Description

Technical Field

[0001] The invention relates to a hemostatic device, in particular to a nasal hemostatic device. Background Art

[0002] When the nose is bleeding, most people will choose to use tissue paper, gauze and other fillers to stop the bleeding. However, there are many reasons for nose bleeding, such as dry nose, allergic rhinitis, inflammation, impact and so on. Before the tissue paper is inserted into the nasal cavity, it is in a dry state. After entering the nasal cavity, it will scrape the inner wall of the nasal cavity, which can easily increase the amount of bleeding. At the same time, it is easy to cause adhesion after absorbing blood stains. Therefore, after removal, it is easy for tissue fragments, blood clots and other foreign objects to remain in the nasal cavity, which will bring difficulties to healing.

[0003] In response to the above problems, the existing patent, application number: 202010214308.1, the present invention proposes a nasal packing hemostat, including a filling sponge head, characterized in that: it also includes a liquid storage bottle body, the liquid storage bottle body is provided with a filling liquid, the liquid storage bottle body is provided with a liquid outlet pipe connected to the inner cavity of the liquid storage bottle body, the filling sponge head is covered on the outer wall of the liquid outlet pipe, the outer wall of the liquid outlet pipe is provided with a liquid outlet hole, the inner wall of the end of the liquid outlet pipe facing the liquid storage bottle body is provided with a sealing plug, the sealing plug is provided with a push rod, the end of the push rod passes through the liquid outlet pipe and extends toward the end of the filling sponge head, and the outer wall of the sealing plug facing the side of the push rod or the push rod near the sealing plug position is provided with an anti-retraction device evenly distributed along the circumferential direction of the sealing plug or the push rod, which can expand along the radial direction of the liquid outlet pipe. This application softens the filling sponge head by squeezing the filling liquid into the filling sponge head, reduces the scratching of the nasal mucosa when it is inserted into the nasal cavity, improves comfort, and at the same time, the filling sponge head is squeezed with the bleeding site to achieve rapid hemostasis.

[0004] However, this application still has some problems. After the ejector rod is back-pressed to disengage the sealing plug, the liquid storage bottle body is squeezed to discharge the filling liquid therein. When the ejector rod is back-pressed excessively and the top end extends into the ejection hole, the filling liquid will continue to flow out of the ejection hole; at the same time, once the sealing plug is detached from the liquid outlet tube, the liquid outlet tube cannot be blocked again, and the filling liquid will be squeezed out every time the liquid storage bottle body is squeezed. During the process of nasal hemostasis, unintentional touching will cause the filling liquid to be squeezed out again, and excessive filling liquid can easily flow into the deep nasal cavity, causing danger.

[0005] In view of the above problems, people need a nasal hemostasis device to meet the needs of nasal hemostasis. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0031] An embodiment of the present application provides a nasal hemostasis device.

[0032] Embodiment 1, as Figure 1 shown.

[0033] A nasal hemostasis device comprises a filling sponge head 1 and a liquid storage bottle body 2. The liquid storage bottle body 2 is filled with a filling liquid. The liquid storage bottle body 2 is provided with a liquid outlet pipe 3 connected to the inner cavity of the liquid storage bottle body 2. A liquid guide tube 4 is provided on the top of the liquid outlet pipe 3, and the liquid guide tube 4 is provided with a plurality of groups of liquid guide holes 5 at equal intervals from top to bottom. The filling sponge head 1 is bonded to the outer wall of the liquid guide tube 4 in a point-contact manner.

[0034] When in use, the liquid storage bottle body 2 is pressed to allow the filling liquid inside to enter the liquid guide tube 4 from the liquid outlet tube 3, and then infiltrate the filling sponge head 1 through the liquid guide hole 5. Finally, the filling sponge head 1 is inserted into the nasal cavity to stop bleeding.

