Description

Technical Field

[0001] The utility model relates to the technical field of maternal and infant products, in particular to an infant medicine feeding aid. Background Art

[0002] In the method of feeding medicine to babies, liquid medicine can be delivered by a small spoon, powder medicine can be delivered by a nipple or pacifier, etc., but for liquid medicine and granules with a large oral dosage, families generally use special baby medicine feeders. According to the form of drug extrusion, the most common forms of such baby medicine feeders include extrusion type and push type. The extrusion type medicine feeder usually includes a balloon and a medicine tube. When in use, the balloon is squeezed to exhaust and the medicine liquid is inhaled through the medicine tube, and then the medicine tube is inserted into the baby's mouth, and the balloon is squeezed again to squeeze the medicine liquid into the baby's mouth. The push type medicine feeder includes a plunger structure and a soft head connected to the front end of the plunger structure. When inhaling medicine, the soft head is separated from the plunger structure, and the plunger structure is connected to the soft head after the medicine is inhaled, and then the soft head is inserted into the baby's mouth, and the plunger structure is pushed to squeeze the medicine liquid into the baby's mouth through the soft head.

[0003] When feeding medicine to babies, parents can choose the appropriate type of baby feeding aid. For example, when the amount of medicine to be fed is small, a small spoon or a squeeze-type medicine feeder can be selected. When the amount of medicine to be fed is large, although the push-type medicine feeder has a larger structure and is relatively complicated to use, it is easier to control the flow rate of the medicine squeezed out, has a better effect in preventing choking, and at the same time, the amount of medicine inhaled at a single time is larger.

[0004] With the continuous enrichment of maternal and infant products, the functions of infant medicine feeding aids are not limited to the functions of drug inhalation and delivery. For example, regarding the structural design of a push-type medicine feeder, the prior art discloses a technical solution with a patent application number of CN201610145022.6 and an invention name of a push-rod infant medicine feeding device. This solution can effectively reduce the stimulation of drugs on the taste buds of infants, and achieve functions such as smooth medicine feeding and anti-choking medicine feeding.

[0005] In order to make the medicine feeding process more friendly to infants, it is necessary to further optimize the auxiliary equipment used for medicine feeding for infants. Utility Model Content

[0006] The utility model provides a baby medicine feeding assistant, which is used to achieve: making the extrusion flow rate of the medicine liquid in the medicine feeding process easier to control and being more friendly to the baby.

[0007] In view of the above problems, the utility model provides an infant medicine feeding aid to solve the problems through the following technical points: an infant medicine feeding aid, including a plunger structure, the plunger structure including a cylinder and a push rod, the front end of the push rod is provided with a push plug, the push plug serves as a piston in the cylinder and is installed in the cylinder, and also includes an end cap for being installed at the front end of the cylinder and a nipple cover installed on the end cap, the front end of the cylinder is installed with a filter screen, the end cap includes a flat plate for blocking the front end of the cylinder, and also includes a conduit, one end of the conduit passes through the flat plate and communicates with the cylinder, the other end of the conduit extends to the front end of the nipple cover and communicates with the medicine outlet hole located at the front end of the nipple cover, and the rear end of the nipple cover is fixed to the front end of the flat plate.

[0008] The auxiliary device is an auxiliary device that realizes feeding medicine to babies by pushing and squeezing. The specific method of use is as follows: for liquid medicine, the push plug is pushed and pulled by the rear end of the push rod. When the push plug moves toward the rear end of the cylinder, the volume cavity between the push plug and the front end of the cylinder becomes larger, and the medicine can be sucked through the front end of the cylinder. When the push plug moves toward the front end of the cylinder, the volume cavity between the push plug and the front end of the cylinder becomes smaller, and the medicine can be squeezed out through the front end of the cylinder. For granular medicine that needs to be dissolved during medicine feeding, the push rod and the push plug are first pulled out of the cylinder, and then the granules are pushed out from the rear end of the cylinder. The granular medicine is poured into the cylinder, and then the push rod and the push plug are pushed into the cylinder and the push plug is moved to a position close to the filter screen. At this time, the granular medicine is sandwiched between the push plug and the filter screen, and then the push plug is pulled to move the push plug backward in the cylinder to absorb the dissolving water from the front end of the cylinder. After the dissolving water is absorbed to the required amount, the push plug continues to move backward and absorbs a certain amount of air, and then the cylinder is shaken to accelerate the dissolution of the granular medicine. After the dissolution is completed, the push rod is pushed to move the push plug forward to squeeze out the medicine liquid; for the granular medicine that needs to be dissolved when feeding, the container can also be used to first After the medicine is dissolved into liquid medicine, the liquid medicine is poured into the cylinder before the push plug is inserted into the cylinder, and then the push plug is inserted into the cylinder. However, this operation method requires attention to the excessive waste of liquid medicine caused by the insertion process of the push plug; the liquid medicine can be sucked into the cylinder from the front end through the nipple cover. The preferred application is to set the nipple cover to be detachable relative to the cylinder so that the nipple cover can be removed when the liquid medicine is added through the front end of the cylinder to speed up the liquid absorption speed of the cylinder. In addition, a more preferred application is to set a boss in the inner hole at the front end of the cylinder, and the filter screen is sandwiched between the boss and the flat plate. When it is needed to suck the liquid into the cylinder, the filter screen can be placed in the cylinder. When pouring the dissolved medicine, the front end of the cylinder is opened, the push plug moves backward in the cylinder, the dissolved medicine is poured in from the front end of the cylinder, and then the filter screen and the end cap are installed, and then the push plug is pushed to make the push plug move forward to squeeze out the medicine to achieve medicine feeding. When the cylinder needs to be used to dissolve granular medicine, the front end of the cylinder is opened, the push plug moves backward in the cylinder, granular medicine and dissolving water are added from the front end of the cylinder, and then the filter screen and the end cap are installed, and then the cylinder is shaken to accelerate the dissolution of the medicine. After the dissolution is completed, the push plug is pushed to make the push plug move forward to squeeze out the medicine to achieve medicine feeding.

