A hemostatic device with thrombin coated on the surface

Abstract

The present invention relates to the field of medical devices. The present invention discloses a hemostat with thrombin coated on the surface. The problem to be solved by the present invention is that when the existing hemostat performs a hemostatic operation on the puncture site on the patient's thigh, the medical staff needs to press the hemostat when pulling out the puncture catheter, so that the hemostat is pressed on the puncture catheter, thereby avoiding bleeding from the patient's leg when the puncture catheter is pulled out. This operation requires cooperation between two medical staff, and after the puncture catheter is pulled out, it is necessary to continue to apply pressure to the patient's leg. The pressure value manually applied by the medical staff is not easy to control, and it is easy to cause deviation when the puncture catheter is pulled out. The present invention allows the operator to first adjust the setting position of the adjustment slider on the fixed sleeve, and set the initial pressure value by adjusting the slider, so that when the operator pulls out the puncture catheter, appropriate pressure is provided to avoid bleeding from the patient's leg when the catheter is pulled out.

[0002] With the improvement of living conditions and changes in working methods, the incidence of coronary heart disease has been increasing year by year. Percutaneous transluminal coronary angioplasty is the main method for treating coronary heart disease. At present, radial artery puncture is often used in clinical practice to intervene in the treatment of coronary heart disease. After radial artery puncture, it is necessary to stop bleeding at the puncture site to avoid bleeding at the puncture site affecting the treatment. When stopping bleeding, a compression hemostat is often used to stop bleeding at the puncture site.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, when the protrusion on the spring card corresponds to the card interface on the adjusting slider, the pressing rod and the pressing cylinder will be restricted in the fixed cylinder under the restriction of the spring card, so that the pressing cylinder maintains the pressure on the containing tube, and then the medical staff can pull out the puncture catheter inserted into the patient's thigh, without the need for the medical staff to press the part of the patient's puncture catheter by hand when pulling out the puncture catheter, so as to avoid blood from the patient's thigh from overflowing when the puncture catheter is pulled out. Through this setting, when the medical staff pulls out the patient's puncture guide rail, there is no need to press the patient's thigh.

[0014] In the present invention, the rotation of the rotating cylinder drives the movable sleeve to move on the fixed cylinder toward the direction of the containing tube, and the movable sleeve will drive the locking plate to move the adjusting slider at this time. When the adjusting slider moves downward, the spring card is clamped in the card interface, and can synchronously drive the spring card to move downward. The spring card will continue to squeeze the pressing cylinder under the action of the initial force of the pressing rod, so that the pressing cylinder drives the containing tube to apply a greater force toward the patient's leg, thereby tightly pressing the containing tube and the puncture site on the patient's leg to avoid bleeding at the puncture site on the patient's leg. Through this arrangement, the medical staff can first perform preliminary pressure hemostasis when pulling out the puncture catheter, and then adjust the rotating cylinder by the medical staff so that the adjusting slider can apply greater pressure on the patient's leg when continuing to move, thereby effectively stopping bleeding at the patient's puncture site.

[0015] In the present invention, when the carrying disk rotates, the regulating disk will be rotated through the limit block, and the rotation of the regulating disk will cause the switch knob to rotate. When the switch knob rotates, the thrombin solution stored in the connecting sleeve will flow into the gelatin sponge, so that the gelatin sponge is quickly contaminated with the thrombin solution. When the patient pulls out the puncture catheter, the gelatin sponge can quickly contact with the thrombin solution to stop bleeding from the patient's legs, thereby improving the efficiency of stopping bleeding from the patient's legs.

[0031] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, a through groove is provided on the outer wall of the fixed cylinder 21, and the pressure regulating member 3 includes an adjusting slider 31 slidably arranged in the through groove, and a card interface 311 is provided on the adjusting slider 31, and plug plates 312 are fixedly connected to both ends of the adjusting slider 31, respectively, and the plug plates 312 are slidably matched with the outer wall of the fixed cylinder 21, and a scale mark 313 is provided on the outer wall of the fixed cylinder 21 beside the adjusting slider 31;

[0032] The pressure regulating member 3 further comprises a pressing cylinder 32 slidably arranged on the inner wall of the fixed cylinder 21, a pressure spring 33 is connected between the pressing cylinder 32 and the inner wall of the fixed cylinder 21, a clamping cavity 321 is provided on the pressing cylinder 32, a spring card 34 is inlaid on the inner wall of the clamping cavity 321 of the pressing cylinder 32, a pressing rod 35 is slidably arranged in the pressing cylinder 32, a return spring 36 is connected between the pressing rod 35 and the spring card 34, and the containing tube 5 is clamped and matched with the outer wall of the pressing cylinder 32;

[0033] The spring card 34 is also fixedly connected with a protrusion 341, and the protrusion 341 is engaged with the card interface 311 on the adjusting slider 31. The spring card 34 is also provided with a rectangular groove 342. The pressing rod 35 is provided with a slope 343 in a wedge shape at one end facing the spring card 34. The slope 343 on the pressing rod 35 contacts the rectangular groove 342 on the spring card 34.

