Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to an adjustable spray device. Background Art

[0002] Anesthetics refer to drugs or non-drug methods that cause temporary and reversible loss of consciousness and pain in the body or part of the body. They are mostly used in surgery or the treatment of certain diseases. Types of anesthetics include inhalation anesthetics, intravenous anesthetics and animal compound anesthetic preparations. Their range of action can be divided into general anesthetics and local anesthetics.

[0003] In clinical anesthesia, when intubation is required for throat surgery and airway obstruction caused by various reasons, it is essential to give sufficient surface anesthesia to fully suppress the throat reflex, fully expose the throat, and smoothly perform the endotracheal intubation operation. An anesthesia spray device is required. However, conventional anesthetic agent injection mostly uses a syringe through an atomizing nozzle, which not only has poor atomization effect and is easy to drip, which expands the anesthesia effect, but also makes it difficult to control the injection amount of the agent, affecting the anesthesia effect. In view of the existing problems, an adjustable spray device is proposed. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art that conventional anesthetic agent spraying atomization effect is poor, easy to drip, and the agent spraying amount is difficult to control, and proposes an adjustable spray device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An adjustable spray device is designed, comprising a shell, the two ends of the shell are open, a base is fixedly installed at the bottom of the shell, an airbag is installed on the base, a top plate is fixedly installed on the upper surface of the airbag, a spray pipe is installed at the lower end of the shell, the upper end of the spray pipe passes through the shell and the base and is connected to the inside of the airbag, a nozzle is installed at the lower end of the spray pipe, and telescopic rods are installed in an array between the two ends of the bottom of the shell and the two ends of the top plate.

[0007] Preferably, a heating wire is electrically connected and installed inside the base.

[0008] Preferably, an atomizing hood is threadedly and tightly mounted on the upper surface of the shell, an input tube is connected and fixedly mounted on the upper end of the airbag, the input tube slides through the top plate and the shell, a top plug is fixedly mounted on the upper end of the input tube, a medicine passage hole is provided in a circular array on the upper end of the input tube, and a medicine bottle is threadedly connected to the upper end of the atomizing hood.

[0009] Preferably, both sides of the atomizing hood are connected and fixedly installed with an air inlet pipe, a filter sheet is fixedly placed in an array inside the air inlet pipe, a water-blocking filter element and a one-way valve are fixedly installed on one end of the air inlet pipe close to the atomizing hood, a one-way valve is installed between the medicine bottle and the atomizing hood, and a one-way valve is installed in the spray pipe.

[0010] Preferably, a spring is sleeved on the outside of the input tube, and the upper and lower ends of the spring are fixedly connected to the top plug and the shell respectively.

[0011] Preferably, a accommodating frame is fixedly mounted on the outer side of the atomizing cover, and the accommodating frame is arranged to fit in correspondence with the outer side of the lower part of the medicine bottle.

[0012] Preferably, a handle is fixedly mounted on one side of the shell.

[0013] The utility model provides an adjustable spray device, which has the following beneficial effects:

[0014] 1. By installing the airbag inside the shell, when the top plate above is pressed, the airbag below is squeezed, so that the medicine inside the airbag can be sprayed out through the spray tube. The size of the airbag is reasonable. When the telescopic rod assists in controlling the squeezing amplitude of the top plate to descend, the amount of medicine sprayed can be controlled relatively accurately, so that in actual operation, it is convenient to adjust the injection of anesthetic agents according to the different ages and physiques of personnel, and reduce the damage to the personnel's body on the basis of satisfying the anesthesia effect during surgery.

[0015] 2. When the airbag is squeezed, the top plug is close to the upper surface of the shell. At this time, the telescopic rod is controlled to extend so that the air inlet pipe inputs filtered air into the airbag. At this time, the airbag inhales and expands, driving the input pipe and the top plug to rise. Due to the gap between the top plug and the atomization hood, the medicine in the medicine bottle enters the atomization hood and mixes with the air to form atomized medicine, which finally enters the airbag through the medicine hole at the upper end of the input pipe. Compared with the traditional anesthetic agent injection device, not only the medicine is atomized twice, making the sprayed medicine more delicate and convenient for rapid absorption by the human body, but also the whole device is isolated from the outside world from gas inhalation to medicine atomization and spraying, which is safer and more hygienic to avoid bacterial infection.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Example 1

[0023] Reference Figure 1-4 , an adjustable spray device, including a shell 1, both ends of the shell 1 are open, which is convenient for the lifting and lowering of the two ends of the top plate 4, a base 2 is fixedly installed at the bottom of the shell 1, the base 2 is used to support and accommodate the air bag 3, to prevent the air bag 3 from being deformed and offset after being squeezed, and a heating wire is electrically connected and installed in the base 2, the heating wire can heat the atomized medicine in the air bag 3, to avoid spraying into the patient's throat, and causing discomfort or irritation to the patient due to the cold medicine, the air bag 3 is installed on the base 2, the air bag 3 is made of flexible silicone material, is safe and non-toxic, and can be compressed and deformed, the top plate 4 is fixedly installed on the upper surface of the air bag 3, and the top plate 4 is fully fitted with the upper surface of the air bag 3 , so that when the top plate 4 is pressed down, the downward pressure on the airbag 3 as a whole is always uniform and spreads throughout the spraying of the internal atomized medicine. A spray tube 6 is installed at the lower end of the shell 1. The upper end of the spray tube 6 passes through the shell 1 and the base 2 and is connected to the inside of the airbag 3. A nozzle is installed at the lower end of the spray tube 6. The nozzle is a disposable setting, which is easy to replace and safer and more hygienic. The setting of the spray tube 6 can extend the range of medicine injection, so that it can be inserted into the patient's throat for drug injection, directly reaching the position, with good accurate coverage and fast onset of medicine. Telescopic rods 5 are installed in an array connection between the two ends of the bottom of the shell 1 and the two ends of the top plate 4. The telescopic rods 5 are electric push rods and can be controlled synchronously.

