Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a hemostatic device for medical care. Background Art

[0002] The hemostatic device includes a compression tourniquet. The compression tourniquet is generally used for rapid hemostasis after puncture surgery and accidents. By compressing the blood vessels near the wound, the blood flow in the blood vessels cannot flow to the wound, thus achieving the effect of rapid hemostasis. Although this form can achieve rapid hemostasis, the compression tourniquet will directly contact the wound. During the use of the compression tourniquet, it needs to be loosened regularly to enable the blood in the blood vessels to flow normally and prevent tissue necrosis due to ischemia. When the compression tourniquet is loosened, once the compression tourniquet shakes, it will cause the wound to be squeezed and rubbed, thereby affecting the wound healing speed. Therefore, the existing compression tourniquet has a poor hemostatic effect. Summary of the Invention

[0003] In order to overcome the shortcoming that the compression tourniquet directly squeezes and rubs the wound, the present invention provides a hemostatic device for medical care.

[0005] Further, the material of the edge of the fixing plate is flexible.

[0006] Further, it further includes: A sliding rod, which is hermetically slidably connected inside the telescopic part of the pressure regulator, the knob is used to squeeze the sliding rod to move, and a tension spring is fixedly connected between the telescopic part of the pressure regulator and the sliding rod; A shielding cover, which is arranged on the sliding rod, and the shielding cover is located inside the hole.

[0007] Further, the maximum diameter of the shielding cover is the same as the diameter of the hole.

[0008] Further, the compression pad is provided with two liquid sac parts distributed at intervals.

[0009] Further, the sliding rod is provided with a partition portion, a cavity is arranged inside the telescopic portion of the pressure regulator, the partition portion seals and slides inside the cavity, the partition portion divides the cavity inside the telescopic portion of the pressure regulator into a first chamber and a second chamber, and the first chamber and the second chamber are respectively communicated with different liquid sac portions.

[0010] Further, the knob is provided with a guiding groove, the sliding rod is provided with symmetrically distributed guiding surfaces, the guiding groove is used for squeezing the guiding surfaces so as to move the sliding rod, and the guiding groove is used for the sliding rod to slide therein.

[0011] Further, the gravity of the knob is greater than the force required for the tension spring on the sliding rod to be compressed.

[0012] Further, it further includes: A flexible ratchet ring, fixedly connected to the pressure regulator, the flexible ratchet ring is made of an elastic material; A wedge-shaped block, slidably connected to the fixing frame, a compression spring is fixedly connected between the wedge-shaped block and the fixing frame, and the flexible ratchet ring is used for squeezing the wedge-shaped block so as to move the wedge-shaped block.

[0013] Further, the elastic coefficient of the flexible ratchet ring is greater than the elastic coefficient of the compression spring between the wedge-shaped block and the fixing frame.

[0016] Compared with the prior art, the present invention has the following advantages: 1. The present invention covers the puncture wound through the holes, so that the patient's wound does not directly contact the pressing pad, thereby reducing the probability of the patient's wound being squeezed and rubbed by the pressing pad, and further ensuring the normal healing speed of the patient's wound and improving the hemostasis effect of the device; 2. By pressing the skin around the patient's wound with the shielding cover, when the pressing pad gradually compresses the blood vessels near the wound, the probability of the skin near the patient's wound being deformed due to the movement of the pressing pad is reduced, thereby reducing the probability of the wound rupturing due to the deformation of the skin at the wound, and protecting the skin at the patient's wound; 3.

By increasing the difficulty of the rotation of the flexible ratchet ring, when it is necessary to temporarily release the compression of the blood vessel by the compression pad, the resistance of the pressure regulator and the knob to rotate is increased, reducing the probability that the pressure regulator rotates suddenly, resulting in the sudden loss of the compression of the blood vessel by the compression pad, and further reducing the risk of sudden increase in blood flow in the blood vessel and reducing the possibility of the patient's wound scab being washed away by the blood flow; 6. By detachably connecting the shielding cover to the sliding rod, after the device is used, the shielding cover is replaced and the device is disinfected, so as to realize the reuse of the device and reduce the medical cost.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present invention will be further described below with reference to the drawings and embodiments.

