Detailed Description
The application is described in further detail below with reference to fig. 1-5.
The embodiment of the application discloses a radial artery compression hemostasis device. Referring to fig. 1, the radial artery compression hemostasis device comprises a connecting ring 1 and a presser 2.
The connecting ring 1 is the prior art, and can adopt the mode mentioned in the background art document, or can adopt a fastening tape (similar to a bandage for blood pressure measurement) or a similar belt structure. And thus will not be described in detail. The difference is that the connecting ring 1 of the present application has the enlarged fitting portions 3 formed at both ends in the axial direction (arm length direction) of the connecting ring 1, and the enlarged fitting portions 3 are integrally formed with the connecting ring 1, as compared with the conventional connecting ring 1. The enlarged fitting portion 3 increases the contact area of the hemostatic device with the limb, improves the stability of fixation, and reduces displacement of the device during use.
The presser 2 is fixed on the connecting band, and the position of the presser 2 is just opposite to (face to face with) the enlarged fitting portion 3, which can be understood that the presser 2 is located on one side of the wrist and the enlarged fitting portion 3 is located on one side of the back of the hand.
The presser 2 is arranged on the connecting ring 1 and applies pressure to the puncture part, the presser 2 comprises an observation chamber 4, a pressing piece 5 and an operating piece, the observation chamber 4 is positioned at the periphery of the pressing piece 5 and is transparent, and the operating piece controls the pressing piece 5 to apply pressure to the puncture part. Wherein the viewing chamber 4 can be fixed to the connecting band by means of adhesive, the connecting band being of a soft material or a flexible material having a certain deformability, so as to adjust the size of the connecting band. The observation chamber 4 is specifically a square frame structure, one side of the square frame, which is close to the limb, is through, and the other end of the square frame is closed. The operation room comprises a screw rod 6 and a sliding block 7, wherein the screw rod 6 penetrates through the closed end of the square frame and is in threaded connection with the square frame. The slide block 7 is attached to at least part of the inner wall of the square frame so that the slide block 7 can only slide. The end of the screw rod 6 is in rotary connection and fit with the slide block 7. So that the screw 6 can only rotate relative to the slide 7. Specifically, the end of the screw rod 6 forms a rotating hole with the diameter larger than that of the end of the screw rod 6, and the sliding block 7 is internally provided with a rotating hole with the same size as that of the end, so that when the screw rod 6 rotates, the sliding block 7 can only be pressed or loosened along with the translation of the screw rod 6. The slider 7 and the pressing member 5 may be directly connected or indirectly connected. The mode that this scheme adopted is direct connection, and press piece 5 is connected through the mode of bonding with slider 7, presses piece 5 to be the PP rubber slab in this scheme of preference.
In order to accelerate hemostasis or provide a more comfortable pressing mode, a temperature control part is added in the scheme, and the temperature control part specifically comprises a semiconductor refrigeration plate 15, a temperature sensor, a controller 14 and a power supply 11.
Wherein the semiconductor refrigeration plate 15 is bonded to the slider 7, and the slider 7 is made of a material having good heat conduction properties, such as polyetheretherketone, modified polypropylene (modified with a heat conduction material). A first conductive member 8 and a second conductive member 9 are provided on the inner wall of the observation chamber 4. The first conductive element 8 and the second conductive element 9 are typically fixed to the inner wall of the viewing chamber 4 by means of adhesive. In this embodiment, the first conductive member 8 and the second conductive member 9 are both strip-shaped structures. A power supply groove 10 for placing a power supply 11 is formed on one side of the connection ring 1, which is positioned in the observation chamber 4, and the power supply 11 is a storage battery or a dry battery, so that a patient can walk at will without being required to be positioned at a specific position. In order to facilitate the battery taking out and replacing, notches 12 are formed at both ends of the battery groove so as to facilitate the battery taking out. One electrode of the power supply 11 is connected with the first conductive member 8, the other electrode of the power supply 11 is connected with the second conductive member 9, one end of the semiconductor refrigeration plate 15 is in sliding contact with the first conductive member 8 and keeps electrical connection, and the other end of the semiconductor refrigeration plate 15 is in sliding contact with the second conductive member 9 and keeps electrical connection.
