Description

Technical Field

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

[0002] The human body may develop a variety of tumors in its limbs, the most common of which include osteosarcoma, soft tissue sarcoma, giant cell tumor of bone, etc. These tumors can invade the surrounding blood vessels and tissues, causing blood vessel rupture and bleeding. At the same time, because the wounds are invaded by tumors, the body's hematopoietic function is reduced. While physically stopping bleeding, its coagulation function must also be improved.

[0003] The traditional method of stopping bleeding is to only squeeze the cotton ball with gauze strips to stop bleeding. This method is not only inefficient, but also has disadvantages such as incomplete hemostasis, inconvenient operation, and difficult pressure control and observation. It can also easily cause severe pain or tissue damage.

[0004] In order to solve the above technical problems, Chinese patent document CN108030529B discloses a rapid hemostasis device with an airbag, which is configured by inserting one end of the connecting tube connected to the airbag into the wound tract until the top of the wound tract, and then inserting the other end of the connecting tube into the channel from the top of the hemostasis unit. The hemostasis unit is inserted into the wound tract along the guidance of the connecting tube, and the next hemostasis unit is inserted into the wound tract in the same way, and its top is inserted into the recessed part of the previous hemostasis unit. Multiple hemostasis units are inserted in the above manner until the first hemostasis unit inserted into the wound tract reaches the top of the wound tract. Then, the wound surface is appropriately blocked and fixed, such as simply binding with a bandage, sticking the wound surface with medical tape, etc., which is simple and efficient.

[0005] However, the above-mentioned devices are relatively complex as a whole, and their applicable scenarios are relatively one-sided. In addition, each hemostatic device must be accompanied by a separate inflation device, which may cause the device to be larger in size, inconvenient to carry, or a small number of devices that can be carried at a time.

[0006] Therefore, inventors in the field have proposed a compression hemostasis device for oncology nursing to solve the above problems. Summary of the invention

[0007] Technical problems to be solved: The device as a whole is relatively complex, and its applicable scenarios are relatively one-sided. In addition, each hemostatic device must be equipped with a separate inflation device, which may cause the device to be larger in size, inconvenient to carry, or a small number of devices can be carried at a time.

[0008] In view of the deficiencies in the prior art, the present invention provides a compression hemostasis device for oncology internal medicine nursing, thereby solving the technical problems mentioned in the background technology.

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0010] A compression hemostasis device for oncology nursing, comprising a drug hemostasis component, a compression hemostasis component, and an air pump, wherein the drug hemostasis component comprises a tourniquet, the outside of the tourniquet is fixedly connected with a binding strap, the inside of the tourniquet is provided with a hemostatic drug layer, and the outside of the hemostatic drug layer is wrapped with a water-soluble layer;

[0011] The compression hemostasis component comprises a tying airbag and a compression airbag, and both the tying airbag and the compression airbag are arranged inside the tourniquet.

[0012] In a possible implementation, a Velcro velvet surface is fixedly connected to one end of the strap close to the tourniquet, and a Velcro spiky surface is fixedly connected to one end of the strap opposite to the Velcro velvet surface.

[0013] In a possible implementation, the water-soluble layer melts after contacting blood, and the water-soluble layer is made of chitosan material.

[0014] In a possible implementation, the binding airbag is strip-shaped, and the compression airbag is spherical.

[0015] In one possible implementation, the outside of the binding airbag and the compression airbag are connected to an air nozzle through a connecting tube, an air passage is opened inside the air nozzle, an air-blocking plate is slidably connected between the air passages, a spring is arranged between the inner wall of the air nozzle and the air-blocking plate, the air-blocking plate is tightly fitted to the inner wall of the air nozzle, a limiting plate is fixedly connected to the opening of the air nozzle, and a slot is opened on one side of the two limiting plates close to the inside of the air nozzle.

[0016] In a possible implementation, in order to distinguish the two air nozzles, the outside of the air nozzle connected to the binding airbag is red, and the outside of the air nozzle connected to the compression airbag is blue.

[0017] In a possible implementation, the air outlet of the air pump is provided with a plug 1, and the outside of the plug 1 is also fixedly connected to two limit plates 2, and the two limit plates 2 are fixedly connected to one side close to the air pump with a card.

[0018] In a possible implementation, the first limiting plate and the second limiting plate are both designed in a quarter-circular ring shape, and the first limiting plate and the second limiting plate are staggered in pairs to form a circular ring shape.

[0019] In a possible implementation, one end of the air pump away from the first insertion tube is fixedly connected to the second insertion tube, and the second insertion tube is provided with a plurality of exhaust grooves.

