Description

Technical Field

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

[0002] Hematology is a discipline centered on blood diseases, mainly including clinical hematology, blood cell morphology, blood immunology, etc. Hematology treatment usually requires surgery, and wounds need to be hemostatic after or during surgery.

[0003] Most of the hemostasis methods in the prior art are still performed by manual pressure by medical staff. In particular, when the amount of bleeding during surgery is too large, the wound needs to be pressed for a long time. This process is relatively laborious, and when the patient's wound bleeds repeatedly, additional medical staff are required to assist the medical staff who press the wound to replace the gauze, resulting in low hemostasis efficiency, and some wounds cannot be pressed for a long time. For example, in the hemostasis work of the brachial artery, the wound needs to be pressed for 10 minutes, then stop pressing, and press again after a period of time. The operation needs to be repeated back and forth, and the medical staff needs to pay attention to the pressing time and the stagnation time at any time. This process consumes a lot of the energy of the medical staff.

[0020] refer to Figures 1 to 12 , a hemostatic device for hematology nursing, comprising a lower arc plate 2, a first expansion plate 1, an upper arc plate 3, a sliding plate 8, a hemostatic sponge 9, a second expansion plate 201, a third expansion plate 24, a driving mechanism, a compression mechanism, a dressing mechanism, and a timing mechanism; Second expansion plates 201 are respectively installed on both sides of the lower arc-shaped plate 2, and legs 202 are respectively installed vertically at both ends of the two second expansion plates 201. The two legs 202 on the same side are fixedly connected by the first expansion plate 1. The lower arc-shaped plate 2 is used to support the bleeding limbs of the patient, and a disposable flexible pad is installed on the upper end thereof to avoid rigid contact between the patient's limbs and the device and to prevent blood from contaminating the device; An upper arc plate 3 is movably installed above the lower arc plate 2. The upper arc plate 3 is driven to slide by the compression mechanism. The upper arc plate 3 will slide under the drive of the compression mechanism to achieve compression and hemostasis of the patient's injured limb; The outer side walls of the two first expansion plates 1 are respectively provided with timing mechanisms, and the compression mechanism is driven to work by the timing mechanism. The compression mechanism will periodically compress the injured limb of the patient under the drive of the timing mechanism, thereby avoiding manual compression and relaxation by the doctor; A sliding plate 8 is movably installed below the upper arc plate 3. The top wall of the sliding plate 8 is an arc surface that cooperates with the upper arc plate 3. The sliding plate 8 is used to install a hemostatic sponge 9. The hemostatic sponge 9 is driven by the compression mechanism to compress the injured and bleeding limb of the patient. The sliding plate 8 is driven to slide by the dressing changing mechanism, and the sliding plate 8 will also slide out of the upper arc-shaped plate 3 under the drive of the dressing changing mechanism, so that the doctor can replace the hemostatic sponge 9 conveniently; The upper arc plate 3 drives the dressing changing mechanism to work by sliding; A hemostatic sponge 9 is movably mounted at the lower end of the sliding plate 8, and the hemostatic sponge 9 is disposable; A third expansion board 24 is fixedly installed between the two first expansion boards 1; A driving mechanism is installed on the third expansion board 24; The timing mechanism is driven by the driving mechanism, and the driving mechanism provides driving force for the timing mechanism.

