Description

Technical Field

[0001] The invention relates to a nasal hemostasis device, which is used for hemostasis after nasal blood vessel bleeding and belongs to the technical field of medical devices. Background Art

[0002] Nosebleed is one of the common diseases in outpatient clinics. It is more common in spring and autumn. In mild cases, there is only blood in the mucus, while in severe cases, it can cause hemorrhagic shock. The site of the disease can be anywhere in the nasal cavity. In adolescents and children, it is mostly the bleeding area in the front of the nasal cavity, namely the Li area, while in middle-aged and elderly people, it is mainly concentrated in the back of the nasal cavity, mostly the nasal-nasopharyngeal venous plexus. The focus of nosebleed diagnosis is to find out the cause and the location of the bleeding point. The cause of nosebleed is more complicated and can be roughly divided into two categories, namely local factors and systemic factors. Local factors include: trauma, tumors of the nasal cavity, paranasal sinuses, and nasopharynx, foreign bodies in the nasal cavity, barotraumatic sinusitis, etc.; systemic factors include: acute febrile infectious diseases, heart and circulatory system diseases, hemorrhagic diseases, liver and kidney diseases, and rheumatic fever, etc. Different causes of nosebleeds can lead to different locations of bleeding points and different amounts of bleeding. For example, severe head and facial trauma that injures the maxillary artery, anterior and posterior ethmoid arteries, and sphenopalatine artery will cause heavy and severe bleeding, often leading to fatal nosebleeds. Arterial bleeding caused by hypertension, arteriosclerosis, hypertensive nephritis, eclampsia and other diseases often results in bleeding in the middle and posterior segments of the nasal cavity or the top of the nasal cavity. The bleeding is bright red, fluctuating, and can stop suddenly. Clinically, when a patient suddenly has a large amount of nose bleeding, there is often no time to analyze the cause, and the only treatment is symptomatic treatment to stop the bleeding first to avoid serious consequences caused by large amounts of bleeding.

[0003] In the prior art, medical staff first use an anterior rhinoscope to observe whether there are bleeding points in the nasal cavity and the front of the nasal septum. If the anterior rhinoscope cannot find the bleeding point, they use a nasal endoscope to find the bleeding point in the back of the nasal cavity, enter the nasopharynx and the posterior nasal cavity through the middle nasal meatus, observe the source of blood flow, find the specific location of the bleeding point, and finally use vaseline gauze or hemostatic balloon packing. However, in reality, finding the bleeding point is very difficult and time-consuming. If the patient continues to bleed heavily during the search time, it is likely to cause hemorrhagic shock to the patient and serious panic to the patient's family members.

[0004] Therefore, researchers in this field are in urgent need of developing a nasal hemostasis device that can quickly determine the location of nasal bleeding points, promptly and effectively control nasal bleeding, and allow patients to wear a comfortable nasal hemostasis device during treatment.

[0058] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the claims.

[0059] The present invention provides a nasal hemostasis device, which is used for hemostasis of nasal bleeding points and determination of bleeding locations. The first embodiment of the nasal hemostasis device provided by the present invention is introduced below.

[0060] like Figure 1 As shown, in the first embodiment of the nasal hemostasis device provided by the present invention, the nasal hemostasis device includes a support body 1 and an air bag 2. The support body 1 is slender and made of medical-grade flexible material. One end of the support body 1 provided with the air bag 2 is arranged inside the human nasal cavity, and the other end is arranged outside the human nasal cavity. The support body 1 is formed by enclosing a tube wall 13. The inner hollow of the tube wall 13 is a nasal ventilation cavity 10. When the nasal cavity is in a hemostasis state, the nasal ventilation cavity 10 is used to ventilate the human nose or discharge nasal coagulation. The air bag 2 is slender and made of conformable medical silicone material or rubber material. Before the air bag 2 is not inflated, it is attached to one end of the support body 1 placed in the nasal cavity.

