Description

Technical Field

[0001] The present application relates to the technical field of pediatric nursing medicine feeders, and specifically discloses a pediatric nursing medicine feeder. Background Art

[0002] After birth, children are in close contact with nature, and they often become ill due to various reasons. Drug therapy is an important step in the comprehensive measures to prevent and treat diseases. In the process of pediatric care, children need to be fed medicine. In order to make it easier for children to take the medicine, the tablets are often crushed and converted into liquid medicine for children to take. The principle of pediatricians is that if the medicine can be taken orally, it should not be injected intramuscularly; at the same time, if the medicine can be injected intramuscularly, it should not be injected intravenously. Therefore, oral feeding is the first choice for treating diseases.

[0003] However, some pediatric wards have young children. Due to the need for treatment, they are often treated with a variety of drugs. Children of different age groups have different characteristics. Therefore, in order to ensure that the various drugs can achieve the best therapeutic effect after taking them, nurses must do a good job of placing and feeding the drugs. However, most of the current tablets are crushed by external objects and then converted into liquid medicine for children to take;

[0004] In this process, the ground medicine needs to be mixed with hot water. In this process, there are too many things to consider: for example, the hot water does not meet the feeding temperature and needs to be cooled down; for example, insufficient grinding leads to the formation of a solid-liquid mixture, which does not meet the feeding standard; the flow rate of the feeding liquid cannot be controlled, which is easy to choke the medicine and does not meet the feeding standard; after the quantitative hot water is added, the amount of hot water cannot be accurately controlled, and skilled nurses are needed to achieve non-feeling feeding;

[0005] The above requirements or complicated procedures make it more difficult for medical staff to feed medicine to children. In view of this, the inventor proposes a pediatric nursing medicine feeder. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that the traditional pediatric nursing medicine feeder has increased difficulty in feeding medicine to children due to the complicated medicine feeding standards or medicine feeding operation steps.

[0007] In order to achieve the above object, the present invention provides the following basic scheme:

[0008] A pediatric nursing medicine feeder, comprising a grinding cylinder, a stirring liquid discharging cylinder detachably connected to one end of the grinding cylinder, a connecting portion detachably connected to the stirring liquid discharging cylinder, a hose connected to the connecting portion, an infusion tube connected to the hose, an end cap detachably connected to the other end of the grinding cylinder, and a collecting cylinder arranged on the end cap and detachably connected to the end cap;

[0009] The grinding cylinder is provided with a grinding assembly for grinding solid drugs into powder and a filter for screening drug particles from top to bottom.

[0010] The grinding assembly cooperates with the built-in cylinder to grind the solid medicine into powder step by step.

[0011] The principles and effects of this basic solution are:

[0012] 1. Compared with the prior art, the device has a simple structure and an ingenious design. First, the device is suitable for feeding solid medicines with water and for mixing multiple medicines with water. Multiple medicines and water can be put in separately and then mixed after uniform stirring. It can be operated by one person, solving the problem that traditional pediatric nursing medicine feeders have increased difficulty in feeding medicine to children due to complicated medicine feeding standards or operation steps.

[0013] 2. Compared with the prior art, this device has an advantage in insufficient grinding: since the core issue of solid medicines being mixed with water for feeding is how to deal with the solid medicines, this device still adopts the method of grinding into powder to fully mix with water, but this device grinds into powder more fully, and is provided with preliminary grinding, particle grinding and fine grinding links to achieve more complete grinding into powder, and is provided with a filter to filter out large particles to avoid the foreign body sensation caused by children feeding, and the grinding action of grinding into powder is utilized to accelerate the mixing of the medicine with water after the medicine is powdered, that is, accelerate the formation of liquid medicine.

[0014] 3. Compared with the prior art, the device has the advantage that the flow rate of the drug feeding liquid cannot be controlled: the device is designed with an infusion tube, and a medical-grade infusion tube is used as the feeding tube. The slender characteristics of the infusion tube are utilized to realize that the liquid passing through the infusion tube can be artificially controlled. Therefore, an extrusion area is designed on the surface of the infusion tube, and the flow rate is reasonably controlled by the extrusion area, thereby realizing that the device can reasonably control the flow rate of the drug feeding liquid.

