Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical atomization devices, in particular to a gas flow atomizer applicable to patients in a supine position. BACKGROUND

[0002] In the medical field, atomization therapy is a common method of drug delivery, and is widely used in the treatment of respiratory diseases. Traditional atomization machines require a public atomization tube and a separate mask (or mouthpiece) for use. When using, a separate mask (or mouthpiece) is issued to the patient, and the mask (or mouthpiece) is discarded after use. The atomization machine and the public atomization tube need to be strictly disinfected to avoid the risk of cross infection. In contrast, disposable gas flow atomizers are gradually favored due to their simplicity and cost-effectiveness.

[0003] The disposable gas flow atomizer mainly comprises a body, a mask, a connecting tube and a fixing belt. The body includes a cup body and an atomization core. The cup body has a connecting head for connecting the mask. The atomization core has a cover body integrally formed on the top, and the atomization core is integrally buckled in the cup body through the cover body. The cup body has a conical air inlet nozzle protruding into the cup. The bottom of the air inlet nozzle is connected with an air inlet tube, and the air inlet tube extends to the bottom of the cup body. The atomization core has a conical connecting cap integrally formed on the bottom. The top of the connecting cap is provided with an atomization outlet. The inner wall of the connecting cap is provided with a medicine suction groove in communication with the atomization outlet. The medicine suction groove is provided with a flow dividing plate above. The outer wall of the upper part of the atomization core and the inner wall of the cup body form an atomization outlet channel for the medicine mist to flow to the connecting head.

[0004] In use, the mask is connected to the connecting head of the cup body, one end of the connecting tube is connected to the air inlet tube at the bottom of the cup body, and the other end is connected to the atomization machine. The medicine liquid is poured into the cup body, and then the atomization core is buckled. The airflow with pressure enters the connecting cap from the air inlet nozzle, and is sprayed out from the atomization outlet at high speed. The medicine liquid is sucked into the connecting cap from the medicine suction groove under the action of the airflow, and is atomized into medicine mist under the action of the airflow and sprayed out from the atomization outlet. The sprayed medicine mist is divided into two streams by the flow dividing plate, and then flows to the connecting head through the atomization outlet channel between the atomization core and the cup body, and finally flows into the mask for the patient to inhale. The atomizer is small in size, and the fixing belt can be fixed on the mask during use, so that the whole atomizer can be worn on the patient's face. After use, the whole atomizer can be discarded, and the subsequent disinfection process is saved.

[0005] However, this atomizer has certain limitations in actual application, especially when it is used for patients in a supine position during anesthesia, such as patients in a period of anesthesia after anesthesia. When the atomizer is worn on the patient's face, the body of the atomizer is tilted to the horizontal state, and the medicine liquid and the atomization core are also tilted to the horizontal state, which will cause the medicine liquid to be unable to collect at the air inlet nozzle, and most of the medicine liquid will be unable to be sucked into the connecting cap, affecting the normal atomization work of the atomizer, and limiting the use of the atomizer in patients in a supine position. SUMMARY

[0006] The present application aims to provide an airflow atomizer applicable to supine position to solve the problem that the existing disposable airflow atomizer is limited in use for patients in supine position.

[0007] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0008] An airflow atomizer applicable to supine position, comprising a cup body, an atomizing core, a mask, a connecting pipe and a fixing belt, the fixing belt being capable of being fixed on the mask, the cup body being provided with a connecting head in communication therewith, the mask being detachably connected with the connecting head, the atomizing core being provided at the top thereof with a cover body, the atomizing core being capable of being buckled in the cup body through the cover body, the bottom of the cup body being protruded into the cup body to form an air inlet nozzle, the air inlet nozzle being provided at the bottom end thereof with an air inlet pipe in communication therewith, the connecting pipe being detachably connected with the air inlet pipe, the atomizing core comprising a connecting rod at the upper portion thereof and an atomizing rod at the lower portion thereof, the connecting rod being rotatably connected with the atomizing rod, the atomizing rod being provided at the bottom thereof with a connecting cap capable of being tightly buckled on the air inlet nozzle, the connecting cap being provided at the top end thereof with a mist outlet, the inner wall of the connecting cap being provided with a medicine suction groove in communication with the mist outlet, the mist outlet being provided above the connecting cap with a flow distribution plate, the flow distribution plate being provided at the left and right sides thereof with guide plates perpendicular thereto, the two guide plates being protruded from the left and right sides of the flow distribution plate at the two ends thereof, the connecting rod and the cup body forming a mist outlet channel for the flow of medicine mist, and the cup body being provided at the connecting position of the atomizing rod and the connecting rod with a transverse corrugated pipe.

