Description

Technical Field

[0001] The invention relates to the technical field of hemostasis equipment, and in particular to a convenient hemostasis device for nursing. Background Art

[0002] Nursing hemostatic devices include tourniquets, hemostatic pads, hemostatic clips, hemostatic powders, compression hemostats, etc. When the puncture device is removed from the patient's arm after a puncture operation, a compression hemostat is often used to press the artery of the puncture device to coagulate the blood in the patient's artery, thereby solving the problem of arterial bleeding in the patient.

[0003] However, during the use of a traditional compression hemostat, it is first fixed to a fixed position on the patient's arm with a strap, and then a squeezing force is applied to the patient's arm by turning the knob. After the wound at the artery in the patient's arm has coagulated, the strap can be directly loosened. During this operation, the patient often forgets to reset the knob, resulting in the device being fixed on the next patient's arm with the strap. Turning the knob fails to increase the squeezing force, so the medical staff needs to loosen the strap to reset the knob and then perform the above operation again, which makes the use of the device more cumbersome. At the same time, the repeated tightening and loosening of the strap can easily cause arterial bleeding at the puncture device on the patient's arm, which creates an unnecessary burden on the hemostasis operation.

DETAILED DESCRIPTION

[0042] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0043] During the use of traditional compression hemostat, the knob in the compression hemostat is often forgotten to be turned in the opposite direction to reset. When the compression hemostat is used again subsequently, after the compression hemostat is fixed to the specified position on the patient's arm by the strap, it is found that the knob has not been reset, and the strap needs to be loosened back and forth to re-fix it. The above operation makes the operation process of the compression hemostat more cumbersome. At the same time, the repeated tightening and loosening of the strap can easily cause arterial bleeding at the puncture device on the patient's arm, which creates an unnecessary burden on the hemostasis operation.

[0044] Embodiment 1: A convenient hemostatic device for nursing, such as Figure 1-Figure 3 As shown, it includes: a bracket 1; a first Velcro 2, installed on the bracket 1; an extrusion piece 3, slidably arranged on the bracket 1; a rotating sleeve 4, rotatably arranged on the extrusion piece 3, and slidably connected to the bracket 1, and an external thread is arranged on the side of the rotating sleeve 4 away from the extrusion piece 3; a rotating shaft 5, slidably arranged on the rotating sleeve 4, and is limitedly rotatably connected to the bracket 1, and a turntable is arranged at one end of the rotating shaft 5 located outside the bracket 1, and a spring is installed between the rotating shaft 5 and the rotating sleeve 4; two symmetrically distributed sliding blocks 6, both of which are slidably arranged in the bracket 1, and the opposite sides of the two sliding blocks 6 are both provided with internal threads, and the two sliding blocks 6 are contacted and matched to form continuous internal threads with the internal threads on the two sliding blocks 6, and the internal threads of the two sliding blocks 6 are both matched with the external threads on the rotating sleeve 4; a trigger mechanism is arranged on the bracket 1, and is used to control the relative positions of the two sliding blocks 6, so that the two sliding blocks 6 and the rotating sleeve 4 automatically switch between the matched state and the separated state, so that the extrusion piece 3 can apply a stable extrusion force to the patient's arm during subsequent use.

[0045] In the above scheme, the extrusion member 3 is set to a transparent material, which is convenient for the operator to observe whether the compressed part is bleeding through the extrusion member 3, and is convenient for the operator to accurately grasp the recovery status of the wound on the patient's arm. After the opposite sides of the two sliding blocks 6 contact, the internal threads on the two sliding blocks 6 cooperate to form a complete continuous internal thread, and the internal thread cooperates with the external thread on the rotating sleeve 4, so that the extrusion member 3 applies an extrusion force to the patient's arm by rotating the rotating shaft 5. The spring between the rotating shaft 5 and the rotating sleeve 4 is used for the automatic reset of the extrusion member 3 after the sliding block 6 is released from the cooperation with the rotating shaft 5, which simplifies the operation process of compression and hemostasis next time, and a one-way bearing can be connected between the rotating shaft 5 and the bracket 1. The one-way bearing allows the rotating shaft 5 to rotate only in one direction to prevent the extrusion member 3 from loosening after the patient's arm is pressed tightly, and the rotating disk of the rotating shaft 5 can be sprayed with a rotation mark when it is tightened (not shown in the attached figure), which is convenient for the user to use the device correctly. In the initial state, the spring between the rotating shaft 5 and the rotating sleeve 4 is in a compressed state.

[0046] like Figure 3 and Figure 4 As shown, an elastic block 301 is installed at one end of the extrusion member 3 away from the bracket 1, and a side of the elastic block 301 away from the extrusion member 3 is set as an arc surface; the arc surfaces of the extrusion member 3 and the elastic block 301 are both provided with grooves.

