Description

Technical Field

[0001] The present invention relates to the technical field of nasal hemostasis devices, in particular to a convenient-to-use nasal hemostasis device for patients with blood diseases. Background Art

[0002] Hematopoietic system diseases, commonly known as blood diseases, are diseases that originate in the hematopoietic system and mainly affect the hematopoietic system. Bleeding is also one of the important clinical manifestations of blood diseases, mainly manifested as bleeding in the skin and mucous membranes, such as skin petechiae, purpura, ecchymosis, and hematoma. It can also manifest as nosebleeds, gingival bleeding, and menorrhagia. Therefore, when a patient has nasal bleeding, in order to avoid blood flowing straight or accumulating and causing reflux, the patient's nasal cavity needs to be immediately stopped from bleeding. The current traditional hemostasis method requires manual use of hemostatic tools such as gauze to reach into the nasal cavity to cover the bleeding points and stop bleeding. In the process of extracting the gauze, the gauze and the wound are closely attached to each other, which can easily cause the mucosa to be damaged again, prolonging the wound healing time and causing repeated bleeding. In addition, long-term manual hemostasis operations consume medical resources and a lot of time.

[0003] Therefore, in order to solve the above problems, we propose a convenient nasal hemostasis device for patients with blood diseases. Summary of the Invention

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1 and Figure 4As shown, a convenient nasal hemostasis device for patients with blood diseases includes two symmetrically arranged ventilation tubes 1. The outer sides of the two ventilation tubes 1 are fixedly sleeved with expansion air bags 2, and the expansion air bags 2 are arranged in a ring shape.

[0030] like Figure 1 As shown, a plurality of hemostatic tampons 17 are fixedly provided on the outside of the expansion airbag 2. The plurality of hemostatic tampons 17 are wrapped around the center of the expansion airbag 2 and fixed on the outside of the expansion airbag 2. By increasing the size of the expansion airbag 2 and filling the nasal cavity, the plurality of hemostatic tampons 17 can fully contact the inner wall of the nasal cavity, block the surface position, and complete the hemostasis work.

[0031] like Figure 1 As shown, the outer lower ends of the two expansion airbags 2 are connected to an air outlet pipe 3, and the two air outlet pipes 3 are commonly connected to a three-way valve 4. The bottom of the three-way valve 4 is connected to an air inlet pipe 5, and the lower end of the tube wall of the air inlet pipe 5 is fixedly connected to an inflation airbag 6. The tube wall of the air inlet pipe 5 is fixedly sleeved with a first one-way valve 7, which can allow external gas to enter the expansion airbag 2 through the compression and rebound of the inflation airbag 6, thereby completing the filling of the expansion airbag 2 in the nasal cavity.

[0032] like Figure 3 As shown, the lower ends of the two ventilation tubes 1 are fixedly sleeved with an annular plate 8, and the outer side of the annular plate 8 is rotatably sleeved with a suction tube 9. The lower end of the suction tube 9 is arranged in an annular shape, and the lower ends of the side walls of the two suction tubes 9 are connected with a liquid inlet pipe 10. The lower ends of the two liquid inlet pipes 10 are commonly connected with a liquid outlet pipe 11. The upper end of the liquid outlet pipe 11 is fixedly connected with a suction airbag 12. The inflatable airbag 6 and the suction airbag 12 are fixedly connected. The upper ends of the tube walls of the two suction tubes 9 are fixedly sleeved with a second one-way valve 13, which can enable the inflatable airbag 6 and the suction airbag 12 to work simultaneously, so that the overflowed blood can be collected through the suction tube 9.

[0033] like Figure 1 As shown, the air intake directions of the first one-way valve 7 and the second one-way valve 13 are opposite, and springs 14 are provided inside the inflatable airbag 6 and the liquid suction airbag 12. The two ends of the two springs 14 are fixedly connected to the inner walls of the inflatable airbag 6 and the liquid suction airbag 12 respectively, so that the blood suction direction and the gas entry direction are opposite.

[0034] like Figure 3As shown, a rotating assembly is provided between the two suction tubes 9 and the annular plate 8 on the same side. The rotating assembly includes a torsion spring 18, which is sleeved on the outside of the ventilation tube 1 and located below the suction tube 9. The two ends of the torsion spring 18 are fixedly connected to the bottom of the suction tube 9 and the lower end of the outer side of the annular plate 8, respectively. Push rods 19 are fixedly provided at both ends of the bottom of the two suction tubes 9. The multiple push rods 19 are all L-shaped. A drawstring 20 is fixedly provided between two adjacent push rods 19. The drawstring 18 can pull the push rod 19 and cooperate with the torsion of the torsion spring 18 to allow the suction tube 9 to rotate back and forth around the nostril to complete the extraction and collection of blood flowing out of various parts of the nasal cavity.

[0035] like Figure 2 As shown, both ends of the two ventilation tubes 1 are provided with hemostatic ventilation components, which include a non-woven filter membrane 15 and an elastic band 16. The non-woven filter membrane 15 covers and wraps the tube mouth of the ventilation tube 1, and the elastic band 16 is sleeved on the outside of the end of the ventilation tube 1. The elastic band 16 is sleeved on the outside of the non-woven filter membrane 15. Through the setting of the non-woven filter membrane 15, when the expansion balloon 2 is expanded inside the nasal cavity, normal nasal breathing can be completed through the ventilation tube 1, reducing damage to the patient's body.

[0036] In summary, when using this convenient nasal hemostasis device for patients with hematological diseases, medical staff insert the two ventilation tubes 1 together with the expansion airbags 2 into the patient's nasal cavity, and quickly press the liquid suction airbag 12 and the inflation airbag 6 at the same time, so that the two airbags perform repeated expansion and contraction movements under the compression and rebound of the internal spring 14. During the expansion and contraction process of the inflation airbag 6, the gas enters the three-way valve 4 from the outside through the first one-way valve 7 and the air inlet pipe 5, and then separates and enters the two outlet pipes 3, and the gas in the outlet pipe 3 quickly enters the expansion airbag 2, causing the expansion airbag 2 to expand rapidly. As the inflation airbag 6 is continuously pressed, the two expansion airbags 2 are fully filled in the nasal cavity, and multiple hemostatic tampons 17 and The inner wall of the nasal cavity is in contact with the bleeding wound inside the nasal cavity, thereby completing the hemostasis work. At the same time, the expansion and contraction of the liquid suction airbag 12 generates a suction force, which is transmitted to the liquid suction pipe 3 through the liquid suction tube 10 and the second one-way valve 13, so that the protruding tube mouth at the top of the liquid suction pipe 3 sucks the blood overflowing from the nasal cavity. After being sucked, the blood enters the liquid suction airbag 12 and is discharged through the liquid outlet pipe 11 after the liquid suction airbag 12 is compressed. During the blood absorption process, medical staff can pull the drawstring 20, and at the same time, the transmission of the push rod 19 causes the liquid suction pipe 9 to twist the torsion spring and rotate back and forth on the outside of the annular plate 8, so that all the blood overflowing from various parts of the nasal cavity can be sucked, thereby improving the convenience and efficiency of nasal hemostasis.