[0009] Different from the prior art, for the liquid medicine prepared from granular medicine during use, since there is a possibility of residual particles in the liquid medicine added to or formed in the cylinder, the present solution is configured to include a filter, which can effectively prevent the residual particles from entering the catheter and the medicine outlet hole. In order to reduce the residual medicine on the auxiliary device after the pusher moves to the front end of the cylinder, the catheter should adopt a smaller tube hole diameter and the medicine outlet hole should adopt a smaller aperture. In this way, due to the presence of the filter, when the push rod is pushed to use the front end of the pacifier cover to feed the baby medicine, even if these residual particles block some of the meshes on the filter, it can still ensure that the medicine is After the liquid passes through the filter, it is smoothly discharged through the catheter and the medicine outlet hole. The anti-blocking function of the filter makes the medicine flow rate more uniform during the entire medicine discharging process. Since the resistance of the pushing push rod is relatively constant, the purpose of making the medicine liquid extrusion flow rate during the feeding process easier to control can be achieved. In addition, in the relatively stable pushing push rod process, the flow rate decreases after the catheter and the medicine outlet hole are blocked. Further pushing and pushing the plug can be squeezed out when the pressure at the rear end of the blockage increases, but it will cause a sudden increase in instantaneous flow rate, resulting in a jet situation that is significantly higher than the normal feeding amount. This solution can avoid the baby choking on the medicine due to flow fluctuations caused by blockage, making the entire medicine feeding process more friendly to babies.

[0010] In the prior art, the medicine feeding aid with a pacifier cover at the front end directly uses the cavity inside the pacifier cover as a channel for the medicine liquid during medicine feeding. The difference between the present solution and the prior art also includes a catheter. Compared with the space inside the pacifier cover, the tube hole of the catheter has a smaller volume. In this way, the amount of medicine liquid retained in the aid after the push plug moves to the front end of the cylinder can be effectively reduced, which is beneficial to accurate medicine feeding and reducing the waste of medicine liquid.

In this embodiment, the rubber isolation sleeve is the outermost structure of the push plug and cooperates with the inner wall of the cylinder body to form the sealing surface. The integrated structure prevents the push plug and the push rod from relative displacement, causing the rubber isolation sleeve to be pulled, causing the drug solution to enter the inner side of the rubber isolation sleeve, and causing trouble for the cleaning of the auxiliary device.

[0017] In a specific embodiment, in order to facilitate cleaning of the filter screen, the filter screen is a single-layer metal filter screen.

[0018] In a specific embodiment, in order to facilitate cleaning of the filter screen, the filter screen is detachably connected to the cylinder.

[0019] In a specific embodiment, an external thread is provided on the outer side surface of the front end of the cylinder, the end cap includes a cylindrical section, the flat plate is provided at the front end of the cylindrical section, an internal thread is provided on the inner side surface of the rear end of the cylindrical section, the end cap is detachably connected to the cylinder through the external thread and the internal thread, a boss is provided in the inner hole at the front end of the cylinder, and the filter screen is clamped between the boss and the flat plate.

[0029] The present invention is further described in detail below in conjunction with the embodiments, but the present invention is not limited to the following embodiments:

[0030] Embodiment 1:

[0031] like Figure 1 and Figure 2 As shown, a baby medicine feeding aid includes a plunger structure, which includes a cylinder 6 and a push rod 2. A push plug 4 is arranged at the front end of the push rod 2. The push plug 4 serves as a piston in the cylinder 6 and is installed in the cylinder 6. It also includes an end cap 8 for installation at the front end of the cylinder 6 and a nipple cover 10 installed on the end cap 8. A filter screen 7 is installed at the front end of the cylinder 6. The end cap 8 includes a flat plate 12 for blocking the front end of the cylinder 6. It also includes a conduit 9. One end of the conduit 9 passes through the flat plate 12 and communicates with the cylinder 6, and the other end of the conduit 9 extends to the front end of the nipple cover 10 and communicates with the medicine outlet hole 11 located at the front end of the nipple cover 10. The rear end of the nipple cover 10 is fixed to the front end of the flat plate 12.

