Description

Technical Field

[0001] The utility model belongs to the field of pediatric medicine feeding, and particularly relates to a medicine feeding device for pediatric patients. Background Art

[0002] A medicine feeder is an essential medicine feeding tool for infants and young children aged 0-18 months. It is mainly used to treat babies of this age group who are prone to struggling and resisting during the medicine feeding process. With the help of a medicine feeder, the medicine liquid is directly delivered to the child's mouth. Existing medicine feeders are usually syringe structures. For example, patent CN202322757762.3 discloses a pediatric medicine feeding component that adopts a needle-like structural design. The medicine liquid in the syringe is delivered to the child's mouth by pushing the push rod. However, the force and speed of pushing the push rod are different for each person, and it is easy to push the push rod with greater force, causing the medicine liquid in the syringe to be quickly pushed out, which in turn causes the child to choke. Utility Model Content

[0003] In response to the deficiencies in the existing technology, the present invention provides a pediatric medicine feeder to solve the problem that each person pushes the push rod with different strength and speed, which can easily lead to the push rod being pushed with greater force, causing the liquid medicine in the syringe to be quickly pushed out, thereby causing the child to choke.

[0004] According to the embodiment of the present invention, the present invention adopts the following technical solutions:

[0005] A medicine feeder for pediatric patients comprises a syringe, a piston slidably connected to the syringe, and a medicine discharge nozzle detachably connected to the end of the syringe. The end of the syringe is provided with a tapered portion, and the small diameter end of the tapered portion is its free end. The medicine discharge nozzle is made of rubber and is sleeved on the outside of the tapered portion. The side wall of the medicine discharge nozzle is provided with a plurality of first medicine discharge holes along its circumference, and the side wall of the tapered portion is provided with a plurality of second medicine discharge holes connected to the medicine discharge nozzle. A flow groove is provided at a position where the middle of the medicine discharge nozzle and the second medicine discharge holes are aligned; a stopper is slidably connected to the tapered portion, and an elastic part is connected between the stopper and the small diameter end of the tapered portion. The stopper is frustum-shaped, and the small diameter end of the stopper is opposite to the small diameter end of the tapered portion. When the large diameter end of the stopper abuts against the inner wall of the tapered portion, the second medicine discharge hole is located between the stopper and the small diameter end of the tapered portion.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] 1. The rubber-made nozzle makes it easy to place in the child's mouth. Even if the liquid in the syringe is pushed too quickly, the impact of the liquid discharged from the second outlet is large, but it will be buffered in the flow groove instead of being discharged directly from the first outlet, reducing the possibility of choking. The first outlet is arranged around the nozzle and will not face the child's throat, further reducing the possibility of choking.

[0008] 2. By setting a stopper, when the liquid medicine in the syringe is pushed by the piston, the liquid medicine has a pushing force on the stopper, and the stopper is in the shape of a cone with the small diameter end facing away from the small diameter end of the tapered portion, the liquid medicine will flow to the inclined surface of the stopper, so that the liquid medicine passes through the gap between the stopper and the inner wall of the tapered portion. After the pushing force of the liquid medicine on the stopper is decomposed, the direct force on the stopper along the axis of the syringe is reduced. When the liquid medicine is pushed stably, the stopper is also subjected to the elastic force of the elastic part, so that the force on the stopper remains balanced.

[0009] When the medicine pushing speed increases, the impact force of the medicine on the block increases, overcoming the elastic force of the elastic part. The block movement and the inner wall of the tapered portion counteract each other, and the medicine can no longer be discharged into the medicine outlet nozzle through the second medicine outlet hole, thereby preventing the child from choking due to excessive medicine pushing speed.

[0010] Furthermore, a circular ring is fixed on the outer wall of the syringe, and a clamping groove for clamping on the outer side of the circular ring is provided on the medicine dispensing nozzle.

[0011] Furthermore, the inner wall of the circulation groove is arc-shaped, and the side of the circulation groove facing the first medicine outlet hole and the inner wall of the medicine outlet nozzle are smoothly transitioned.

[0012] Furthermore, the end of the syringe is detachably connected to a fixed cover, the fixed cover is threadedly connected to a push rod, and the push rod is fixed on the piston.

[0013] Furthermore, a through hole is provided on the syringe, a pressure relief valve is installed in the through hole, and the through hole is connected to a flexible bag.

[0014] Furthermore, a liquid pipe is connected between the flexible bag and the medicine dispensing nozzle, and a valve is installed in the liquid pipe.

[0015] Furthermore, an arc-shaped medicine receiving cover is fixed on the medicine dispensing nozzle, and the medicine receiving cover is used to be clamped at the chin of the child.

[0016] Furthermore, the medicine dispensing nozzle includes a mounting portion attached to the side wall of the tapered portion and a sucking portion for the child to suck, and the first medicine dispensing hole is provided on the sucking portion. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below with reference to the accompanying drawings, and specific implementation methods will be given.

[0022] like Figure 1 As shown, the pediatric medicine feeder includes a syringe 1, a piston 2 slidably connected to the syringe 1, and a medicine nozzle 5 detachably connected to the end of the syringe 1. A push rod 3 is fixed to the piston 2, which pushes the piston 2 to slide in the syringe 1, thereby assisting the syringe 1 in sucking in or pushing out the medicine. A tapered portion 4 is provided at the end of the syringe 1, and the small-diameter end of the tapered portion 4 is its free end. The medicine nozzle 5 is made of rubber and is sleeved on the outside of the tapered portion 4. Specifically, a circular ring 6 is fixed to the outer wall of the syringe 1, and a card slot for clamping on the outside of the circular ring 6 is provided on the medicine nozzle 5. During actual use, the medicine nozzle 5 can be made with reference to the shape of a pacifier in the prior art. The medicine nozzle 5 includes a mounting portion that fits on the side wall of the tapered portion 4 and a sucking portion for the child to suck. The sucking portion is similar to the pacifier in the prior art, so that it is easy to place in the child's mouth.