[0021] The pressing mechanism comprises a fourth expansion plate 4, a first guide rod 5, a first connecting rod 11, a first rectangular slider 19, an incomplete gear 12, a rack plate 13, and a second guide rod 17; The first ends of the first guide rods 5 are respectively vertically mounted on both sides of the upper ends of the two second expansion plates 201; The fourth expansion plates 4 are respectively installed on the two side walls of the upper arc plate 3; The two first guide rods 5 located on the same side are respectively slidably arranged to penetrate the two ends of the fourth expansion plate 4 located on the same side; First rectangular sliding grooves 401 are respectively provided on both sides of the two fourth expansion plates 4; The first rectangular sliding blocks 19 are slidably installed in the two first rectangular sliding grooves 401 respectively; First connecting columns are respectively installed on the outer walls of the two first rectangular sliding blocks 19, and the first ends of the first connecting rods 11 are rotatably mounted on the outer sides of the two first connecting columns; An incomplete gear 12 is fixedly mounted on the outer sides of the second ends of the two first connecting rods 11; The lower ends of the two incomplete gears 12 are respectively meshed with rack plates 13; The two rack plates 13 are slidably disposed on the upper ends of the two first expansion plates 1 respectively; A second guide rod 17 is slidably installed in each of the two rack plates 13; The two ends of the second guide rod 17 located on the same side are respectively fixed between the two legs located on the same side; Both rack plates 13 are driven to slide by the timing mechanism. Driven by the timing mechanism, the two rack plates 13 will slide back and forth on the first expansion plate 1, and drive the incomplete gear 12 meshing therewith to start reciprocating rotation during the sliding process. The two incomplete gears 12 drive the first connecting rods 11 on both sides to start reciprocating rotation during the reciprocating rotation. The two first connecting rods 11 drive the first rectangular sliders 19 on both sides to start reciprocating sliding along the first rectangular slide grooves 401 on both sides during the reciprocating rotation. Since the sliding trajectory of the upper arc plate 3 has been fixed by the first guide rod 5, when the first rectangular sliders 19 on both sides are in the process of reciprocating sliding, the upper arc plate 3 can only slide up and down, thereby achieving compression of the patient's injured limbs.

