Description

Technical Field

[0001] The invention relates to the medical field, in particular to a medical hemostatic compressor. Background Art

[0002] During surgery, patients usually need to have an arterial puncture to administer anesthetics, and after surgery they need to apply pressure to the puncture site to stop bleeding, which usually takes a long time, up to several hours.

[0003] In the prior art, the compressor is fixed to the patient's limb by a fixing belt. According to the doctor's advice, the knob is rotated after several hours to reduce the pressure. However, after reducing the pressure, the tightness of the fixing belt will also decrease, which will cause the compression position to deviate easily. Frequent adjustment of the tightness of the fixing belt is very inconvenient. Removing the fixing belt and readjusting it many times will also reduce the compression effect and the recovery speed of the puncture point. Summary of the invention

[0004] The present invention is intended to provide a medical hemostatic compressor, which can reduce the tightness of a fixing belt after reducing the pressing force.

[0005] To achieve the above object, the present invention adopts the following technical solution: a medical hemostatic compressor, comprising an inflatable pressing unit and a mechanical pressing unit, wherein the inflatable pressing unit is arranged at the center of the inflatable pressing unit;

[0006] The mechanical pressing unit includes a sleeve and a threaded rod connected in a threaded manner. A tightening piece is provided at the lower end of the threaded rod, and the tightening piece is used to press the puncture point. The inflatable pressing unit includes a shell, and an inflatable cavity and an inflatable component are provided in the shell. An air film is provided on the lower side of the inflatable cavity. The inflatable component is used to inflate air into the inflatable cavity. The air film bulges under the action of air pressure, and the air film is used to press the surrounding position of the puncture point.

[0007] The beneficial effects of this program are:

[0008] 1. In the initial state, by rotating the threaded rod, the abutment piece presses the puncture point to achieve hemostasis;

[0009] After several hours, rotate the threaded rod to reduce the pressing force. At this time, the inflation component is inflated to make the air film swell, increasing the pressure of the air film on the surrounding position of the puncture point, thereby maintaining the tightness of the fixing belt and preventing the tightness of the fixing belt from decreasing.

[0010] 2. In the prior art, only a mechanical pressing unit is used for pressing, and a dent mark is formed around the pressing area, which can easily cause discomfort to the patient, especially to the patient with poor physical condition, and the dent cannot be restored for a long time; in this solution, an inflatable pressing unit is arranged around the mechanical pressing unit to form a transition between the mechanical pressing area and other areas, avoiding the formation of dent marks and improving the patient's comfort.

[0011] 3. The inventor has considered canceling the mechanical pressing unit and using only the inflatable pressing unit. However, since the pressing area of ​​the inflatable pressing unit is large, the position of the maximum pressure cannot be determined and effective pressing cannot be formed. Therefore, a combination of two pressing units is adopted. First, the puncture point is accurately pressed by the mechanical pressing unit to complete the pressing positioning. At the same time, it can also prevent the patient from accidentally touching the compressor and causing displacement. Then, the airbag is inflated to bulge. The closer the air film is to the edge, the smaller the bulge is, thus forming a transition to ensure the comfort of the patient.

[0012] Furthermore, a pressing block is provided at the center position of the lower side of the air film, and the shapes of the lower side of the pressing piece and the upper side of the pressing block match each other, so that the pressing piece presses against the puncture point by pressing against the pressing block.

[0013] Furthermore, a sliding cavity is vertically provided in the threaded rod, a sliding rod is provided on the upper side of the pressing block, the upper end of the sliding rod passes through the air film and the abutment and is inserted into the sliding cavity, the sliding rod, the abutment and the sliding cavity are slidably connected, and the bottom of the sliding rod and the air film are sealed.

[0014] Furthermore, a limiting portion is provided at the upper end of the slide rod, and the limiting portion is used to limit the slide rod from sliding out of the slide groove.

[0015] Furthermore, the center position of the upper side of the pressing block is connected to the sliding rod, and the remaining position of the upper side of the pressing block is bonded to the lower surface of the air film.

[0016] Furthermore, the lower side of the fastening member and the upper side of the pressing block are both arc-shaped.

[0017] Furthermore, an air inlet cavity is provided in the shell, and the air inlet cavity is connected to the inflation cavity. The inflation component includes a sealing plate, and an elastic member is provided between the upper side of the sealing plate and the air inlet cavity. The sealing plate is used to press the gas in the air inlet cavity into the inflation cavity.

[0018] Furthermore, the threaded rod includes a base section and an engaging section from top to bottom, and the base section is threadedly connected to the sleeve; the inflation component also includes a first gear, a transmission shaft, a second gear and a vertical rack, the engaging section is meshed with the first gear, and the two ends of the rotating shaft are respectively connected to the center of the first gear and the second gear, the radius of the second gear is larger than the first gear, the second gear is meshed with the vertical rack, the upper end of the vertical rack is connected to the sealing plate, and the lower end of the vertical rack is inserted into the bottom side of the air intake chamber and is slidably connected to the bottom side of the air intake chamber.

