Description

Technical Field

[0001] The utility model relates to the field of post-PICC hemostasis, in particular to a compression clamp and a puncture point compression hemostat. Background Art

[0002] After the PICC catheter puncture in the upper arm, it is generally necessary to stop bleeding at the patient's puncture point. The traditional way to stop bleeding is for the patient to use the hand on the non-punctured side to press directly on the gauze covering the puncture point to stop bleeding. This process usually takes about 20 minutes to effectively stop bleeding, and those with coagulation dysfunction need to extend the pressure time depending on the situation. Due to the long pressing time, the patient may shift the pressing position due to fatigue, hand tremors, improper pressing, etc., and fail to press correctly on the puncture point, causing secondary bleeding at the puncture point, and failing to achieve the ideal hemostatic effect. In addition, during the pressing period, the patient needs to continue pressing on the puncture point with the hand on the non-punctured side, which makes the patient unable to drink water or go to the toilet on his own, which brings a certain degree of inconvenience to the patient.

[0003] To this end, the prior art provides a PICC puncture point hemostatic clamp that can be clamped on the patient's arm and correctly press the puncture point to stop bleeding, replacing the patient's manual pressing to stop bleeding. However, the two clamp arms of the hemostatic clamp are hinged by a torsion spring, and the two clamp arms are an integrated structure, resulting in the hemostatic clamp being unable to adjust the tightness of the hemostatic clamp according to the arm circumference of different patients, and the pressing force on the puncture point, and the scope of application is small.

The clamping space gradually increases, and the arm circumference range that can be placed in the clamping space is expanded. Therefore, the compression clamp can be suitable for arms with different arm circumferences, which improves the application range of the compression clamp. As the clamping space gradually increases, the clamping of the compression clamp on the arm with the same arm circumference gradually becomes loose; at the same time, as the length of the clamping end of the first clamping arm increases, the opening angle required when the two clamping ends clamp the arm with the same arm circumference can be gradually reduced. Since the force of the first elastic member is proportional to the angle between the two clamping ends, the pressure on the arm gradually decreases. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] The utility model provides a compression clamp 1, which is used to solve the problem of how to adjust the tightness of the patient's arm and the pressing force on the puncture point.

[0045] See also Figure 1 and Figure 2 As shown, Figure 1 This is a three-dimensional diagram of the compression clamp and the puncture point compression hemostat in the embodiment when the first clamp arm is in the longest position. Figure 2 This is a stereoscopic view of the compression clamp and the puncture point compression hemostat in the embodiment when the first clamp arm is at the shortest position. The compression clamp 1 includes a first clamp arm 11 , a second clamp arm 12 and a first elastic member 13 .

[0046] The first clamp arm 11 and the second clamp arm 12 are rotatably connected, and each includes a clamping end 15 on the same side of the rotatable connection, and a clamping space 14 for placing an arm is formed between the clamping ends 15 of the first clamp arm 11 and the second clamp arm 12. The clamping end 15 of the first clamp arm 11 includes a fixed portion 111 and a movable portion 112, and the fixed portion 111 and the movable portion 112 are slidably connected in the length direction of the clamping end 15. The connection between the fixed portion 111 and the movable portion 112 has a fixing structure 4, and the fixing structure 4 is used to fix the relative position of the movable portion 112 and the fixed portion 111. In this way, the fixed portion 111 and the movable portion 112 slide relatively along the length direction of the clamping end 15, and the length of the clamping end 15 of the first clamp arm 11 can be telescopically adjusted.

[0047] The first elastic member 13 is installed between the first clamping arm 11 and the second clamping arm 12. When the arm is placed in the clamping space 14, the first elastic member 13 has a force to drive the clamping ends 15 of the first clamping arm 11 and the second clamping arm 12 to approach each other to clamp the arm, and the magnitude of the force is proportional to the angle between the two clamping ends 15. In this way, the larger the angle between the two clamping ends 15, the greater the force between the two clamping ends 15, that is, the greater the pressure on the arm in the clamping space 14.

[0048] When the patient uses the compression clamp 1 of the above technical solution, the patient clamps the arm between the clamping end 15 of the first clamp arm 11 and the second clamp arm 12, and the first elastic member 13 provides a pressing force on the arm in the clamping space 14 to achieve the hemostasis function. During the use, the compression clamp 1 can adjust the tightness and pressing force on the patient's arm to improve the comfort of the compression clamp 1. The specific principle is as follows:

[0049] When in use, the movable part 112 can be controlled to slide relative to the fixed part 111 to adjust the length of the clamping end 15 of the first clamping arm 11. As the length of the clamping end 15 of the first clamping arm 11 increases, the clamping space 14 between the two clamping ends 15 gradually increases, and the arm circumference range that can be placed in the clamping space 14 is expanded. Therefore, the compression clamp 1 can be suitable for arms of different arm circumferences, which improves the applicable range of the compression clamp 1. As the clamping space 14 gradually increases, the clamping of the compression clamp 1 on the arm of the same arm circumference gradually becomes loose; at the same time, as the length of the clamping end 15 of the first clamping arm 11 increases, the opening angle required for the two clamping ends 15 to clamp the arm of the same arm circumference can be gradually reduced. Since the force of the first elastic member 13 is proportional to the angle between the two clamping ends 15, the pressing force on the arm gradually decreases.