The display 13 and the controller 14 are both located on the other side of the viewing chamber 4, so that the structure is balanced. The power supply 11 supplies power to both the display 13 and the controller 14. The temperature sensor 20 is also located on the inner wall of the observation chamber 4, and the temperature sensor 20 in this embodiment is arranged in a long strip shape and extends along the sliding direction of the pressing member 5, so as to ensure that at least a part of the pressing member 5 is always in contact with the temperature sensor during the moving process. The power supply 11 supplies power to the temperature sensor through a wire, the wire can be embedded in the observation chamber 4, and the wire can be put in together when the observation chamber 4 is injection molded. The wires between the power supply 11 and the first conductive member 8 and the second conductive member 9 may be pre-buried or may be connected later.
Except the semiconductor refrigeration plate 15, the first conductive member 8 and the second conductive member 9, all the other devices which do not normally need to be electrified are processed by plastic materials such as PP. The plastic material generally has better corrosion resistance, is not easy to rust or damage due to contacting with substances such as moisture, disinfector and the like in the daily use and cleaning maintenance process, can prolong the service life of the device and reduce the maintenance cost. Wherein the observation window is generally made of heat-insulating materials, such as PP modified materials (heat-insulating materials are added into PP), rigid polyurethane foam plastics, extruded polystyrene foam plastics (XPS board) and the like.
To reduce the risk, a protective patch 19 is also typically applied after the compression is completed. For convenience and safety, in this embodiment, two adhesive parts 16 are formed at two ends of the pressing member 5 along the arm length direction. The adhesive portion 16 is generally an adhesive surface on only the side close to the arm, and a release paper 17 is attached to the adhesive surface. The lower surface of the adhesive portion 16 is flush with the lower surface of the pressing member 5 (the lower surface refers to the surface close to the arm), and when in use, the release paper 17 is peeled off first, and the protective patch 19 is adhered to the adhesive portion 16, and the protective patch 19 is typically a skin protective patch 19 with a hemostatic function, such as a band-aid. The adhesive-free side of the protective sheet 19 is bonded to the adhesive portion 16, and the adhesive-free side faces the skin. When the compression is finished, the protector 19 remains on the skin.
In order to facilitate the continued adherence of the protective patch 19 to the skin, the adhesive portion 16 is detachably mounted to the presser 5. The adhesive portion 16 can thus be separated from the pressing element 5, so that the adhesive portion 16 remains on the skin together with the protective patch 19. Specifically, the adhesive portion 16 is composed of a connecting sheet 18 and an adhesive attached to the connecting sheet 18, and the release paper 17 is adhered to the adhesive. Wherein the connecting piece 18 can be fastened to the pressing piece 5 in an intermittent manner. Intermittent connection is understood to mean that the connection between the connecting piece 18 and the pressing piece 5 is achieved by means of a number of small connection points, which are spaced apart. The connecting sheet 18 and the pressing piece 5 are fixed in an intermittent connection mode, so that the fixing effect of the bonding part 16 is ensured, and the disassembly is convenient.
