Description

Technical Field

[0001] This utility model belongs to the field of medical supplies technology, specifically relating to disposable spray-on anesthetic laryngeal lenses. Background Technology

[0002] Because of its deep location and complex physiological structure, the larynx cannot be directly visualized. Therefore, special examination methods are required. A video laryngoscope, a new type of endotracheal intubation aid widely used in clinical practice in recent years, consists of a light source, laryngeal blades, a handle, a camera, a battery, and an LCD screen. During use, the laryngeal blades are placed in the oropharynx. If the patient has a strong gag reflex and cannot cooperate, a disposable laryngeal spray tube is connected to a syringe. The tube is then inserted into the pharynx, and 5 ml of lidocaine is injected to anesthetize the glottis before the examination. This method requires the use of a syringe and a laryngeal spray tube, making the procedure cumbersome and time-consuming. Furthermore, it uses multiple disposable items, including disposable laryngeal blades and a disposable laryngeal spray tube, resulting in resource waste. Chinese invention patent CN111449615A discloses a video laryngoscope for airway surface anesthesia. Its features include: a display screen hinged to the laryngoscope body via a display rotating head; the laryngoscope body includes a laryngoscope handle and a lens handle; a high-pressure bottle and a battery are housed within the laryngoscope handle; a camera assembly is located at the front end of the lens handle, and the camera assembly is electrically connected to the display via a camera cable; a spray button is located on the laryngoscope handle, and the spray button controls the opening and closing of the high-pressure bottle via a linkage lever; the battery is electrically connected to the display; the lens handle is inserted into a disposable spray laryngoscope lens; the disposable spray laryngoscope lens is detachably connected to the lens handle via a lens clip; a nozzle is located at the front end of the disposable spray laryngoscope lens, and the nozzle is airtightly connected to the high-pressure bottle via a tail tube and a delivery tube inside the lens, supplying the liquid medication from the high-pressure bottle for spraying. However, this device requires connection between the disposable laryngoscope lens and the high-pressure bottle located within the laryngoscope handle during use, making the operation cumbersome. Furthermore, the connection between the high-pressure bottle and the laryngoscope lens is not sealed, easily leading to lidocaine contamination and affecting the anesthetic effect. Utility Model Content

[0003] The purpose of this invention is to provide a disposable, sprayable anesthesia laryngoscope lens, which solves the problems of cumbersome operation steps and easy contamination of lidocaine due to non-sealing in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A disposable spray-on anesthetic laryngeal blade includes a hollow light guide block, an arc-shaped baffle plate extending along the concave top surface of the light guide block, and a mounting base. The baffle plate and the light guide block are fixedly connected. The mounting base is fixedly mounted on the first end of the light guide block. A mounting plate is provided on the first end of the light guide block. An anesthetic cavity is fixedly mounted on the mounting plate. A piston is provided inside the anesthetic cavity. A bag is provided inside the anesthetic cavity. The bag stores lidocaine. An elastic element is provided on the inner wall of the first end of the anesthetic cavity. A locking plate is inserted into the anesthetic cavity. The locking plate is located between the elastic element and the piston. A connecting tube is connected to and communicates with the second end of the anesthetic cavity, and a nozzle is provided on the outer wall of the second end of the light guide block, and the nozzle and the connecting tube are in communication. A needle is installed in the second end of the anesthetic cavity.

[0005] Preferably, the number of elastic elements is one or more.

[0006] Preferably, the connecting tube and the light guide block are fixedly connected and extend along the connection between the light guide block and the baffle plate.

[0007] Preferably, the second end of the anesthetic cavity has a through hole, a mounting bracket is fixedly connected inside the through hole, the needle is fixedly mounted on the mounting bracket, and the mounting bracket has several through slots.

[0008] Preferably, a groove is formed on the anesthetic cavity near the first end, the locking plate is inserted into the groove, the first end of the locking plate is bent upward, and the second end of the locking plate passes through the groove and is fixed to the anesthetic cavity.

[0009] Preferably, the first end of the elastic element is fixedly connected to the inner wall of the first end of the anesthetic cavity, and a support plate is fixedly connected to the second end of the elastic element.

[0010] Preferably, a button is provided on the first end of the locking piece, the second end of the locking piece passes through the through groove, a limit block is provided on the second end of the locking piece, and a clearance groove is opened on the locking piece corresponding to the position of the elastic element.

[0011] Preferably, the elastic element is a spring or a sheet spring.

[0012] Preferably, the cross-section of the anesthetic cavity is circular, with the diameter gradually decreasing near the second end.

[0013] Preferably, the nozzle of the spray head is a fan-shaped nozzle.

[0014] Preferably, the second end of the anesthetic cavity extends to the light guide block and is located between the light guide block and the tongue stop.