[0020] Beneficial effects compared with the prior art:

[0021] 1. In this scheme, the patient's limbs can be tied up by a tourniquet and a bandage. When blood penetrates, the water-soluble layer is ablated to allow the hemostatic drug layer to penetrate, and the coagulation power of the hemostatic drug layer is utilized to accelerate the coagulation function of the blood in the affected area;

[0022] 2. In this scheme, air is injected into the binding airbag through an air pump and related components. Since the binding airbag is bound in a ring shape on the limb, when the binding airbag is filled with gas, the binding airbag surrounding the limb squeezes the limb through the squeezing force of expansion, blocks the circulation of blood vessels, and then avoids the penetration of venom;

[0023] 3. In this scheme, air is injected into the interior of the compression bag through an air pump and related components. Since the compression bag is spherical and is located on the upper side of the limb bleeding point close to the heart, the compression bag expands and squeezes the blood vessels to stop continuous bleeding. At the same time, the coagulation power of the hemostatic drug layer is used to accelerate coagulation, thereby achieving a dual hemostatic effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can be implemented in various forms, so the present invention is not limited to the embodiments described below. In addition, in order to more clearly describe the present invention, components that are not connected with the invention will be omitted from the drawings.

[0035] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0036] Example:

[0037] Please refer to Figure 1 and Figure 8 As shown, this embodiment introduces a specific structure of a compression hemostasis device for oncology nursing, including a drug hemostasis component, a compression hemostasis component, and an air pump 16;

[0038] The drug hemostasis component is used for drug-assisted treatment of bleeding points on the patient's limbs, including disinfection through drugs and acceleration of wound clotting time through drugs, as follows:

[0039] The drug hemostasis component comprises a tourniquet 1, the outside of the tourniquet 1 is fixedly connected with a binding strap 2, a side of the binding strap 2 close to the tourniquet 1 is fixedly connected with a Velcro velvet surface 3, and a side of the binding strap 2 opposite to the Velcro velvet surface 3 is fixedly connected with a Velcro thorn surface 4. When a bleeding point appears on a patient's limb, the tourniquet 1 is firstly tied to the limb where the bleeding point is located, and then the binding strap 2 is tied again in the opposite direction to the binding direction of the tourniquet 1, and then the tourniquet 1 is fixed to the patient's limb by using the binding strap 2 through the Velcro velvet surface 3 and the Velcro thorn surface 4;

[0040] The interior of the tourniquet 1 is provided with a hemostatic drug layer 5, and the exterior of the hemostatic drug layer 5 is wrapped with a water-soluble layer 6. When a patient's limb is bleeding a small amount, the tourniquet 1 and the bandage 2 can be tied together, and then the blood penetrates into the interior of the tourniquet 1. When the water-soluble layer 6 contacts the blood, the water-soluble layer 6 will gradually melt. Then, the hemostatic drug layer 5, without the restriction of the water-soluble layer 6, begins to penetrate and gradually penetrates into the wound. On the one hand, the blood coagulation function of the wound is increased by the drug effect, and on the other hand, the wound is disinfected.

[0041] The compression hemostasis component is used in two situations. One is when the patient's limbs are bitten by a venomous snake, and the other is when the patient's limbs are bleeding heavily. In this case, it can be combined with a drug hemostasis component to achieve better results. The details are as follows:

[0042] The compression hemostasis component includes a binding airbag 7 and a compression airbag 8. Both the binding airbag 7 and the compression airbag 8 are arranged inside the tourniquet 1. The binding airbag 7 is in a strip shape. When the tourniquet 1 is tied to the patient's limbs, the binding airbag 7 can be tied to the patient's limbs at the same time as the tourniquet 1. The binding airbag 7 forms a circle on the limbs. This design allows the device to be used not only for hemostasis in oncology, but also for field nursing. For example, when the binding airbag 7 is used for patients bitten by venomous snakes in the field, the tourniquet 1 is tied above the venomous snake bite site to prevent the spread of venom. By inputting gas into the binding airbag 7, the inflated binding airbag 7 applies annular pressure around the limbs, thereby blocking the infiltration of venom for a short time, so as to buy time for treatment.

[0043] The compression airbag 8 is spherical in design. When the patient's limbs bleed a lot, before tying the tourniquet 1 on the limbs, first move the compression airbag 8 to the upper side of the bleeding point close to the human heart, and then firmly tie the tourniquet 1 to the limbs through the strap 2. Then, by injecting gas into the compression airbag 8, the compression airbag 8 expands and squeezes the blood vessels, thereby reducing bleeding. At the same time, blood penetrates into the tourniquet 1, and the water-soluble layer 6 melts after contacting the blood. The water-soluble layer 6 is made of chitosan material. Then the hemostatic drug layer 5 begins to penetrate, exerting its drug effect of coagulation and disinfection, and forming a dual effect with the compression airbag 8, thereby further improving the hemostatic efficiency.