[0009] Preferably, as an improvement, the bottom end of the transverse corrugated pipe is communicated with a vertical corrugated pipe, the connecting position of the transverse corrugated pipe and the vertical corrugated pipe is provided with a support ring, the support ring comprising a connecting sleeve and a plurality of annular support plates, the atomizing rod being capable of being inserted into the connecting sleeve, the support plates being connected with the connecting sleeve through an extension mechanism, the extension mechanism being provided with a locking assembly, the bottom of the vertical corrugated pipe being sealed with a bottom plate, the bottom plate being fixed with a tray having the same area as the bottom plate at the bottom thereof, the bottom plate comprising a fixed plate at the middle portion thereof and a plurality of movable plates provided at the periphery of the fixed plate, the air inlet nozzle being provided on the fixed plate, the bottom end of the vertical corrugated pipe being fixedly connected with the edges of the movable plates, the movable plates and the fixed plate jointly forming a circular bottom plate, the movable plates being connected with each other and the fixed plate through elastic cloth, and the elastic cloth being flush with the surfaces of the movable plates and the fixed plate.

[0010] Preferably, as an improvement, the extension mechanism comprises a sliding sleeve and a sliding rod, one end of the sliding sleeve being fixed on the connecting sleeve, one end of the sliding rod being fixed on the support plate, the other end of the sliding rod being fixed with a piston, the piston being slidably connected in the sliding sleeve, and the piston and the free end of the sliding sleeve being connected with a pre-tightening spring.

[0011] Preferably, as an improvement, the locking assembly comprises at least two symmetrically arranged locking rods, the inner wall of the sleeve is provided with a clearance groove for the locking rods, one end of the locking rod is hinged in the clearance groove and a return spring is connected between the locking rod and the clearance groove, the locking rod is inclined towards the inside of the sleeve in a free state, and the side of the piston facing the locking rod is integrally formed as a conical head.

[0012] Preferably, as an improvement, a mark ring is arranged on the outer wall of the cup body corresponding to the position of the support ring.

[0013] The principles and advantages of the present scheme are:

[0014] 1. In the present scheme, the atomizing core is divided into a connecting rod at the upper part and an atomizing rod, and a transverse bellows is arranged on the cup body corresponding to the connecting part of the connecting rod and the atomizing rod. This design allows the cup body and the atomizing core to be bent from the transverse bellows. When the atomizer is used for a patient in a supine position, the patient wears the atomizer, and the atomizer body and the atomizing core are bent downward from the transverse bellows to a vertical state, so that the part of the cup body containing the liquid medicine and the atomizing rod part at the bottom of the atomizing core are always in a vertical state, the liquid medicine can always be in contact with the atomizing rod, the atomizer can normally atomize, and the atomizer can be normally used, effectively solving the problem that the existing disposable airflow atomizer is not suitable for patients in a supine position.

[0015] The cup body is bent in this way, the upper half of the cup body structure remains unchanged, the atomizer can still be worn on the patient's face, and the use is convenient. The inventor has also tried to replace the connecting head between the cup body and the mask with a flexible tube, but this design causes the cup body to be unable to be worn on the patient's face, and the cup body needs to be placed on a stable table surface, such as a bedside table. However, directly placing the cup body on the bedside table may cause the cup body to be tilted and the liquid medicine to be spilled, which may interrupt the atomization, and is not convenient in actual use.