[0047] In the above scheme, the elastic block 301 is set to be made of rubber material so that it can be deformed. Combined with the curved surface of the elastic block 301, the elastic block 301 can distribute the extrusion force more evenly on the arm under the combined effect of the softness and elasticity of the rubber material, thereby reducing local high-pressure points. At the same time, the softness and elasticity of the rubber material make it more comfortable when pressure is applied, reducing the patient's discomfort.

[0048] like Figure 2 and Figure 5 As shown, the trigger mechanism includes: two symmetrically distributed fixed frames 7, both fixedly connected to one side of the bracket 1 close to the extrusion member 3, and respectively located on both sides of the extrusion member 3, and the fixed frame 7 is provided with a guide groove; two symmetrically distributed first sliding frames 8, respectively slidably set in the guide grooves of adjacent fixed frames 7, the guide groove on the fixed frame 7 is composed of an inclined section and a vertical section, the first sliding frame 8 is provided with a wave pad for increasing the friction between it and the patient's arm, and the vertical section of the guide groove on the fixed frame 7 is used to limit the lateral movement of the first sliding frame 8 located therein; two symmetrically distributed sliding plates 9, respectively slidably set in adjacent first sliding frames 8, and a spring is installed between the first sliding frame 8 and the adjacent sliding plate 9; two symmetrically distributed connecting frames 10, respectively fixedly connected to the adjacent sliding plates 9, and respectively fixedly connected to the adjacent sliding blocks 6.

[0049] In the above scheme, as the device uses two first sliding frames 8 to contact the patient's arm first, the wave pad on the first sliding frame 8 increases the friction between the first sliding frame 8 and the contact point on the patient's arm. Subsequently, with the tightening of the first Velcro 2, the two first sliding frames 8 are squeezed by the arm and move along the guide grooves on the adjacent fixed frames 7. The movement of the two first sliding frames 8 simultaneously drives the contact points on the arm to move together, thereby realizing the concentrated squeezing of the skin at the wound on the patient's arm, reducing the pulling force on the arterial puncture during the squeezing process, and accelerating the healing of the arterial puncture. At the same time, after the tightening of the first Velcro 2, during the rotation of the shaft 5, the two sliding blocks 6 Due to the guiding effect of the internal thread groove, the rotating sleeve 4 moves downward, and at the same time, the two sliding blocks 6 are subjected to an upward extrusion force. Since the two first sliding frames 8 move to the vertical ends of the guide grooves on the fixed frame 7, the two first sliding frames 8 cannot move away from each other. The two first sliding frames 8 prevent the two sliding blocks 6 from moving away from each other through two connecting frames 10, ensuring that the internal threads of the two sliding blocks 6 are always matched with the external threads of the rotating sleeve 4, ensuring that the rotating sleeve 4 drives the extrusion piece 3 to move downward stably and apply a stable extrusion force to the artery of the patient's arm. In the initial state, the spring between the first sliding frame 8 and the adjacent sliding plate 9 is in a compressed state, and the inclined sections of the guide grooves of the two fixed frames 7 gradually move away from each other from top to bottom.

[0050] Working principle: When performing a hemostasis operation on the artery pierced by the puncture device on the patient's arm, the medical staff places the bracket 1 above the puncture site, and makes the extrusion piece 3 and the elastic block 301 squeeze the puncture site. At the same time, the puncture needle of the puncture device is located in the groove of the extrusion piece 3 and the elastic block 301. Then the medical staff tightens the first Velcro 2 to make the bracket 1 and the first Velcro 2 close to the patient's arm.

[0051] During the process of tightening the first Velcro 2, the patient's arm squeezes the first sliding frame 8 and retracts it into the adjacent fixed frame 7. At this time, due to the guiding effect of the guide groove on the adjacent fixed frame 7 on the first sliding frame 8, the first sliding frame 8 drives the adjacent sliding plate 9 to move together. During this process, the sliding plate 9 is always in contact with the bracket 1. At this time, the spring between the sliding plate 9 and the adjacent first sliding frame 8 is compressed, and the sliding plate 9 moves through the adjacent connecting frame 10 to drive the adjacent sliding block 6 to move together, so that the internal thread of the sliding block 6 cooperates with the external thread of the rotating sleeve 4.

[0052] After the first Velcro 2 is tightened, the medical staff rotates the turntable of the rotating shaft 5, and the rotating shaft 5 drives the rotating sleeve 4 to rotate together. During the rotation process, the rotating sleeve 4 is squeezed by the internal threads on the two sliding blocks 6, and the rotating sleeve 4 drives the extrusion piece 3 and the elastic block 301 to move downward together. The movement of the rotating sleeve 4 compresses the connected spring at the same time, and the extrusion piece 3 and the elastic block 301 move downward to apply further squeezing force to the puncture site on the patient's arm. Subsequently, a label of the start time of squeezing is attached to the bracket 1 (this time is convenient for the operator to remove the device after the specified squeezing time, and the time record can also be recorded by setting an electronic timer on the bracket 1).

