Description

Technical Field

[0001] The utility model belongs to the technical field of nasopharyngeal hemostasis tools, in particular to a nasopharyngeal self-adaptive compression hemostasis device. Background Art

[0002] According to the location of nasal bleeding, it can be divided into anterior nasal bleeding and posterior nasal bleeding. Among them, nasopharyngeal bleeding belongs to a type of posterior nasal bleeding. The nasopharynx is connected to the nasal cavity through the posterior nostril forward, and the back is level with the 1st-2nd cervical vertebrae. It goes down through the nasopharyngeal isthmus and continues to the oropharynx. It can be divided into the anterior wall, posterior wall, top wall, left wall, right wall and bottom wall. The top wall and the posterior wall are transitional, and there is no obvious boundary between the two walls. They are often collectively referred to as the top and posterior walls. There are many reasons for nasopharyngeal bleeding, the most common of which is nasopharyngeal inflammation, such as dry rhinitis, atrophic rhinitis, etc., which leads to dryness and erosion of the nasopharyngeal mucosa and causes bleeding. In addition, nasopharyngeal tumors are also one of the causes of bleeding, such as nasopharyngeal carcinoma. Other causes include nasopharyngeal trauma, nasopharyngeal surgery, etc., which may also cause nasopharyngeal bleeding.

[0003] Commonly used methods of hemostasis for nasal bleeding include local compression hemostasis, electrocoagulation hemostasis, vascular embolization hemostasis and posterior nasal packing hemostasis.

[0004] In clinical work, the difficulty of stopping bleeding in the nasopharynx lies in its deep location and complex surrounding structures, which makes it difficult to accurately find the bleeding point. In addition, when the postoperative nasopharyngeal bleeding is more severe, it can cause hemorrhagic shock in a short period of time, and timely hemostasis is required. When dealing with nasopharyngeal bleeding, commonly used hemostasis methods include local compression hemostasis, posterior nasal packing hemostasis, and electrocoagulation hemostasis.

[0005] Local compression hemostasis usually uses hemostatic cotton balls or gauze for compression, which requires the cooperation of the patient. However, due to the special location of the nasopharynx, the hemostatic position is difficult to determine, and the final hemostatic effect is limited; although electrocoagulation hemostasis is a more advanced hemostatic method, it requires special equipment and high costs, and the requirements for the operator are also higher; posterior nasal packing hemostasis requires the preparation of packing hemostatic cotton balls, which is cumbersome and time-consuming, and blind packing causes greater pain to the patient. Among them, the hemostatic method using cotton balls and gauze will cause blood scabs, so when it is removed, it often bleeds again due to the blood scabs. In addition, when both nasal cavities need hemostasis, due to the influence of the filler (cotton balls, gauze, air bag), the patient can only breathe through the mouth, and the filling time required for compression hemostasis is generally longer, which will increase the patient's pain.

[0006] In addition, when the amount of bleeding is large or the bleeding is severe, blood may sometimes spray out from the patient's nostrils. Since current hemostasis methods require medical staff to observe the nasal cavity closely to stop bleeding, medical staff may be splashed by the blood spraying from the nostrils, making it impossible to ensure their own safety.

[0007] In summary, the current clinical methods have certain limitations, such as the inability to accurately compress bleeding points, slow electrocoagulation hemostasis efficiency and high cost, complicated packing process and great pain for patients, re-bleeding caused by blood scabs, and the risk of blood-borne infection for medical staff, etc. Therefore, it is necessary to further explore more effective and easy-to-operate nasopharyngeal compression hemostasis devices.

[0008] After searching, the existing Chinese utility model document with announcement number CN213129689U discloses a multi-purpose nasopharyngeal dilatation and hemostasis air bag, "including a soft rubber tube and a multi-cystic layer structure, one end of the soft rubber tube is a blind end, and the other end is provided with a water injection valve, the middle section of the soft rubber tube is connected to the multi-cystic layer structure, the multi-cystic layer structure is divided into a first multi-cystic layer structure and a second multi-cystic layer structure, the first multi-cystic layer structure is sleeved inside the second multi-cystic layer structure, the soft rubber tube located at the position of the first multi-cystic layer structure is provided with a plurality of water inlet holes, the end of the second multi-cystic layer structure close to the water injection valve is connected to the drug delivery hose, one end of the drug delivery hose is the drug delivery valve, and the surface of the second multi-cystic layer structure is provided with a plurality of drug outlet holes." However, the utility model still has the above-mentioned limitations and cannot guarantee effective positioning hemostasis. Utility Model Content

[0032] Example 1

[0033] like Figure 1 As shown, this embodiment provides a nasopharyngeal adaptive compression hemostasis device, including an electronic endoscope connected to an external display, and also includes a main body 1 and a hemostasis part 7; the hemostasis part 7 includes an angle adjustment mechanism 9 and an air bag 8 located at the end of the hemostasis part 7; the main body 1 includes a connector 2, an operating passage 4, a gripping part 3, a controller 5 and a display screen 62.