[0035] By squeezing the filling liquid into the filling sponge head 1 to soften it, the scraping of the nasal mucosa when inserted into the nasal cavity is reduced, and the comfort is improved; at the same time, the filling sponge head 1 is squeezed with the bleeding site to achieve rapid hemostasis, and the filling liquid can effectively dilute the accumulated excess blood and reduce the coagulation performance of the excess blood, preventing adhesion to the nasal mucosa when it is removed; at the same time, because the filling liquid can keep the nasal cavity moist, the size of the blood scab is reduced, and the plate-like blood scab in the nasal mucosa is avoided from touching the nose after hemostasis is completed, which causes the wound to crack again due to rigid dislocation. The end of the filling sponge head is rounded, which is convenient for insertion into the nasal cavity when used.

[0036] The surface of the liquid guide tube 4 located in the filling sponge head 1 is provided with a plurality of contraction sections 6 at equal intervals, and the filling sponge head 1 fits snugly with the contraction sections 6. The contraction sections 6 increase the contact area between the liquid guide tube 4 and the filling sponge head 1, making it more securely fixed; at the same time, the flexibility of the liquid guide tube 4 is also increased, making it easier to insert into the nasal cavity. The liquid guide hole 5 is located in the middle of the contraction section 6, so that the filling sponge head 1 is soaked more evenly. The outer wall of the filling sponge head 1 is provided with a plurality of contraction rings 7 arranged at intervals along its axial direction, which can improve the elastic contraction ability of the outer wall of the filling sponge head 1, making it more fit when inserted into the nostrils and reducing the foreign body sensation.

[0037] The liquid outlet pipe 3 is a two-stage variable diameter pipe body, the lower diameter of the liquid outlet pipe 3 is larger than the upper diameter, and a step is formed at the change point between the upper diameter and the lower diameter, which is convenient for blocking by the step. A sealing plug 8 is arranged at the lower part of the inner cavity of the liquid outlet pipe 3, and the top of the sealing plug 8 contacts the step, so that the sealing plug 8 is at the deepest part of the lower part of the liquid outlet pipe 3 to prevent it from accidentally coming out. The sealing plug 8 is a vertical double diamond structure, which is convenient for inserting and removing the sealing plug 8. The sealing plug 8 is detachably extruded and connected to the lower part of the inner cavity of the liquid outlet pipe 3, and the widest part of the diameter of the sealing plug 8 is slightly larger than the diameter of the lower part of the liquid outlet pipe 3, which increases the sealing performance and the reliability of the sealing. A lifting rod 9 is arranged at the bottom of the sealing plug 8, and the bottom end of the lifting rod 9 extends to the outside of the liquid storage bottle 2, and a liquid outlet control assembly 10 is arranged. The lifting rod 9 is sealed and connected to the liquid storage bottle 2 to prevent leakage during the movement of the lifting rod. A telescopic protrusion 11 is provided at the connection between the liquid storage bottle body 2 and the lifting rod 9. The connection between the lifting rod 9 and the liquid storage bottle body 2 is located at the top of the telescopic protrusion 11, which increases the movable range of the connection without damage, and avoids damage to the connection between the lifting rod 9 and the liquid storage bottle body 2 when the lifting rod 9 is pulled out. When the lifting rod 9 is pulled downward, the connection between the telescopic protrusion 11 and the lifting rod 9 moves downward synchronously.

[0038] The liquid outflow control component 10 controls the sealing plug 8 to separate from the inner cavity of the liquid outlet tube 3 through the lifting rod 9, so that the filling liquid in the liquid storage bottle body 2 enters the liquid guide tube 4 from the liquid outlet tube 3 and then infiltrates the filling sponge head 1.