[0032] The auxiliary device is an auxiliary device for feeding medicine to babies by pushing and squeezing. The specific method of use is as follows: for liquid medicine, the push plug 4 is pushed and pulled by the rear end of the push rod 2. When the push plug 4 moves toward the rear end of the cylinder 6, the volume cavity between the push plug 4 and the front end of the cylinder 6 becomes larger, and the medicine can be sucked through the front end of the cylinder 6. When the push plug 4 moves toward the front end of the cylinder 6, the volume cavity between the push plug 4 and the front end of the cylinder 6 becomes smaller, and the medicine can be squeezed out through the front end of the cylinder 6. For granular medicines that need to be dissolved during medicine feeding, the push rod 2 and the push plug 4 are first pulled out of the cylinder 6, and then the granular medicine is squeezed out from the rear end of the cylinder 6. The medicine is poured into the cylinder 6, and then the push rod 2 and the push plug 4 are pushed into the cylinder 6 and the push plug 4 is moved to a position close to the filter screen 7. At this time, the granular medicine is sandwiched between the push plug 4 and the filter screen 7, and then the push plug 4 is pulled to move the push plug 4 backward in the cylinder 6 to absorb the dissolving water from the front end of the cylinder 6. After the dissolving water is absorbed to the required amount, the push plug 4 continues to move backward and absorbs a certain amount of air, and then the cylinder 6 is shaken to accelerate the dissolution of the granular medicine. After the dissolution is completed, the push rod 2 is pushed to make the push plug 4 move forward to squeeze out the medicine liquid; for the granular medicine that needs to be dissolved when feeding the medicine, it is also possible to use a container to dissolve the medicine first After the medicine is formed, the medicine is poured into the barrel 6 before the push plug 4 is placed in the barrel 6, and then the push plug 4 is placed in the barrel 6. However, this operation method requires attention to the excessive waste of medicine caused by the insertion process of the push plug 4; the medicine liquid can be sucked into the front end of the barrel 6 through the nipple cover 10. The preferred application is to set the nipple cover 10 to be detachable relative to the barrel 6, so that the nipple cover 10 can be removed when the medicine liquid is added through the front end of the barrel 6, thereby speeding up the liquid absorption speed of the barrel 6. In addition, a more preferred application is to set a boss in the inner hole at the front end of the barrel 6, and the filter screen 7 is sandwiched between the boss and the flat plate 12. When it is necessary to suck the medicine into the barrel 6 When the dissolved medicine is poured in, the front end of the cylinder 6 is open, the push plug 4 moves backward in the cylinder 6, the dissolved medicine is poured in from the front end of the cylinder 6, and then the filter screen 7 and the end cap 8 are installed, and then the push plug 4 is pushed to make the push plug 4 move forward to squeeze out the medicine to achieve drug feeding. When the cylinder 6 is needed to dissolve granular medicine, the front end of the cylinder 6 is open, the push plug 4 moves backward in the cylinder 6, granular medicine and dissolving water are added from the front end of the cylinder 6, and then the filter screen 7 and the end cap 8 are installed, and then the cylinder 6 is shaken to accelerate the dissolution of the medicine. After the dissolution is completed, the push plug 4 is pushed to make the push plug 4 move forward to squeeze out the medicine to achieve drug feeding.

[0033] Different from the prior art, for the liquid medicine prepared from granular medicine during use, since there is a possibility of residual particles in the liquid medicine filled in the cylinder 6 or formed in the cylinder 6, the present solution is configured to include a filter 7, and the filter 7 can effectively prevent the residual particles from entering the conduit 9 and the medicine outlet 11. In order to reduce the residual medicine on the auxiliary device after the push plug 4 moves to the front end of the cylinder 6, the conduit 9 should adopt a smaller tube hole diameter and the medicine outlet 11 should adopt a smaller aperture. In this way, due to the presence of the filter 7, when the push rod 2 is pushed to use the front end of the pacifier cover 10 to feed the baby medicine, even if these residual particles block some of the meshes on the filter 7, it can It is ensured that the medicine liquid passes through the filter screen 7 and then is smoothly discharged through the conduit 9 and the medicine outlet hole 11. The anti-blocking function of the filter screen 7 makes the medicine discharge flow rate more uniform during the entire medicine discharge process. Since the resistance of the pushing push rod 2 is relatively constant, the purpose of making the medicine liquid extrusion flow rate during the medicine feeding process easier to control can be achieved. In addition, in the relatively stable process of pushing the push rod 2, the flow rate decreases after the conduit 9 and the medicine outlet hole 11 are blocked. The push plug 4 is further pushed. When the pressure at the rear end of the blockage increases, the blockage can be squeezed out, but it will cause a sudden increase in the instantaneous flow rate, and a jet situation that is significantly higher than the normal medicine feeding amount will appear. This solution can avoid the baby choking on the medicine due to flow fluctuations caused by blockage, making the entire medicine feeding process more friendly to babies.
