Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and more particularly to an emergency care hemostasis auxiliary device. Background Art

[0002] Hemostasis in emergency care is a key step in dealing with bleeding situations. It aims to control bleeding as quickly as possible to reduce blood loss, prevent shock, and create conditions for subsequent treatment. In emergency care, correct and rapid hemostasis is crucial. For minor epidermal wounds or bleeding in a small area, direct pressure with a clean bandage or gauze is the most basic and most commonly used method of hemostasis. Small to medium-sized open wounds that are difficult to control with physical pressure require the use of hemostatic powders, gels and other hemostatic drugs to promote rapid blood coagulation, thereby achieving a hemostatic effect. When necessary, a tourniquet is also needed to temporarily block blood flow to achieve the purpose of hemostasis.

[0003] Common methods of stopping bleeding in emergency: direct compression method uses clean cloth, gauze or bandage to press directly on the wound, maintain pressure until the bleeding stops. If the blood soaks through the first layer of dressing, do not remove it, but add a new layer of dressing on it to continue to apply pressure. Pressure bandage method: After placing a clean dressing on the wound, wrap it tightly with a bandage to provide continuous pressure. Tourniquet is used as a last resort when severe bleeding in the limbs cannot be controlled by other means. It should be placed a few centimeters proximal to the wound.

[0004] In actual use of the existing technology, medical staff need to go through multiple steps when performing hemostatic bandage on patients, such as applying medicine, covering with gauze, fixing bandages, etc. Each step takes time, which is slow and time-consuming in emergency situations. Therefore, in response to the above technical problems, it is necessary to provide an emergency care hemostatic auxiliary device. Summary of the invention

[0005] The purpose of the present invention is to provide an emergency care hemostasis auxiliary device to solve the above-mentioned problems.

[0006] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0007] An emergency care hemostasis auxiliary device comprises a dressing table, a positioning component and a hemostasis component, comprising a storage box fixedly connected above a rectangular protruding part of the dressing table, a box cover hinged on the upper surface of the storage box, comprising two positioning frames symmetrically fixedly connected to the upper surface of the dressing table, a groove is opened in the inner cavity of the positioning frame, a tourniquet is connected to the bottom position of the inner cavity of the groove by shaft rotation, a plurality of positioning holes are opened on the outer surface of the tourniquet, two spherical positioning rods are symmetrically fixedly connected to the upper surface of the dressing table, comprising a wrapping sticker located in the storage box, an arc-shaped pressing plate is fixedly connected to the middle position of the lower surface of the wrapping sticker, an isolation layer is fixedly connected to the lower surface of the arc-shaped pressing plate, a hole is opened in the middle position of the isolation layer and a thin film is fixedly connected, an anti-permeability layer is fixedly connected to the lower surface of the isolation layer, a hemostatic cotton is fixedly connected to the inner cavity of the anti-permeability layer, a silicone base is inlaid and fixedly connected to the middle position of the upper surface of the hemostatic cotton, and a microneedle is inlaid and fixedly connected to the inner cavity of the silicone base.

[0008] As a further improvement of the present invention, the storage box and the box cover are made of transparent material, a round hole is opened on the positioning frame, and the groove is opened on the inner wall of the round hole on the positioning frame.

[0009] As a further improvement of the present invention, the spherical positioning rod is located on the side of the positioning frame and is located on the same horizontal line as the tourniquet, and the outer surface of the spherical positioning rod is movably connected to the positioning hole.

[0010] As a further improvement of the present invention, the tourniquet is made of silicone material, and the tourniquet is movably placed inside the groove and moves in the groove.

[0011] As a further improvement of the present invention, a release paper is adhered to the lower surface of the wrapping patch by glue, and the release paper isolates the anti-permeability layer and the lower surface of the hemostatic cotton from the external environment.

[0012] As a further improvement of the present invention, the isolation paper is made of a transparent material, and the contact surface of the wrapping sticker with the external environment is provided with a protective layer made of a polyethylene material.

[0013] As a further improvement of the present invention, the arc-shaped pressing plate is made of elastic rubber material, and the upper surface of the arc-shaped pressing plate is connected to an air intake pipe.