[0015] Preferably, an adhesive sheet is fixedly disposed on the outer wall of the anesthetic cavity, and an adhesive sheet is fixedly disposed on the nozzle.

[0016] The beneficial effects of this utility model are as follows: By setting an anesthetic cavity on the light guide block and integrating the anesthetic cavity with the laryngoscope blade, no additional anesthesia device is needed when performing laryngoscopy or surgery, simplifying the operation process, improving work efficiency, and the single use also avoids the risk of cross-infection. An elastic element is installed inside the anesthetic chamber. When in use, the elastic element pops out to squeeze the lidocaine inside the anesthetic chamber out of the nozzle to anesthetize the patient's throat. This ensures the safety of lidocaine during transportation and storage. Only when necessary can the doctor release lidocaine by operating the locking plate, avoiding the risk of accidental leakage. The cross-section of the anesthetic cavity is designed to be circular, with the diameter gradually decreasing near the second end. This creates a certain pressure when lidocaine is released, allowing the lidocaine to penetrate the nozzle more effectively and improving the anesthetic efficiency. Attached Figure Description

[0022] Example 1 Disposable spray-on anesthesia laryngoscope, such as Figures 1-3 As shown, the device includes a hollow light guide block 1, an arc-shaped tongue guard 19 extending along the concave top surface of the light guide block 1, and a mounting base 3. The arc-shaped tongue guard 19 is ergonomically designed to reduce irritation and discomfort to the patient's throat. The tongue guard 19 is fixedly connected to the light guide block 1, and the mounting base 3 is fixedly mounted on the first end of the light guide block 1. A mounting plate 6 is provided on the first end of the light guide block 1. An anesthetic cavity 4 is fixedly provided on the mounting plate 6. A piston 5 is provided inside the anesthetic cavity 4. A bag 11 is provided inside the anesthetic cavity 4. The bag 11 and the piston 5 are fixedly connected. The bag 11 stores 6-8 ml of lidocaine, which saves the time of drug preparation. Since some lidocaine will remain in the connecting tube 2, storing more lidocaine ensures the anesthetic effect. An elastic element 7 is provided on the inner wall of the first end of the anesthetic cavity 4. A locking piece 8 is inserted into the anesthetic cavity 4. The locking piece 8 is located between the elastic element 7 and the piston 5. When the locking piece 8 is removed, the elastic element is released and pushes the piston 5 to achieve drug ejection. The second end of the anesthetic cavity 4 is connected to and airtightly communicated with a connecting pipe 2. A nozzle 9 is provided on the outer wall of the second end of the light guide block 1. The nozzle 9 and the connecting pipe 2 are airtightly communicated. Lidocaine is sprayed out from the nozzle 9 at the second end of the light guide block 1 and can spray onto the glottis. A needle 10 is provided in the second end of the anesthetic cavity 4 to puncture the bag body 11 and ensure that lidocaine is released from the bag body 11.

[0023] In use, lidocaine is initially sealed within the bag 11 inside the anesthetic cavity 4. The locking plate 8 is inserted into the groove 12 to lock the elastic element 7. When laryngoscopy is required, the light guide 1 is mounted on the laryngoscope lens via the mounting base 3, with the lens extending to the second end of the light guide 1. The light guide 1 is inserted into the patient's larynx and slowly advanced along the midline to expose the patient's mouth, uvula, pharynx, and epiglottis. The lens can lift the epiglottis between the epiglottis and the base of the tongue to expose the glottis. At this point, the medical staff removes the locking plate 8 from the anesthetic chamber 4, the elastic element 7 is unlocked and released, pushing the piston 5 to move toward the second end of the anesthetic chamber 4. The piston 5 first pushes the bag body 11 to move, so that the needle 10 at the second end of the anesthetic chamber 4 punctures the bag body 11, causing the lidocaine in the bag body 11 to be released. Then the piston 5 continues to squeeze the lidocaine from the connecting tube 2 to the nozzle 9 to spray out, anesthetizing the patient's glottis. After the anesthesia is completed, the patient is examined to avoid the patient's gag reflex being too strong and unable to cooperate.

[0024] As a preferred example of the above embodiments, the number of elastic elements 7 is one or more, so as to achieve different spraying effects. When there is only one elastic element 7, the spraying speed is slower, and when there are multiple elastic elements 7, the spraying speed is faster. When there are multiple elastic elements 7, they are distributed in a ring at equal angles within the anesthetic cavity 4 to ensure uniform thrust.

[0025] As a preferred example of the above embodiments, the elastic element 7 is a spring or a sheet.

[0026] As a preferred example of the above embodiment, the anesthetic cavity 4 has a circular cross-section, and the diameter of the anesthetic cavity 4 gradually decreases near its second end, which helps to create a certain pressure when lidocaine is released, so that lidocaine can be ejected more effectively and the anesthetic efficiency can be improved.

