Description

Technical Field

[0001] The utility model relates to the technical field of anesthesia, in particular to an anesthetic drug spray device for anesthesia nursing. Background Art

[0002] Anesthesiology nursing, as a professional nursing field, has the main task of providing patients with comprehensive anesthesia-related nursing services during surgery. Such services not only ensure that patients can undergo surgical treatment safely and painlessly, but also greatly improve the smooth progress of the operation. However, achieving this goal is not easy. Anesthesiologists need to use a special tool: an anesthesia nursing anesthetic spray device, so that patients can quickly enter the anesthesia state and create the best surgical conditions for doctors.

[0003] A Chinese patent document with the search announcement number CN211611296U discloses an anesthetic drug spray device for anesthesia care, comprising a lighting lamp, a control box, a power supply, a bracket, a carrier, and a universal seat. One side of the universal seat is spirally connected to one end of a catheter, and the other side of the universal seat is fixedly connected to a drug delivery hole. The other end of the catheter is spirally connected to a nozzle, and the nozzle connects the catheter and the drug tube. A scale is engraved on the outer wall of the drug tube, and a piston is slidably connected to the inner wall of the drug tube. The piston is fixedly connected to one end of a push rod, and the other end of the push rod is fixedly connected to a spring. When the push rod of the utility model is pushed forward, it drives the piston to squeeze the anesthetic drug in the drug tube, and then the anesthetic drug enters the nozzle through the drug delivery hole and is sprayed onto the affected area. Because a universal seat is fixedly connected below the drug delivery hole, the nozzle angle can be adjusted by the universal seat, making it more convenient to control the anesthetic drug. When the screw cap is loosened, the first splint is moved outward under the pressure of the spring, and the bracket moves outward at the same time. However, there are still some problems with the above patents. For example, the patent only solves the problem of using both hands together, which leads to cumbersome operation, inconvenient use, and inaccurate dosage control. However, it cannot solve the problem of manually pushing the device to operate, which makes the device cumbersome to use and fails to completely atomize the anesthetic, resulting in the patient being unable to quickly enter the anesthesia state.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0031] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: an anesthetic drug spray device for anesthesia nursing, comprising a shell 1, the inner wall of the shell 1 is fixedly connected to a drug storage bin 2, the interior of the drug storage bin 2 is fixedly connected to a ventilation pipe 3, the inner wall of the drug storage bin 2 is fixedly connected to a tapered cylinder 7, the interior of the drug storage bin 2 is fixedly connected to a drug inlet pipe 12, the outside of the drug inlet pipe 12 is fixedly connected to the interior of the shell 1, the inner wall of the tapered cylinder 7 is fixedly connected to an air delivery pipe 6, the inner wall of the shell 1 is fixedly connected to a micro air pump 4, the output end of the micro air pump 4 is fixedly connected to the outer wall of the air delivery pipe 6, the input end of the micro air pump 4 is fixedly connected to an air inlet pipe 5, the outer wall of the air inlet pipe 5 is fixedly connected to the interior of the shell 1, the outer wall of the air inlet pipe 5 is fixedly connected to a valve 8, and the outer wall of the drug storage bin 2 is provided with a screening component;