[0014] As a further improvement of the present invention, a check valve is installed on the air intake pipe, and the air intake pipe controls the gas through the check valve so that the gas can only be input into the arc-shaped pressing plate through the air intake pipe.

[0015] As a further improvement of the present invention, a closed drug storage cavity is formed between the arc-shaped pressing plate and the isolation layer for storing hemostatic drugs, and a flow cavity is formed between the isolation layer and the hemostatic cotton.

[0016] As a further improvement of the present invention, the isolation layer is a plastic isolation cloth made of polyethylene material, and the film is made of elastic rubber material.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] This solution works by extending the part of the patient that needs hemostasis, such as the arm, into two positioning frames, and placing the part that needs hemostasis between the two positioning frames. The tourniquet is then pulled outward to tighten the tourniquet in the groove to slightly bind the patient's arm, and the position of the tourniquet is fixed by inserting a ball-shaped positioning rod into the positioning hole to prevent the patient from moving around due to pain during the hemostatic bandage. This ensures that the patient's arm remains stable during the hemostasis process and reduces operational difficulties caused by the patient's movement.

[0019] In this solution, when the patient is bleeding heavily, the tourniquet on the side close to the patient's heart is used as a first aid tool to temporarily control severe bleeding in the limbs. The tourniquet is pulled outward and tightly wrapped around the patient's arm. The tourniquet is tightened to compress the patient's limbs to block blood flow, effectively controlling the patient's severe bleeding and buying precious time for subsequent professional medical treatment. The tourniquet can be used as a binding tool as well as a first aid tool for stopping bleeding. The operator can choose the usage method according to the actual situation to meet different needs.

[0020] In this solution, the wrapping patch is pasted on the patient's skin by tearing off the isolation paper, absorbing blood through the hemostatic cotton to help stop bleeding, and preventing blood from penetrating outward through the anti-permeation layer. Then, the arc-shaped pressing plate is pressed downward to squeeze the gas and hemostatic drug in the closed drug storage cavity formed between the arc-shaped pressing plate and the isolation layer. The gas pushes the film to extend downward and the protrusion is punctured when it contacts the microneedle. At this time, the gas drives the hemostatic drug to flow through the hole into the circulation cavity, and penetrates the hemostatic drug into the wound through the penetration holes on the hemostatic cotton, helping to stop bleeding quickly. The isolation layer can prevent the hemostatic drug from flowing back. Medical staff or patients can manually press the arc-shaped pressing plate multiple times to blow the gas through the hole to the circulation cavity, and blow the hemostatic drug to the patient's injured area multiple times. The operation is simple, fast, and gentle. Blowing gas to the patient's injured area can relieve the stuffiness and discomfort of the wound. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] See also Figure 1-2 An emergency care hemostasis auxiliary device includes a dressing table 1, a positioning component 2 and a hemostasis component 3, including a storage box 101 fixedly connected above a rectangular raised portion of the dressing table 1, a box cover 102 hinged on the upper surface of the storage box 101, including two positioning frames 201 symmetrically fixedly connected to the upper surface of the dressing table 1, a groove 202 is opened in the inner cavity of the positioning frame 201, a tourniquet 203 is connected to the bottom position of the inner cavity of the groove 202 through an axis rotation, a plurality of positioning holes 204 are opened on the outer surface of the tourniquet 203, and two spherical positioning rods 205 are symmetrically fixedly connected to the upper surface of the dressing table 1.

[0031] Specifically, the storage box 101 and the box cover 102 are made of transparent material, a round hole is opened on the positioning frame 201, and the groove 202 is opened on the inner wall of the round hole on the positioning frame 201. The spherical positioning rod 205 is located on the side of the positioning frame 201 and is located on the same horizontal line as the tourniquet 203. The outer surface of the spherical positioning rod 205 is movably connected with the positioning hole 204. The tourniquet 203 is made of silicone material. The tourniquet 203 is movably placed inside the groove 202 and moves inside the groove 202.