[0020] A hemostatic device for medical care, such as Figures 1-5As shown in the figure, it includes: a fixing frame 1, the fixing frame 1 is fixedly connected with a fixing plate 101, the fixing plate 101 is used to support the fixing frame 1 to reduce the probability of the fixing plate 101 shaking. There is a hole for placing the knob 4 on the fixing plate 101, and the material of the edge of the fixing plate 101 is flexible to reduce the friction generated by the edge of the fixing plate 101 on the patient's skin. The fixing frame 1 is composed of an upper support plate, a middle strap and a lower flexible pad. When the fixing frame 1 is fixed on the patient, the length of the strap is adjusted to adapt to patients of different body types. The fixing frame 1 is rotatably connected to a pressure regulator 2. The pressure regulator 2 is a conventional structure and its principle is the same as that of a threaded sleeve. A limiting rod 201 is fixedly connected to the telescopic part of the pressure regulator 2, and the limiting rod 201 is slidably connected to the fixing frame 1 to limit the telescopic part of the pressure regulator 2 to prevent the telescopic part of the pressure regulator 2 from rotating. A pressing pad 3 is fixedly connected to the telescopic part of the pressure regulator 2. The pressing pad 3 is made of flexible material. The pressing pad 3 is used to press the blood vessels near the wound to reduce the bleeding amount of the wound. The pressing pad 3 is provided with a hole 301; a knob 4, which is slidably and rotatably connected to the fixing frame 1. The knob 4 can be detached from the fixing frame 1. The knob 4 is used to insert into the fixing part of the pressure regulator 2 to drive the fixing part of the pressure regulator 2 to rotate, so that the telescopic part of the pressure regulator 2 moves up and down.

[0021] As Figures 4-6 shown in the figure, it further includes: a sliding rod 5, which is hermetically and slidably connected inside the telescopic part of the pressure regulator 2. The knob 4 is used to squeeze the sliding rod 5 to move. A tension spring is fixedly connected between the telescopic part of the pressure regulator 2 and the sliding rod 5; a shielding cover 6, which is arranged on the sliding rod 5. The shielding cover 6 is located inside the hole 301. The shielding cover 6 is made of flexible material. The middle part of the lower side of the shielding cover 6 is recessed upward. The maximum diameter of the shielding cover 6 is the same as the diameter of the hole 301, so that the shielding cover 6 always fits the pressing pad 3 during the up and down movement. The shielding cover 6 shown in the figure is in a state of compressive deformation. After the pressing pad 3 fits the skin, the shielding cover 6 always contacts the skin.

[0022] When an operator needs to use this device to compress and stop bleeding at the puncture position of a patient, taking leg puncture as an example, the operator fixes the fixing frame 1 near the puncture position of the patient, makes the compression pad 3 located above the puncture wound, the hole 301 covers the puncture wound, the shielding cover 6 fits the patient's skin at this time, the edge of the fixing plate 101 deforms and fits the patient's skin, and then the operator presses down this device, so that the compression pad 3 presses the skin near the puncture wound. The operator withdraws the puncture needle. After the puncture needle is taken out, the operator installs the knob 4 on the fixing frame 1 and presses down the knob 4. The knob 4 squeezes the sliding rod 5 downward, and the tension spring of the sliding rod 5 stretches and stores energy. The sliding rod 5 drives the shielding cover 6 to move downward, the shielding cover 6 deforms, and the shielding cover 6 covers the puncture wound. The edge on the lower side of the shielding cover 6 presses the skin around the patient's wound. At this time, the operator rotates the knob 4, the knob 4 drives the pressure regulator 2 to rotate, the telescopic part of the pressure regulator 2 drives the compression pad 3 to move downward, and the compression pad 3 gradually compresses the blood vessels near the wound. Finally, the operator pulls out the knob 4, places the knob 4 in the hole position of the fixing plate 101, the tension spring of the sliding rod 5 rebounds and resets, the sliding rod 5 and the shielding cover 6 move back to their original positions, and the shielding cover 6 deforms and resets.

[0023] During the use by the patient, the hole 301 covers the puncture wound, so that the patient's wound does not directly contact the compression pad 3, thereby reducing the probability that the patient's wound is squeezed and rubbed by the compression pad 3, and then accelerating the healing speed of the patient's wound, improving the hemostatic effect of this device. And when the telescopic part of the pressure regulator 2 moves, making the compression pad 3 gradually compress the blood vessels near the wound, the edge on the lower side of the shielding cover 6 is used to press the skin around the patient's wound, so as to reduce the probability that the skin near the patient's wound is deformed due to the movement of the compression pad 3, thereby reducing the probability that the wound ruptures due to the deformation of the skin at the wound, and protecting the skin at the patient's wound.

