Description

Technical Field

[0001] The utility model belongs to the technical field of sprayers, and particularly relates to a spray administration device. Background Art

[0002] The atomization inhalation method uses a high-speed oxygen flow to form the liquid medicine into a mist, which is then inhaled through the respiratory tract to achieve the purpose of treatment, treat respiratory tract infections, eliminate inflammation and edema, relieve spasms, thin the phlegm, and help expectorate. It mainly consists of a nebulizer and a breathing mask. The nebulizer is used to create a medicine mist, and the liquid medicine is concentrated at the mouth and nose through the breathing mask for inhalation.

[0003] However, this kind of nebulizer can only be used in hospitals or at home and cannot be carried around. Therefore, it is necessary to design a portable nebulizer that can be carried around. Content of the Utility Model

[0004] The utility model aims at the above problems existing in the prior art and provides a spray administration device that can be carried around and is convenient to use.

[0005] The utility model can be realized by the following technical solutions:

[0006] A spray administration device, comprising:

[0007] A housing;

[0008] A capillary seat, which is movably arranged in the housing and has a highest point position and a lowest point position. Both sides of the capillary seat have double-sided slide buttons extending outward from the side of the housing;

[0009] A spray assembly, which is arranged in the housing and connected to the capillary seat. The spray assembly has a liquid storage cavity, and the capillary in the capillary seat is inserted into the liquid storage cavity;

[0010] A pressure supply spring, which is connected to the capillary seat. When the capillary seat is moved to the lowest point position by pressing the double-sided slide buttons, the pressure supply spring is compressed. At this time, the liquid storage cavity forms a vacuum cavity, and the liquid medicine in the medicine tank flows into the liquid storage cavity through the capillary;

[0011] A release button, which is linked and cooperated with the capillary seat through an eccentric wheel. Among them,

[0012] When the capillary seat moves to its lowest point position, the release button pops out outward, and at the same time, the eccentric wheel limits the axis direction of the capillary seat;

[0013] After pressing the release button, the eccentric wheel is pushed to move and the limit on the capillary seat is released. At this time, the capillary seat resets under the action of the pressure supply spring, and the capillary pushes the liquid medicine in the liquid storage cavity upward and releases it from the head end of the spray assembly.

[0014] As a further improvement of the present utility model, a sliding opening for the bilateral slide button to slide up and down is provided on the side of the housing, and the upper and lower ends of the sliding opening are respectively the highest point position and the lowest pressing point position of the bilateral slide button.

[0015] As a further improvement of the present utility model, an opening for the release button to pop out outward is further provided on the side of the housing. The eccentric wheel is connected to the release button, and the eccentric wheel and the release button can move in the direction of the opening.

[0016] As a further improvement of the present utility model, when the capillary seat is at the highest point position, the eccentric wheel is sleeved outside the capillary seat;

[0017] When the capillary seat is at the lowest point position, the capillary seat is separated from the eccentric wheel.

[0018] As a further improvement of the present utility model, a stop spring is provided at one end of the eccentric wheel away from the release button. When the capillary seat moves to the lowest point position and is separated from the eccentric wheel, the stop spring pushes the eccentric wheel outward. At this time, the release button pops out outward and the eccentric wheel limits the axial direction of the capillary seat.

[0019] As a further improvement of the present utility model, a one-way valve is provided at one end of the capillary inserted into the liquid storage cavity. When the capillary seat moves to the lowest point position, a vacuum cavity is formed between the spray assembly and the capillary, and the one-way valve is opened by the vacuum and the liquid medicine flows into the liquid storage cavity;

[0020] After pressing the release button, the capillary seat resets upward under the action of the pressure supply spring, the one-way valve closes, and the capillary pushes the liquid medicine in the liquid storage cavity upward.

[0021] As a further improvement of the present utility model, the jet end of the spray assembly has a spray head, and the liquid medicine is sprayed outward in a mist through the spray head.

[0022] As a further improvement of the present utility model, it further includes:

[0023] A counter;

[0024] Spiral counting ring, a linkage mechanism is formed between the counter and the capillary holder through the spiral counting ring. As the capillary holder moves axially, it drives the spiral counting ring to rotate, causing the counter to move up and down.