[0027] As a preferred example of the above embodiments, the nozzle of the spray head 9 is a fan-shaped nozzle, and the liquid is sprayed out in an arc shape when spraying, which can cover a wider area and is suitable for throat structures of different sizes and shapes.

[0028] As a preferred example of the above embodiment, the connecting tube 2 and the light guide block 1 are fixedly connected and extend along the connection between the light guide block 1 and the baffle plate 19.

[0029] As a preferred example of the above embodiment, a through hole is opened on the second end of the anesthetic cavity 4, and the needle 10 is fixedly disposed at the edge of the through hole.

[0030] As a preferred example of the above embodiment, a mounting bracket 13 is fixedly connected inside the through hole, and the needle 10 is fixedly mounted on the mounting bracket 13. The mounting bracket 13 has several through slots 14, through which lidocaine passes into the connecting tube 2.

[0031] As a preferred example of the above embodiments, the number of needles 10 gradually increases from top to bottom.

[0032] As a preferred example of the above embodiment, the bag body 11 is made of soft plastic. When punctured by the needle 10, the edge of the hole will be significantly stretched and deformed, resulting in an irregular hole shape, thus ensuring that the liquid flows out.

[0033] As a preferred example of the above embodiment, a groove 12 is provided on the anesthetic cavity 4 near the first end. The locking piece 8 is inserted into the groove 12. The first end of the locking piece 8 is bent upward, and the second end of the locking piece 8 passes through the groove 12 and is fixed to the anesthetic cavity 4. The bent part makes it convenient for the user to remove the locking piece 8.

[0034] As a preferred example of the above embodiment, the anesthetic cavity 4 is provided with a transparent observation window for observing the ejection of lidocaine from the anesthetic cavity 4. When the anesthetic cavity 4 malfunctions and cannot eject the anesthetic, anesthesia is achieved by manual spraying.

[0035] As a preferred example of the above embodiments, the anesthetic cavity 4 is provided with a scale line for observing the amount of lidocaine ejected from the anesthetic cavity 4 to ensure the anesthetic effect.

[0036] Example 2 Example 2 is a preferred example, such as Figure 5 As shown, the first end of the elastic element is fixedly connected to the inner wall of the first end of the anesthetic cavity 4, and a support plate 15 is fixedly connected to the second end of the elastic element. The support plate 15 is in contact with the piston 5 to avoid the elastic element 7 directly squeezing and pushing the piston 5, which would cause uneven thrust.

[0037] Example 3 Example 3 is a preferred example, such as Figure 6As shown, a button 16 is provided on the first end of the locking piece 8, the second end of the locking piece 8 passes through the through groove 12, a limit block 18 is provided on the second end of the locking piece 8, and a relief groove 17 is opened on the locking piece 8 corresponding to the elastic element 7. When in use, pressing the button 16 causes the locking piece 8 to move inward, thereby aligning the relief groove 17 with the elastic element 7, causing the elastic element 7 to release and push the piston 5, making the operation simpler and faster.

[0038] Example 4 Example 4 is a preferred example, such as Figures 7-8 As shown, the second end of the anesthetic cavity 4 extends to the light guide block 1 and is located between the light guide block 1 and the tongue guard 19, which can provide a larger capacity. Laryngoscope blades with different capacities of anesthetic cavities 4 can be selected according to the patient's needs.

[0039] Example 5 Example 5 is a preferred example, such as Figure 9 As shown, the needle 10 is replaced by a syringe 20. The syringe 20 has a hollow interior forming a liquid outlet groove. When in use, after the syringe 20 punctures the bag 11, the lidocaine inside can flow out from the liquid outlet groove, avoiding clogging of the bag 11 and affecting the anesthetic effect.

[0040] Example 6 Example 6 is a preferred example, such as Figure 10 As shown, there are multiple needles 10 distributed along the edge of the through groove, which puncture the bag 1 at multiple locations to avoid clogging the bag 11 and affecting the anesthesia effect.

[0041] Example 7 like Figure 11 As shown, an adhesive sheet 21 is fixedly installed on the outer wall of the anesthetic cavity 4, and an adhesive sheet 21 is fixedly installed on the nozzle 9.

[0042] As a preferred example of the above embodiments, the adhesive patch 21 is a medical pressure-sensitive adhesive patch, and its surface is sealed with PET (polyester film) or PE (polyethylene) release paper.

[0043] In use, the anesthetic cavity 4 is quickly attached to the end of the existing disposable laryngoscope blade, the nozzle 9 is attached to the end of the light guide block 1, and the connecting tube 2 extends along the connection between the outer wall of the light guide plate 1 and the tongue guard 19 to avoid affecting the normal use of the laryngoscope blade, thus completing the installation; during laryngoscopy, the existing laryngoscope blade is inserted into the patient's epiglottis, and the anesthetic is sprayed into the patient's epiglottis through the anesthetic cavity 4.