The controller 14 is further provided with a control component, and the control component is used for switching connection between the anode and the cathode of the power supply 11 and the semiconductor refrigeration plate 15, and switching current flow direction, so that finally, functions of the cold end and the hot end of the semiconductor refrigeration plate 15 are exchanged, namely, original cold end generates heat, and the hot end is refrigerated. The control assembly comprises a first contact a21, a first contact b22, a first contact c23, a second contact a24, a second contact b25, a second contact c26, a control switch 27, a first switching member 28 and a second switching member 29, wherein the first switching member 28 is provided with a first contact part a31, a first contact part b32 and a first contact part c33, and the second switching member 29 is provided with a second contact part a34, a second contact part b35 and a second contact part c36. The first switching member 28 and the second switching member 29 are integrally connected by an insulating member, specifically an insulating plate 30. The control switch 27 comprises a rotating shaft 37, a translation push block 38, a limiting block 39, a control rod 40, a limiting ring 41 and an elastic piece 42, wherein a chute is formed in the controller 14, and the translation push block 38 is positioned in the chute to perform translation motion. One end of the control rod 40 is rotationally connected with the translation push block 38, the rotating shaft 37 is fixed in the middle of the control rod 40, the limiting ring 41 is fixed on the inner wall of the controller 14, one end of the rotating shaft 37 extends into the limiting ring 41, and the rotating shaft 37 can rotate relative to the limiting ring 41 and move along the length direction of the limiting ring 41 (the length direction of the limiting ring 41 is perpendicular to the extending direction of the sliding groove). The elastic member 42 is a V-shaped metal-like structure, and its bottom is fixed to the inner wall of the housing of the controller 14. The two sides can do similar rotation movement relative to the bottom by virtue of the deformation capability. The upper end of the elastic member 42 abuts against the insulating plate 30. The insulating plate 30 is provided with two guide rods 43, and the guide rods 43 are fixed with the shell of the controller 14. This configuration reduces the volume of the controller 14 by allowing the translational push block 38 to translate against the housing of the controller 14.
As shown in the figure, the first contact a21 and the first contact b22 are two contacts which are connected with one end of the semiconductor refrigeration plate 15 and are separated by wires, and the second contact a24 and the second contact b25 are two contacts which are connected with the other end of the semiconductor refrigeration plate 15 and are separated by wires. The first contact c23 is a contact on a wire connected to one of the electrodes of the power supply 11, and the second contact c26 is a contact on a wire connected to the other electrode of the power supply 11.
In the first state, as shown in fig. 4, the first contact portion a31 is always in contact with the first contact c23, the first contact portion b32 is always in contact with the first contact b22, the second contact portion a34 is always in contact with the second contact c26, and the second contact portion b35 is always in contact with the second contact b 25. With the cold end down and the hot end up, i.e. the cold end closer to the skin. The control lever 40 and the insulating plate 30 can be understood as being in contact with no stress or with some small play.
The translation push block 38 is pushed, at this time, the rotating shaft 37 moves down and rotates horizontally, when the rotating shaft 37 rotates to the control rod 40 vertical to the insulating plate 30, the rotating shaft 37 is located at the lowest end position, in order to keep stable contact, the translation push block 38 continues to move, the rotating shaft 37 moves up a small distance until the control rod 40 abuts against the limiting block 39, and at this time, the control rod 40 inclines to the other side. Since this inclination is steeper, the pivot 37 is still moved downwards relative to the first state, and the contact point of the lever 40 with the insulating plate 30 is also moved downwards.
In fig. 5, the first contact portion a31 is always in contact with the first contact c23, the second contact portion a34 is always in contact with the second contact c26, the first contact portion c33 is in contact with the second contact a24, the second contact portion c36 is in contact with the first contact a21, and the hot end is in the second state. The disconnection of the contacts is not illustrated.

The embodiment of the application relates to a radial artery compression hemostasis device, which is implemented by tearing off release paper 17 before use, and flattening and sticking a protective paste 19 on an adhesive part 16. After the power supply 11 is put in, the controller 14 automatically heats the pressing piece 5 to the set temperature after the semiconductor refrigeration plate 15 is electrified according to the set temperature, and the actual temperature can fluctuate up and down in the set temperature range slightly due to design reasons. The screw 6 is then manually turned to engage the puncture. The comfort level may ask the patient. A pressure sensor can be added on the pressing piece 5 to better control the pressure. But in practice the feeling of compression is different for each patient, so asking for patient comfort is a more preferred way.
