[0028] In order to make the above-mentioned objectives, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0029] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0030] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is separate or alternative to other embodiments.

[0031] Embodiment 1

[0032] Reference Figures 2-9 For the first embodiment of the present application, the embodiment provides a postoperative care spray device for otolaryngology, which comprises a protective assembly 200, including a base 201 and a protective piece 202, the protective piece 202 is arranged in the base 201, the protective piece 202 comprises a protective plate 202a and a shielding plate 202b, the protective plate 202a is located in the base 201, and the shielding plate 202b is fixed on the protective plate 202a.

[0033] The base 201 is used to support the atomizing pump, the number of protective pieces 202 is four, which are located at the four edges inside the base 201, a through slot is formed on the base 201, and the protective plate 202a is movably connected in the through slot.

[0034] The protection plate 202a is T-shaped, and when the four protection plates 202a are hidden inside the base 201, they will not hinder and interfere with each other. Two shielding plates 202b are fixed on one protection plate 202a, which fills the blank position on both sides of the protection plate 202a. The adjacent two shielding plates 202b are in an upper and lower stacked state, thereby avoiding the contact between the adjacent shielding plates 202b and the obstruction to each other.

[0035] When the atomizing pump is normally used on the desktop, the protection plate 202a will be hidden inside the base 201, thereby not blocking the atomizing pump and not occupying too much extra space, making the placement of the atomizing pump more convenient and flexible. When the atomizing pump falls from the desktop, the protection plate 202a will move outward and rotate to a vertical state, and will be in contact with the atomizing pump. In this way, the protection plate 202a and the shielding plate 202b can protect the atomizing pump, avoiding the case that the atomizing pump will be in contact with the raised parts on the ground when falling, which will cause the shell to be broken.

[0036] The protection piece 202 further comprises a buffer piece 203 arranged on the protection piece 202, including a positioning plate 203a, a buffer pad 203b, a connecting rod 203c, a supporting column 203d, a positioning block 203e, a first spring 203f, a movable plate 203g, and a second spring 203h. The protection plate 202a is provided with a groove 202a-1, and the positioning plate 203a is located in the groove 202a-1. The buffer pad 203b is fixed on the top of the positioning plate 203a. The top end of the connecting rod 203c is hinged to the positioning plate 203a through a hinge plate. The supporting column 203d is fixed in the groove 202a-1. The positioning block 203e is located outside the supporting column 203d. The bottom side of the connecting rod 203c is rotationally connected to the positioning block 203e through a rotating shaft. The first spring 203f is sleeved outside the supporting column 203d, and the two ends are respectively fixed with the positioning block 203e and the inner wall of the groove 202a-1. The protection plate 202a is provided with a slot 202a-2, and the movable plate 203g is inserted into the slot 202a-2. The two ends of the second spring 203h are respectively fixed with the inner wall of the slot 202a-2 and the movable plate 203g.

[0037] There are two groups of buffer pieces 203 on one protection plate 202a, which are respectively located on both sides of the protection plate 202a. There are two connecting rods 203c in one group of buffer pieces 203, which are respectively located on both sides of the bottom of the positioning plate 203a. The two connecting rods 203c are both inclined. There are two supporting columns 203d, which are respectively fixed on both sides of the groove 202a-1. There are four first springs 203f, which are respectively sleeved on both ends of the two supporting columns 203d. When the protection plate 202a is located inside the base 201, the top of the buffer pad 203b will be in contact with the inner wall of the through groove and will be limited by the through groove and cannot move.

[0038] When the protection plate 202a is rotated to the vertical state, the first spring 203f will exert a pushing force on the positioning block 203e, causing the two positioning blocks 203e to move to a close position, and the positioning block 203e will push the connecting rod 203c to rotate to the vertical state, and then push the positioning plate 203a and the buffer pad 203b to move, so that the buffer pad 203b contacts the side of the atomizing pump. When the atomizing pump contacts the ground, the impact force generated by the atomizing pump on the buffer pad 203b and the first spring 203f can be buffered, so as to avoid physical damage such as loosening or damage of internal components caused by vibration of the atomizing pump.