[0024] When the operator needs to temporarily release the compression of the blood vessel by the compression pad 3 (in order to prevent the patient's tissue from necrosis due to ischemia, usually release it once every 30 minutes to 1 hour, and each release lasts for 1 - 2 minutes), the operator installs the knob 4 on the fixing frame 1 again. The knob 4 presses the sliding rod 5 by its own gravity, and the tension spring of the sliding rod 5 is stretched and stores energy. The sliding rod 5 drives the shielding cover 6 to move downward, and the shielding cover 6 covers the puncture wound. The lower edge of the shielding cover 6 presses the skin around the patient's wound, and the shielding cover 6 deforms. At this time, the operator rotates the knob 4 in the reverse direction, and the knob 4 drives the fixed part of the pressure regulator 2 to rotate in the reverse direction. The telescopic part of the pressure regulator 2 drives the compression pad 3 to move upward, and the compression pad 3 gradually releases the compression on the blood vessel near the wound. At this time, the shielding cover 6 covers the wound. After the compression pad 3 is released, if the wound bleeds, the shielding cover 6 seals the wound to reduce the blood outflow from the wound. When the blood in the blood vessel circulates normally, the operator repeats the above steps to rotate the knob 4, so that the telescopic part of the pressure regulator 2 drives the compression pad 3 to move downward and compress the blood vessel again. By repeating the above steps continuously, the compression on the blood vessel is released regularly to prevent tissue ischemia necrosis.

[0025] After the use of this device, when the patient's wound heals, the operator removes the fixing frame 1 and disinfects and processes this device.

[0026] As Figures 3-5 shown, the compression pad 3 is provided with two liquid sac parts 7 distributed at intervals, and the middle part of the lower side surface of the liquid sac part 7 is recessed upward.

[0027] As Figures 4-6 shown, the sliding rod 5 is provided with a partition part 8, and a cavity is arranged in the telescopic part of the pressure regulator 2. The partition part 8 seals and slides in this cavity. The partition part 8 divides the cavity in the upper telescopic part of the pressure regulator 2 into a first chamber 801 and a second chamber 802. Liquids are arranged in both the first chamber 801 and the second chamber 802. The first chamber 801 and the second chamber 802 are respectively communicated with different liquid sac parts 7. The partition part 8 moves up and down to alternately discharge the liquids in the first chamber 801 and the second chamber 802, so that the two liquid sac parts 7 are alternately deformed.

[0028] As Figure 6 As Figure 7 shown, the knob 4 is provided with a guide groove 9, and the sliding rod 5 is provided with guide surfaces 10 symmetrically distributed front and back. During the rotation of the knob 4, the knob 4 drives the guide groove 9 to rotate. The guide surface 10 first inserts into the guide groove 9, and then the guide groove 9 squeezes the guide surface 10 to make the sliding rod 5 move back to its original position. In this way, the sliding rod 5 moves up and down reciprocally. The guide groove 9 is used for the sliding rod 5 to slide therein, and the gravity of the knob 4 is greater than the force required for the tension spring on the sliding rod 5 to be compressed.

[0029] When the operator needs to temporarily release the compression of the compression pad 3 on the blood vessel, the operator rotates the knob 4. The knob 4 drives the guide groove 9 to rotate, so that the guide surface 10 is inserted into the guide groove 9. The tension spring of the sliding rod 5 rebounds, causing the sliding rod 5 to move upward. Then the guide groove 9 rotates and presses the guide surface 10, causing the guide surface 10 to be pressed downward and the sliding rod 5 to move downward. The tension spring of the sliding rod 5 is stretched. Along with the rotation of the guide groove 9, the sliding rod 5 moves up and down reciprocally (when the sliding rod 5 moves downward, the shielding cover 6 is deformed under pressure and adheres tightly to the patient's skin. When the sliding rod 5 moves upward, the shielding cover 6 is no longer deformed but still adheres tightly to the patient's skin). The tension spring of the sliding rod 5 deforms reciprocally. The sliding rod 5 drives the partition part 8 to move up and down. Taking the partition part 8 moving upward first as an example, the partition part 8 squeezes the liquid in the first chamber 801 into the right liquid sac part 7, and the liquid in the left liquid sac part 7 is drawn into the second chamber 802. Then the partition part 8 moves downward, and the partition part 8 squeezes the liquid in the second chamber 802 into the left liquid sac part 7, and the liquid in the right liquid sac part 7 is drawn into the first chamber 801. By repeating the above steps, the two liquid sac parts 7 expand alternately, pressing on the blood vessel. While promoting blood flow in the blood vessel, the wound is covered by the shielding cover 6, reducing the probability of excessive bleeding from the wound after the blood vessel compression disappears.