[0024] By installing the airbag 3 inside the shell 1, when the top plate 4 above is pressed, the airbag 3 below is squeezed, so that the medicine inside the airbag 3 can be sprayed out through the spray tube 6. The size of the airbag 3 is reasonable. When the telescopic rod 5 assists in controlling the squeezing amplitude of the top plate 4 to descend, the amount of medicine sprayed can be controlled relatively accurately, so that in actual operation, it is convenient to adjust the injection of anesthetic agents according to the different ages and physical conditions of personnel, thereby reducing damage to the personnel's body while satisfying the anesthesia effect during surgery.

[0025] A handle 15 is fixedly mounted on one side of the housing 1, and the arrangement of the handle 15 facilitates holding the device.

[0026] Example 2

[0027] According to Example 1, the medicine in Example 1 can only be supplied once, which is inconvenient. Figure 1-4 , as another preferred embodiment of the utility model, based on embodiment 1;

[0028] The upper surface of the shell 1 is threadedly and sealed with an atomizing hood 7, the upper end of the airbag 3 is connected and fixedly installed with an input tube 8, the input tube 8 slides through the top plate 4 and the shell 1, the upper end of the input tube 8 is fixedly installed with a top plug 9, the outer surface of the top plug 9 is wrapped with a silicone sealing pad to make the sealing better, the upper end of the input tube 8 is provided with a circumferential array of medicine holes, the upper end of the atomizing hood 7 is connected with a medicine bottle 11 through a thread, and the medicine bottle 11 contains an anesthetic agent, the two sides of the atomizing hood 7 are connected and fixedly installed with an air inlet pipe 13, and a filter sheet 14 is fixedly placed in an array in the air inlet pipe 13. A water-blocking filter element and a one-way valve are fixedly installed near one end of the atomizing hood 7. The water-blocking filter element prevents the medicine from entering the air inlet pipe 13. The one-way valve on the air inlet pipe 13 is closed when the medicine is atomized and sprayed, and is opened when the medicine enters the air bag 3 from the medicine bottle 11. A one-way valve is installed between the medicine bottle 11 and the atomizing hood 7. This one-way valve is opened when the medicine enters the air bag 3 from the medicine bottle 11, and is closed when the medicine is atomized and sprayed. A one-way valve is installed in the spray tube 6. This one-way valve is closed when the medicine enters the air bag 3 from the medicine bottle 11, and is opened when the medicine is atomized and sprayed.

[0029] A spring 10 is sleeved on the outside of the input tube 8, and the upper and lower ends of the spring 10 are fixedly connected to the top plug 9 and the housing 1 respectively. The setting of the spring 10 assists the inflation and recovery of the airbag 3. A receiving frame 12 is fixedly installed on the outside of the atomizing cover 7, and the receiving frame 12 is correspondingly fitted to the outer side of the lower part of the medicine bottle 11.

[0030] When the airbag 3 is squeezed, the top plug 9 is located close to the upper surface of the shell 1. At this time, the telescopic rod 5 is controlled to extend. At this time, since the air inlet pipe 13 is close to one end of the atomizing hood 7, a one-way valve is installed between the medicine bottle 11 and the atomizing hood 7, and in the spray tube 6, the air inlet pipe 13 inputs filtered air into the airbag 3. At this time, the airbag 3 inhales and expands, driving the input pipe 8 and the top plug 9 to rise. Due to the gap between the top plug 9 and the atomizing hood 7, and the negative pressure suction force inside the airbag 3, the medicine in the medicine bottle 11 enters the atomizing hood 7, mixes with the air to form atomized medicine, and finally enters the airbag 3 through the medicine hole at the upper end of the input pipe 8. Compared with the traditional anesthetic agent injection device, not only the medicine is atomized twice, making the sprayed medicine more delicate and convenient for rapid absorption by the human body, but also the device as a whole is isolated from the outside world from gas inhalation to medicine atomization and spraying, which is safer and more hygienic, and avoids bacterial infection.

[0031] Working principle: hold the handle 15, push the spray tube 6 deep into the patient's mouth and aim the nozzle at the patient's throat, then control the telescopic rod 5 to retract, drive the top plate 4 to descend, squeeze the airbag 3, and make the internal medicine spray out through the spray tube 6. When the airbag 3 is squeezed, the top plug 9 is close to the upper surface of the shell 1. At this time, control the telescopic rod 5 to extend. At this time, since the air inlet pipe 13 is close to one end of the atomization hood 7, the one-way valve is installed between the medicine bottle 11 and the atomization hood 7, and in the spray tube 6, the air inlet pipe 13 inputs filtered air into the airbag 3. At this time, the airbag 3 inhales and expands, driving the input pipe 8 and the top plug 9 to rise. Since there is a gap between the top plug 9 and the atomization hood 7, and under the action of the negative pressure suction inside the airbag 3, the medicine in the medicine bottle 11 enters the atomization hood 7, mixes with the air to form an atomized medicine, and finally enters the airbag 3 through the medicine hole at the upper end of the input pipe 8, ready for the next injection.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
