Description

TECHNICAL FIELD

[0001] The application relates to the technical field of intubation anesthesia, in particular to a tracheal intubation capable of surface anesthesia. BACKGROUND

[0002] Surface anesthesia refers to applying a strong local anesthetic to the mucosal surface.

[0003] The existing patent (publication number: CN217162864U) discloses a tracheal intubation for implementing surface anesthesia, which comprises a pipe body, a balloon arranged at one end of the pipe body, a gas guide cavity arranged in the pipe body, a first gas guide hole arranged between the balloon and the gas guide cavity, a ball head arranged at one end of the pipe body close to the balloon, a cavity arranged in the ball head, a first gas pump connected to one end of the gas guide cavity, a plurality of second gas guide holes arranged on one side of the outer wall of the ball head, a medicine adding pipe arranged in the pipe body, a channel arranged in the medicine adding pipe, the channel being in communication with the cavity, and a second gas pump connected to one end of the medicine adding pipe. The pipe body, the balloon and the gas guide cavity can perform local surface anesthesia on the affected part, can make the administration of the anesthetic more accurate, can avoid excessive local administration, and solve the problem that the existing surface anesthesia intubation is not accurate in drug administration on the affected part and causes discomfort of the patient due to excessive drug administration at one time.

[0004] The above-mentioned intubation supplies gas to the inside of the channel through the second gas pump, and the gas entering the inside of the cavity blows the anesthetic to the surface of the affected part to complete the surface anesthesia on the affected part. However, in the process of use, the above-mentioned intubation can only spray the inner wall region of the trachea near the balloon, and when a long region of the inner wall of the trachea needs to be anesthetized, the operation of the above-mentioned intubation is relatively cumbersome, and the medical staff need to perform anesthesia while intubating, which is low in efficiency. TECHNICAL FIELD

[0005] In view of the defects of the prior art, the application provides a tracheal intubation capable of surface anesthesia, which has the advantages of automatic spraying and solves the problems in the background art.

[0006] To achieve the above-mentioned purpose, the application provides the following technical scheme: a tracheal intubation capable of surface anesthesia, comprising a guide sleeve and an intubation tube, the top end of the guide sleeve being funnel-shaped, and a fixing assembly being arranged at the middle end of the guide sleeve. The fixing assembly comprises a universal sleeve, the universal sleeve being ball-jointed with the guide sleeve, two symmetrically arranged connecting ribs being fixedly connected to the outer surface of the universal sleeve, an adjusting column being slidingly inserted into one end of each of the two connecting ribs away from each other, a jaw plate being fixedly connected to one end of each of the two adjusting columns away from each other, and a spring being fixedly installed on the inner wall of the connecting rib close to each of the two adjusting columns. The cannula is slidably inserted into the guide sleeve. The bottom end of the cannula is fixedly connected to a connecting section. The bottom end of the connecting section is fixedly connected to a working section. An anesthesia spray ring is fixedly connected to the outer surface of the connecting section. A set of circumferentially arranged spray holes are opened on the outer surface of the anesthesia spray ring. A fixing airbag is fixedly connected to the outer surface of the working section. A set of annular ribs are provided on the outer surface of the fixing airbag.

[0007] Furthermore, a delivery pipe is fixedly connected to the outer surface of the anesthetic spray ring, and a connector is fixedly connected to the other end of the delivery pipe. A one-way valve is installed at the top of the connector, and a connecting pipe is fixedly connected to the middle of the connector.

[0008] The above-described design allows users to easily inject anesthetic via the top of the tap, and the connecting pipe facilitates connection to an external air pump to move the anesthetic.

[0009] Furthermore, an expansion tube is fixedly connected to the outer surface of the fixed airbag, and an air supply airbag is provided at the top end of the expansion tube.

[0010] The above method allows gas to be delivered into the fixed airbag by pressing the air supply airbag, thereby causing the fixed airbag to engage with the inner wall of the trachea.

[0011] Furthermore, two photoelectric switches are fixedly installed at the top of the guide sleeve, and the two photoelectric switches are optically connected. A set of annular scale bars are provided on the outer surface of the insertion tube.

[0012] The above scheme, with the setting of the annular scale bar, makes it easy for users to judge the insertion length of the intubation tube. At the same time, during the insertion process, the annular scale bar can block the photoelectric switch. When blocked, it can drive the external air pump to deliver a certain amount of gas, thereby controlling the quantitative anesthetic to be evenly sprayed on the inner wall of the trachea, achieving the effect of even spraying during the intubation process.