[0022] The timing mechanism comprises a baffle 102, a return spring 18, a second rectangular slider 22, a second connecting rod 14, a third rectangular slider 23, a third connecting rod 15, a fourth rectangular slider 21, a fifth rectangular slider 20, and a disc 16; The upper ends of the two first expansion plates 1 are respectively installed with baffles 102, and the two second guide rods 17 are respectively arranged to penetrate the two baffles 102; The first ends of the two rack plates 13 are respectively in detachable contact with the front walls of the two baffles 102; The second ends of the two rack plates 13 are respectively mounted with the first ends of the return springs 18; The second ends of the two return springs 18 are respectively fixedly mounted with second rectangular sliders 22; The two second rectangular sliding blocks 22 are respectively slidably disposed on the upper ends of the two first expansion plates 1, and the two second rectangular sliding blocks 22 are respectively slidably penetrated with the two second guide rods 17; Two return springs are respectively sleeved on the outer sides of the two second guide rods 17; Second connecting shafts are respectively installed on the outer walls of the two second rectangular sliding blocks 22, and the first ends of the second connecting rods 14 are rotatably mounted on the two second connecting shafts. The outer side walls of the two first expansion plates 1 are respectively provided with second rectangular sliding grooves 101, and the third rectangular sliding blocks 23 are respectively slidably installed in the two second rectangular sliding grooves 101; The outer walls of the two third rectangular sliding blocks 23 are respectively mounted with third connecting shafts, and the second ends of the two second connecting rods 14 are respectively rotatably sleeved on the two third connecting shafts; The outer ends of the two third connecting shafts are respectively installed with first connecting blocks 2301, and the two first connecting blocks 2301 are respectively arranged on the outer sides of the two second connecting rods 14; Fourth connecting shafts are fixedly mounted on the outer sides of the two first connecting blocks 2301, and fourth rectangular sliding blocks 21 are rotatably mounted on the two fourth connecting shafts. The first ends of the third connecting rods 15 are rotatably mounted on the outer side walls of the two first expansion plates 1 through the first rotating shaft, and the first ends of the two third connecting rods 15 are respectively arranged on the left sides of the two second rectangular sliding grooves 101; The two third connecting rods 15 are respectively provided with a first rectangular through slot 1501 and a second rectangular through slot 1502, wherein the first rectangular through slot 1501 is provided at a side close to the second rectangular sliding slot 101; The two fourth rectangular sliding blocks 21 are slidably installed in the two first rectangular through grooves 1501 respectively; Discs 16 are rotatably mounted on the outer side walls of the two first expansion plates 1 through the second rotating shaft, and the discs 16 on the same side are respectively mounted between the second rectangular chute 101 and the first rotating shaft on the same side; Fourth connecting shafts are respectively installed at eccentric positions on the outer walls of the two discs 16; The two fourth connecting shafts are respectively rotatably mounted with fifth rectangular sliders 20, and the two fifth rectangular sliders 20 are respectively slidably mounted in the two second rectangular through grooves 1502; The two disks 16 are driven to rotate by the driving mechanism. The two disks 16 will rotate under the drive of the driving mechanism, and in the process of rotation, the fourth connecting shaft at the eccentric position thereof will start to rotate. In the process of rotation, the fourth connecting shaft will drive the fifth rectangular slider 20 mounted thereon to start to rotate. Since the fifth rectangular slider 20 reciprocates along the second rectangular through groove 1502 while rotating around the disk 16, it is converted into enabling the third connecting rod 15 to swing up and down. In the process of swinging up and down, the third connecting rods 15 on both sides drive the fourth connecting rods 20 located in the first rectangular through groove 1501. The rectangular slider 21 starts to slide back and forth along the first rectangular through groove 1501. Since the third connecting rod 5 is in an up and down swinging state, the third rectangular slider 23 fixedly connected to the fourth rectangular slider 21 starts to slide up and down along the second rectangular slide groove 101, and drives the second connecting rod 14 to start to deflect up and down during the sliding process. The second connecting rods 14 on both sides drive the second rectangular sliders 22 on both sides to slide back and forth along the second guide rod 17 during the up and down deflection process. The rack plate 13 connected to the second rectangular slider 22 via the return spring 18 now has the ability to slide back and forth. Figure 2 When the second rectangular slider 22 slides to the right, the reset spring 18 and the rack plate 13 will slide to the right driven by the second rectangular slider 22. When the rack plate 13 touches the baffle 102, the second rectangular slider 22 begins to compress the reset spring 18. At this time, the upper arc plate 3 is already in a compressed state. When the second rectangular slider 22 slides to the right limit position, it begins to slide to the left. At this time, the reset spring 18 gradually resets until it starts to pull the rack plate 13 to start sliding to the left. At this time, the upper arc plate 3 is gradually lifted up to relax.

[0023] The driving mechanism comprises a driving shaft 25, a first helical gear 26, a second helical gear 27, and a driving motor 28; The same driving shaft 25 is fixedly installed between the two second rotating shafts, and the two ends of the driving shaft 25 rotate and penetrate the two first expansion plates 1 and are fixedly connected to the two second rotating shafts; A first helical gear 26 is fixedly mounted on the middle end of the driving shaft 25; The lower end of the first helical gear 26 is meshed with a second helical gear 27, and the second helical gear 27 is rotatably mounted on the rear wall of the third expansion plate 24 via a third rotating shaft; A driving motor 28 is installed on the front wall of the third expansion board 24; The output shaft of the driving motor 28 rotates and passes through the third expansion plate 24 and is fixedly connected to the third rotating shaft; The first helical gear 26 and the second helical gear 27 are both helical gears with an inclination angle of 45°; The driving motor 28 is a servo motor with controllable speed. Its function is to facilitate the doctor to control the speed of the motor in real time. This is the prior art and will not be elaborated here. After the doctor starts the driving motor 28 and sets the speed, the output shaft of the driving motor 28 starts to rotate and drives the second helical gear 27 fixedly mounted thereon. The second helical gear 27 drives the first helical gear 26 meshing therewith through rotation. The thread rotation direction of the first helical gear 26 and the second helical gear 27 is 45°, which facilitates the transmission of vertically staggered axes therebetween. During the rotation process, the first helical gear 26 drives the driving shaft 25 coaxially mounted therewith to start rotating, and the disc 16 fixedly mounted at both ends of the driving shaft 25 now has the ability to rotate.