[0016] 2. Further, a vertical bellows is additionally arranged below the transverse bellows, a support ring with a contractible radius is arranged at the connecting part of the transverse bellows and the vertical bellows, and the bottom plate is divided into a fixed plate at the middle part and a movable plate at the periphery. This design utilizes the variable-diameter feature of the vertical bellows, so that when the support ring is pressed to reduce its radius, the upper end of the vertical bellows can be inwardly contracted, thereby driving the movable plate fixedly connected to the bottom end of the vertical bellows to be upwardly tilted. After being upwardly tilted, the movable plate at the periphery is locked by the locking assembly, and after being upwardly tilted, the movable plate at the periphery can collect the liquid medicine at the bottom of the cup body to the air inlet nozzle, so that the liquid medicine can be fully sucked into the connecting cap for atomization, the liquid medicine can be fully utilized, and the waste of the liquid medicine is reduced.

[0017] In addition, when the support ring is squeezed to deform the cup body, the movable plates are separated, the shape of the cup body is changed and locked by the locking assembly, so that the cup body becomes a scrap, and the situation that the cup body is illegally recycled can be avoided.

[0018] In summary, the deformable cup body of the present application can collect the tail medicine by squeezing the support ring to shrink and drive the bottom of the cup body to deform upward when the liquid medicine is almost atomized, and can also scrap the cup body to avoid illegal recycling.

[0019] 3. In addition, the support ring is arranged at the connection between the horizontal corrugated pipe and the vertical corrugated pipe, which can support the horizontal corrugated pipe and the vertical corrugated pipe to maintain the shape during normal use. Furthermore, the support ring can provide a holding part for the operator when bending the cup body, and the force can be better applied by holding the support ring than directly holding the hollow horizontal corrugated pipe or vertical corrugated pipe.

[0020] 4. For the structure of the support ring, a sliding sleeve and a sliding rod are arranged between the support plate and the connecting sleeve, and a pre-tightening spring is arranged in the sliding sleeve. Such design can only deform the pre-tightening spring to force the support ring to shrink inward when the force is sufficient, and the support ring can maintain a stable state when the force is insufficient or small, to ensure the stability of the shape of the cup body.

[0021] 5. For the locking assembly, when the piston on the sliding rod moves to the locking rod, the locking rod is forced to rotate outward of the sliding sleeve to avoid the piston, and after the piston passes, the locking rod is reset to block behind the piston, thereby realizing the locking of the sliding rod. Such design can lock the sliding rod to maintain the compressed state, and further maintain the deformed state of the cup body to complete the scrapping of the cup body.

[0039] A method for using the airflow atomizer applicable to the supine position is as follows:

[0040] The embodiment takes the patient in the supine position as an example to introduce the specific use method, which is as follows:

[0041] 1. Connect one end of the connecting pipe to the air inlet pipe at the bottom of the cup body 1, and connect the other end of the connecting pipe to the external atomizer;

[0042] 2. Connect the face mask 5 to the connecting head 14, and bundle and fix the ends of the fixing belt in the fixing holes on the two sides of the face mask 5 respectively;

[0043] 3, Add the appropriate amount of liquid medicine in the cup 1, liquid medicine does not exceed the vertical corrugated tube, the atomizing core 2 into the cup 1, so that the connection cap 27 above the atomizing rod 22 part of the plug-in connection to the connecting sleeve 3, while the connection cap 27 buckle to the air inlet nozzle 15, then cover tightly cover 28;

[0044] 4, through the fixed belt to wear the atomizer on the patient's face, hold the support ring and bend the cup 1, so that the vertical corrugated tube part 13 from the horizontal corrugated tube at the bottom of the cup 1 is bent into a vertical state, the atomizing rod 22 on the atomizing core 2 in the cup 1 with the bending of the cup 1 also rotates to the vertical state. Open the atomizer, with the airflow from the air inlet nozzle 15 blows in, the airflow is accelerated after the conical air inlet nozzle 15, high speed from the mist outlet 25, the liquid medicine is sucked into the connecting cap 27 under the action of high-speed airflow, and atomized into the drug mist under the action of airflow from the mist outlet 25. The ejected mist is divided into two streams under the action of the flow divider 24 and the flow guide plate 23, the fine mist flows into the face shield 5 from the outside of the mist outlet channel around the connecting rod 20 on both sides to be inhaled by the patient, the larger particles of the drug mist drops down to be re-atomized.