[0030] As Figure 2 、 Figure 5 shown in Figure 6 Figure, it further includes: a flexible ratchet ring 11, fixedly connected to the pressure regulator 2. The flexible ratchet ring 11 is made of an elastic material and is provided with a plurality of first inclined surfaces and a plurality of first vertical surfaces; a wedge block 12, slidably connected to the fixed frame 1. The wedge block 12 is provided with a second inclined surface and a second vertical surface. Taking Figure 1 the top view as the rotation reference, during the process of the pressure regulator 2 driving the flexible ratchet ring 11 to rotate clockwise, all the first inclined surfaces of the flexible ratchet ring 11 sequentially press the second inclined surface of the wedge block 12, causing the wedge block 12 to move back and forth continuously. The compression spring of the wedge block 12 deforms continuously. During the process of the pressure regulator 2 driving the flexible ratchet ring 11 to rotate counterclockwise, the flexible ratchet ring 11 presses the wedge block 12, the flexible ratchet ring 11 deforms, and the resistance to the rotation of the flexible ratchet ring 11 increases. A compression spring is fixedly connected between the wedge block 12 and the fixed frame 1. The flexible ratchet ring 11 is used to press the wedge block 12 to make the wedge block 12 move. The elastic coefficient of the flexible ratchet ring 11 is greater than the elastic coefficient of the compression spring between the wedge block 12 and the fixed frame 1.

[0031] When the operator rotates the knob 4 clockwise (the rotation direction is based on Figure 1(with the top view as the reference), the knob 4 drives the pressure regulator 2 to rotate clockwise. The telescopic part of the pressure regulator 2 extends out. The pressure regulator 2 drives the flexible ratchet ring 11 to rotate clockwise. The flexible ratchet ring 11 squeezes the second inclined surface of the wedge block 12 through the first inclined surface, causing the wedge block 12 to move. The compression spring of the wedge block 12 is compressed. After the first inclined surface of the flexible ratchet ring 11 loses contact with the wedge block 12, the compression spring of the wedge block 12 resets, causing the wedge block 12 to move back to its original position. When it is necessary to temporarily release the compression of the blood vessel by the compression pad 3, the operator rotates the knob 4 counterclockwise. The knob 4 drives the pressure regulator 2 to rotate counterclockwise. The pressure regulator 2 drives the flexible ratchet ring 11 to rotate counterclockwise. The first vertical surface of the flexible ratchet ring 11 directly squeezes the second vertical surface of the wedge block 12. If the flexible ratchet ring 11 wants to rotate, the flexible ratchet ring 11 needs to deform, increasing the resistance to the rotation of the flexible ratchet ring 11 and the difficulty of rotating the flexible ratchet ring 11. Thus, the resistance to the counterclockwise rotation of the pressure regulator 2 and the knob 4 increases, increasing the difficulty of the counterclockwise rotation of the pressure regulator 2 and the knob 4, reducing the probability that the pressure regulator 2 rotates counterclockwise suddenly, resulting in the compression pad 3 suddenly losing the compression of the blood vessel, and further reducing the risk of a sudden increase in blood flow in the blood vessel and the possibility of the patient's wound scab being washed away by the blood flow.

[0032] As Figure 4 shown in Figure 5 Figure, a number of ventilation slots 13 are provided on the upper side of the compression pad 3. The ventilation slots 13 communicate with the holes 301. The shielding cover 6 is detachably connected to the sliding rod 5. Drugs are provided on the lower side of the shielding cover 6, and the drugs can be hemostatic powder.

[0033] During the use of this device, the skin near the patient's wound is ventilated with the external environment through the ventilation slots 13, increasing the somatic comfort of the skin near the patient's wound. And the hemostatic drugs on the shielding cover 6 come into contact with and fit the wound and blood, promoting blood coagulation to enhance the hemostatic effect of this device.

[0034] After the use of this device, when the patient's wound heals, the operator removes the fixing frame 1, disinfects this device, and then removes the shielding cover 6 and replaces the shielding cover 6, thus realizing the reuse of this device and reducing the medical cost.

[0035] In summary, the above is only the preferred embodiment of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