[0024] The dressing changing mechanism comprises a fixing block 7, a fourth connecting rod 6, a connecting plate 10, a prismatic rod 1002, and a hinge block 1001; The second ends of the two first guide rods 5 close to the second rectangular slide groove 101 are respectively fixed with fixing blocks 7; The inner side walls of the two fixing blocks 7 are respectively mounted with fifth connecting shafts; The outer sides of the two fifth connecting shafts are rotatably sleeved with the first ends of the fourth connecting rods 6; A third rectangular sliding groove 402 is respectively provided at one end of the two fourth expansion plates 4 close to the fixing block 7; The connecting plates 10 are slidably installed in the two third rectangular sliding grooves 402 respectively; A hinge block 1001 is respectively installed on the upper part of the first end of the two connecting plates 10; The second ends of the two fourth connecting rods 6 are rotatably disposed on the outer walls of the two hinge blocks 1001 respectively; Prismatic rods 1002 are respectively installed on the rear walls of the second ends of the two fourth connecting rods 6; Rectangular through slots 4021 that cooperate with the prismatic rods 1002 are respectively provided on the rear walls of the two third rectangular slide slots 402; The two prismatic rods 1002 are slidably installed in the two rectangular through slots 4021 respectively; The lower ends of the upper arc-shaped plate 3 are provided with slots 302 on both sides thereof; The two sides of the slide plate 8 are respectively slidably engaged in the two slots 302; Second connection blocks 801 are respectively installed on both sides of one end of the slide plate 8 close to the fixed block 7, and the rear walls of the two second connection blocks 801 are respectively in detachable contact with both sides of the front wall of the upper arc-shaped plate 3; The second ends of the two connecting plates 10 are fixedly connected to the outer walls of the two second connecting blocks 801 through second connecting columns, respectively. Figure 2When the upper arc plate 3 slides upward again, the distance between the fourth expansion plates 4 on both sides and the fixed blocks 7 on both sides becomes shorter, so the fourth connecting rods 6 on both sides start to rotate upward. During the upward rotation, the fourth connecting rods 6 on both sides drive the connecting plates 10 on both sides to start to slide out to the left. The prismatic rod 1002 fixedly connected to the connecting plate 10 now slides in the rectangular through groove 4021 that cooperates with it. The cooperation between the rectangular through groove 4021 and the prismatic rod 1002 ensures the sliding trajectory of the connecting plate 10 and will not fall off during the sliding process. As the two connecting plates 10 slide to the left, the second connecting block 801 fixedly connected thereto also starts to slide to the left. The slide plate 8 fixedly installed between the two second connecting blocks 801 can now drive the hemostatic sponge 9 to slide out to the left, making it convenient for the doctor to replace the hemostatic sponge 9.

[0025] The upper arc plate 3 is provided with a plurality of observation slots 301 for conveniently observing the bleeding situation; The slide plate 8 is made of a transparent material, and the doctor can observe the bleeding of the hemostatic sponge 9 through the groove 301 and the transparent slide plate 8, and can adjust the rotation speed of the servo motor in time to flexibly change the compression frequency.

[0026] An arc-shaped mounting plate 902 is installed at the upper end of the hemostatic sponge 9, and a vertical plate of a T-shaped slider 901 is installed at the middle of the upper end of the arc-shaped mounting plate 902; The lower end of the sliding plate 8 is provided with a T-shaped slide groove that cooperates with the T-shaped slider 901. The cross plate of the T-shaped slider 901 is detachably slidable in the T-shaped slide groove. The cooperation between the T-shaped slider 901 and the T-shaped slide groove ensures that the hemostatic sponge 9 can only move horizontally. Figure 2 When the sliding plate 8 slides downward and to the right, the lower end of the hemostatic sponge 9 first contacts the patient's wound. When the hemostatic sponge 9 is subjected to pressure, in order to avoid the force to the right pulling the patient's wound, the hemostatic sponge 9 will be fixed on the patient's wound under the action of downward pressure, and at the same time, relative sliding will occur between the sliding plate 8, so that the hemostatic sponge 9 can always be located at the bleeding site of the patient's injured limb.

