[0027] like Figures 1 to 5 As shown, an embodiment of the utility model provides a venous hemostat, which mainly includes a main body 1 and an air bag 22.

[0028] The main body 1 is annular, and a receiving space is formed inside for the arm of a person who needs hemostasis to pass through. In this embodiment, the main body 1 includes a first semi-annular member 11 and a second semi-annular member 12. The first semi-annular member 11 and the second semi-annular member 12 are hinged to each other through a rotating shaft 13, and are used to open the receiving space for the arm to pass through the opening, so as to facilitate the arm of the person who needs hemostasis to pass through. The first semi-annular member 11 and the second semi-annular member 12 are further extended outward at the hinge to form a grip 14 for the operator to take and open. Through the grip 14, the operator can rotate the first semi-annular member 11 and the second semi-annular member 12 with one hand, thereby opening the main body 1 (such as Figure 5 The two grips 14 are staggered with each other, and the width is slightly less than half of the width of the main body. Of course, the other end of the first semi-annular member 11 and the other end of the first semi-annular member 12 (the other end opposite to the hinge) can also be provided with a locking structure such as a buckle (not shown) to prevent the first semi-annular member 11 and the first semi-annular member 12 from opening after being compressed.

[0029] The airbag 2 is arranged inside the main body 1 and is used to connect to an inflating device (not shown). The airbag 2 is inflated by the inflating device to compress the arm to block the venous blood flow. A tourniquet slot 21 is provided inside the airbag 2 for inserting a disposable tourniquet 3 so that the disposable tourniquet 3 is attached to the skin surface of the arm (such as Figure 4 In this embodiment, there are two airbags 2, which are respectively located on the inner sides of the first semi-circular member 11 and the first semi-circular member 12. Two tourniquet slots 21 are provided on the inner side of each airbag 2.

[0030] In this embodiment, a plurality of (8 in this embodiment) infrared sensors 4 for measuring arm circumference are also provided on the inner side of the main body 1. The infrared sensor 4 is used to connect the inflation device to transmit the measured arm circumference data to the inflation device, and the inflation device inflates the airbag 2 according to the arm circumference data. Specifically, the inflation device obtains the inflation amount of the airbag 2 based on the inner size of the airbag 2, the arm circumference size, and the degree of compression of the arm. In simple terms, it can be inflation amount = (inner size of the airbag - arm circumference size + compression distance of the arm) * cross-sectional area of ​​the airbag 2. The pressure is preferably 180-200mmgh.

[0031] In this embodiment, a pressure sensor 5 for real-time detection of the pressure applied to the arm is provided between the airbag 2 and the main body 1. The pressure sensor 5 is used to connect to the inflation device to transmit the measured pressure data to the inflation device, and the inflation device inflates the airbag 2 according to the pressure data. The pressure sensor 5 is used to form real-time feedback, so that the airbag 2 can be inflated more accurately.

[0032] In this embodiment, the preliminary data of the inflation amount is obtained by the infrared sensor 4 for inflation, and the pressure sensor 5 is used for feedback during the inflation process to detect the pressure in real time, so that the inflation process is fast and accurate. Of course, in other embodiments, only one of the infrared sensor and the pressure sensor can be set as needed. For example, if fast inflation is mainly required, only the infrared sensor can be set, and if accuracy is required and based on cost considerations, only the pressure sensor can be set. It is also possible to not set any sensor / sensor and perform the inflation operation by manual pressing.

[0033] The inflation device is different depending on whether the sensor / transducer is provided and the type. If the sensor / transducer is not provided, the inflation device is manual. If the sensor / transducer is provided, the inflation device is connected to the airbag 2, the infrared sensor and / or the pressure sensor to inflate the airbag 2 according to the arm circumference data and / or the pressure data measured by the infrared sensor. Because the inflation device can be externally connected (usually externally connected) and existing products can be used (it can be similar to an electronic sphygmomanometer, an inflation device with an air pump and a display screen), it can be independent of the venous hemostat. In other words, the venous hemostat including the main body 1 and the airbag 2 can be produced and sold separately, and then cooperated with the inflation device when used.

[0034] The disposable tourniquet 3 can also be an existing product. The disposable tourniquet 3 is inserted into the tourniquet slot 21 before the hemostasis operation, and the end is fixed to form a ring for sticking to the skin surface of the arm, so that one person can use it, which meets the safety requirements of medical supplies. Like the inflation device, the disposable tourniquet 3 can be independent of the venous hemostat. In other words, the venous hemostat including the main body 1 and the airbag 2 can be produced and sold separately, and then used in conjunction with the disposable tourniquet.

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
