Description

Technical Field

[0001] The invention belongs to the technical field of cardiovascular instruments, and in particular relates to a convergent discrete pressing hemostasis device. Background Art

[0002] The heart is a hollow muscular organ located in the middle of the chest cavity. It is divided into two left and right chambers by a partition. Each chamber is divided into two parts: the atrium in the upper part and the ventricle in the lower part. The atrium collects blood into the heart, and the ventricle ejects blood out of the heart. There are valves at the inlet and outlet of the ventricle to ensure one-way flow of blood. Under different physiological conditions, the metabolic levels of various organs and tissues of the human body are different, and the needs for blood flow are also different.

[0003] In the prior art (the patent application with publication number CN110960284B and patent name of compression hemostasis device), compression hemostasis can be performed on different areas to be hemostatically controlled, and the compression strength can be adjusted while pressing the exact location of the bleeding point of the blood vessel to achieve the expected hemostatic effect. In the process of implementing this technical solution, it is found that the prior art has at least the following problems.

[0004] When cardiovascular doctors perform emergency hemostasis on the patient's affected limb, they usually use pressure to stop bleeding. During this period, although the bleeding point of the affected limb can be stopped by adjusting the pressing force, before and after hemostasis, as the patient's posture changes, the affected limb also moves, and the stability is poor. It is easy to shift from the bleeding point of the affected limb, or even leave the position of the bleeding point, causing secondary bleeding, which increases the difficulty for cardiovascular doctors to stop bleeding from the patient's affected limb for the second time.

[0040] Both sides of the inner cavity of the top frame 3 are provided with adjustment components 5 and pressing components 6 used in conjunction with the square frame 2, and the adjustment component 5 includes a micro servo motor 51 embedded in the center of the top frame 3 and used as a unified driving source to achieve the mechanical compression hemostasis effect of the bleeding point of the patient's affected limb; an inflation component 7 is provided on the cylinder 4, and both sides of the square frame 2 are provided with auxiliary components 8 used in conjunction with the inflation component 7, which not only achieve the pneumatic compression hemostasis effect of the bleeding point of the patient's affected limb, but also blow the affected limb area extended into the opening groove 10 to achieve ventilation and heat dissipation.

[0041] like Figure 5-Figure 9As shown, the adjustment component 5 also includes a micro electric push rod 52 embedded in the output shaft of the micro servo motor 51, and the piston rod of the micro electric push rod 52 is fixedly connected with a locking head 53, and the center of the inner cavity of the top frame 3 is rotatably connected with a main synchronous wheel 54, and the top of the main synchronous wheel 54 is provided with a locking groove 55 that is engaged with the locking head 53. The micro servo motor 51 first provides a unified driving source to save power costs, and the micro electric push rod 52 adjusts the engagement stroke between the locking head 53 and the locking groove 55. The outer side of the main synchronous wheel 54 is connected with two groups of slave synchronous wheels 56 through a synchronous belt transmission, and then the locking head 53 that is engaged in place drives the main synchronous wheel 54 to rotate accordingly. The main synchronous wheel 54 drives the two groups of slave synchronous wheels 56 to rotate synchronously through the synchronous belt, so as to provide a synchronous driving force for the mechanical compression hemostasis method of the bleeding point of the patient's affected limb;

[0042] The pressing assembly 6 includes two groups of positive and negative threaded rods 61 fixed to the bottom of the synchronous wheels 56 and rotatably connected to the square frame 2. The two groups of synchronous wheels 56 first drive the two positive and negative threaded rods 61 to rotate synchronously, and the upper and lower sides of the positive and negative threaded rods 61 are threadedly connected with threaded sleeves 62. The two positive and negative threaded rods 61 realize synchronous inward and outward displacement through the upper and lower groups of threaded sleeves 62. The inner side of the threaded sleeve 62 is fixedly connected with a support plate 63 that slidably cooperates with the square frame 2, and the inner side of the support plate 63 is fixedly connected with a silicone seat 64, and the inner side of the silicone seat 64 is fixedly connected with a pressing plate 65, and the inner side of the pressing plate 65 is connected with a hemostatic bag 66. The threaded sleeve 62 then drives the two groups of pressing plates 65 to mechanically press the bleeding point of the affected limb through the silicone seats 64 on the two groups of support plates 63, and the silicone seat 64 and the hemostatic bag 66 provide flexible protection for the affected limb, so as to achieve the mechanical pressing and hemostasis effect of the bleeding point of the patient's affected limb;

[0043] The pressing plate 65 adopts an arc-shaped hollow structure design, which is conducive to supplying air into the pressing plate 65 to reach the hemostatic bag 66, and the hemostatic bag 66 is distributed in an array along the central axis of the pressing plate 65. The hemostatic bag 66 adopts an oblate shape design to tightly cover and press the bleeding point of the affected limb and the surrounding skin.