[0015] 4. Compared with the prior art, the present device has the advantage that the amount of hot water cannot be accurately controlled after a certain amount of hot water is added. The present device first realizes that multiple medicines and water can be added separately and then mixed after uniform stirring. Since multiple medicines and water can be added separately, a collecting cylinder is specially designed for the water input. The collecting cylinder is used to receive the water injected by the syringe, and the water drawn by the syringe can be manually quantified. In this way, the present device can realize accurate control of the amount of hot water after a certain amount of hot water is added.

[0016] 5. Compared with the existing technology, this device has advantages in non-contact feeding of medicine: this device uses a medical infusion tube as a feeding tube, and takes advantage of the slender characteristics of the infusion tube, which can be conveniently placed near the child's mouth to achieve feeding. This feeding method can minimize the child's resistance and achieve non-contact feeding.

[0017] 6. Compared with the prior art, the present device has an advantage in the feeding temperature of the medicine liquid: due to the difference between the child's body temperature and the mixed temperature of the medicine liquid and hot water, some medicines may require not only heating but also cooling. Therefore, in order to achieve better non-inductive feeding, the present device is provided with a portable heating and cooling bag on the periphery of the mixing barrel, and the portable heating and cooling bag is used to achieve heating or cooling, and the thermal conductivity of the mixing barrel is used to achieve heating or cooling of the mixing barrel, so as to achieve the temperature of the liquid subsequently released from the mixing barrel to be close to the temperature felt by the child, thereby achieving non-inductive feeding for the child.

[0033] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0034] The figure marks in the drawings of the specification include: infusion tube 1, extrusion area 2, hose 3, connecting part 4, connecting slot 5, switch valve 6, external thread 7, liquid outlet pipe 8, stirring liquid outlet cylinder 9, annular groove 10, thermometer 11, grinding cylinder 12, filter screen 13, mounting hole 14, built-in cylinder 15, end cover 16, connecting port 17, connecting column 18, rubber sleeve 19, collecting cylinder 20, battery pack 21, magnet group 22, sleeve ring package 23, heating part 24, cooling part 25, grinding rod 26, material guide initial grinding part 27, extrusion surface 28, receiving part 29, fine grinding part 30, arc surface 31, follower rod 32, grinding disc 33, lower cylinder 34, rotating part 35, bearing 36, stirring rod 37, and input port 38.

[0035] Implementation example Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown:

[0036] A pediatric nursing medicine feeder, comprising a grinding cylinder 12, a stirring liquid discharging cylinder 9 detachably connected to the lower end of the grinding cylinder 12, a connecting portion 4 detachably connected to the stirring liquid discharging cylinder 9, a hose 3 connected to the connecting portion 4, an infusion tube 1 connected to the hose 3, an end cap 16 detachably connected to the upper end of the grinding cylinder 12, and a collecting cylinder 20 disposed on the end cap 16 and detachably connected to the end cap 16;

[0037] About the collecting tube 20: the collecting tube 20 is threadedly connected to the end cover 16, a connecting column 18 is provided at the bottom of the collecting tube 20, the connecting column 18 is threadedly connected to the end cover 16, the collecting tube 20 is a hollow tube used to observe the water flow and a rubber sleeve 19 is provided on the top of the collecting tube 20, the needle can penetrate the rubber sleeve 19 to inject water into the collecting tube 20.

[0038] The rubber sleeve 19 is mainly used for dust prevention and can be easily pierced by a syringe with a needle. Since the needle and the syringe are conventionally matched, the water injection capacity can be determined by the scale line of the syringe, and the water can be accurately quantified.

[0039] About the hose 3: The hose 3 is connected to the infusion tube 1. The hose 3 is mainly used to increase the range of movement of the device. On the infusion tube 1, squeezing areas 2 are provided on both sides of the infusion tube 1. The surface roughness of the squeezing areas 2 is greater than the surface roughness of the infusion tube 1. The infusion tube 1 is selected because of its slender characteristics. Combined with the hose 3, it can be conveniently placed near the child's mouth to achieve feeding. For children, this feeding method can minimize the resistance of children and achieve non-sensing feeding.