[0034] When the medical staff performs compression hemostasis on the patient, the comfort belt 14 is placed under the patient's thigh, and then the pressure regulator 2 is fixed to the patient's thigh through the Velcro 13 and the fixing belt 12, and the pressure regulator 2 is above the puncture site. Then the medical staff moves the adjusting slider 31 on the outer wall of the fixing tube 21 for a distance according to the depth of the puncture catheter inserted into the patient's thigh and the patient's actual physical condition, so that the adjusting slider 31 moves to the side of the corresponding scale 313. At this time, the medical staff moves the pressing rod 35, and the pressing rod 35 squeezes the return spring 36 to press the pressing tube 32 downward. The pressing tube 32 slides downward in the fixing tube 21 to squeeze the pressure spring 33, and the bottom of the pressing tube 32 drives the containing tube 5 to move downward, so that the containing tube 5 is pressed toward the puncture site of the patient, and one end of the spring card 34 with a protrusion 341 is close to the inner wall of the fixing tube 21 and moves. The spring card 34 moves until the protrusion 341 on the spring card 34 corresponds to the card interface 311 on the adjusting slider 31. Under the restriction of the spring card 34, the pressing rod 35 and the pressing cylinder 32 are restricted in the fixed cylinder 21, so that the pressing cylinder 32 maintains the pressure on the containing tube 5. Then the medical staff can pull out the puncture catheter inserted into the patient's thigh. There is no need for the medical staff to press the part of the patient's puncture catheter by hand when pulling out the puncture catheter, so as to prevent the blood from spilling out of the patient's thigh when the puncture catheter is pulled out. Through this setting, the medical staff does not need to press the patient's thigh when pulling out the patient's puncture guide. The medical staff first adjusts the setting position of the adjusting slider 31 on the fixed sleeve, and sets the initial pressure value by adjusting the slider 31, so that when the medical staff pulls out the puncture catheter, appropriate pressure is provided to avoid bleeding from the patient's leg when the catheter is pulled out.

[0035] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Fig.10 As shown, the adjusting device 4 includes a rotating cylinder 41 rotatably arranged on the outer wall of the fixed cylinder 21, the inner wall of the rotating cylinder 41 is spirally arranged, a movable sleeve 42 is slidably arranged on the outer wall of the fixed cylinder 21, the movable sleeve 42 is spirally matched with the rotating cylinder 41, a fixed snap ring 43 is sleeved on the outer wall of the fixed cylinder 21, the fixed snap ring 43 is fixedly connected to the adjusting slider 31, a locking plate 44 is fixedly arranged on the outer wall opposite to the fixed snap ring 43, limiting holes 441 are evenly spaced on the locking plate 44, the locking plate 44 extends toward the inside of the movable sleeve 42, and the locking plate 44 is slidably matched with the movable sleeve 42, and a positioning buckle 45 docking with the limiting hole 441 is arranged on the outer wall of the movable sleeve 42;

[0036] A pressurizing knob 46 is clamped on the top of the rotating cylinder 41, and a contact plate 47 is extended from one end of the pressurizing knob 46. A sliding groove 411 is provided on the outer wall of the rotating cylinder 41, and the contact plate 47 is slidably matched with the sliding groove 411, and the contact plate 47 contacts the end of the pressing rod 35;