[0039] When the buffer pad 203b contacts the side of the atomizing pump, the second spring 203h will push the movable plate 203g to move outward, so that the end of the movable plate 203g is higher than the top of the atomizing pump. If the atomizing pump falls downward, the top is downward, and then the movable plate 203g will first contact the ground, and the atomizing pump can be buffered by the second spring 203h, so as to protect the atomizing pump in all directions.

[0040] The protection assembly 200 further comprises a rotating member 204 arranged in the base 201, which comprises a rotating disc 204a, a connecting block 204b, a movable block 204c, a rotating column 204d, a rotating rod 204e and a guide shaft 204f. The rotating disc 204a is located in the base 201, the connecting block 204b is fixed to one side of the protection plate 202a, the movable block 204c is located on the top of the rotating disc 204a, the rotating column 204d is fixed in the connecting block 204b and movably connected with the movable block 204c, the rotating rod 204e is fixed to the outer side of the rotating column 204d, and the guide shaft 204f is fixed to the bottom of the movable block 204c. The rotating disc 204a is provided with a guide groove 204a-1, and the guide shaft 204f slides in the guide groove 204a-1.

[0041] The number of rotating members 204 corresponds to the protection member 202, and the guide groove 204a-1 is arc-shaped. When the rotating disc 204a rotates, the guide shaft 204f slides in the guide groove 204a-1, so as to drive the movable block 204c and the connecting block 204b to move, and then the connecting block 204b drives the protection plate 202a to move outward from the base 201. When the protection plate 202a is completely moved out of the base 201, the rotating rod 204e will contact the inner wall of the base 201, and with the continuous movement of the movable block 204c, the rotating rod 204e will be extruded by the inner wall of the base 201 to rotate, and drive the rotating column 204d and the connecting block 204b to rotate, so as to drive the connecting block 204b to rotate the protection plate 202a upward to the vertical state.

[0042] Example 2

[0043] Referring to Figures 2-9 For the second embodiment of the present application, which is based on the previous embodiment.

[0044] Specifically, the protection assembly 200 further comprises a driving member 205 arranged at the bottom of the rotating member 204, which comprises a supporting sleeve 205a, a fixed column 205b and a torsional spring 205c. The supporting sleeve 205a is fixed in the base 201, the top end of the fixed column 205b is fixed with the rotating disc 204a, the bottom end is rotatably connected with the supporting sleeve 205a through a bearing, and the torsional spring 205c is fixed at both ends with the fixed column 205b and the supporting sleeve 205a respectively, and the torsional spring 205c is in a tightened state.

[0045] When the fixed column 205b is released, the elastic force released by the torsional spring 205c will drive the fixed column 205b to rotate, so that the rotating disc 204a can be driven to rotate through the fixed column 205b.

[0046] Specifically, the protection assembly 200 further comprises a locking member 206 arranged at the bottom of the driving member 205, which comprises a supporting plate 206a and a limiting rod 206b. The supporting plate 206a is located in the supporting sleeve 205a, and the limiting rod 206b is fixed at the top of the supporting plate 206a. A limiting groove 205b-1 is formed at the bottom of the fixed column 205b, and the limiting rod 206b is engaged with the limiting groove 205b-1.

[0047] The limiting rod 206b is rectangular, and when the limiting rod 206b is engaged with the limiting groove 205b-1, the fixed column 205b can be limited through the cooperation of the two, so as to avoid the rotation of the fixed column 205b. The supporting plate 206a is used to support the limiting rod 206b and drive the limiting rod 206b to move.

[0048] Specifically, the supporting plate 206a has a stabilizing block 206c fixed on one side, a stabilizing column 206d fixed in the stabilizing block 206c, a third spring 206e fixed on the top of the stabilizing block 206c, the top end of the third spring 206e being fixed with the supporting sleeve 205a and sleeved outside the stabilizing column 206d, and the top end of the stabilizing column 206d penetrating above the supporting sleeve 205a and movably connected with the supporting sleeve 205a.