[0013] Furthermore, dental pads are bonded to the ends of the two dental plates that are far apart from each other.

[0014] The above solution, through the setting of the dental pad, can achieve the purpose of protecting the teeth. The bonding of the dental pad can facilitate replacement, and at the same time, it can realize the recycling of the guide sleeve.

[0015] Furthermore, the upper surfaces of both connecting ribs are threaded with fixing nails, and the upper surfaces of both adjusting columns are provided with a set of fixing holes arranged at equal intervals.

[0016] The above scheme, with the setting of fixing nails and fixing holes, allows for fixation after the tooth plate has been adjusted.

[0017] Furthermore, a set of side grooves are formed on the bottom outer surface of the working section.

[0018] The above method prevents secretions or tissue from clogging the end of the cannula and affecting the gas supply.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects: This endotracheal tube, capable of providing surface anesthesia, utilizes a ring-shaped anesthetic spray ring and multi-nozzle design to achieve uniform anesthetic spraying during intubation, covering a wider area of ​​the tracheal mucosa. Combined with the linkage control of a photoelectric switch and a ring-shaped scale bar, it can precisely adjust the anesthetic dosage, triggering a quantitative spray at intervals during insertion, avoiding the risks of uneven anesthesia or overdose caused by traditional single-point spraying. The ring-shaped ribs on the surface of the fixing cuff, after expansion, can form multi-point engagement with the inner wall of the trachea, effectively preventing tube displacement or slippage. Simultaneously, the spring adjustment mechanism of the fixing component can adapt to different oral cavity structures, reducing the risk of oral mucosal damage caused by instrument pressure. The universal sleeve and ball joint structure allow for multi-angle adjustment of the guide sleeve, facilitating medical personnel to adjust the tube insertion angle. The tap and one-way valve design support quick connection to an air pump or syringe, improving operational convenience. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a tracheal intubation tube for surface anesthesia, comprising a guide sleeve 1 and an intubation tube 2. The top of the guide sleeve 1 is funnel-shaped, and a fixing component 3 is provided in the middle of the guide sleeve 1. Two photoelectric switches 101 are fixedly installed at the top of the guide sleeve 1, and the two photoelectric switches 101 are optically connected. A set of annular scale bars 203 is provided on the outer surface of the intubation tube 2. The annular scale bars 203 facilitate the user's judgment of the insertion length of the intubation tube 2. At the same time, during the insertion process, the annular scale bars 203 can block the photoelectric switches 101. When blocked, they can drive an external air pump to deliver a certain amount of gas, thereby controlling the quantitative anesthetic to be evenly sprayed on the inner wall of the trachea, achieving the effect of even spraying during the insertion of the intubation tube 2.

[0024] Please see Figure 1 , Figure 3 and Figure 4 The fixing component 3 includes a universal sleeve 301, which is ball-jointed with the guide sleeve 1. Two symmetrically arranged connecting ribs 302 are fixedly connected to the outer surface of the universal sleeve 301. An adjusting post 303 is slidably inserted into the ends of the two connecting ribs 302 that are far apart from each other. A dental plate 304 is fixedly connected to the ends of the two adjusting posts 303 that are far apart from each other. A spring 305 is fixedly installed on the inner wall of the two adjusting posts 303 and the connecting ribs 302 that are close to each other. With the setting of the spring 305 and the pressure plate, it is easy for medical staff to fix the guide sleeve 1 in the mouth of people with different mouth shapes. A dental pad 306 is glued to the ends of the two dental plates 304 that are far apart from each other. With the setting of the dental pad 306, the purpose of protecting the teeth can be achieved. The bonding of the dental pad 306 can facilitate replacement and also realize the recycling of the guide sleeve 1.

[0025] Please see Figure 1 , Figure 2 and Figure 4The bottom outer surface of the working section 202 is provided with a set of side grooves 2021 to prevent secretions or tissues from blocking the end of the cannula 2 and affecting the air supply. The upper surfaces of the two connecting ribs 302 are threaded with fixing nails 307. The upper surfaces of the two adjusting columns 303 are provided with a set of fixing holes 308 arranged at equal intervals. With the setting of fixing nails 307 and fixing holes 308, the tooth plate 304 can be fixed after adjustment.