[0037] When the medical staff makes the adjusting slider 31 slide on the outer wall of the fixed cylinder 21, the medical staff inserts the resistance plate 47 on the pressure knob 46 into the slide groove 411 in the rotating cylinder 41, and then drives the pressing rod 35 to press through the resistance plate 47. The movement of the adjusting slider 31 will drive the fixed clamping ring 43 to move, and the locking plate 44 on the fixed clamping ring 43 can move in the movable sleeve 42. When the adjusting slider 31 moves to the specified position, the positioning buckle 45 is connected with the limiting hole 441 on the locking plate 44 to achieve the positioning between the movable sleeve 42 and the fixed clamping ring 43. After the medical staff pulls out the puncture catheter from the patient's leg, the pressure knob 46 can be inserted into the end face of the rotating cylinder 41, and then the rotating cylinder 41 is rotated. The rotation of the rotating cylinder 41 drives the movable sleeve 42 on the fixed cylinder 21 toward When the holding tube 5 moves in the direction of rotation, the movable sleeve 42 will drive the locking plate 44 to move the adjusting slider 31. When the adjusting slider 31 moves downward, the spring card 34 is engaged in the card interface 311, and can synchronously drive the spring card 34 to move downward. The spring card 34 will continue to squeeze the pressing cylinder 32 under the action of the initial force of the pressing rod 35, so that the pressing cylinder 32 drives the holding tube 5 to apply a greater force toward the patient's leg, thereby tightly pressing the holding tube 5 and the puncture site on the patient's leg to prevent bleeding at the puncture site on the patient's leg. Through this setting, the medical staff can first perform preliminary pressure hemostasis when pulling out the puncture catheter, and then adjust the rotating cylinder 41 so that the adjusting slider 31 can apply greater pressure on the patient's leg when continuing to move, thereby effectively stopping bleeding at the patient's puncture site.

[0038] When the patient's hemostasis work is completed, when the medical staff stops the hemostasis operation on the patient, they only need to move the protrusion 341 in the card interface 311 in the adjusting slider 31 to separate the spring card 34 from the adjusting slider 31. Under the action of the pressure spring 33 and the return spring 36, the pressing rod 35 and the pressing cylinder 32 will be reset, thereby stopping the continued pressure. If the contact pressure between the protrusion 341 on the spring card 34 and the card interface 311 is too large, the pressing rod 35 can be moved toward the pressing cylinder 32 again. At this time, the pressing rod 35 is provided with a wedge-shaped inclined surface 343, which will contact the inner wall of the rectangular groove 342 on the spring card 34, and then the spring card 34 is moved downward under the drive of the inclined surface 343. After the spring card 34 moves downward, the protrusion 341 is separated from the card interface 311, thereby realizing the reset operation of the pressing rod 35 and the pressing cylinder 32.

[0039] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.10 , Fig.11 and Fig.12 As shown, the containing tube 5 comprises a connecting sleeve 51, a mounting rod 52 is relatively arranged at the bottom of the fixing cylinder 21, the connecting sleeve 51 is slidably arranged on the mounting rod 52, an adjusting disk 54 is rotatably arranged on the top of the connecting sleeve 51, a card slot is arranged on the adjusting disk 54, a bearing plate 55 is rotatably arranged on the bottom of the pressing cylinder 32, a corresponding arc slot 56 is opened on the outer wall of the bearing plate 55, a card rod 53 is extended toward the corresponding arc slot 56 on the two mounting rods 52, a limit block 57 engaged with the card slot is arranged on the bearing plate 55, a rotating switch knob 58 is arranged in the connecting sleeve 51, and the switch knob 58 is connected to the adjusting disk 54;

[0040] A gelatin sponge 59 is clamped at the bottom of the connecting sleeve 51, and the gelatin sponge 59 is located below the switch knob 58 in the connecting sleeve 51;

[0041] The gelatin sponge 59 corresponds to the puncture site of the patient's leg, and a thrombin solution is placed in the connecting sleeve 51. When the pressing cylinder 32 is pressed toward the patient's leg, the pressing cylinder 32 moves downward to move the carrying plate 55 downward, and the carrying plate 55 drives the adjusting plate 54 that is clamped to move downward. When the carrying plate 55 moves downward, the arc groove 56 provided on the outer wall of the carrying plate 55 contacts the clamping rod 53 on the mounting rod 52, and then drives the carrying plate 55 to rotate under the restriction of the clamping rod 53. When the supporting disk 55 rotates, the regulating disk 54 will be rotated through the limit block 57, and the regulating disk 54 will rotate, and the switch knob 58 will rotate. When the switch knob 58 rotates, the thrombin solution stored in the connecting sleeve 51 will flow into the gelatin sponge 59, so that the gelatin sponge 59 is quickly contaminated with the thrombin solution. When the patient pulls out the puncture catheter, the gelatin sponge 59 can quickly come into contact with the thrombin solution to stop bleeding from the patient's legs, thereby improving the efficiency of stopping bleeding from the patient's legs.