[0045] By bending the lower part of the cup 1 into a vertical state, the patient lying down can wear the atomizer of the present application on the face, the liquid medicine in the cup 1 and the atomizing rod 22 can still maintain a vertical state, so that the liquid medicine in the atomizer can still fully contact with the atomizing rod 22 when the patient is in a lying position, so that the liquid medicine can be fully atomized, and the atomizer can be used normally in a lying position.

[0046] 5, when the drug is quickly atomized, hold the support ring and squeeze the support ring inwardly, force the pre-tightening spring 37 to stretch so that the sliding rod 31 slides towards the sliding sleeve 30, continue to squeeze after feeling that the piston 36 is blocked by the locking rod 38, the piston 36 forces the locking rod 38 to rotate outwardly to the avoidance groove 34 to let the piston 36 pass, and the resistance disappears, at this time the piston 36 completely slides through the locking rod 38, and the locking rod 38 is blocked outside the piston 36, at this time pulling the sliding rod 31 outwardly will be resisted by the locking rod 38 again, at this time the support ring can be released. At this time the piston 36 slides to the locking position, in this process the sliding rod 31 pulls the upper end of the vertical corrugated tube part 13 to contract horizontally inwardly, the bottom end of the vertical corrugated tube part 13 connected to the movable plate 41 is pulled to be upturned and locked in this state by the locking rod 38, the upturned movable plate 41 can collect the tail medicine at the bottom of the cup 1 to the air inlet nozzle 15, so that the liquid medicine can be as much as possible to be adsorbed into the connecting cap 27 for atomization, reducing the waste of liquid medicine, due to the existence of the elastic cloth, the bottom plate can still contain liquid medicine after the movable plate 41 is upturned.

[0047] After the atomization is completed, the atomizer can be directly discarded. At this time, due to the upwarping of the outer circle of the bottom plate of the cup body 1, the top end of the vertical bellows part 13 is also inwardly contracted, the shape of the entire cup body 1 is destroyed, and is locked and kept by the locking rod 38, and the locking rod 38 can be in contact with the pre-tightening spring 37 after resetting, further improving the locking effect on the piston 36. Therefore, the piston 36 is clamped at the locking rod 38, so that the cup body 1 cannot be restored, so that the atomizer becomes a scrap product, and the situation that the atomizer may be illegally recycled can be effectively avoided.

[0048] Embodiment 2:

[0049] As shown in Figure 9 and Figure 10 The difference between this embodiment and embodiment 1 is that two notches 39 are opened on the locking rod 38. When the piston 36 slides to the left side of the locking rod 38, the piston 36 slides rightward to abut against the locking rod 38 under the action of the pre-tightening spring 37. At this time, the resetting force of the piston 36 can drive the free end part of the locking rod 37 to bend from the notch 39 to the inside of the sliding sleeve, that is, Figure 9 As shown in the state, the bent part of the locking rod 38 can better contact the pre-tightening spring 37, further improving the locking effect.

[0050] Embodiment 3:

[0051] The difference between this embodiment and embodiment 1 is that the locking rod 38 is replaced by a plastic sheet, for example, plastic. When the piston 36 moves leftward, the plastic sheet can still rotate into the avoiding groove 34 due to the plasticity of the plastic sheet. When the piston 36 moves rightward to reset, the piston 36 will bend the plastic sheet rightward, even clamping between the piston 36 and the sliding sleeve 30, increasing the friction between the piston 36 and the sliding sleeve 30. The bent plastic sheet can also contact the pre-tightening spring 37, clamping the piston 36.

It should be noted that for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, which will not affect the effect and practicality of the patent.
