Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an adjustable nasal cavity rapid hemostasis and ventilation device. Background Art

[0002] The nose includes the external nose, nasal cavity and paranasal sinuses, which are rich in blood and closely adjacent to important surrounding structures such as the brain, eye sockets and oral cavity. War injuries, traffic injuries and various natural disasters often lead to severe bleeding after nasal and facial trauma, and even shock, suffocation and aspiration due to bleeding. Therefore, the treatment of nosebleeds should first pay attention to hemostasis and keep the airway open. In the prior art, nasal medical PVF hemostatic gauze is used for the treatment of nosebleeds, nasal packing after surgery and sustained-release carriers for nasal administration. It has high absorbency and quickly expands into a highly elastic sponge after absorbing liquid, filling the nasal cavity according to the shape of the packing site, providing uniform support and compression. Although medical sponge PVF hemostatic gauze is widely used in clinical practice, it still has many shortcomings, including: 1. After PVF is packed after surgery, the nasal cavity is completely blocked. After it is fully expanded by absorbing blood, it has great supporting force. On the day after surgery, patients often complain of shortness of breath, mouthache, headache, and orbital pain; 2. Because the medical sponge PVF hemostatic gauze absorbs enough blood when it is taken out, the pressure is very high, and the patient is in great pain. For younger patients, it is more likely to cause psychological trauma; 3. The function of medical sponge PVF hemostatic gauze is only to compress the nasal cavity to achieve the purpose of hemostasis. There are no active substances on the surface of the sponge that promote postoperative mucosal healing. Molecular components; 4. Medical sponge PVF hemostatic gauze cannot be designed with different packing pressures for different patients, and cannot be personalized to achieve hemostatic effects. Secondly, because the pressure cannot be adjusted, it is easy to cause complications such as mucosal ischemia and necrosis due to excessive pressure or prolonged time. Summary of the invention

[0003] The purpose of the present invention is to provide an adjustable nasal rapid hemostasis and ventilation device which can achieve rapid hemostasis, reduce scar formation and ventilate, so as to solve the above problems existing in the prior art.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] The present invention provides an adjustable nasal rapid hemostasis and ventilation device, which includes an extrusion airbag, a container, a valve and a sensing airbag. A hemostatic factor is arranged on the outer surface of the extrusion airbag through hemostatic fibers. An airway is arranged inside the extrusion airbag. A ventilation tube is arranged in the airway, and both ends of the ventilation tube extend out of the airway to ensure ventilation of the nasal cavity after the extrusion airbag is filled into the nasal cavity. The extrusion airbag has good elasticity and conformability. A reactant is arranged in the container. The reactant reacts with the hemostatic factor to generate a gel-like substance in contact with the nasal cavity. The valve is connected to the sensing airbag, and the sensing airbag is connected to the extrusion airbag through a catheter to judge the pressure condition in the extrusion airbag and can autonomously adjust the pressure according to the filling time.

[0006] Furthermore, the ratio of the length of the extruded airbag to the length of the ventilation tube is 4:5.

[0007] Furthermore, the length of both ends of the ventilation tube extending out of the airway is 0.8 cm.

[0020] The technical solution provided by the embodiments of the present invention is described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 , Figure 2As shown, the adjustable nasal rapid hemostasis and ventilation device of this embodiment includes an extrusion airbag 1, a container, an induction airbag 3 and a valve 4. A hemostatic factor is arranged on the outer surface of the extrusion airbag 1 through hemostatic fibers. The arrangement of the hemostatic fibers can improve the hemostatic effect. A penetrating airway is arranged inside the extrusion airbag 1, and a ventilation tube 2 is arranged in the airway. Both ends of the ventilation tube 2 extend out of the airway to ensure ventilation of the nasal cavity after the extrusion airbag is filled into the nasal cavity. At this time, the extrusion airbag has good elasticity and conformability.

[0022] Among them, there is a reactant in the container, and the reactant reacts with the hemostatic factor to generate a gel-like substance that contacts the nasal cavity. The valve 4 is connected to the sensing airbag 3, and the sensing airbag 3 is connected to the extrusion airbag 1 through a catheter to determine the pressure situation in the extrusion airbag 1 and can autonomously adjust the pressure according to the filling time.

[0023] In this embodiment, by setting the squeezing airbag 1, since the squeezing airbag 1 is soft, has good elasticity and conformability, it can expand with the shape of the nasal cavity, meet the filling of irregular shapes in the nasal cavity, and have a good hemostatic effect; and, by setting the hemostatic factor, it can stimulate the regeneration of blood vessels by activating platelets and reduce the formation of scabs. When in use, the reactant reacts with the hemostatic factor and is inserted into the nasal cavity to generate a gel-like substance, which is conducive to platelet aggregation and rapid formation of blood clots. At the same time, an infiltration environment can be formed around the bleeding site, accelerating the formation of epithelial tissue and promoting the healing of the wound, thereby reducing and avoiding adhesion and late scar formation, and avoiding rebleeding and the patient's pain during removal; through the airway running through the inside of the squeezing airbag 1, the ventilation of the nasal cavity can be guaranteed after the squeezing airbag 1 is filled into the nasal cavity.

[0024] At the same time, by setting up the sensing airbag 3, the pressure situation in the squeezing airbag 1 can be judged, the pressure of the squeezing airbag 1 in the nasal cavity can be sensed, and the pressure can be inflated through the valve 4 to apply pressure to the wound surface to enhance the hemostatic effect. Secondly, the pressure can be adjusted autonomously according to the packing time, so that it can not only completely control the bleeding, but also minimize the patient's pain and avoid the risk of local ischemia and necrosis caused by continuous pressure.

[0025] Preferably, the ratio of the length of the extruded airbag 1 to the length of the ventilation tube 2 is 4:5, and the lengths of both ends of the ventilation tube 2 extending out of the airway are 0.8 cm respectively.

[0026] Wherein, the ventilation pipe 2 is made of silica gel.

[0027] In addition, the container is a syringe, and the reactant is sterile distilled water or water for injection. By using a syringe, the operation can be convenient.

[0028] Optionally, the extrusion airbag 1, the sensing airbag 3 and the catheter are made of polyvinyl chloride. By using the extrusion airbag 1 and the sensing airbag 3 made of polyvinyl chloride, the consistency of pressure can be ensured.

[0029] In addition, the catheter is provided with fixed wings, and the setting of the fixed wings can facilitate the fixation of the catheter and the sensing airbag 3.

[0030] The adjustable nasal rapid hemostasis and ventilation device of the present invention can autonomously adjust the pressure according to the packing time by providing an extrusion airbag and an induction airbag, so that the extrusion airbag can not only completely control the bleeding, but also minimize the patient's pain and improve the comfort. The device is easy to carry and easy to operate as a whole, and can take into account both nasal hemostasis and ventilation, which helps to improve the success rate of first aid in the field.

[0031] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