[0053] After squeezing for a specified time, the operator first loosens the first Velcro 2 and removes the device. After the device is removed, the first sliding frame 8 moves in the opposite direction and resets due to the elastic force of the spring between the first sliding frame 8 and the adjacent sliding plate 9. At the same time, the two sliding blocks 6 move in the opposite direction and reset. The two sliding blocks 6 are reset to release the cooperation with the sliding blocks 6. At this time, under the action of the elastic force of the spring connected to the rotating sleeve 4, the rotating sleeve 4 drives the extruding member 3 to move in the opposite direction and reset, which is convenient for the direct use of the device next time and simplifies the use and operation of the device.

[0054] Embodiment 2: Based on embodiment 1, Figure 2 and Figure 6 As shown, it also includes: a second sliding frame 11, which is slidably set on the bracket 1, and a spring is installed between the bracket 1, the second sliding frame 11 is provided with evenly distributed inclined teeth, and the inclined teeth of the second sliding frame 11 are limitedly matched with the first Velcro 2; the first Velcro 2 is set to be a woven material, so that the inclined teeth of the second sliding frame 11 are convenient for inserting into the first Velcro 2.

[0055] In the above scheme, in the initial state, the spring connected to the second sliding frame 11 is in a compressed state, and the teeth on the second sliding frame 11 are inclined upward from right to left (with the second sliding frame 11 being attached to the spring). Figure 6 As shown), the inclined direction makes it possible for the teeth of the second sliding frame 11 to not restrict the movement of the first Velcro 2 during the tightening process of the first Velcro 2. However, after the first Velcro 2 is tightened, the teeth of the second sliding frame 11 are inserted into the first Velcro 2 under the elastic force of the spring connected to the second sliding frame 11, so as to restrict the movement of the first Velcro 2, thereby avoiding loosening of the device during use and improving the working stability of the device. When loosening the first Velcro 2 subsequently, the medical staff first moves the second sliding frame 11 to retract the teeth of the second sliding frame 11 into the bracket 1, and then loosens the first Velcro 2.

[0056] Embodiment 3: Based on embodiment 2, Figure 1 , Figure 7 and Figure 8As shown, it also includes: a cylindrical rod 12, which is detachably mounted on the bracket 1; a sliding sleeve 13, which is slidably arranged on the cylindrical rod 12 in a limited manner; a fixing frame 14, which is slidably arranged on the side of the sliding sleeve 13 away from the bracket 1; a second Velcro 15, which is installed on the fixing frame 14; and a knob 16, which is threadedly arranged on the sliding sleeve 13 and is squeezed and matched with the cylindrical rod 12.

[0057] In the above scheme, a vertical groove is provided on the knob 16, which is convenient for medical staff to turn the knob 16 with a flat-head screwdriver. At the same time, during the use of the device, the side on which the cylindrical rod 12 is installed needs to face the patient's hand. When the device is used for patients whose hands can move, the operator installs the cylindrical rod 12 on the bracket 1, and releases the squeezing of the cylindrical rod 12 by turning the knob 16, and then adjusts the position of the sliding sleeve 13 to fix the fixing frame 14 and the second Velcro 15 on the patient's wrist, and then rotates the knob 16 in the opposite direction to make the knob 16 squeeze and fit with the cylindrical rod 12 again to complete the fixation of the cylindrical rod 12 and the sliding sleeve 13. At this time, under the support of the cylindrical rod 12 and the sliding sleeve 13, the squeezing parts of the extrusion piece 3 and the elastic block 301 are prevented from being dislocated during the activity of the patient's arm, thereby maintaining the hemostatic function of the device. If the support is not needed, the cylindrical rod 12 can be removed.

[0058] Figure 7 and Figure 8 As shown, the cylindrical rod 12, the bracket 1 and the extrusion member 3 are provided with air guide holes connected in sequence, the elastic block 301 is provided with a chamber, the chamber of the elastic block 301 is connected with the air guide hole of the extrusion member 3, a spring is installed between the sliding sleeve 13 and the fixed frame 14, and the sliding sleeve 13 and the fixed frame 14 are both provided with a one-way valve.

[0059] In the above scheme, in the initial state, the spring between the sliding sleeve 13 and the fixing frame 14 is in a compressed state. When the above components are used for support, if the patient frequently moves his wrist, the movement of the patient's wrist causes the fixing frame 14 and the second Velcro 15 to move to the right (the direction is as shown in FIG. Figure 7 For example, the fixing frame 14 moves to compress the gas between it and the sliding sleeve 13, and then the gas enters the sliding sleeve 13 through the one-way valve on the sliding sleeve 13 to increase the internal pressure, and then the gas acts on the elastic block 301 through the air guide holes on the cylindrical rod 12, the air guide holes on the bracket 1 and the air guide holes on the extrusion member 3. The gas pressure in the elastic block 301 increases, thereby enhancing the squeezing force of the elastic block 301 on the patient's arm, further strengthening the squeezing of the puncture site, and improving the hemostatic effect of the device.

Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