[0050] The clamping ends 15 of the first clamping arm 11 and the second clamping arm 12 may be designed to be symmetrical arc-shaped structures, which is more ergonomic and further improves the comfort of the compression clamp 1 .

[0051] The first elastic member 13 may be a torsion spring, which is sleeved on the rotating shafts of the first clamp arm 11 and the second clamp arm 12, and the two protruding ends of the torsion spring respectively abut against the first clamp arm 11 and the second clamp arm 12 to drive the clamping ends 15 of the first clamp arm 11 and the second clamp arm 12 to approach each other.

[0052] See also Figure 1 , Figure 3 and Figure 4 As shown, Figure 3 is a cross-sectional view of the embodiment in which the fixed part and the movable part are in a locked state, Figure 4 It is a cross-sectional view of the fixed part and the movable part in the unlocked state in the embodiment. In one embodiment of the first clamping arm 11 and the fixed structure 4, the movable part 112 has a slide groove 113 extending along the length direction of the clamping end 15, and the fixed part 111 is slidably connected to the inner side of the slide groove 113. One side of the fixed part 111 is provided with at least two limit grooves 41, and each limit groove 41 is evenly spaced along the length direction of the clamping end 15. The fixed structure 4 includes a limit member 42, a second elastic member 43 and a pressing member 44. The limit member 42 is located in the slide groove 113 and is opposite to and plugged into any limit groove 41. One end of the second elastic member 43 is installed in the slide groove 113 of the movable part 112 by welding or bonding, and the other end is connected to the limit member 42 by welding or bonding. The second elastic member 43 has an elastic force that drives the limit member 42 to move toward the limit groove 41. The pressing member 44 is located on the movable portion 112 and is configured to drive the limiting member 42 to overcome the elastic force of the second elastic member 43 and move away from the limiting groove 41. In this way, when the pressing member 44 is pressed, the pressing member 44 can drive the limiting member 42 to overcome the elastic force of the second elastic member 43 and move away from the limiting groove 41, unlocking the fixing structure 4 of the movable portion 112 and the fixed portion 111, so that the movable portion 112 can slide freely relative to the fixed portion 111, so as to flexibly adjust the length of the first clamping arm 11. On the contrary, when the pressing member 44 is released, if the limiting member 42 is opposite to any limiting groove 41 on the fixed portion 111, the limiting member 42 will be inserted into the limiting groove 41 under the elastic force of the second elastic member 43, fixing the fixed portion 111 and the movable portion 112, thereby fixing the length of the clamping end 15 of the first clamping arm 11.

[0053] The second elastic member 43 may be a compression spring or a tension spring.

[0054] In addition to the above-mentioned implementations, the fixing structure 4 may also use a limiting structure such as a damping structure to fix the relative position of the movable part 112 and the fixing part 111 .

[0055] See also Figure 3 and Figure 4As shown, on the basis of the above embodiment, the pressing member 44 is slidably connected to the movable part 112, and the pressing member 44 includes a pressure surface 441 and a guide surface 442. The pressure surface 441 is located outside the movable part 112, and the guide surface 442 is located in the slide groove 113 and extends obliquely toward the limiting member 42 and the fixed part 111. The limiting member 42 includes a mating surface 421, and the mating surface 421 is parallel to the pressure surface 441. When the pressure surface 441 is compressed, the pressing member 44 slides relative to the movable part 112, and the guide surface 442 is in surface contact with the pressure surface 441, and the linkage limiting member 42 overcomes the elastic force of the second elastic member 43 and moves back to the limiting groove 41. In this way, when the pressure surface 441 is subjected to external pressing force, the pressing member 44 can be driven to slide on the movable part 112, and the inclined guide surface 442 is in contact with the pressure surface 441, so that the sliding of the pressing member 44 toward the movable part 112 can be converted into the movement of the limiting member 42 away from the fixed part 111, and the limiting member 42 can be quickly moved out of the limiting groove 41, which is convenient and quick to operate.

[0056] See also Figure 1 and Figure 2 As shown, the utility model also provides a puncture point compression hemostat, which includes a hemostat 2, a timing device 3 and the above-mentioned compression clamp 1. Among them, the hemostat 2 is installed on the movable part 112, and the hemostat 2 is located in the clamping space 14; the timing device 3 is installed on the compression clamp 1 by screwing or welding, etc., and is used to measure the compression time of the compression clamp 1 on the patient's arm; and the specific implementation process of the compression clamp 1 can refer to the above description, and this embodiment will not be repeated here. Since the compression clamp 1 has the above-mentioned technical effects, the puncture point compression hemostat with the compression clamp 1 also has corresponding technical effects.