[0025] As a further improvement of the present utility model, a ring of upper gear teeth and a ring of lower tooth grooves are provided on the outer circumference of the capillary holder, and a number of convex points are provided on the inner circumference of the spiral counting ring. As the capillary holder moves up and down, the convex points move along the upper gear teeth and the lower tooth grooves. At this time, the spiral counting ring rotates unidirectionally in place and drives the counter to move unidirectionally.

[0026] As a further improvement of the present utility model, when the spray assembly completes one spray, the capillary holder completes one round trip conversion between the highest point position and the lowest point position, the spiral counting ring rotates one week and the counter completes one count.

[0027] Compared with the prior art, the present utility model has the following beneficial effects:

[0028] 1. Quantitative drug delivery: The action of one spray is realized by the capillary holder making a round trip conversion between the highest point position and the lowest point position, thereby ensuring that the drug dosage for each time is consistent and achieving the purpose of quantitative drug delivery;

[0029] 2. Easy to operate: When in use, the user can place the thumb on the bottom of the housing, press the bilateral slide buttons with the index finger and middle finger at the same time, and finally press the release button to complete one spray action. The whole operation process can be completed with only one hand;

[0030] 3. Safe and reliable: The mechanical locking mechanism is adopted to ensure that the liquid medicine will not be accidentally released in the non-activated state, improving the safety of use;

[0031] 4. Easy to carry: The whole spray drug delivery device is small in size and does not require an additional power source. As long as there is still medicine in the medicine tank, it can be carried around and used at any time;

[0032] 5. There is a linkage effect among the capillary holder, the eccentric wheel and the stop spring. Only when the bilateral slide buttons are pressed to move the capillary holder to the lowest point position, the stop spring will push the eccentric wheel outwards, playing a limiting role on the capillary holder to prevent it from rebounding. At the same time, the release button pops outwards, and the popping out of the release button provides a clear visual and tactile signal for the user, informing them that the liquid medicine has been filled and can be sprayed;

[0033] 6. The combined design of the capillary seat, eccentric wheel, and stop spring ensures that the liquid medicine can only be ejected when the liquid medicine is completely filled and the release button is correctly operated, avoiding waste or unnecessary release of the liquid medicine. In addition, the pop-up of the release button is an obvious user feedback, informing the user that the liquid medicine is ready and the next operation can be carried out, that is, pressing the release button to eject. This immediate feedback reduces operation errors and improves user confidence and satisfaction.

[0034] 7. A linkage structure is formed among the capillary seat, spiral counting ring, and counter. When performing the spraying action, as the capillary seat moves, it will drive the counter to move up and down through the spiral counting ring, thereby recording the usage times or the dosage of the device, facilitating the user to monitor the remaining dosage and avoiding overuse or underuse.

[0051] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical methods of the present invention are further described, but the present invention is not limited to these embodiments.

[0052] As Figures 1-6 shown, the present invention provides a spray administration device, including:

[0053] Housing 100;

[0054] Capillary seat 110, which is movably arranged in the housing 100 and has a highest point position and a lowest point position. Both sides of the capillary seat 110 have double-sided sliding buttons 120 extending outward from the side of the housing 100;

[0055] Spray assembly 130, which is arranged in the housing 100 and connected to the capillary seat 110. The spray assembly 130 has a liquid storage cavity 131, and the capillary 111 in the capillary seat 110 is inserted into the liquid storage cavity 131;

[0056] Pressure supply spring 140, which is connected to the capillary seat 110. When the capillary seat 110 is moved to the lowest point position by pressing the double-sided sliding buttons 120, the pressure supply spring 140 is compressed. At this time, the liquid storage cavity 131 forms a vacuum cavity, and the liquid medicine in the medicine tank 200 flows into the liquid storage cavity 131 through the capillary 111;

[0057] Release button 150, which is linked and cooperated with the capillary seat 110 through an eccentric wheel 151. Among them,

[0058] When the capillary seat 110 moves to its lowest point position, the release button 150 pops out outward, and at the same time, the eccentric wheel 151 limits the axis direction of the capillary seat 110;

[0059] When the release button 150 is pressed, the eccentric wheel 151 is pushed to move and the limit on the capillary seat 110 is released. At this time, the capillary seat 110 resets under the action of the pressure supply spring 140, and the capillary 111 pushes the liquid medicine in the liquid storage cavity 131 to move upward and be released from the head end of the spray assembly 130.

