Detailed Description
The utility model will be further elucidated and described with reference to the drawings and the detailed description. The technical features of the embodiments of the present invention can be combined correspondingly without mutual conflict.
Referring to fig. 1, the radial artery compression hemostat based on human anatomy shape provided by the present invention includes two major parts, namely a pressure hemostat 1 and a pressure sensor 4, and the connection relationship and structure of the components will be described in detail below.
The pressure hemostat 1 is of an annular roll structure, and a certain annular gap is reserved in the middle of the pressure hemostat 1. The annular gap is used as an inner ring gap for wrapping the wrist to be treated in a surrounding way so as to achieve the purpose of compressing the radial artery to stop bleeding. Since the pressure hemostat 1 has a roll-like structure, it has one end, i.e., an active end, at the outermost side thereof, and the active end can slide along the secondary outer side of the pressure hemostat 1. The movable end and the contact section of the pressure hemostat 1 which is attached and slides are also provided with a fixing piece which can fixedly connect the movable end and the pressure hemostat. In practical application, the pressure hemostat 1 is made of flexible material and can be made of tourniquets; the fixing member between the movable end of the pressure hemostat 1 and the outer side of the pressure hemostat 1 may be configured as an adhesive tape, and the tightness of the wrist around which the pressure hemostat 1 is fixed may be adjusted by the adhering position of the adhesive tape.
Because the pressure hemostat 1 is a continuous integral structure, when the movable end slides along the secondary outer side surface, the size of the inner ring gap at the middle part of the pressure hemostat 1 can be correspondingly changed, namely, the perimeter length of the inner ring gap can be correspondingly adjusted, thereby being capable of adapting to the wrist thickness conditions of different patients.
The pressure that needs to use when considering every patient hemostasis by compression is not of uniform size, and patient's wrist size is different moreover, consequently sets up the demonstration structure that can audio-visually roughly show the wrist elasticity degree of encircleing in the outside of pressure hemostat 1, specifically as follows:
a plurality of pressure value marks 5 are provided on the outer side of the pressure hemostat 1 in the circumferential direction, and the pressure value marks 5 are all numbered in sequence at the same pitch. Still be equipped with index mark 6 on pressure hemostat 1, index mark 6 can show the elasticity degree that pressure hemostat 1 encircles the wrist through instruction pressure numerical value sign 5.
In practical application, the pressure value marks 5 can be set to be 9, and the pressure value marks are numbered from small to large sequentially from the active end by 1-9. Meanwhile, a plurality of holes with the same interval can be formed in the outer side of the pressure hemostat 1 along the circumferential direction, a plurality of pressure numerical value marks 5 are arranged on the outer side of the pressure hemostat 1 below the holes along the circumferential direction, and the interval between every two adjacent pressure numerical value marks 5 is the same as that between every two adjacent holes. The hole can also slide relative to the pressure value marking 5 when the movable end slides along the outside. Fix in the indicateing sign 6 beside arbitrary hole, regard this hole as the instruction hole, consequently, when adjusting pressure hemostat 1 and encircle wrist elasticity, the bottom in instruction hole just can demonstrate different pressure numerical value mark 5 to can be roughly know the elasticity that pressure hemostat 1 encircles the wrist this moment.
In order to more accurately and clearly display the pressure at the radial artery during hemostasis by compression, as shown in fig. 2, an interlayer may be disposed inside the pressure hemostat 1 located at the radial artery compression position, the interlayer is used for placing and fixing the pressure sensor 4, and the pressure sensor 4 can conduct the pressure change at the radial artery compression position. As shown in fig. 3, the pressure sensor 4 is connected to the signal processing module 2 through a wire, and the signal processing module 2 is connected to the pressure display terminal 3 through a wire. When the hemostat is applied, the pressure sensor 4 is placed in the interlayer, the position of the interlayer is placed at the radial artery compression position, the pressure sensor 4, the signal processing module 2 and the pressure display terminal 3 are respectively communicated through leads, and the specific pressure value at the radial artery compression position is displayed through the display screen, so that the pressure at the radial artery compression position during hemostasis by compression at that time can be obtained, and the pressure given by the hemostat during circumferential dressing can be adjusted according to the observation of whether the wound is stopped, the limb end circulation and the feeling of a patient.
The size of the pressure sensor 4 is relatively small, the pressure sensor can be conveniently and fixedly placed in the interlayer to sense pressure change, and meanwhile, the pressure sensor can be taken out of the interlayer when not in work, so that the parts are convenient to clean and replace. In this embodiment, the pressure sensor 4 can be set to be similar to a coin, that is, the cross section of the pressure sensor 4 is circular, the diameter of the cross section is 20-25 mm, and the thickness is 1-3 mm. In addition, the pressure display terminal 3 may be a display screen installed with pressure monitoring software, such as a PC or an IPAD.
Examples
After a certain patient coronary angiography, the compression hemostat provided by the utility model is used for surrounding the wrist of the patient, and the sliding position between the movable end and the outer side is adjusted, so that enough pressure is provided for compressing the wound until no bleeding is observed, and the compression tourniquet is fixed. The pressure sensor 4 is placed in the interlayer of the pressure hemostat 1, and the tail end of the pressure sensor 4 is connected with the signal processing module 2. At this time, the pressure 210mmHg is displayed on the display screen, but the actual radial artery invasive systolic pressure of the patient is 130mmHg (which is monitored and recorded in the interventional operation), which indicates that the pressure given by the compression hemostasis at this time is too large, and the tourniquet should be properly loosened so as to conform to the actual condition of the patient.
The above-described embodiments are merely preferred embodiments of the present invention, which should not be construed as limiting the utility model. Various changes and modifications may be made by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present invention. Therefore, the technical scheme obtained by adopting the mode of equivalent replacement or equivalent transformation is within the protection scope of the utility model.