[0032] Specifically, the anesthetic to be used is sent into the interior of the medicine storage bin 2 through the medicine inlet pipe 12. The medicine storage bin 2 is responsible for storing the anesthetic to ensure a stable supply of anesthetic gas in subsequent operations. At the same time, the air inlet pipe 5 is connected to the oxygen pipeline to ensure that there is enough oxygen supply during the anesthesia process. Next, the valve 8 is opened and the micro air pump 4 is started at the same time. The function of the micro air pump 4 is to extract oxygen from the oxygen pipeline and send it into the interior of the conical cylinder 7 through the air delivery pipe 6. The design of the conical cylinder 7 enables the gas to produce an acceleration effect inside, thereby forming a high-speed airflow. The generation of high-speed airflow not only helps to eject the anesthetic, but also drives the anesthetic inside the medicine storage bin 2 to The internal movement of the drug delivery tube 9 realizes the automatic delivery of anesthetics without manual intervention, thereby reducing the risk of operational errors. In addition, the gas is sent into the interior of the drug storage bin 2 through the ventilation tube 3, which can prevent the formation of negative pressure inside the drug storage bin 2 and prevent the anesthetic from being unable to flow out with the gas ejected from the gas delivery tube 6. This design ensures that the anesthetic can be stably and fully automatically ejected, thereby improving the anesthetic effect. During the entire operation, the equipment will operate automatically without manual push. This design avoids the instability that may be caused by manual operation, so that the anesthetic mist can be ejected evenly, so that the patient can quickly enter the anesthesia state, creating good conditions for surgery.

[0033] Reference Figure 2 The screening component includes a drug delivery tube 9, the outer wall of the drug delivery tube 9 is fixedly connected to the outer wall of the drug storage bin 2, and the inner wall of the drug delivery tube 9 is fixedly connected to a barrier net 10; the interior of the drug delivery tube 9 is fixedly connected to a return pipe 11, and the bottom end of the return pipe 11 is fixedly connected to the interior of the drug storage bin 2;

[0034] Specifically, the anesthetic mist is transported upward through the drug delivery tube 9. When the drug delivery tube 9 passes through the barrier net 10, the barrier net 10 serves to intercept larger anesthetic particles in the aerosol. These larger particles of anesthetic may cause discomfort to the patient or even cause respiratory complications. Therefore, the effective filtration of the barrier net 10 makes the anesthetic particles in the aerosol smaller, which is beneficial to the patient's comfort. At the same time, the system is also equipped with a reflux pipe 11 on one side, which returns the intercepted larger anesthetic particles to the interior of the drug storage bin 2. In this way, not only can the accurate dosage of the anesthetic be ensured and waste can be avoided, but also larger anesthetic particles can be prevented from having adverse effects on the patient during the drug delivery process.

[0035] Reference Figure 3-5The top of the drug delivery tube 9 is fixedly connected to a connecting tube 13, the outer wall of the connecting tube 13 is fixedly connected to the inside of the housing 1, and the outer wall of the connecting tube 13 is fixedly connected to a fixing ring 14; the outer wall of the fixing ring 14 is fixedly connected to a fixing block 15, the inner part of the fixing block 15 is rotatably connected to a connecting shaft 16, and the outer wall of the connecting shaft 16 is fixedly connected to a splint 17 and a splint 2 18; the inner wall of the splint 2 18 is fixedly connected to a telescopic rod 25, the outer wall of the telescopic rod 25 is fixedly connected to a buffer plate 24, and the outer wall of the telescopic rod 25 is provided with a spring 26; One end of the spring 26 is fixedly connected to the outer wall of the second splint 18, and the other end of the spring 26 is fixedly connected to the outer wall of the buffer plate 24. The outer wall of the second splint 18 is fixedly connected to the connecting block 19, and the outer wall of the first splint 17 is fixedly connected to the connecting block 20; the inner wall of the connecting block 20 is slidably connected to the limit plate 23, the outer wall of the limit plate 23 is fixedly connected to the push plate 22, the outer wall of the connecting block 19 is fixedly connected to the buckle 21, the outer wall of the buckle 21 is set on the inner wall of the connecting block 20, and the outer wall of the push plate 22 is set on the outer wall of the buckle 21;