[0060] That is to say, when in use, only need to first press the double-sided sliding buttons 120 to the lowest point position, and then press the release button 150 to complete a spray action. The operation is simple and convenient. In addition, the spray administration device at least also has the following advantages:

[0061] 1. Quantitative drug delivery: The movement of a single spray is achieved by the capillary base 110 reciprocating between the highest point position and the lowest point position, thereby ensuring a consistent drug delivery dose each time and achieving the purpose of quantitative drug delivery;

[0062] 2. Easy to operate: When using, the user can place the thumb on the bottom of the housing 100, press the bilateral slide buttons 120 with the index finger and middle finger simultaneously, and finally press the release button 150 to complete a single spray action. The entire operation process can be completed with one hand;

[0063] 3. Safe and reliable: The mechanical locking mechanism ensures that the liquid medicine will not be accidentally released in the non-activated state, improving the safety of use;

[0064] 4. Easy to carry: The entire spray drug delivery device is small in size and does not require an additional power source. As long as there is still medicine in the medicine tank 200, it can be carried around and used at any time.

[0065] Preferably, a sliding opening for the bilateral slide buttons 120 to slide up and down is provided on the side of the housing 100. The upper and lower ends of the sliding opening are respectively the highest point position and the lowest pressing point position of the bilateral slide buttons 120, thereby limiting the moving range of the capillary base 110. This ensures that the movement of the capillary base 110 will not exceed the expected stroke, and the moving range of the capillary base 110 is related to the spray dose each time. Therefore, by reasonably adjusting the maximum moving range of the capillary base 110, the spray dose each time can be adjusted to the required dose.

[0066] Preferably, an opening for the release button 150 to pop out outward is also provided on the side of the housing 100. The eccentric wheel 151 is connected to the release button 150, and the eccentric wheel 151 and the release button 150 can move in the direction of the opening. In addition, when the capillary base 110 is at the highest point position, the eccentric wheel 151 is sleeved outside the capillary base 110, and when the capillary base 110 is at the lowest point position, the capillary base 110 is separated from the eccentric wheel 151.

[0067] Furthermore, a stop spring 152 is provided at one end of the eccentric wheel 151 away from the release button 150. When the capillary base 110 moves to the lowest point position and is separated from the eccentric wheel 151, the stop spring 152 pushes the eccentric wheel 151 outward. At this time, the release button 150 pops out outward and the eccentric wheel 151 limits the axis direction of the capillary base 110.

[0068] It is worth mentioning here that in this embodiment, there is a linkage among the capillary seat 110, the eccentric wheel 151, and the stop spring 152. Only when the double-sided slider 120 is pressed to move the capillary seat 110 to the lowest point position, the stop spring 152 will push the eccentric wheel 151 outward, playing a limiting role on the capillary seat 110 to prevent its rebound, and at the same time, the release button 150 pops out outward. The pop-out of the release button 150 provides a clear visual and tactile signal to the user, informing them that the liquid medicine has been filled and can be sprayed.

[0069] This combined design ensures that the liquid medicine can only be sprayed out when the liquid medicine is completely filled and the release button 150 is correctly operated, avoiding the waste or unnecessary release of the liquid medicine. In addition, the pop-out of the release button 150 is an obvious user feedback, informing the user that the liquid medicine is ready and the next step can be carried out, that is, pressing the release button 150 to spray. This immediate feedback reduces operation errors and improves user confidence and satisfaction.

[0070] And through the mechanical linkage of the eccentric wheel 151, the stop spring 152, and the release button 150, the entire drug administration process becomes smooth and efficient. Without an additional power source, the inhalation, storage, and spraying of the liquid medicine can be completed only relying on mechanical principles.

[0071] Preferably, a one-way valve 1111 is provided at one end of the capillary 111 inserted into the liquid storage cavity 131. When the capillary seat 110 moves to the lowest point position, a vacuum cavity is formed between the spray assembly 130 and the capillary 111, and the one-way valve 1111 is opened by the vacuum and the liquid medicine flows into the liquid storage cavity 131;

[0072] After the release button 150 is pressed, the capillary seat 110 is reset upward under the action of the pressure supply spring 140, the one-way valve 1111 closes, and the capillary 111 pushes the liquid medicine located in the liquid storage cavity 131 upward.