[0044] The outside of the tying airbag 7 and the compression airbag 8 are both connected to an air nozzle 10 through a connecting tube 9. To distinguish the two air nozzles 10, the outside of the air nozzle 10 connected to the tying airbag 7 is red, and the outside of the air nozzle 10 connected to the compression airbag 8 is blue. An air passage 11 is provided inside the air nozzle 10, and an air-blocking plate 12 is slidably connected between the air passage 11. A spring 13 is provided between the inner wall of the air nozzle 10 and the air-blocking plate 12. The air-blocking plate 12 is pushed to move by the rebound force of the spring 13, and the air passage 11 is closed by the air-blocking plate 12. The air-blocking plate 12 fits tightly with the inner wall of the air nozzle 10.

[0045] The air outlet of the air pump 16 is provided with a plug 17, which is inserted into the interior of the air nozzle 10 through the plug 17 to squeeze the air-closing plate 12 and move it toward the interior of the air nozzle 10. The exterior of the plug 17 is also fixedly connected to two quarter-circular limiting plates 18. The quarter-circular limiting plates 14 and the two quarter-circular limiting plates 18 are staggered in pairs to form a circle. The two limiting plates 18 are fixedly connected to a card bead 19 on one side close to the air pump 16. When the plug 17 is fully inserted into the interior of the air nozzle 10, it is slightly rotated to inflate the air. The air pump 16, under the action of the rebound force of the spring 13, the air-blocking plate 12 pushes the insert tube 17 to move outward, and the insert tube 17 drives the card bead 19 to connect with the limiting plate 14 near the inside of the air nozzle 10. When the air pump 16 is continuously rotated, the two card slots 15 overlap with the positions of the two card beads 19 respectively, and then the two card slots 15 are respectively engaged with the two card beads 19 under the push of the spring 13, and then the insert tube 17 is connected to the air nozzle 10, and then the air pump 16 is continuously inflated to inject gas into the inside of the tying airbag 7 or the compression airbag 8;

[0046] After the gas is fully inflated, the insert tube 17 is pushed again, and the insert tube 17 pushes the air-blocking plate 12 to move toward the inside of the air nozzle 10. At the same time, the limit plate 14 is separated from the limit plate 2 18, and the card slot 15 is separated from the card bead 19. Then the insert tube 17 is rotated to interlace the limit plate 2 18 with the limit plate 14, and then the insert tube 17 is moved out of the inside of the air nozzle 10. The spring 13 rebounds and pushes the air-blocking plate 12, and the airway 11 is closed through the air-blocking plate 12 to prevent the gas inside the binding airbag 7 and the compression airbag 8 from leaking out.

[0047] One end of the air pump 16 away from the insertion tube 1 17 is fixedly connected to the insertion tube 2 20, and a plurality of exhaust grooves 21 are provided on the insertion tube 20. When it is necessary to deflate the binding airbag 7 and the compression airbag 8, the air pump 16 is turned over, and the insertion tube 20 is used to push the air-closing plate 12 to move toward the inside of the air nozzle 10. At this time, the airway 11 is open, and the gas inside the binding airbag 7 or the compression airbag 8 is first discharged from the airway 11, and then discharged from the exhaust groove 21, thereby realizing the deflation function.

[0048] In summary, the patient's limbs can be bound by the tourniquet 1 and the bandage 2. When blood penetrates, the water-soluble layer 6 is ablated to allow the hemostatic drug layer 5 to penetrate. Then, the binding force of the tourniquet 1 and the coagulation force of the hemostatic drug layer 5 are used to achieve a double hemostatic effect. However, this function can only be applied to a small amount of bleeding.

[0049] The air pump 16 and related components are used to inject air into the binding airbag 7. Since the binding airbag 7 is annularly bound around the limb, when the binding airbag 7 is filled with air, the binding airbag 7 surrounding the limb squeezes the limb through the squeezing force of expansion, thereby blocking the circulation of blood vessels and preventing the penetration of venom.

[0050] The air pump 16 and related components are used to inject air into the compression airbag 8. Since the compression airbag 8 is spherical and is located on the upper side of the limb bleeding point close to the heart, the compression airbag 8 is expanded and squeezed to squeeze the blood vessels to stop continuous bleeding. At the same time, the coagulation power of the hemostatic drug layer 5 is used to accelerate coagulation, thereby achieving a dual hemostatic effect.

[0051] In addition, the air pump 16 and related components can be reused, reducing material consumption and transportation costs;

[0052] Another embodiment of the above-mentioned method is to move the hemostatic drug layer 5 and the water-soluble layer 6 out of the interior of the tourniquet 1 and set them up separately. The hemostatic drug layer 5 and the water-soluble layer 6 are connected to the tourniquet 1 by Velcro. The hemostatic drug layer 5 and the water-soluble layer 6 are arranged on the side close to the human body. In this way, only the hemostatic drug layer 5 and the water-soluble layer 6 need to be replaced, which further improves the reuse rate of the equipment and reduces the medical use cost.

[0053] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