[0023] The side wall of the medicine dispensing nozzle 5 is provided with a plurality of first medicine dispensing holes 9 along its circumference, and the first medicine dispensing holes 9 are provided on the sucking part. The side wall of the conical part 4 is provided with a plurality of second medicine dispensing holes 8 connected to the medicine dispensing nozzle 5, and a circulation groove 7 is provided at the position where the middle part of the medicine dispensing nozzle 5 is aligned with the second medicine dispensing hole 8. Even if the liquid medicine in the syringe 1 is pushed too fast, the impact force of the liquid medicine discharged from the second medicine dispensing hole 8 is large, and it will also impact the circulation groove 7 for buffering, and then enter the medicine dispensing nozzle 5 through the circulation groove 7 and be discharged from the first medicine dispensing hole 9. In order to reduce the liquid medicine remaining in the circulation groove 7, the inner wall of the circulation groove 7 is arc-shaped, and the circulation groove 7 smoothly transitions to the side of the first medicine dispensing hole 9 and the inner wall of the medicine dispensing nozzle 5. The first medicine dispensing hole 9 is provided in the circumference of the medicine dispensing nozzle 5, and will not face the throat of the child, further reducing the possibility of choking.

[0024] A stopper 11 is slidably connected to the tapered portion 4. Specifically, a slide rod 12 is fixed to the end of the stopper 11. The slide rod 12 is slidably connected to the small-diameter end of the tapered portion 4. A limit block 13 is fixed to the end of the slide rod 12 extending from the tapered portion 4 to prevent the slide rod 12 from retracting into the tapered portion 4. An elastic member is connected between the stopper 11 and the small-diameter end of the tapered portion 4. The elastic member is a spring 10. The slide rod 12 is installed through the middle of the spring 10 to provide a certain support for the expansion and contraction of the spring 10.

[0025] The stopper 11 is in the shape of a truncated cone and the small diameter end of the stopper 11 is opposite to the small diameter end of the tapered portion 4. When the large diameter end of the stopper 11 is against the inner wall of the tapered portion 4, the second medicine outlet 8 is located between the stopper 11 and the small diameter end of the tapered portion 4. When the liquid medicine in the syringe 1 is pushed by the piston 2, the liquid medicine has a pushing force on the stopper 11. The stopper 11 is in the shape of a truncated cone and the small diameter end is opposite to the small diameter end of the tapered portion 4. The liquid medicine will flow to the inclined surface of the stopper 11 and pass through the gap between the stopper 11 and the inner wall of the tapered portion 4. When the liquid medicine is pushed stably, the stopper 11 is also subjected to the elastic force of the spring 10, so that the force on the stopper 11 remains balanced.

[0026] When the medicine pushing speed increases, the impact force of the medicine on the block 11 increases, overcoming the elastic force of the spring 10. The block 11 moves and counteracts the inner wall of the conical portion 4. The medicine can no longer be discharged into the medicine outlet 5 through the second medicine outlet hole 8, thereby preventing the child from choking due to excessive medicine pushing speed.

[0027] In another embodiment of the present invention, Figure 2 As shown, the end of the syringe 1 is detachably connected to a fixed cover 14, and a push rod 3 is threadedly connected to the fixed cover 14, and the push rod 3 is fixed to the piston 2. Specifically, the fixed cover 14 is clamped on the end of the syringe 1 facing away from the tapered portion 4 or the side wall of the fixed cover 14 is bolted to the side wall of the syringe 1. As long as the fixed cover 14 is not directly screwed onto the end of the syringe 1, it can be avoided that the fixed cover 14 rotates with the rotation of the push rod 3. In order to avoid unstable air pressure in the syringe 1, an air hole 15 is opened on the fixed cover 14. In this embodiment, by rotating the push rod 3, the piston 2 is pushed to slide using the screw structure. Compared with directly pushing the piston 2 to slide, the rotation will increase some operational difficulty, thereby reducing the situation where the piston 2 is pushed too fast to a certain extent.

[0028] In another embodiment of the present invention, Figure 3 As shown, a through hole 16 is provided on the tapered portion 4 or the syringe 1, and a pressure relief valve is installed in the through hole 16. A flexible bag 17 is connected to the through hole 16. When the stopper 11 moves and hits the inner wall of the tapered portion 4, if the operator does not observe and continues to push the piston 2 to move, the stopper 11 is difficult to directly reset due to the pressure of the liquid medicine. At this time, the liquid medicine in the syringe 1 is difficult to discharge and can enter the flexible bag 17 through the through hole 16 under the action of pressure. The size change of the flexible bag 17 can assist the operator to find problems in time.

[0029] During the actual design process, a liquid pipe (not shown in the figure) can be connected between the flexible bag 17 and the medicine outlet nozzle 5, and a valve is installed in the liquid pipe. When the medicine liquid enters the flexible bag 17, the operator can open the valve and then squeeze the flexible bag 17 so that the medicine liquid in the flexible bag 17 enters the medicine outlet nozzle 5 through the liquid pipe, thereby avoiding waste of medicine liquid.

[0030] In another embodiment of the present invention, Figure 3 As shown, an arc-shaped medicine receiving cover 18 is fixed on the medicine dispensing nozzle 5. The medicine receiving cover 18 is made of silicone and is used to be stuck at the chin of the child. Even if the child spits out the unswallowed medicine, it can be received by the medicine receiving cover 18 to avoid it flowing onto clothes or flowing to other places that need to be handled.