[0034] The connector 2 is located at the end of the body 1, and the hemostatic part 7 is detachably fixed to the end of the body 1 through the connector 2. Specifically, the detachable fixing method is preferably a quick-release connection through an active buckle. There are many related connection methods and structures in the prior art, so as long as they can be implemented, they will not be described here. In this embodiment, the connector 2 is a buckle groove 22 evenly arranged around the end of the body 1, and the top of the hemostatic part 7 is provided with a buckle protrusion 21 that matches the shape and position of the buckle groove 22. The hemostatic part 7 is embedded in the buckle groove 22 of the body 1 through the buckle protrusion 21, so that the hemostatic part 7 and the body 1 can be quickly disassembled.

[0035] The airbag 8 includes an air valve 81 for inflating and deflating the airbag 8, an observation cavity 82 for placing an electronic endoscope, and a through hole 83 for operating an electrocoagulation hemostat or injecting water. The air valve 81 is connected to the airbag 8 and is used to inflate and exhaust air from the airbag 8; the observation cavity 82 is located in the airbag 8 and close to the end of the airbag 8, and is used to place an electronic endoscope to achieve visualization of the bleeding point. The observation cavity 82 is connected to the top of the hemostatic part 7. The cavity wall of the observation cavity 82 is made of an elastic material with good restoring force. It will return to its initial straight state when not under force, and will bend in the direction of force when under force; the through hole 83 runs through the airbag 8 and the outlet of the through hole 83 is located next to the observation cavity 82, and the entrance of the through hole 83 is located at the top of the hemostatic part 7, which is used to ensure that the patient can still breathe smoothly after the airbag 8 is inflated and fits to the nasopharyngeal wall, and can serve as a passage for electrocoagulation hemostasis and water injection. When water is injected, the outlet of the through hole 83 is located above the hemostasis point where the airbag 8 compresses. In other embodiments, a sealing gasket is provided around the entrance of the through hole 83, and the sealing gasket ensures the sealing performance when the hemostatic part 7 and the main body 1 are connected, while avoiding water leakage during the water injection process.

[0036] During production, the airbag 8 can be designed with different sizes, so that in actual operation, the hemostatic part 7 with a suitable airbag 8 size can be removed and replaced according to the patient's actual nasopharyngeal volume; adult patients generally use an airbag 8 with a size of 10ml-20ml, and pediatric patients generally use an airbag 8 with a size of 5ml.

[0037] The operation passage 4 is located on the dominant side, and is provided with an operation entrance and an operation exit. The operation entrance is distributed on the wall of the main body 1 and is close to the end of the main body 1. The exit of the operation passage 4 is located on the end face of the main body 1 and is connected with the observation cavity 82 and the entrance of the through hole 83 of the hemostatic part 7. The operation entrance includes an endoscope hole 41, an electrocoagulation hemostatic hole 42 and a water injection port 43; the endoscope hole 41 is connected to the observation cavity 82 inside the airbag 8 of the hemostatic part 7. When in use, the electronic endoscope enters through the endoscope hole 41 and is sent to the end of the observation cavity 82, and the bleeding of the nasopharynx can be observed through the wall of the airbag 8. At the same time, it can bend synchronously with the adjustment of the airbag 8 by the angle adjustment mechanism 9. The electronic endoscope can use an existing nasal endoscope; the electrocoagulation hemostatic hole 42 and the water injection port 43 are both connected to the through hole 83 of the airbag 8 of the hemostatic part 7.

[0038] The gripping portion 3 is close to the top of the body 1 and is located on the non-dominant hand side. The gripping portion 3 is provided with a power switch 31 and a positioning button 32. The power switch 31 is electrically connected to an external power source. When in use, the non-dominant hand holds the gripping portion 3 and places the finger on the positioning button 32, which is convenient for quickly switching the angle of the airbag 8 and locating the bleeding point. The controller 5 is located inside the body 1 and is electrically connected to the positioning button 32. The positioning button 32 controls the rotation position of the airbag 8 in the nasopharynx through the controller 5.

[0039] One end of the angle adjustment mechanism 9 is fixed to the top of the hemostatic part 7, and the other end is fixed around the observation cavity 82 in the airbag 8. The angle adjustment mechanism 9 is electrically connected to the controller 5 through a connecting piece arranged on the top end surface of the hemostatic part 7, and is controlled by the controller 5 to adjust the bending direction and bending angle of the airbag 8 at the end of the hemostatic part 7. In this embodiment, the angle adjustment mechanism 9 includes an electric wire reel 91 and a traction wire 92. The electric wire reel 91 is located at the top of the hemostatic part 7. Figure 2 As shown, at least three adjustment points are evenly arranged around the cavity wall at the end of the observation cavity 82, and each adjustment point is fixedly connected to one end of a traction line 92, and the other end of the traction line 92 is fixedly connected to the electric wire reel 91. The positioning button 32 controls the electric wire reel 91 through the controller 5 to adjust the retraction and contraction length of the traction line 92, thereby realizing the adjustment of the bending direction and bending angle of the airbag 8.