[0027] Implementation method of the present invention: Place the device on a horizontal surface, lay the disposable flexible pad on the lower arc plate 2, and adjust the device to the initial state. In the initial state of the device, refer to Fig.12 A, the upper arc plate 3 is located directly above the lower arc plate 2, and the sliding plate 8 now extends out of the upper arc plate 3 and is located at the front side of the upper arc plate 3; The user slides the disposable hemostatic sponge 9 under the sliding plate 8; Example

[0028] When the patient's bleeding site needs long-term pressure to stop bleeding, the doctor adjusts the servo motor, sets the motor speed, and then sets a timer to shut it down; The injured limb of the patient is placed on the disposable flexible pad on the lower arc plate 2, and the servo motor is started. At this time, the upper arc plate 3 drives the sliding plate 8 to slide downward at a set speed. At the same time, during the downward sliding of the upper arc plate 3, the sliding plate 8 drives the hemostatic sponge 9 to be gradually retracted into the upper arc plate 3; As the upper arc plate 3 continues to slide downward, the hemostatic sponge 9 first contacts the patient's injured limb. At this time, the rack plate 13 contacts the baffle 102, and the motor is shut down at a fixed time. At this time, the upper arc plate 3 provides downward pressure on the patient's limb. After contacting the patient's injured limb, the hemostatic sponge 9 fits with the patient's limb and remains motionless, thereby achieving long-term compression and hemostasis. Example

[0029] When the patient's bleeding site requires intermittent compression to stop bleeding, the doctor can adjust the speed of the servo motor according to the bleeding situation. The faster the motor speed, the higher the pressing frequency, and the slower the motor speed, the lower the pressing frequency. Place the patient's injured limb on the disposable flexible pad on the lower arc plate 2, start the servo motor, and when the rack plate 13 contacts the baffle 102, refer to Figure 2 The servo motor is still working, and according to the set speed, the second rectangular slider 22 compresses the reset spring 18 at a certain speed. Before the second rectangular slider 22 moves to the rightmost side, the rack plate 13 has already contacted the baffle 102 and will not move to the right any more, so the upper arc plate 3 is always in a compressed state and will not move. When the second rectangular slider 22 starts to move to the left, until the reset spring 18 is completely reset, the rack plate 13 will follow the second rectangular slider 22 to start moving to the left, and the upper arc plate 3 will be lifted up and opened. Through the continuous rotation of the motor, the above-mentioned intermittent compression hemostasis work can be repeatedly completed.

[0030] The doctor can observe the bleeding of the hemostatic sponge in real time through the transparent slide plate 8 and the observation slot 301 to determine whether the hemostatic sponge needs to be replaced; When the hemostatic sponge begins to bleed, the doctor can wait for the moment when the upper arc plate 3 is lifted upward. When the upper arc plate 3 is lifted upward, the hemostatic sponge 9 is separated from the patient's injured limb, and the slide plate 8 drives the hemostatic sponge 9 to slide out in front of the upper arc plate. The doctor can remove the bleeding hemostatic sponge 9 and replace it with a new one.

[0031] The compression mechanism of the present invention can periodically realize the two tasks of compression and relaxation with the cooperation of the timing mechanism. When the timing mechanism of the present invention drives the compression mechanism to be in a relaxed state, the dressing change mechanism is started at the same time, which is convenient for doctors to replace hemostatic sponges and change dressings. The servo motor in the present invention can adjust the rotation speed, which is convenient for controlling the hemostatic cycle and is more flexible to use.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