[0042] Advantages of the present invention: The hemostat with thrombin coated on the surface has the following working process:

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 As shown:

[0044] When the medical staff applies pressure to stop bleeding on the patient, the comfort belt 14 is placed under the patient's thigh, and then the pressure regulator 2 is fixed to the patient's thigh through the Velcro 13 and the fixing belt 12, and the pressure regulator 2 is located above the puncture site. Then, according to the depth of the puncture catheter inserted into the patient's thigh and the patient's actual physical condition, the medical staff moves the adjustment slider 31 on the outer wall of the fixing tube 21 for a distance, and moves the adjustment slider 31 to the side of the corresponding scale mark 313. At this time, the medical staff moves the pressing rod 35, and the pressing rod 35 squeezes the return spring 36. The pressing cylinder 32 will be pressed down, and the pressing cylinder 32 will slide downward in the fixed cylinder 21 to squeeze the pressure spring 33, and the bottom of the pressing cylinder 32 will drive the containing tube 5 to move downward, so that the containing tube 5 is pressed toward the puncture site of the patient, and the end of the spring card 34 provided with the protrusion 341 is moved close to the inner wall of the fixed cylinder 21 until the protrusion 341 on the spring card 34 corresponds to the card interface 311 on the adjusting slider 31, and under the restriction of the spring card 34, the pressing rod 35 and the pressing cylinder 32 are restricted in the fixed cylinder 21, so that the pressing cylinder 32 keeps the pressure on the containing tube 5;

[0045] When the medical staff makes the adjusting slider 31 slide on the outer wall of the fixed cylinder 21, the medical staff inserts the resistance plate 47 on the pressure knob 46 into the slide groove 411 in the rotating cylinder 41, and then drives the pressing rod 35 to press through the resistance plate 47. The movement of the adjusting slider 31 will drive the fixed clamping ring 43 to move, and the locking plate 44 on the fixed clamping ring 43 can move in the movable sleeve 42. When the adjusting slider 31 moves to the specified position, the positioning buckle 45 is connected with the limiting hole 441 on the locking plate 44 to achieve the positioning between the movable sleeve 42 and the fixed clamping ring 43. After the medical staff pulls out the puncture catheter of the patient's leg, the pressure knob 46 can be pressed. The pressing knob 46 is inserted into the end surface of the rotating cylinder 41, and then the rotating cylinder 41 is rotated. The rotating cylinder 41 rotates to drive the movable sleeve 42 to move on the fixed cylinder 21 toward the direction of the containing tube 5. The movable sleeve 42 will then drive the locking plate 44 to move the adjusting slider 31. When the adjusting slider 31 moves downward, the spring card 34 is engaged in the card interface 311, and thus can synchronously drive the spring card 34 to move downward. The spring card 34 will continue to squeeze the pressing cylinder 32 under the initial force of the pressing rod 35, so that the pressing cylinder 32 drives the containing tube 5 to apply a greater force toward the patient's leg, thereby tightly pressing the containing tube 5 against the puncture site on the patient's leg.

[0046] When the patient's hemostasis work is completed and the medical staff stops the hemostasis operation on the patient, they only need to move the protrusion 341 in the card interface 311 in the adjusting slide block 31 to separate the spring card 34 from the adjusting slide block 31. Under the action of the pressure spring 33 and the return spring 36, the pressing rod 35 and the pressing cylinder 32 will be reset, thereby stopping the continued pressure. If the contact pressure between the protrusion 341 on the spring card 34 and the card interface 311 is too large, the pressing rod 35 can be moved toward the pressing cylinder 32 again. At this time, the pressing rod 35 is provided with a wedge-shaped inclined surface 343, which will contact the inner wall of the rectangular groove 342 on the spring card 34, and then the spring card 34 is moved downward under the drive of the inclined surface 343. After the spring card 34 moves downward, the protrusion 341 is separated from the card interface 311, thereby realizing the reset operation of the pressing rod 35 and the pressing cylinder 32.

[0047] The gelatin sponge 59 corresponds to the puncture site on the patient's leg, and a thrombin solution is placed in the connecting sleeve 51. When the pressing cylinder 32 is pressed toward the patient's leg, the pressing cylinder 32 moves downward, which will cause the carrying plate 55 to move downward, and the carrying plate 55 will drive the adjusting plate 54 that is clamped to move downward. When the carrying plate 55 moves downward, the arc groove 56 set on the outer wall of the carrying plate 55 will contact the clamping rod 53 on the mounting rod 52, and then drive the carrying plate 55 to rotate under the restriction of the clamping rod 53. When the carrying plate 55 rotates, the adjusting plate 54 will rotate through the limit block 57. The rotation of the adjusting plate 54 will cause the switch knob 58 to rotate. When the switch knob 58 rotates, the thrombin solution stored in the connecting sleeve 51 will flow into the gelatin sponge 59, so that the gelatin sponge 59 is quickly contaminated with the thrombin solution.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Technical personnel in this industry should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not used to limit the present invention.