[0044] The inflation assembly 7 includes a main circular gear 71 fixed on the output shaft of the micro servo motor 51, and both sides of the main circular gear 71 are meshed with slave circular gears 72. The main circular gear 71 first drives the two groups of slave circular gears 72 to rotate. The slave circular gear 72 is fixedly connected with a concave rod 73 that rotates with the top frame 3. The two groups of slave circular gears 72 drive the two concave rods 73 to rotate accordingly, and the center of the concave rod 73 is rotatably connected with a connecting rod frame 74, and the other end of the connecting rod frame 74 is hinged with a piston head 75 that slides with the cylinder barrel 4. The two concave rods 73 drive the piston heads 75 on the two connecting rod frames 74 to alternately reciprocate in the two groups of cylinder barrels 4, and generate an inflation gas source in the two groups of cylinder barrels 4, and the exhaust port of the cylinder barrel 4 is connected with a supply pipe 76, which is then transported by two supply pipes 76 to provide an inflation source for the pneumatic compression hemostasis method of the bleeding point of the patient's affected limb.

[0045] The air inlet of the cylinder barrel 4 is connected to an air inlet pipe with an air inlet valve, which is beneficial to the air inlet work of the cylinder barrel 4, and an exhaust valve is provided at one end of the supply pipe 76 close to the cylinder barrel 4, which is beneficial to the exhaust work of the cylinder barrel 4, and both the air inlet valve and the exhaust valve are electric valves;

[0046] The auxiliary component 8 includes a small pressure storage tank 81 connected to the bottom end of the supply pipe 76 and fixed to the outside of the square frame 2. The two-way inflation sources in the two supply pipes 76 are first supplied to the two groups of small pressure storage tanks 81 for temporary storage, and both ends of the small pressure storage tanks 81 are connected to three-way valves 82, and the upper and lower ends of the three-way valve 82 are connected to telescopic pipes 83, and the other end of the telescopic pipe 83 is connected to a four-way pipe 84 that is connected and matched with the pressing plate 65 and the hemostatic bag 66. Then, the inflation sources temporarily stored in the two groups of small pressure storage tanks 81 are supplied to the four-way pipe 84 through the telescopic pipes 83 on the two groups of three-way valves 82. The air source is supplied into the array-distributed hemostatic bag 66 through the pressing plate 65 with an arc-shaped hollow structure design to expand it, and perform secondary flexible compression hemostasis on the bleeding point of the affected limb after mechanical compression, and closely fit the bleeding point of the affected limb and the surrounding skin to achieve the pneumatic compression hemostasis effect of the bleeding point of the patient's affected limb. The outer end of the four-way tube 84 is connected to the arc tube 85, and the inner end of the arc tube 85 is connected to the nozzle 86. Another air source in the four-way tube 84 passes through the arc tube 85 and is blown toward the affected limb area in the square frame 2 by the nozzle 86 distributed in an inclined divergent shape, which plays a role in ventilation and heat dissipation.

[0047] The arc tubes 85 are distributed in an axisymmetric state along the central axis of the square frame 2, and the air jets 86 on the arc tubes 85 are distributed in an inclined divergent shape toward the square frame 2, so as to evenly supply air and dissipate heat to the areas on both sides of the affected limb extending into the square frame 2.

[0048] like Fig.10 and Fig.11As shown, before using gauze to press and stop bleeding on the bleeding point of the patient's affected limb, it is necessary to apply hemostatic agents to the bleeding point area of ​​the affected limb. This process is generally manually applied to the bleeding point area by medical staff, which takes a long time to stop bleeding and is not conducive to rapid pressing and stopping bleeding care. A spraying component 9 used in conjunction with a small pressure storage tank 81 is arranged in front of the square frame 2, and the spraying component 9 includes a pressurizing pipe 91 connected to the outer end of the small pressure storage tank 81, and the inner end of the pressurizing pipe 91 is connected to a four-way joint 92. The inflation source temporarily stored in the two groups of small pressure storage tanks 81 is first pressurized by the two pressurizing pipes 91 and then supplied to the four-way joint 92;

[0049] The top of the four-way joint 92 is connected to a tightening seat 93, the inner cavity of the tightening seat 93 is threadedly connected to a tightening head 94, and the top of the tightening head 94 is connected to a medicine storage pot 95, which provides hemostatic agent supply. A liquid level sensor 96 is embedded in the top of one side of the medicine storage pot 95 to monitor the hemostatic agent level in the medicine storage pot 95 in real time, and the bottom end of the four-way joint 92 is connected to an annular tube 97, and the inner cavity of the annular tube 97 is connected to a spray head 98 on all sides, and the hemostatic agent in the medicine storage pot 95 is also supplied to the four-way joint 92, and is pressurized after merging with the inflation source and then supplied to the annular tube 97. Finally, the circumferentially distributed spray heads 98 pre-spray the bleeding points of the inserted affected limb and the skin in the surrounding area for hemostasis, which facilitates subsequent compression to stop bleeding.