[0061] refer to Figure 1 , Figure 2As shown, in order to quickly determine the location of nasal bleeding points and control nasal bleeding in a timely and effective manner, the device also includes a weak connection component 3, which is specifically an annular protrusion 31 protruding from the inner surface of the airbag 2, and an annular groove 32 arranged on the outer surface of the support body 1. The annular protrusion 31 is detachably engaged in the annular groove 32. The two weak connection components 3 separate the airbag 2 into three parts, namely, the first airbag 21, the second airbag 22 and the third airbag 23. The air outlet 11b is located inside the first airbag 21. When the gas passage 11 inflates the airbag 2, the first airbag 21 is inflated first. After inflation, the outer surface of the first airbag 21 is pressed against the deep part of the nasal cavity. If the first airbag 21 stops bleeding immediately after inflation, it means that the bleeding point is located in the deep part of the nasal cavity where the first airbag 21 is located. If the bleeding does not stop, continue to inflate the first airbag 21. The first weak connection component 3 is used to prevent the bleeding from stopping. The connecting component 3 releases the separation of the airbags 2, and the second airbag 22 is inflated after the first airbag 21 is inflated. After the expansion, the outer surface of the second airbag 22 covers the middle part of the nasal cavity. If the second airbag 22 stops bleeding immediately after it is inflated, it means that the bleeding point is in the middle part of the nasal cavity where the second airbag 22 is located. If the bleeding does not stop, the first airbag 21 continues to be inflated, and the second weak connection component 3 releases the separation of the airbags 2. The third airbag 23 is inflated after the first airbag 21 and the second airbag 22 are inflated. After the expansion, the outer surface of the third airbag 23 covers the shallower part of the nasal cavity. If the third airbag 23 stops bleeding immediately after it is inflated, it means that the bleeding point is in the shallower part of the nasal cavity where the third airbag 23 is located. In this way, the nasal cavity expands from the deep part to the shallower part of the nasal cavity, and then expands and stops bleeding in sequence from the deep part of the nasal cavity toward the nostril. The bleeding position of the nasal cavity can also be found in sequence. In addition, the engagement strengths of the two weak connection components 3 are different. The engagement strength of the weak connection component 3 separating the first airbag 21 and the second airbag 22 is smaller than the engagement strength of the weak connection component 3 separating the second airbag 22 and the third airbag 23 .

[0062] refer to Figure 1 , Figure 2As shown, in order to ensure that the nasal hemostasis device is in conformity with the angle inside the human nasal cavity and is more suitable for the bleeding position of the human nasal cavity to stop bleeding, a steering part 12 is provided on the support body 1 between the first airbag 21 and the third airbag 23, specifically a section of a corrugated tube 121 arranged on the support body 1, located between the first airbag 21 and the third airbag 23. When the corrugated tube 121 is bent, a part is squeezed and shortened, and the opposite side is stretched and lengthened, so that the support body 1 can be bent, and the first airbag 21 and the third airbag 23 are bent into an angle suitable for the human nasal cavity, so that the airbag 2 is more suitable for the bleeding position of the human nasal cavity, and the hemostasis effect is enhanced. The corrugated tube 121 is made of medical grade stainless steel or medical grade plastic. Of course, the steering part 12 can also be provided on the support body 1 between the first airbag 21 and the second airbag 22, and on the support body 1 between the second airbag 22 and the third airbag 23.

[0063] refer to Figure 3 As shown, a pressure relief port 11c is provided on the gas passage 11 of the support body 1. The pressure relief port 11c is located at the lower part of the support body 1 and is connected to the airbag cavity 20 through the gas passage 11. A pressure relief valve 14 is sleeved on the outer surface of the support body 1. The pressure relief valve 14 is made of medical rubber material. The sealing sleeve of the pressure relief valve 14 is arranged outside the pressure relief port 11c. When the internal pressure of the airbag cavity 20 is at a safe threshold, the pressure relief port 11c is kept leak-proof. When the airbag cavity 20 exceeds the safe pressure relief threshold, the pressure relief valve 14 at the pressure relief port 11c connected to the cavity opens to relieve the pressure of the airbag cavity 20. The safe pressure relief threshold is adjusted according to the patient's condition. It is recommended that it should not be greater than 4Kpa to avoid damage to the nasal cavity caused by excessive compression.

[0064] Continue to refer Figure 3 As shown, the device is also provided with a one-way valve 54, which is used to block the air inlet 11a to prevent the gas inside the airbag cavity 20 from leaking from the air inlet 11a after inflation is completed.

[0065] refer to Figure 4 As shown, a cryogenic liquid sac 4 is also provided inside the airbag 2, and a cryogenic liquid, such as ice water, cryogenic gel, etc., is filled into the sac cavity 40 of the cryogenic liquid sac 4 through a sac pipeline. When the cryogenic liquid sac 4 is filled and expanded, the outer surfaces of the cryogenic liquid sac 4 are respectively attached to the inner surfaces of the airbag 2, and the low temperature is transferred to the mucosa in the nasal cavity, thereby assisting the nasal blood vessels to stop bleeding quickly.