[0049] The number of stabilizing blocks 206c and stabilizing columns 206d is two, respectively fixed on both sides of the supporting plate 206a, and used to position the supporting plate 206a to avoid rotation of the supporting plate 206a. When the supporting plate 206a is released, the third spring 206e can exert a downward pushing force on the stabilizing block 206c, so that the supporting plate 206a and the limiting rod 206b can be driven to move downward through the stabilizing block 206c, and the limiting rod 206b can be separated from the limiting groove 205b-1.

[0050] Specifically, the support sleeve 205a is provided with a blocking ball 206f, and the top of the blocking ball 206f is in contact with the support plate 206a.

[0051] The blocking ball 206f has a certain weight, and the support plate 206a is limited by the blocking ball 206f so as to be unable to move downward. When the atomizing pump falls downward from the desktop, the atomizing pump is in an inclined state, and the blocking ball 206f moves in the inclined direction and is separated from the bottom of the support plate 206a, so as to release the limitation on the support plate 206a.

[0052] Specifically, the movable plate 203g is provided with a movable slot 203g-1, the movable slot 203g-1 is provided with a locking rod 203g-2, one side of the locking rod 203g-2 is fixedly provided with a fourth spring 203f-3, the protection plate 202a is provided with a limiting hole 202a-3, the locking rod 203g-2 is clamped with the limiting hole 202a-3, and one side of the locking rod 203g-2 is inclined.

[0053] The locking rod 203g-2 is clamped with the limiting hole 202a-3, so as to lock the movable plate 203g and avoid that the movable plate 203g is moved outward by the elastic force of the second spring 203h when the protection plate 202a is in the base 201. The fourth spring 203f-3 is arranged to apply a pushing force to the locking rod 203g-2, so as to make the locking rod 203g-2 and the limiting hole 202a-3 be more tightly clamped.

[0054] Embodiment 3

[0055] Reference Figures 1-9 This is the third embodiment of the present application, which is based on the first two embodiments.

[0056] Specifically, the limiting hole 202a-3 is provided with a push rod 203f-4, one end of the push rod 203f-4 is in contact with the locking rod 203g-2, the other end of the push rod 203f-4 is inclined, and one side of the positioning block 203e is fixedly provided with an extrusion rod 203g-5.

[0057] The extrusion rod 203g-5 is L-shaped, when the positioning block 203e moves, the extrusion rod 203g-5 is also moved, and the extrusion rod 203g-5 extrudes the inclined surface of the push rod 203f-4, so as to push the push rod 203f-4 to move, and the push rod 203f-4 pushes the locking rod 203g-2 to move, so as to make the locking rod 203g-2 and the limiting hole 202a-3 be separated, and then the limitation on the movable plate 203g is released.

[0058] Specific, the protection assembly 200 further comprises a limiting piece 207, which is arranged on one side of the base 201 and comprises a pull rod 207a, a stabilizing plate 207b and a limiting column 207c. The pull rod 207a is fixed on one side of the rotating disc 204a, the stabilizing plate 207b is fixed on one side of the base 201, and the limiting column 207c is inserted into the stabilizing plate 207b. A hole 207a-1 corresponding to the limiting column 207c is formed in the pull rod 207a.

[0059] The top end of the limiting column 207c is inclined on one side, and a sliding groove is formed in the base 201. The pull rod 207a is movably connected in the sliding groove. When the rotating disc 204a is rotated, the pull rod 207a can be reset. When the rotating disc 204a stops rotating, the pull rod 207a will contact the top of the limiting column 207c, and the limiting column 207c will be clamped in the hole 207a-1. The pull rod 207a and the rotating disc 204a are locked by the cooperation of the two, so that the rotating disc 204a cannot rotate, thereby avoiding the movement of the protective plate 202a when it is vibrated.

[0060] Specifically, the bottom end of the limiting column 207c is fixed with a mounting block 207d, and the top of the mounting block 207d is fixed with a sixth spring 207e. The top end of the sixth spring 207e is fixed with the stabilizing plate 207b.