[0057] When the puncture point compression hemostat of the above technical solution is used, the compression clamp 1 is clamped on the patient's arm, and the compression clamp 1 provides a pressing force to press the hemostatic piece 2 on the patient's puncture point to stop bleeding at the puncture point. At the same time, the timing device 3 is started to start measuring the pressing time. When the pressing time measured by the timer 31 reaches the predetermined pressing time, the hemostatic treatment of the puncture point is completed, and an effective hemostatic effect is achieved. At this time, the compression clamp 1 can be removed from the patient's upper arm. Among them, the hemostatic piece 2 can slide to different positions relative to the fixed part 111 with the movable part 112, so that different pressing forces can be applied to the puncture point; and the timing device 3 can solve the problem that the patient easily forgets the pressing time, causing the puncture needle eye to be in a compressed state for a long time or the pressing time is insufficient.

[0058] See also Figure 1 and Figure 2As shown, in one embodiment of the hemostatic device 2, the hemostatic device 2 includes a disposable hemostatic sheet 21, an elastic band 22 and a connecting sheet 23. The elastic band 22 is sleeved on the movable portion 112. One side of the connecting sheet 23 is fixed to the elastic band 22 by sewing or bonding, and the connecting sheet 23 is located in the clamping space 14. The other side of the connecting sheet 23 is detachably connected to the disposable hemostatic sheet 21 by a hook surface or a self-adhesive surface of a Velcro. The disposable hemostatic sheet 21 can use a disposable cotton sheet or gauze block or other medical hemostatic items. In this way, the position of the connecting piece 23 on the clamping end 15 can be steplessly adjusted through the elastic band 22, so that the hemostatic position of the disposable hemostatic piece 21 can be steplessly adjusted to ensure that the disposable hemostatic piece 21 can be aligned with the position of the puncture point for hemostasis, and the disposable hemostatic piece 21 is detachably connected through the connecting piece 23, so that the disposable hemostatic piece 21 can be replaced quickly and conveniently, so that the hemostatic piece 2 can be reused. In this way, each time the puncture point compression hemostat is used for hemostasis treatment, only the disposable hemostatic piece 21 needs to be replaced, which effectively reduces waste.

[0059] See also Figure 5 As shown, Figure 5 : is a block diagram of the connection structure of the timing device, the pressure sensor and the controller in the embodiment. The puncture point compression hemostat also includes a pressure sensor 5, which is installed on the hemostatic member 2 by pasting or other means, and is used to sense the pressing force of the compression clip 1 on the puncture point. In this way, the puncture point compression hemostat can sense the actual pressing force of the puncture point on the arm through the pressure sensor 5, instead of the patient's own feeling, and can obtain a more accurate pressing force value, so that medical personnel can accurately adjust the pressing force on the puncture point of different patients.

[0060] The pressure sensor 5 can be installed between the elastic band 22 and the connecting piece 23, or on the side of the elastic band 22 close to the movable part 112, but the pressure sensor 5 must be located between the disposable hemostatic sheet 21 and the movable part 112 to ensure that the pressure sensor 5 can accurately sense the actual pressure value of the arm puncture point.

[0061] See also Figure 5As shown, the puncture point compression hemostat also includes a controller 6, which is installed on the compression clamp 1 and is electrically connected to the pressure sensor 5 and the timing device 3. When the controller 6 receives the pressure value sent by the pressure sensor 5, the controller 6 starts the timing device 3 to start timing. When the pressure value sent by the pressure sensor 5 received by the controller 6 is zero or the controller 6 cannot receive the pressure value sent by the pressure sensor 5, the controller 6 controls the timing device 3 to reset or turn off the timing. It can be seen that the puncture point compression hemostat can start timing at the first time the compression clamp 1 is clamped on the patient's arm through the cooperation of the controller 6, the pressure sensor 5 and the timing device 3, and plays the role of automatic timing, effectively avoiding the situation where medical staff or patients forget to time, and can reset the timing at the first time the compression clamp 1 is removed for the next use.

[0062] The above-mentioned pressure sensor 5 and controller 6 can both use existing pressure sensors 5 and controllers 6, and the controller 6 can be installed inside the timing device 3 by screwing or welding, and then installed on the compression clamp 1. The controller 6 can also be directly installed on the compression clamp 1 by screwing or welding.

[0063] See also Figure 5 As shown, in one embodiment of the timing device 3, the timing device 3 includes a timer 31 and a prompter 32, and both the timer 31 and the prompter 32 are electrically connected to the controller 6. The controller 6 reads the measured time of the timer 31 and controls the opening and closing of the prompter 32. In this way, when the pressing time measured by the timer 31 reaches the predetermined pressing time, the controller 6 starts the prompter 32, which can prompt medical staff, patients, patients' family members and other relevant personnel to remove the puncture point compression hemostat in time, and when the puncture point compression hemostat is removed, the controller 6 turns off the prompter 32.

[0064] The timer 31 can use an existing digital timer 31, so that medical staff, patients, their family members and other relevant personnel can intuitively read the actual compression time. The prompter 32 can use a buzzer prompter 32, a voice prompter 32, or a device with a prompt function such as a prompt light, so as to conveniently prompt relevant personnel to remove the hemostat, and the prompter 32 can also be connected to the existing medical system signal, so as to conveniently remotely prompt medical staff to remove the hemostat.