[0040] In terms of overall structure:

[0041] Both ends of the grinding cylinder 12 are threaded structures, and the threaded structures are used to achieve a detachable connection between the end cap 16 and the stirring and discharging cylinder 9;

[0042] The grinding cylinder 12 is provided with a grinding assembly for grinding solid medicine into powder and a filter 13 for screening medicine particles from top to bottom.

[0043] About the grinding in this case:

[0044] An inner cylinder 15 is provided inside the grinding cylinder 12, and the inner cylinder 15 includes an upper cylinder and a lower cylinder 34 connected to the upper cylinder, the inner diameter of the upper cylinder is larger than the inner diameter of the lower cylinder 34, and the grinding assembly includes a grinding rod 26, a rotating part 35 arranged at the upper end of the grinding rod 26, a material guiding initial grinding part 27 arranged around the lower end of the grinding rod 26 in sequence, a receiving part 29 for receiving solid medicine, a fine grinding part 30 arranged at the bottom of the receiving part 29 and used in conjunction with the inner bottom surface of the upper cylinder, and a grinding disc 33 arranged around the grinding rod 26 located inside the lower cylinder 34, and the grinding disc 33 is used in conjunction with the inner wall of the lower cylinder 34;

[0045] The material guiding and initial grinding part 27 is provided with a material guiding inclined surface and an extrusion surface 28. The extrusion surface 28 cooperates with the upper tube to extrude the solid medicine. The outer diameter of the receiving part 29 is larger than the outer diameter of the material initial grinding part and smaller than the inner diameter of the upper tube. The inner bottom surface of the upper tube is an arc surface 31, and the fine grinding part 30 is an arc block with the same curvature as the arc surface 31.

[0046] Specifically, the end cover 16 is provided with an input port 38 and a connection port 17. The connection port 17 is used for connecting the grinding rod 26. The solid medicine is directly input into the input port 38. Since the outer diameter of the receiving portion 29 is larger than the outer diameter of the material initial grinding portion and smaller than the inner diameter of the upper cylinder, the solid medicine is forced to stay. Then, the rotating portion 35 is manually rotated, and the solid medicine is squeezed and ground by the material guiding initial grinding portion 27 and enters the bottom of the upper cylinder. Then, it is ground again by the fine grinding portion 30, and the medicine enters the lower cylinder 34. As the rotating portion 35 rotates, the grinding disc 33 rotates. Based on the rotation of the grinding disc 33, the medicine is ground into powder.

[0047] The grinding assembly cooperates with the built-in cylinder 15 to grind the solid medicine into powder step by step. The grinding assembly is a collection of the grinding rod 26, the rotating part 35, the material guiding initial grinding part 27, the receiving part 29, the fine grinding part 30 and the grinding disc 33.

[0048] In this process: there may still be large particles, which may cause discomfort to children when fed. Therefore, a filter 13 is designed. Regarding the filter 13, since the powder flowing out of the lower cylinder 34 is not dispersed enough, the screening effect of the filter 13 cannot be fully exerted. Therefore, a follower rod 32 for powder drug dispersion is provided below the fine grinding part 30 of the grinding rod 26. When the rotating rod rotates, the follower rod 32 rotates accordingly. The follower rod 32 generates a certain centrifugal force, so that the drug powder can be dispersed around the filter 13, and the screening effect of the filter 13 can be fully utilized. For the stability of the filter 13, a bearing 36 is provided below the follower rod 32 located at the fine grinding part 30. A mounting hole 14 is opened in the center of the filter 13, and the bearing 36 is installed with the filter 13 through the mounting hole 14. This design is to ensure that the stability of the filter 13 is not affected when the grinding rod 26 rotates.

