Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1 and 2, the child precise medicine feeder comprises a medicine storage tube 2 and a plunger tube 13, wherein two connecting frames 9 are connected between the medicine storage tube 2 and the plunger tube 13. The outside of link 9 wraps up has rubber materials, the comfort when the multiplicable hand is held. The length of the medicine storage tube 2 is less than 10cm, the diameter of the section of the medicine storage tube 2 is less than 4cm, the whole capacity of the medicine storage tube is 8-25ml, and the medicine storage tube is convenient to carry. The line connecting the two connecting frames 9 intersects the axis of the plunger tube 13, i.e. the two connecting frames 9 are symmetrical with respect to the axis of the plunger tube 13. The two connecting frames 9 fix the medicine storage tube 2 and the plunger tube 13 into a whole. The axes of the medicine storage tube 2 and the plunger tube 13 are coincided. Store up the inside embedding of pencil 2 and plunger pipe 13 and have piston post 3, the upper end of piston post 3 is fixed with piston 11, and the inner wall of storage pencil 2 is glossy, piston 11 and the inner wall sliding connection who stores up pencil 2. The piston column 3 is not contacted with the medicine storage tube 2. End cover 1 is installed to the upper end of storage medicine pipe 2, and end cover 1 is the toper and is detachable, and storage medicine pipe 2 is fixed through threaded connection with end cover 1, installs the sealing washer between the two. The end cover 1 is provided with a medicine outlet end 12.
As shown in fig. 8, 9, 10, and 11, the medicine discharging end 12 includes a medicine discharging tube 1201, and the medicine discharging tube 1201 is embedded in an end surface of the medicine discharging end 12. The aperture of the medicine outlet pipe 1201 is 0.5mm-1mm, and the medicine outlet pipe 1201 is very thin, so a pipe sleeve 1202 is embedded outside the medicine outlet pipe 1201, and the pipe sleeve 1202 is made of soft rubber, so that the skin can be prevented from being scratched. A groove 1203 is formed between the pipe sleeve 1202 and the outer wall of the medicine outlet end 12, and due to the fact that adhesion force exists between liquid and the surface of a material, in order to prevent the medicine from being adhered to the end face of the medicine outlet end 12 after coming out of the medicine outlet pipe 1201, waste caused by the adhesion force of the medicine can be effectively avoided due to the design of the groove 1203, and in addition, the medicine administration precision is greatly improved. The medicine outlet end 12 is provided with a chamfer 1204, which can prevent the skin from being scratched by edges and corners and make the exterior lines more beautiful.
As shown in fig. 3, 4, 5 and 6, an adjusting ring 5 is embedded outside the piston column 3, and the adjusting ring 5 is located between the drug storage tube 2 and the plunger tube 13. The outside of piston post 3 is provided with external screw thread 4, and the inside of adjustable ring 5 is provided with internal thread 8, and external screw thread 4 and internal thread 8 looks adaptation. The adjusting ring 5 is externally provided with frosted lines 17 suitable for manually rotating the adjusting ring 5. At least one slider 10 is installed to the lower extreme of piston post 3, is provided with at least one constant head tank 14 on the inner wall of plunger pipe 13, and slider 10 imbeds in the inside of constant head tank 14, slider 10 and constant head tank 14 sliding connection. Preferably, the number of the sliders 10 is two, and a connecting line between the two sliders 10 intersects with the axis of the piston post 3, i.e., the two sliders 10 are symmetrical about the axis of the piston post 3. The number of the positioning grooves 14 is the same as that of the sliders 10, and the positioning grooves 14 are parallel to the axis of the piston column 3. When the adjusting ring 5 is rotated, the piston column 3 can be pushed to move axially by the axial acting force between the threads, and because the slider 10 is embedded in the positioning groove 14, the radial acting force between the threads is offset, so that the radial positioning of the piston column 3 is ensured, and the accuracy of the axial movement of the piston column 3 when the adjusting ring 5 is rotated is also ensured. The outside of the adjusting ring 5 is provided with a scale mark 16, and the outside of the plunger tube 13 and the medicine storage tube 2 are both provided with a standard line 15 which is suitable for reading the numerical value of the scale mark 16. The scale value of the scale mark 16 can be obtained according to the internal sectional area of the medicine storage tube 2 and the thread pitch, for example, the thread pitch moved when the adjusting ring 5 rotates for one circle is the axial distance moved by the piston 11, the product of the distance and the internal sectional area of the medicine storage tube 2 is the dosage when the adjusting ring 5 rotates for one circle, and then the volume is equally divided into the volume of each angle. Since the pitch of the threads is usually small and the angle of rotation of the adjustment ring 5 is well controlled, the accuracy is high when controlling smaller doses.
As shown in fig. 3 and 7, a first thrust bearing 6 is mounted between the adjusting ring 5 and the drug storage tube 2, and the first thrust bearing 6 is respectively abutted against the adjusting ring 5 and the drug storage tube 2. A second thrust bearing 7 is installed between the adjusting ring 5 and the plunger pipe 13, and the second thrust bearing 7 is respectively abutted against the adjusting ring 5 and the plunger pipe 13. When the adjusting ring 5 is rotated, the upper thrust bearing and the lower thrust bearing are abutted and clamped, so that the adjusting ring 5 cannot move up and down, and the moving precision of the piston column 3 is ensured. In addition, when the adjusting ring 5 is rotated, the two thrust bearings can ensure that the adjusting ring 5 rotates smoothly, and large friction force generated during radial rotation is avoided.
When using this accurate ware of dosing of children, rotatory adjustable ring 5 can promote piston post 3 along axial displacement through the axial force between the screw thread to promote the liquid medicine in the storage medicine pipe 2 through piston 11, extrude out medicine end 12 with the liquid medicine, because slider 10 imbeds in the inside of constant head tank 14, the radial force between the screw thread is offset, has guaranteed the radial positioning of piston post 3, 3 axial displacement's of piston post accuracy when also having guaranteed rotatory adjustable ring 5 simultaneously. The outside of adjustable ring 5 is provided with scale mark 16, plunger pipe 13 all is provided with standard line 15 with the outside of medicine storage tube 2, be suitable for reading the numerical value of scale mark 16, can know the dose through reading the scale value, because the screw thread interval is less usually, and the better control of the rotatory angle of adjustable ring 5, turn into axial displacement with radial rotation, consequently the accuracy is higher when controlling less dose, the minimum scale can be accurate to 0.1ml, the security is higher, can not cause the injury to children at the in-process of dosing. Because two thrust bearings are used for clamping the piston column, the adjusting ring 5 cannot move up and down, the moving precision of the piston column 3 is ensured, and the smoothness of the adjusting ring 5 during rotation is also ensured. The accurate medicine feeder for children is convenient to use, accurate in medicine amount control, convenient to carry, safer and low in cost.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