[0039] The liquid outflow control assembly 10 includes an extrusion member 12, a fingertip limiter 13, a finger ring limiter 14, a guide block 15, and a return spring 16. The lower part of the liquid storage bottle 2 is covered with an extrusion member 12, and the extrusion member 12 is in a U-shaped structure. On the one hand, it is convenient to squeeze the liquid storage bottle 2 so that the filling liquid flows out faster; on the other hand, it plays a role of roughly limiting the liquid storage bottle 2. When the sealing plug 8 is inserted and removed by the lifting rod 9, the liquid storage bottle 2 is prevented from twisting arbitrarily, causing the filling liquid inside to be squeezed and sprayed out unintentionally. Fingertip limiters 13 are respectively arranged on both sides of the bottom end of the extrusion member 12. The fingertip limiter 13 is an I-shaped structure. Compared with the ring structure, the I-shaped structure can limit the fingertips, which is convenient for using both hands at the same time. When both hands are used at the same time, when the fingers of both hands are placed on both sides of the fingertip limiter 13, it is easier for the user to exert force to operate and remove or insert the sealing plug 8 more quickly; when one hand pinches the fingertip limiter 13, two fingers can be used to directly pinch the two sides of the I-shape for easy operation. A guide block 15 is provided between the two fingertip limiters 13, and a guide hole 17 is provided at the center of the guide block 15. The bottom end of the lifting rod 9 passes through the guide hole 17, and a finger ring limiter 14 is provided. By pulling the finger ring limiter 14, the lifting rod 9 can be pulled downward to pull the sealing plug 8 out of the liquid outlet pipe 3. The guide block 15 limits the moving direction of the lifting rod 9, and cooperates with the extrusion member 12 to make it easier to insert and remove the sealing plug 8. A return spring 16 is provided between the finger ring limiter 14 and the guide block 15. When squeezing the filling liquid, the operator is required to pull out the finger ring limiter 14 all the time. When the operator lets go, the finger ring limiter 14 returns under the pulling force of the return spring 16, thereby driving the lifting rod 9 to move upward, so that the sealing plug 8 is inserted into the liquid outlet pipe 3 for sealing.

[0040] A ventilation component 18 is arranged in the liquid guiding tube 4 .

[0041] The ventilation assembly 18 includes a ventilation hose 19, an annular ventilation piece 20, a connecting ventilation piece 21, and an air guide tube 22. A ventilation hose 19 is provided in the liquid guide tube 4, and a gap is left between the ventilation hose 19 and the side wall of the liquid guide tube 4 so that the filling liquid can flow without being affected. The top of the ventilation hose 19 extends to the outer end of the liquid guide tube 4, and the ventilation hose 19 and the liquid guide tube 4 are sealed and connected to prevent the filling liquid from flowing out through the connection. A plurality of connecting ventilation pieces 21 are provided at the bottom of the ventilation hose 19, and an annular ventilation piece 20 is provided on the outside of the liquid outlet pipe 3. The outer end of the connecting ventilation piece 21 extends to the outside of the liquid outlet pipe 3 and is connected to the annular ventilation piece 20. There are three connecting ventilation pieces 21, which are distributed at an interval of 60° between each other. This makes the air circulation smoother and also minimizes the impact on the extrusion of the filling liquid to avoid excessive extrusion pressure. An air duct 22 is arranged outside the annular vent 20, and air flows through the ventilation hose 19, the connecting vent 21, the annular vent 20, and the air duct 22 in sequence. When in use, the patient can breathe normally through the unobstructed airway formed by the ventilation hose, the connecting vent, the annular vent, and the air duct. A positioning cover 23 is arranged at the top of the ventilation hose 19, and the positioning cover 23 is funnel-shaped. On the one hand, it can prevent the filling sponge head 1 from clogging the port of the air duct 22, and on the other hand, it can enlarge the port of the formed airway to make breathing smoother.

[0042] When the present invention is used:

[0043] The medical staff holds the liquid storage bottle body, pulls the finger ring limiter with fingers, and then squeezes the squeezing piece to squeeze out the filling liquid to soak the filling sponge head.

[0044] When the filling sponge head is soaked, it is inserted into the patient's nasal cavity, and the filling sponge head is squeezed with the bleeding part to achieve rapid hemostasis. During the hemostasis period, the patient can breathe freely through the unobstructed airway formed by the ventilation component.