[0040] In actual operation, the controller 5 adjusts the bending direction of the airbag 8 by controlling at least one electric wire reel 91 to retract the wire. The controller 5 adjusts the bending direction of the airbag 8 by controlling the retracted length of the wire reel 91, such as Figure 3As shown, a group of buttons on the positioning button 32 correspond to different regional divisions of the nasopharynx, so that the airbag 8 can be rotated toward the top wall, bottom wall, left wall, right wall, front wall, and rear wall of the nasopharynx, respectively, and according to the length of the electric wire reel 91 contraction, it can cover the range of the top front wall, top rear wall, top left wall, top right wall, bottom front wall, bottom rear wall, bottom left wall, and bottom right wall. When the hemostatic part 7 is removed from the body 1, the electric wire reel 91 automatically cuts off the power and maintains the current contraction length. Here, it should be noted that in the prior art, there is already an electric wire reel 91 and a controller 5 after the length adjustment. The controller 5 generally adopts a PLC controller 5, which only involves the use of control and does not involve the setting of the program. The PLC controller 5 is a common device, and its specific connection and setting are not described in detail in this invention, that is, this application does not involve the improvement of the controller 5 program, and only the adaptive parameter data adjustment of the specific contraction length is required according to the bending angle of this application, so it is not described in detail here. During operation, after the hemostatic part 7 is sent into the nasal cavity while holding the grip part 3, the positioning button 32 is used to switch to the corresponding nasopharyngeal area, and the specific bleeding point is confirmed through the lens in the airbag 8, which can ensure that inexperienced medical staff can also quickly find the bleeding location and make a correct record in the medical record.

[0041] like Figure 1 As shown, in the present embodiment, a folding bracket 61 and a display screen 62 are further provided at the top of the main body 1. The folding bracket 61 is a hinged L-shaped movable metal plate, and one end of the metal plate is fixed to the top of the main body 1, and the other end is fixedly connected to the back side of the display screen 62. The display screen 62 is movably connected to the main body 1 through the folding bracket 61, so that the display screen 62 can be flipped and adjusted relative to the main body 1 along the hinge axis of the folding bracket 61, ensuring that medical staff can observe the current position of the endoscope and the airbag 8 more quickly and conveniently, and avoid the device in the hand accidentally touching the sensitive area of ​​the nasopharynx when looking up to check the external display multiple times. The display screen 62 is electrically connected to the power switch 31 and is connected to the electronic endoscope signal, thereby ensuring the synchronous display of the display screen 62 and the external display.

[0042] Example 2

[0043] This embodiment provides a specific method for using the nasopharyngeal adaptive compression hemostasis device in Embodiment 1, including the following steps:

[0044] Fix the hemostatic part 7 on the main body 1, turn on the power switch 31, send the electronic endoscope through the endoscope hole 41 and the operation passage 4 into the observation cavity 82 of the hemostatic part 7, and observe through the display screen 62 or the external display at the same time, send the hemostatic part 7 into the nasopharynx through the nasal cavity, and use the controller 5 to control the angle adjustment mechanism 9 through the positioning button 32 of the holding part 3 to adjust the bending direction and bending angle of the observation cavity 82 of the airbag 8. When the airbag 8 is adjusted, it will drive the electronic endoscope lens located in the observation cavity 82 of the airbag 8 to rotate synchronously, so as to confirm the bleeding point.

[0045] After adjusting the direction of the airbag 8 to the bleeding position, select the corresponding hemostasis method according to the bleeding situation: when diffuse bleeding occurs, observe the bleeding area, use a syringe to inflate the airbag 8 through the air valve 81 to achieve overall compression hemostasis; when in addition to diffuse bleeding, there is also a clear bleeding point with a large amount of bleeding, insert the electrocoagulation hemostat through the electrocoagulation hemostasis hole 42, use the electrocoagulation hemostat to perform local electrocoagulation hemostasis on the bleeding point, then remove the electrocoagulation hemostat, and then inflate the airbag 8 to further compress the hemostasis.

[0046] Since compression hemostasis generally takes at least 2 hours, the hemostatic part 7 is removed from the main body 1 after the airbag 8 is inflated, leaving the airbag 8 in the patient's nasal cavity; the hemostatic effect can be ensured before removal through the observation cavity 82, avoiding the need to operate again if the hemostasis is not completed after the airbag 8 is removed, thereby reducing the patient's pain; after ensuring that the hemostasis is completed and before detaching the airbag 8, the hemostatic part 7 and the main body 1 are reconnected, and at this time, the water injection port 43 is ensured to be located above the airbag 8. When taking out the airbag 8, water is injected into the compression side through the water injection port 43 to soften the blood clot, and then the airbag 8 is deflated and taken out using the air valve 81.

[0047] The above description is only a preferred embodiment of the utility model, and is not intended to limit the utility model. It is known to those skilled in the art that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the utility model. In addition, under the guidance of the utility model, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the utility model. Therefore, the utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the utility model.