[0049] After the drug powder passes through the filter screen 13, it falls into the stirring liquid outlet cylinder 9. At this time, the collecting cylinder 20 needs to be injected with water so that the water also falls into the stirring liquid outlet cylinder 9, and then the grinding rod 26 is rotated. The main purpose of this step of rotation is to achieve stirring and mixing of the drug liquid, and the secondary purpose is to grind some stuck solid drugs for the second time to ensure that the amount of the drug will not be too much error;

[0050] Specifically: A stirring rod 37 is provided at the bottom of the grinding rod 26, and the stirring rod 37 passes through the grinding cylinder 12 and is located in the stirring liquid outlet cylinder 9. An annular groove 10 is installed on the outer periphery of the stirring liquid outlet cylinder 9, and a liquid outlet pipe 8 is connected to the bottom of the stirring liquid outlet cylinder 9. A switch valve 6 is provided on the liquid outlet pipe 8, and the liquid outlet pipe 8 is detachably connected to the connecting part 4.

[0051] The switch valve 6 is used to stir and mix the liquid medicine. In this process, there is a problem: the mixing temperature of the medicine does not match the feeding temperature, which may cause discomfort to children. Therefore, cooling or heating is required:

[0052] Specifically: This case designs a portable heating and cooling pack based on this pain point problem;

[0053] Regarding the portable heating and cooling pack: it also includes a portable heating and cooling pack that is detachably connected to the ring groove 10, the portable heating and cooling pack includes a battery pack 21 and a ring pack 23, the ends of the ring pack 23 are magnet groups 22 that can be magnetically connected to each other, the inner wall of the ring pack 23 that contacts the inner wall of the ring groove 10 is a heating part 24 and a cooling part 25, the heating part 24 is a resistance wire heating group, the cooling part 25 is a cooling plate, and the cooling surface of the cooling plate is in contact with the inner wall of the ring groove 10.

[0054] Specifically: the heating part 24 and the cooling part 25 are used to heat or cool the drug liquid stirring mixture respectively. A thermometer 11 is provided on the stirring liquid discharge cylinder 9. The temperature data is obtained by using the thermometer 11, and then the most appropriate feeding temperature is adjusted to achieve the matching of the feeding temperature with the drug stirring and mixing temperature, thereby solving the problem of mismatch between the drug stirring and mixing temperature and the feeding temperature.

[0055] Structurally: the outer periphery of the liquid outlet pipe 8 is provided with an external thread 7, the inner wall of the connecting portion 4 is provided with an internal thread that can be threadedly connected to the external thread 7, and a connecting groove 5 is opened on the outer periphery of the connecting portion 4, and a clamping ring is sleeved on the connecting groove 5.

[0056] Specifically: Although it is a threaded connection, there may be a problem of leakage. Therefore, in order to avoid this defect problem, the present invention designs a connecting slot 5 and a clamping ring, and the clamping ring is installed on the connecting slot 5 to strengthen the connection of the liquid outlet pipe 8;

[0057] The reason why the liquid outlet tube 8 is designed is that due to the material limitation of the infusion tube 1 and the hose 3, a hardware is needed to realize the connection, thus the liquid outlet tube 8 is designed;

[0058] Specific implementation process:

[0059] The first step is to put the solid medicine into the input port 38, and grind it into powder under the action of the grinding assembly and stay in the stirring and liquid discharging cylinder 9;

[0060] In the second step, a certain amount of water is injected through the collecting tube 20, and the water stays in the stirring and discharging tube 9, and then the grinding assembly is used to achieve mixing and stirring of the liquid medicine. After the mixing and stirring is completed, the temperature is controlled by a portable heating and cooling bag, and then the switch valve 6 is opened, and the liquid medicine enters the hose 3 and the infusion tube 1;

[0061] In the third step, the medical staff places the end of the infusion tube 1 near the child's mouth and uses the squeezing area 2 to control the flow rate to complete the feeding of the liquid medicine.

[0062] The device solves the problem that the traditional pediatric nursing medicine feeder increases the difficulty of medical staff in feeding medicine to children due to the complicated medicine feeding standards or medicine feeding operation steps.

[0063] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
