generated when the air velocity is tangent, thus prompting the medical staff to turn off the external inflatable equipment. .
[0052] As the preferred embodiment further provided by the present invention, such as figure 2 As shown, the standing whistle 9 is installed at the through hole, and the arc top of the arc-shaped support 7 is a concave to form a funnel-shaped cavity. When a strong airflow directly impacts the cavity, the airflow enters through the wide opening of the cavity. Then it is discharged from the narrow port, and the airflow impacts the whistle 9 to make the sound louder.
[0053] Certain exemplary embodiments of the present invention have been described above by way of illustration only, and it is needless to say that those skilled in the art may The described embodiments are modified. Accordingly, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