[0073] The setting of the one-way valve 1111 has the following characteristics:

[0074] 1. Ensure the one-way flow of the liquid medicine: The one-way valve 1111 is arranged at one end of the capillary 111 inserted into the liquid storage cavity 131. Its function is to only allow the liquid medicine to flow from the medicine tank 200 into the liquid storage cavity 131, while preventing reverse flow. This can prevent the backflow of the liquid medicine in the non-spraying state, ensuring the accurate measurement and spraying efficiency of the liquid medicine;

[0075] 2. Opened by using the vacuum effect: When the capillary seat 110 moves to the lowest point, a negative pressure will be generated in the vacuum chamber formed between the spray assembly 130 and the capillary 111. This negative pressure is sufficient to overcome the closing force of the one-way valve 1111 and open it, allowing the liquid medicine to flow from the medicine tank 200 through the capillary 111 into the liquid storage chamber 131;

[0076] 3. Automatically closed to retain the liquid medicine: When the user presses the release button 150, the capillary seat 110 starts to reset under the action of the pressure supply spring 140. At this time, the pressure in the vacuum chamber gradually returns to normal, and the one-way valve 1111 automatically closes to prevent the liquid medicine from flowing back, ensuring that the liquid medicine remains in the liquid storage chamber 131 and is ready to be sprayed;

[0077] 4. Improve the spraying effect: When the capillary seat 110 resets, the closing of the one-way valve 1111 ensures that the liquid medicine in the liquid storage chamber 131 can be completely pushed upward to the nozzle of the spray assembly 130, thereby achieving efficient and uniform spraying of the liquid medicine.

[0078] Preferably, the spraying end of the spray assembly 130 has a spray head 132, and the liquid medicine is sprayed out in a mist shape through the spray head 132. The spray head 132 can be selected with different structures according to actual needs. For example, by setting a number of gradually narrowing flow channels, large liquid droplets are converted into small liquid droplets, and then the high-speed small liquid droplets are turned into effective atomized particles in the micron range by impact.

[0079] Preferably, it further includes:

[0080] A counter 160;

[0081] A spiral counting ring 170. A linkage mechanism is formed between the counter 160 and the capillary seat 110 through the spiral counting ring 170. As the capillary seat 110 moves axially, it drives the spiral counting ring 170 to rotate so that the counter 160 moves up and down.

[0082] That is to say, a linkage structure is formed among the capillary seat 110, the spiral counting ring 170, and the counter 160. When performing the spraying action, as the capillary seat 110 moves, it will drive the counter 160 to move up and down through the spiral counting ring 170, thereby recording the usage times or the dosage of the liquid medicine, facilitating the user to monitor the remaining dosage and avoiding overuse or underuse.

[0083] Specifically, a ring of upper gear teeth 112 and a ring of lower gear teeth 113 are provided on the outer circumference of the capillary seat 110. A number of convex points 171 are provided on the inner circumference of the spiral counting ring 170. A region for the convex points 171 to move is formed between the upper gear teeth 112 and the lower gear teeth 113. Among them,

[0084] The upper gear ring 112 and the lower gear ring 113 are misaligned and have different inclination angles, so that during the up and down movement of the capillary seat 110, the convex points 171 of the spiral counting ring 170 can always move unidirectionally along the tooth surfaces of the upper gear ring 112 and the lower gear ring 113, enabling the spiral counting ring 170 to rotate unidirectionally in place. The counter 160 has a counting tooth surface 161 that meshes with the external thread 172 of the spiral counting ring 170. Thus, with the unidirectional rotation of the spiral counting ring 170, the counter 160 can be driven to move unidirectionally, thereby achieving the purpose of quantitative counting of the counter 160.

[0085] Furthermore, the specific counting principle is as follows:

[0086] When the spray assembly 130 completes one spray, the capillary seat 110 completes one round trip conversion between the highest point position and the lowest point position. The spiral counting ring 170 rotates one week and the counter 160 completes one count, that is, for each spray action, the counter 160 completes one count, thereby ensuring that the user can monitor the remaining dose.

[0087] In addition, a display window 180 is also provided on the housing 100 to display the remaining dose or the number of uses, helping the user to know when to replace the medicine or make a supplement.

[0088] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed by the above technical means, but also include technical solutions composed of any combination of the above technical features. The above is the specific implementation manner of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.

[0089] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, the directional indications will also change accordingly.

[0090] In addition, in the present utility model, descriptions such as "first", "second", "one", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0091] In the present utility model, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or an integral one; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0092] In addition, the technical solutions between various embodiments of the present utility model can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