[0032] Furthermore, the dressing table 1 provides a stable working platform for medical personnel to perform hemostatic operations, the storage box 101 is used to store hemostatic supplies, and the box cover 102 is used to protect the items in the storage box 101 and keep them clean. The storage box 101 and the box cover 102 are both made of transparent materials, which is convenient for medical personnel to promptly understand the usage of the internal hemostatic supplies and to facilitate timely replenishment.

[0033] The medical staff inserts the part of the patient that needs to stop bleeding, such as the arm, into the two positioning frames 201, and places the part that needs to stop bleeding between the two positioning frames 201, and then pulls the tourniquet 203 outward to tighten the tourniquet 203 in the groove 202 to slightly bind the patient's arm, and fixes the position of the tourniquet 203 by inserting the ball-shaped positioning rod 205 into the positioning hole 204 to prevent the patient from moving around due to pain during the hemostatic bandage, ensure stability during hemostasis, and help medical staff to perform hemostasis operations more quickly. At this time, the tourniquet 203 is only used as a binding tool to restrict the patient's movements.

[0034] When the patient is bleeding heavily, the tourniquet 203 near the patient's heart can be used as an emergency tool to temporarily control severe bleeding in the limbs. The tourniquet 203 is pulled outward to wrap it tightly around the patient's arm, and the blood flow is blocked by tightening the tourniquet 203 to compress the patient's limbs. Note that the tourniquet 203 should be loosened for 1-2 minutes every 15-20 minutes when used, and the tourniquet should not be used for a long time to avoid tissue ischemia and necrosis.

[0035] Embodiment 2:

[0036] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 An emergency care hemostasis auxiliary device includes a wrapping patch 301 located in a storage box 101, wherein an arc-shaped pressing plate 303 is fixedly connected to the middle position of the lower surface of the wrapping patch 301, an isolation layer 304 is fixedly connected to the lower surface of the arc-shaped pressing plate 303, a hole 305 is opened in the middle position of the isolation layer 304 and a film 306 is fixedly connected to it, an anti-permeation layer 311 is fixedly connected to the lower surface of the isolation layer 304, a hemostatic cotton 309 is fixedly connected to the inner cavity of the anti-permeation layer 311, a silicone base 313 is inlaid and fixedly connected to the middle position of the upper surface of the hemostatic cotton 309, and a microneedle 314 is inlaid and fixedly connected to the inner cavity of the silicone base 313.

[0037] Specifically, the lower surface of the wrapping patch 301 is adhered with a release paper 302 by glue, and the release paper 302 isolates the lower surface of the anti-permeation layer 311 and the hemostatic cotton 309 from the external environment. The release paper 302 is made of a transparent material, and the contact surface of the wrapping patch 301 with the external environment is provided with a protective layer made of a polyethylene material. The arc-shaped pressing plate 303 is made of an elastic rubber material, and the upper surface of the arc-shaped pressing plate 303 is connected to the air inlet pipe 307, and a check valve 308 is installed on the air inlet pipe 307. The air inlet pipe 307 controls the gas through the check valve 308 so that the gas can only pass through the air inlet pipe 307. 07 is input into the arc-shaped pressing plate 303, and a closed drug storage chamber is formed between the arc-shaped pressing plate 303 and the isolation layer 304 for storing hemostatic drugs. The hemostatic drugs in this scheme can have two forms, which can be solid hemostatic drug powder or liquid hemostatic drug solution, both of which can flow in the device for hemostatic operation, and can be selected according to actual conditions and needs. A flow cavity 312 is formed between the hemostatic isolation layer 304 and the hemostatic cotton 309. The isolation layer 304 is a plastic isolation cloth made of polyethylene material, and the film 306 is made of elastic rubber material.

[0038] Further, open the box cover 102 to take out the wrapping patch 301 in the storage box 101, and tear off the isolation paper 302 under the wrapping patch 301. The isolation paper 302 is used to protect the hemostatic cotton 309 under the wrapping patch 301 to prevent it from contacting the external environment and needs to be torn off before use.

[0039] Aim the hemostatic cotton 309 at the bleeding site of the patient, and then stick the wrapping patch 301 on the patient's skin. The glue on the wrapping patch 301 is a safe glue that can come into contact with the skin. The hemostatic cotton 309 absorbs blood to help stop bleeding. The anti-permeability layer 311 is located on the outer layer of the hemostatic cotton 309 to prevent blood from penetrating outward.