[0066] refer to Figure 1 , Figure 5As shown, a pressure monitoring component 51 can be provided inside the airbag cavity 20. The pressure monitoring component 51 is used to monitor and display the gas pressure inside the cavity. When the safety pressure relief threshold is exceeded, active pressure relief can be taken to avoid damage to the inner wall of the nasal cavity caused by excessive pressure. An electromagnetic pressure relief valve 52 is provided at the tail of the support body 1. When the airbag cavity 20 exceeds the safety pressure relief threshold, the electromagnetic pressure relief valve 52 relieves the pressure of the airbag cavity 20. A pit 53 is provided on the outer surface of the airbag 2, and thrombin is provided inside the pit 53. The thrombin is a sterile lyophilized product of thrombin obtained by activating prothrombin. Of course, a hemostatic gel can also be provided on the outer surface of the airbag 2.

[0067] The second embodiment of the nasal hemostasis device provided by the present invention is introduced below.

[0068] refer to Figure 6 As shown, the second embodiment of the nasal hemostasis device provided by the present invention has basically the same structure as the first embodiment, and the difference between the two is that:

[0069] The weak connection component 3 is annular and is a medical adhesive arranged between an outer surface of a section of the supporting body 1 and an inner surface of the airbag 2. The weak connection component 3 has a certain bonding strength, which bonds the airbag 2 to the supporting body 1. After bonding, the airbag 2 is separated into two parts, namely, a first airbag 21 and a second airbag 22. The air outlet 11b is located inside the first airbag 21. When the gas passage 11 inflates the airbag 2, the first airbag 21 is inflated first, and the first airbag 21 is continued to be inflated. The bonding between the airbag 2 and the supporting body 1 is destroyed, and the weak connection component 3 releases the separation of the airbag 2. The second airbag 22 is inflated after the first airbag 21 is inflated. In this way, the first airbag 21 and the second airbag 22 are expanded in sequence from the deep nasal cavity to the nostril. If the bleeding location is located in the deep nasal cavity, the bleeding is controlled after the first airbag 21 is inflated; if the bleeding point is located near the nostril, the second airbag 22 needs to be inflated to stop the bleeding.

[0070] The third embodiment of the nasal hemostasis device provided by the present invention is introduced below.

[0071] refer to Figure 7 As shown, the third embodiment of the nasal hemostasis device provided by the present invention has basically the same structure as the first embodiment, and the difference between the two is that:

[0072] The weak connection component 3 is a magnetic ring buried in the tube wall of the support body 1 and the wall of the airbag 2. The weak connection component 3 located in the support body 1 is arranged opposite to the weak connection component 3 located in the airbag 2. The weak connection component 3 is annular and made of a magnetic material. The weak connection component 3 connects the airbag 2 and the support body 1 by suction. After the connection, the airbag 2 is separated into two parts, namely, the first airbag 21 and the second airbag 22. The air outlet 11b is located inside the first airbag 21. When the gas passage 11 is used to inflate the airbag 2, the air outlet 11b is firstly inflated from the first airbag 21. The first airbag 21 is inflated and expanded, and the first airbag 21 continues to be inflated. The suction between the airbag 2 and the supporting body 1 is destroyed, and the weak connection component 3 releases the separation of the airbag 2. The second airbag 22 is inflated after the first airbag 21 is inflated. In this way, the first airbag 21 and the second airbag 22 are inflated in sequence from the deep part of the nasal cavity to the nostril. If the bleeding location is located in the deep part of the nasal cavity, the bleeding will be controlled after the first airbag 21 is inflated; if the bleeding point is located near the nostril, the second airbag 22 needs to be inflated to stop the bleeding.

[0073] The fourth embodiment of the nasal hemostasis device provided by the present invention is introduced below.

[0074] refer to Figure 8 As shown, the fourth embodiment of the nasal hemostasis device provided by the present invention has basically the same structure as the first embodiment, and the difference between the two is that:

[0075] The weak connection component 3 is annular and is a thin film wrapped around the outer surface of the airbag 2. A tear line is provided on the thin film. When subjected to external force, the thin film tears along the tear line. The weak connection component 3 binds the airbag 2 and the supporting body 1 together. After binding, the airbag 2 is separated into two parts, namely, a first airbag 21 and a second airbag 22. The air outlet 11b is located inside the first airbag 21. When the gas passage 11 inflates the airbag 2, the first airbag 21 is inflated first, and the first airbag 21 continues to be inflated. The weak connection component 3 is torn, and the weak connection component 3 releases the separation of the airbag 2. The second airbag 22 is inflated after the first airbag 21 is inflated. In this way, the first airbag 21 and the second airbag 22 are expanded in sequence from the deep nasal cavity to the nostril. If the bleeding location is located in the deep nasal cavity, the bleeding is controlled after the first airbag 21 is inflated; if the bleeding point is located near the nostril, the second airbag 22 needs to be inflated to stop the bleeding.