[0036] The second clamping plate 21 is then clamped on the outer side of the connecting tube 13, and the second clamping plate 17 is clamped on the outer side of the connecting tube 13. The next step is to restrict the clamping plate 17 and the second clamping plate 18 by the fixing ring 14, the fixing block 15 and the connecting shaft 16. This design makes the connecting block 19 and the connecting block 20 only move on one side of the fixing block 15, thereby enhancing the stability of the nozzle. During operation, the buffer plate 24 plays a key buffering role. It is located on the clamping plate 17. The interior of the second splint 18 can effectively clamp the nozzle. At the same time, the spring 26 is located between the buffer plate 24 and the splint 17 and the second splint 18, which plays a buffering role to prevent the nozzle from accidentally falling off during use. Finally, the telescopic rod 25 limits the position of the spring 26 to prevent the spring 26 from shifting during use. This design ensures that the nozzle can be stably clamped and facilitates the rapid replacement of the nozzle. In short, the design of this disposable nozzle changer fully considers the convenience of use and the stability of the nozzle. Through the coordinated action of the push plate 22, the buckle 21, the connecting block 19, the connecting block 20, the splint 17, the splint 218, the fixing ring 14, the fixing block 15, the connecting shaft 16, the buffer plate 24, the spring 26 and the telescopic rod 25, the nozzle can be replaced quickly and easily, and the efficiency of use is improved. At the same time, the design of the buffer plate 24 and the spring 26 enhances the stability of the nozzle, avoids accidental falling off during use, and ensures the safety of the user.

[0037] Working principle: When it is necessary to use an anesthetic drug spray device for anesthesia nursing, the anesthetic to be used is sent into the interior of the drug storage bin 2 through the drug inlet pipe 12, and the air inlet pipe 5 is connected to the oxygen pipeline. The valve 8 is opened and the micro air pump 4 is started. The oxygen is extracted through the micro air pump 4 and sent into the interior of the conical cylinder 7 through the air delivery pipe 6. The gas is accelerated to be discharged in the interior of the conical cylinder 7 through the air delivery pipe 6 and the conical cylinder 7. At the same time, the anesthetic in the drug storage bin 2 is driven to move to the interior of the drug delivery pipe 9 by the high-speed airflow, and the gas is sent into the interior of the drug storage bin 2 through the ventilation pipe 3 to prevent the storage of drugs. Negative pressure is formed inside the bin 2, which prevents the anesthetic from flowing out along with the gas ejected from the gas pipe 6. As a result, there is no need to manually push the device to operate, and the device can operate on its own, preventing manual operation of the device from causing uneven spraying of the anesthetic mist, which prevents the patient from quickly entering an anesthetized state, and achieving the effect of fully automatic spraying of the anesthetic mist. The anesthetic mist is transported upward through the drug delivery tube 9. When passing through the barrier net 10, the larger anesthetic particles in the mist are intercepted by the barrier net 10. At the same time, the anesthetic is returned to the interior of the drug storage bin 2 through the reflux pipe 11 on the side of the drug delivery tube 9 to prevent the larger anesthetic particles from causing discomfort to the patient. After use, press the push plate 22, and push the buckle 21 to move to the middle through the push plate 22, so that the connecting block 19 connected by the buckle 21 can be pulled out from the inside of the connecting block 20, so that the splint 17 and the splint 2 18 can be removed from the connecting tube 13, so that the disposable nozzle can be removed from the connecting tube 13. When using, install a new nozzle on the connecting tube 13, and then clamp the splint 17 and the splint 2 18 on the outside of the connecting tube 13, and at the same time, use the splint 17 and the splint 2 18 to preliminarily clamp and fix the nozzle and the connecting tube 13, and then use the fixing ring 14, the fixing block 15 and the connecting The shaft 16 restricts the splint 17 and the splint 2 18, so that the connecting block 19 and the connecting block 2 20 can only move on one side of the fixed block 15. At the same time, the buffer plate 24 inside the splint 17 and the splint 2 18 is used to clamp the nozzle for a second time, so that the nozzle is fixed more firmly. At the same time, the spring 26 is used to buffer the buffer plate 24 and the splints 17 and 18 to prevent the nozzle from falling off during use. At the same time, the position of the spring 26 is limited by the telescopic rod 25 to prevent the spring 26 from shifting during use, thereby achieving the effect of stably clamping the nozzle and facilitating and quickly replacing the nozzle.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