[0061] The sixth spring 207e applies an upward pushing force to the mounting block 207d, and the mounting block 207d drives the limiting column 207c to move, so that the limiting column 207c is clamped in the hole 207a-1 more tightly.

[0062] Specifically, the device further comprises a medicine spraying assembly 100 arranged on the top of the protection assembly 200, which comprises an atomizing pump 101, an atomizing cup 102, a mouthpiece 103 and a connecting pipe 104. The atomizing pump 101 is fixed on the top of the base 201, the atomizing cup 102 is arranged on one side of the atomizing pump 101, the mouthpiece 103 is arranged on the atomizing cup 102, and the connecting pipe 104 is arranged at the bottom of the atomizing cup 102.

[0063] The atomizing pump 101 is used to generate compressed air, which is delivered to the atomizing cup 102 through the connecting pipe 104. In this way, the medicine in the atomizing cup 102 can be atomized, and the atomized medicine can be covered on the wound position of the throat of the patient through the mouthpiece 103. This is a prior art, and the working principle is not described in detail in this scheme. Those skilled in the art can clearly understand the working principle.

[0064] In summary, the ear and throat postoperative nursing medicine sprayer has the following advantages:

[0065] I. When the atomizing pump 101 falls from the table, the protection assembly 200 can protect the atomizing pump 101 and buffer the impact force of the falling, so as to avoid the atomizing pump 101 from being damaged;

[0066] II. When the atomization pump 101 is normally used on the desktop, the protection assembly 200 is in a hidden state, so as not to hinder the operation of the medical staff on the atomization pump 101;

[0067] III. When the atomization pump 101 falls, the protection assembly 200 will instantaneously pop out, and the response is timely.

[0068] When in use, when the atomization pump falls from the desktop, the atomization pump will be in an inclined state at this time, and the blocking ball 206f will move in the inclined direction and separate from the bottom of the support plate 206a, so as to release the restriction on the support plate 206a. The third spring 206e exerts a downward pushing force on the stabilizing block 206c, so that the stabilizing block 206c drives the support plate 206a and the limiting rod 206b to move downward, so that the limiting rod 206b is separated from the limiting groove 205b-1.

[0069] When the fixed column 205b is released, the elastic force released by the torsional spring 205c will drive the fixed column 205b to rotate, so that the fixed column 205b drives the rotating disc 204a to rotate. When the rotating disc 204a rotates, the guide shaft 204f will slide in the guide groove 204a-1, so that the guide shaft 204f drives the movable block 204c and the connecting block 204b to move, and then the connecting block 204b drives the protection plate 202a to move outward from the base 201. When the protection plate 202a is completely moved out of the base 201, the rotating rod 204e will contact the inner wall of the base 201 at this time, and with the continuous movement of the movable block 204c, the rotating rod 204e will be extruded by the inner wall of the base 201. Rotate and drive the rotating column 204d and the connecting block 204b to rotate, so that the connecting block 204b drives the protection plate 202a to rotate upward to a vertical state.

[0070] When the protection plate 202a rotates to a vertical state, the first spring 203f will exert a pushing force on the positioning block 203e, so that the two positioning blocks 203e move to a position close to each other. At this time, the positioning block 203e will push the connecting rod 203c to rotate to a vertical state, and then push the positioning plate 203a and the buffer pad 203b to move, so that the buffer pad 203b contacts the side surface of the atomization pump. When the atomization pump contacts the ground, the impact force generated by the atomization pump can be buffered by the buffer pad 203b and the first spring 203f, so as to avoid physical damage such as loosening or damage of internal components caused by vibration of the atomization pump.

[0071] When the buffer pad 203b is in contact with the side of the atomizing pump, the second spring 203h will push the movable plate 203g to move outward, so that the end of the movable plate 203g is higher than the top of the atomizing pump. If the atomizing pump falls downward, the top is downward, and then the movable plate 203g will first contact the ground, and the atomizing pump can be buffered by the second spring 203h, so that the atomizing pump can be protected in all directions.

[0072] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