[0019] Furthermore, a one-way valve and a pressure valve are provided on the side wall of the air inlet chamber. The one-way valve is used to inflate the air inlet chamber from the outside, and the pressure valve is used to release excess pressure in the pressure chamber.

[0020] This solution also has the following effects:

[0021] 1. Since the air film is in direct contact with the patient's skin, if a pressing piece is used to press against the puncture point, the pressing piece needs to press against the inner side of the air film first, and then press against the puncture point through the air film; however, pressing against the air film directly in this way makes the air film bulge locally, which is easy to damage the air film production;

[0022] In this solution, a pressing block is set in advance under the air film. In the initial state, the position where the pressing block is set on the air film is recessed, and then the clamping member presses the air film and the pressing block downward to reduce the degree of recess, thereby avoiding the situation where the air film is partially bulged and preventing the clamping member from damaging the air film.

[0023] 2. To fix the pressing block and prevent it from shaking when it is not in use, and to accurately locate the puncture point when it is in use, a sliding rod is provided on the upper side of the pressing block, and the sliding rod is inserted into the sliding cavity to limit the horizontal direction, so that only the pressing block and the sliding rod are allowed to move vertically relative to the sliding cavity, and a limiting part is provided to prevent the sliding rod from sliding out;

[0024] Since the slide bar needs to pass through the air film, the part between the air film and the slide bar needs to be sealed. This solution adopts a method of bonding the upper side of the pressing block and the lower surface of the air film, and uses a sealant for sealing.

[0025] 3. If a motor or fan is used to blow air directly into the inflation cavity, it is obviously too costly and unnecessary, and these devices are directly connected to the compressor and are not convenient for the patient to move;

[0026] Therefore, in this solution, the gas is first passed into the air intake chamber through the one-way valve for storage. In the subsequent pressure adjustment process, there is no need to introduce additional gas. When you want to reduce the pressing force, rotate the threaded rod to drive the clamping member to move upward, which in turn drives the first gear, the transmission shaft and the second gear to rotate. The second gear drives the vertical rack and the sealing plate to move downward, thereby pressing the gas in the air intake chamber into the inflation chamber, causing the air film to further swell. This can not only make up for the gas leakage under long-term air pressure, but also make up for the loosening of the fixing belt caused by the reduction in the force of the threaded rod.

[0027] 4. Since the threaded rod and the first gear are worm gear structures, the transmission motion is irreversible, and the first gear cannot drive the threaded rod to rotate in the reverse direction. Therefore, when the patient's puncture point swells, the reverse squeezing of the air film will not drive the sealing plate to move upward and will be blocked by the threaded rod. The excess air pressure can only be released through the pressure relief valve;

[0028] This prevents the sealing plate from driving the vertical rack, the second gear, the transmission shaft, and the first gear to move in sequence, and prevents the threaded rod from being driven downward to press against the puncture point and deteriorate the puncture point.

[0036] Example 1

[0037] like Figure 1 As shown: a medical hemostatic compressor, which cooperates with a fixing belt 1 to be fixed on a patient's limb. The fixing belt 1 is a prior art, that is, an existing compressor fixing belt 1. In this embodiment 1, the fixing belt 1 is used to be tied on the patient's arm 2;

[0038] Example 1 is basically as Figure 2-Figure 5 As shown, a medical hemostatic compressor comprises an inflatable pressing unit and a mechanical pressing unit, wherein the inflatable pressing unit is arranged at the center of the inflatable pressing unit;

[0039] like Figure 2 As shown, the mechanical pressing unit includes a sleeve 31 and a threaded rod 32. The threaded rod 32 includes a base section and an engagement section from top to bottom. The upper end of the base section is integrally formed with a terminal 38 for manual rotation. The base section passes through the sleeve 31 and is threadedly connected to the sleeve 31. A tightening piece 33 is welded at the lower end of the engagement section. The tightening piece 33 is an arc-shaped cover and is used to tighten the puncture point.