[0026] Please see Figure 2 , Figure 5 and Figure 6 The intubation tube 2 is slidably inserted into the guide sleeve 1. The bottom end of the intubation tube 2 is fixedly connected to the connecting section 201, and the bottom end of the connecting section 201 is fixedly connected to the working section 202. An anesthetic spray ring 4 is fixedly connected to the outer surface of the connecting section 201. A set of circumferentially arranged spray holes 401 are opened on the outer surface of the anesthetic spray ring 4. A fixing airbag 5 is fixedly connected to the outer surface of the working section 202. A set of annular ribs 501 are provided on the outer surface of the fixing airbag 5. Through the annular arrangement of the anesthetic spray ring 4, anesthetic can be evenly sprayed onto the inner wall of the trachea. Secondly, through the annular ribs 501 on the surface of the fixing airbag 5, it can expand and lock into the inner wall of the trachea, thereby improving the fixation firmness of the intubation tube 2.

[0027] Please see Figure 1 , Figure 2 and Figure 5 The outer surface of the anesthetic spray ring 4 is fixedly connected to a delivery tube 402. The other end of the delivery tube 402 is fixedly connected to a connector 6. A one-way valve 601 is installed at the top of the connector 6. A connecting tube 602 is fixedly connected to the middle of the connector 6. The top of the connector 6 allows the user to easily inject anesthetic. The connecting tube 602 allows for easy connection to an external air pump, thereby pushing the anesthetic. The outer surface of the fixed airbag 5 is fixedly connected to an expansion tube 502. An air supply airbag 503 is installed at the top of the expansion tube 502. By pressing the air supply airbag 503, gas can be delivered into the fixed airbag 5, thereby causing the fixed airbag 5 to engage with the inner wall of the trachea.

[0028] In this embodiment, an endotracheal tube 2 capable of performing surface anesthesia is designed with an annular anesthesia spray ring 4 and multiple spray holes 401, enabling uniform spraying of anesthetic during intubation and covering a wider area of ​​the tracheal mucosa. Combined with the linkage control of the photoelectric switch 101 and the annular scale bar 203, the anesthetic dosage can be precisely adjusted to trigger quantitative spraying at intervals during insertion, avoiding the risks of uneven or excessive anesthesia caused by traditional single-point spraying. The annular ribs 501 on the surface of the fixing cuff 5 can form multi-point engagement with the tracheal inner wall after expansion, effectively preventing displacement or slippage of the tube 2. Simultaneously, the spring 305 adjustment mechanism of the fixing component 3 can adapt to different oral structures, reducing the risk of oral mucosal damage caused by instrument pressure. The universal sleeve 301 and ball joint structure allow for multi-angle adjustment of the guide sleeve 1, facilitating adjustment of the tube 2 insertion angle by medical personnel. The tap 6 and one-way valve 601 design support quick connection to an air pump or syringe, improving operational convenience.

[0029] The working principle of the above embodiment is as follows: the endotracheal tube 2 is guided into the oral cavity through the funnel-shaped structure at the top of the guide sleeve 1. The universal sleeve 301 of the fixing component 3 and the guide sleeve 1 adopt a ball joint structure, which allows for multi-angle adjustment to adapt to the differences in the patient's oral cavity. Medical staff press the two dental plates 304 on both sides to compress the spring 305 and adapt to the patient's tooth spacing. Then, the position is locked through the fixing pin 307 and the fixing hole 308 on the adjusting post 303. The soft dental pad 306 on the outside of the dental plate 304 can reduce the pressure damage to the teeth and oral mucosa. When the endotracheal tube 2 slides into the airway along the guide sleeve 1, the annular scale bar 203 on its surface moves with the insertion depth. When the scale bar blocks the two sets of light at the top of the guide sleeve 1... When the light path is activated by the electrical switch 101, the external air pump is triggered to push the anesthetic agent to the anesthesia spray ring 4 through the tap 6. The circumferentially arranged spray holes 401 of the anesthesia spray ring 4 spray the anesthetic agent evenly onto the tracheal mucosa surface, covering the area from the glottis to the upper trachea, achieving multi-stage and quantitative anesthesia, avoiding the unevenness of traditional single-point spraying. After the working section 202 at the end of the intubation tube 2 enters the trachea, the medical staff press the air supply cuff 503, and the gas is injected into the fixing cuff 5 through the expansion tube 502. After the cuff expands, the annular ribs 501 on its surface form a multi-point engagement with the inner wall of the trachea to prevent the intubation tube 2 from shifting or slipping. The side groove 2021 at the bottom of the working section 202 can prevent secretions from blocking the lumen and ensure smooth ventilation.