[0040] Then, by pressing the arc-shaped pressing plate 303 downward, the gas and hemostatic drugs in the closed drug storage cavity are squeezed between the arc-shaped pressing plate 303 and the isolation layer 304, and the gas pushes the film 306 to extend and bulge downward (similar to the principle of blowing a balloon). When the film 306 extends downward and contacts the microneedle 314, it is punctured. At this time, the film 306 is damaged and rebounds and shrinks to leak out the cavity 305. The cavity 305 serves as a gas channel, allowing gas to pass through. The film 306 is made of elastic rubber material, has the characteristics of high elasticity and good ductility, can be squeezed and bulged by gas, is easy to puncture, and will shrink after puncture (you can refer to the material of the inflated balloon, but it is thinner than the inflated balloon and easier to puncture). At this time, the gas drives the hemostatic drug to flow through the cavity 305 into the circulation cavity 312, and penetrates the hemostatic drug into the wound through the penetration hole 310 on the hemostatic cotton 309, which helps to stop bleeding quickly. The isolation layer 304 can prevent the hemostatic drug from flowing back.

[0041] The arc-shaped pressing plate 303 is made of elastic rubber material and can automatically rebound after being pressed. At this time, air can be introduced into the drug storage chamber again through the air inlet pipe 307, and the check valve 308 can prevent the gas from flowing outward. Medical staff or patients can manually press the arc-shaped pressing plate 303 multiple times to blow the gas through the hole 305 to the circulation cavity 312. The circulation cavity 312 serves as a space for mixing gas and medicine to ensure that the medicine is evenly distributed. The hemostatic medicine is blown to the patient's wound multiple times, and the gentle gas blowing to the patient's wound can relieve the stuffiness and discomfort of the wound. The silicone base 313 provides soft and stable support for the microneedle 314 to ensure that the microneedle 314 can stand upright without falling down, and is not too hard to affect the comfort during use. The microneedle 314 is set upward to avoid piercing the patient's wound.

[0042] Working principle: During the use of the device, the medical staff inserts the part of the patient that needs to stop bleeding, such as the arm, into the two positioning frames 201, and places the part that needs to stop bleeding between the two positioning frames 201, and then pulls the tourniquet 203 outward to tighten the tourniquet 203 in the groove 202 to slightly bind the patient's arm, and inserts the ball-shaped positioning rod 205 into the positioning hole 204 to fix the position of the tourniquet 203 to prevent the patient from moving around due to pain during the hemostatic bandage. At this time, the tourniquet 203 is only used as a binding tool to restrict the patient's movement. When the patient's bleeding is more, the tourniquet 203 close to the patient's heart side can be used as a first aid tool to temporarily control severe bleeding in the limbs. The tourniquet 203 is pulled outward to wrap it tightly around the patient's arm, and the tourniquet 203 is tightened to compress the patient's limbs to block the blood flow. Then the box cover 102 is opened to take out the wrapping patch 301 in the storage box 101, and the bottom of the wrapping patch 301 is torn off The wrapping patch 301 is then pasted on the patient's skin, the hemostatic cotton 309 absorbs blood, and the anti-permeation layer 311 prevents blood from penetrating outwards. Then, the arc-shaped pressing plate 303 is pressed downward to squeeze the gas and hemostatic drug in the closed drug storage cavity formed between the arc-shaped pressing plate 303 and the isolation layer 304. The gas pushes the film 306 to extend downward. When the protrusion contacts the microneedle 314, it is punctured. At this time, the gas drives the hemostatic drug to flow into the circulation cavity 312 through the hole 305. The arc-shaped pressing plate 303 can automatically rebound after being pressed and let air flow into the drug storage cavity again through the air inlet pipe 307. The check valve 308 can prevent the gas from flowing outward. Medical staff or patients can manually press the arc-shaped pressing plate 303 multiple times to blow the gas through the hole 305 to the circulation cavity 312, and blow the hemostatic drug to the patient's wound multiple times.