[0040] The inflatable pressing unit includes a shell 4, in which an inflatable chamber 41 and an air inlet chamber 42 are connected to each other. A one-way valve and a pressure valve (not shown in the figure) connected to the outside are provided on the side wall of the air inlet chamber 42. The one-way valve is used to inflate the air inlet chamber 42 from the outside, and the pressure valve is used to release the excess pressure in the pressure chamber. An inflatable assembly is provided in the air inlet chamber 42, and the inflatable assembly includes a sealing plate 43. A plurality of elastic members 46 are vertically adhered between the upper side of the sealing plate 43 and the air inlet chamber 42. The elastic member 46 is a spring. The sealing plate 43 separates the air inlet chamber 42 from top to bottom and seals the gap (the edge of the sealing plate 43 is sealed with rubber). The sealing plate 43 is used to press the gas in the air inlet chamber 42 into the inflatable chamber 41. Figure 4 As shown, the sealing plate 43 is integrally formed with two guide blocks 44 in an annular direction, and the side wall of the air inlet cavity 42 is provided with two vertical guide grooves 45, and the guide blocks 44 are respectively vertically slidably arranged in the guide grooves 45; four vertical racks 51 are circumferentially welded on the lower side of the sealing plate 43, and the lower ends of the vertical racks 51 are inserted into the bottom side of the air inlet cavity 42 and are slidably connected to the bottom side of the air inlet cavity 42.

[0041] like Figure 3 As shown, the inflation component also includes two first gears 52, two transmission shafts 53 and four second gears 54. The two sides of the meshing section are respectively meshed with the two first gears 52. The rotating shafts are all horizontally arranged, and the two ends are respectively connected to the center of the first gear 52 and the second gear 54. The radius of the second gear 54 is larger than the first gear 52. The second gears 54 are respectively meshed with the corresponding vertical racks 51. The rotating shaft is rotatably connected to the inner wall of the air inlet chamber 42. This is the prior art, and bearing support can be provided, which will not be repeated.

[0042] like Figure 2 As shown, the sleeve is arranged in the air inlet cavity 42, the upper end of the sleeve is welded to the upper side of the inner wall of the air inlet cavity 42, the lower end of the threaded rod 32 passes through the air inlet cavity 42 and enters the inflation cavity 41; the lower side of the inflation cavity 41 is provided with an air film 6, the inflation assembly is used to inflate the inflation cavity 41, the air film 6 bulges under the action of air pressure, and the air film 6 is used to press the position around the puncture point. A pressing block 34 is glued to the center of the lower side of the air film 6, and the adhesive material is a sealant. The lower side of the pressing piece 33 and the upper side of the pressing block 34 match in shape, and the contact surfaces are both arc-shaped surfaces. The pressing piece 33 presses against the pressing block 34 to press against the puncture point.

[0043] like Figure 5As shown, a sliding cavity 35 is vertically opened in the threaded rod 32, and the lower end of the sliding cavity 35 passes through the lower end of the threaded rod 32. The diameter of the opening at the lower end of the sliding cavity 35 is larger than the diameter of the rest of the part. A sliding rod 36 is welded on the upper side of the pressing block 34, and the upper end of the sliding rod 36 passes through the air film 6 and the fastening member 33 and is inserted into the sliding cavity 35. A limiting portion 37 is welded on the upper end of the sliding rod 36, and the limiting portion 37 and the sliding cavity 35 have a clearance fit, and the sliding rod 36 and the lower end opening of the sliding cavity 35 have a clearance fit, and the limiting portion 37 is used to limit the sliding rod 36 from sliding out of the sliding groove. The sliding rod 36 and the limiting portion 37 are both slidably connected to the sliding cavity 35, and the peripheral position of the sliding rod 36 on the upper surface of the pressing block 34 and the lower surface of the air film 6 are sealed with sealant, and an annular insulation gap is left between the periphery of the upper surface of the pressing block 34 and the air film 6.

[0044] When the lower end of the threaded rod 32 is pressed against the puncture point through the pressing block 34, the skin around the puncture point and the pressing block 34 is squeezed to form a raised skin, and the raised skin is accommodated in the thermal insulation gap between the pressing block 34 and the air film 6. The raised skin is stimulated by the pressing and tends to emit more heat, and due to the existence of the air film 6, this heat is retained in the thermal insulation gap; when the puncture point has basically stopped bleeding and the wound needs to be restored, a higher temperature is required to accelerate the healing of the wound; at this time, the threaded rod 32 rotates upward to reduce the pressing force, and the air film 6 bulges, gradually pushing the gas in the thermal insulation gap toward the puncture point, and the gas transfers the temperature to the transfer point, thereby accelerating the healing of the wound.

[0045] Example 2

[0046] Embodiment 2 is based on Embodiment 1: the shell 4 is made of transparent plastic material, and the air membrane 6 is made of transparent silicone material, so that medical staff can observe the puncture point at any time and take emergency measures.

[0047] Example 3

[0048] Example 3 is based on Example 1 or Example 2: it also includes an electrically connected blood detection unit and an alarm unit. The blood detection unit and the alarm unit are both existing technologies. The blood detection unit includes an electrically connected processor and a plurality of probes. The plurality of probes are distributed on the edge of the lower surface of the pressing fastener. The processor and the alarm unit are both installed on the outside of the shell 4. When the skin at the puncture point bleeds, the probe and the blood are short-circuited after contact, and the processor sends a signal to the alarm unit, which sounds an alarm to remind medical staff to come for inspection.