[0050] The working principle of a convergent discrete pressing hemostasis device is as follows: first, the micro servo motor 51 is controlled to start in advance and drive the main circular gear 71 to rotate, and the main circular gear 71 drives the concave rods 73 on the two groups of slave circular gears 72 to rotate accordingly, and the two concave rods 73 drive the piston heads 75 on the two connecting rod frames 74 to perform alternating reciprocating work in the two groups of cylinder barrels 4, and the inflation source generated in the two groups of cylinder barrels 4 is supplied to the two groups of small pressure storage tanks 81 through two supply pipes 76 for temporary storage, until the two groups of small pressure storage tanks 81 are full, and then the micro servo motor 51 is controlled to pause;

[0051] Prior to this, first screw the tightening head 94 on the medicine storage pot 95 into the tightening seat 93 on the four-way joint 92, and then fill the hemostatic agent through the filling port on the medicine storage pot 95, and the hemostatic agent in the medicine storage pot 95 is also supplied to the four-way joint 92. At the same time, the bleeding point of the patient's affected limb is extended into the spray head 98 area of ​​the annular tube 97, and the inflation source in the two groups of small pressure storage tanks 81 is uniformly supplied to the four-way joint 92 through the two pressurizing pipes 91, and merged with the supplied hemostatic agent. Then, the pressurized hemostatic agent in the four-way joint 92 passes through the spray heads 98 distributed circumferentially on the annular tube 97, and is evenly and comprehensively sprayed to the bleeding point of the patient's affected limb and the surrounding skin area for hemostasis and sterilization, and the liquid level sensor 96 monitors the liquid level of the hemostatic agent in the medicine storage pot 95 in real time, so as to add the hemostatic agent in time.

[0052] After the bleeding point of the patient's affected limb and the surrounding skin are sprayed with hemostatic agents and wrapped with hemostatic gauze, the patient continues to extend into the open slot 10, and after the bleeding point of the affected limb is located inside the hemostatic bag 66 on any group of pressing plates 65, the micro electric push rod 52 is first controlled to open and drive the locking head 53 to move down and clamp into the locking slot 55 on the main synchronous wheel 54, and then the micro servo motor 51 is controlled to open again and drive the main synchronous wheel 54 to rotate through the locking head 53 that is clamped in place, and the main synchronous wheel 54 drives the two groups of slave synchronous wheels 56 to rotate synchronously with it through the synchronous belt;

[0053] The two groups of slave synchronous wheels 56 drive the two positive and negative threaded rods 61 to rotate synchronously, and the two positive and negative threaded rods 61 drive the upper and lower groups of threaded sleeves 62 to move synchronously inward, and the upper and lower groups of threaded sleeves 62 drive the two groups of support plates 63 to move synchronously inward accordingly, and the two groups of support plates 63 drive the two groups of pressing plates 65 on the silicone seats 64 to move toward the affected limb, and the two groups of silicone seats 64 play a flexible buffering role for the two groups of pressing plates 65, until the two groups of pressing plates 65 drive the two rows of array-shaped hemostatic capsules 66 to move inward to the bleeding point of the affected limb and the surrounding skin, the hemostatic capsules 66 on one group of pressing plates 65 press and cover the bleeding point on the affected limb, and the hemostatic capsules 66 on the other group of pressing plates 65 support the lower part of the affected limb, so that the mechanical compression hemostasis care of the bleeding point of the affected limb can be completed;

[0054] After the mechanical compression hemostasis care of the bleeding point of the affected limb is completed, the air source in the two groups of small pressure storage tanks 81 is supplied to the telescopic tube 83 through the two groups of three-way valves 82 in the open state, and then supplied to the four-way tube 84 through the telescopic tube 83 that moves and contracts with the pressing plate 65. The air source in the four-way tube 84 is supplied to the two rows of array-distributed hemostatic bags 66 through the two groups of pressing plates 65 with an arc-shaped hollow structure design, and expands them. The expanded two rows of hemostatic bags 66 further perform pneumatic compression on the bleeding point and the lower part of the affected limb. The pneumatic compression hemostasis care of the bleeding point of the affected limb can be completed by forcing the support and making the two rows of hemostatic bags 66 formed by the flat circle fit tightly to the bleeding point and the lower area of ​​the patient. At the same time, another inflation source in the four-way pipe 84 blows gas toward the square frame 2 through the arc pipe 85 by the nozzle 86, so as to ventilate and dissipate the affected limb which is extended into the open groove 10 and is in the state of compression hemostasis, and the heat dissipation groove 11 opened on the square frame 2 ventilates and circulates the heat until the hemostasis care of the bleeding point of the affected limb is completed.
