In this embodiment, the first insertion region 111, the second insertion region 112, and the third insertion region 113 are provided in the insertion portion 11, and the first administration region 211, the second administration region 212, and the third administration region 213 are provided in the piston 2, respectively corresponding to the insertion position and the administration position of a newborn, an infant, and an infant. Taking the neonate as an example, the insertion part stays in the first insertion region 111 and the piston is pushed into the first administration region 211 according to the cross-sectional area S of the tube1And the cross-sectional area of the drug storage tube 12 is S2And the length of each extending area and each administration area is applied by the formula V1=lg1·S2-(lS1+lS2+lS3)·S1Calculating, here, the length l of the first run-in region 111S1Is determined according to the conventional range of the newborn, and the actual required enema dosage is V because a part of medicament is remained in the tube body of the stretching part after medicament pushing1. For simplicity of calculation, the first scale, the second scale and the third scale may be set in milliliters, and the same color may be marked on the first protruding region 111 and the first administration region 211, the second protruding region 112 and the second administration region 212 according to a calculated formulaThe same colour is marked, the same colour is marked on the third stretching-in area 113 and the third dosing area 213, such as red, yellow and blue, when enema, only the infant needs to be inserted into the corresponding stretching-in area according to the age of the infant, and the infant is pushed into the corresponding dosing area. The operation method of the infant patient is similar to that of the infant patient, and the details are not repeated herein.
Further, the extending part 11 is detachably connected with the medicine storage tube 12; the medicine storage tube 12 is provided with a convex column which can be embedded into the tube body of the extending part 11 in a matching way.
In this embodiment, draw out the medicament through the projection on the medicine storage tube 12 earlier, will stretch into the portion cover on the projection again, insert and stretch into portion 11 to the corresponding district that stretches into, promote piston 2 to the corresponding district of dosing, this structure can draw out the medicament more fast, prevents the secondary pollution of medicament.
Unlike the previous embodiment, the inlet 11 and the drug storage tube 12 are of an integral structure.
In this embodiment, the design of the integrated structure of the inlet portion 11 and the drug storage tube 12 can extract the drug from the drug outlet hole on the tube body, if the drug dose is to be saved, the position of the drug corresponding to the first scale in the drug storage tube 12 can be observed at any time in the extraction process, and the drug can be stored according to the V1、V2And V3The amount of (c) is equal to or greater than the scale. The piston 2 can also be directly pulled to the preparation position, so that the medicine in the medicine storage tube is sufficient.
Further, an annular elastic sheet 122 is arranged on the inner wall of the medicine storage tube 12 near the through hole end, and an annular positioning groove 22 for the annular elastic sheet to be matched and embedded is arranged at a predetermined unit in the third scale of the piston 2.
In this embodiment, for extracting the medicament and advancing the medicament more accurately, piston 2 slides the in-process in storing up pencil 12, when sliding to the position of setting for, annular shell fragment 122 can match during embedding annular positioning groove 22, sets up this damping and can remind medical personnel, and annular positioning groove 22 on piston 2 here can set up a plurality ofly, if can set up in whole scale position, can set up the boundary department in two district of dosing, also can set up in other positions as required.
Further, a plurality of medicine outlet holes 114 on the tube body are cross openings.
In this embodiment, the crossed openings are arranged on the tube body to prevent the tube from being blocked when the drug is pushed, so that discomfort is caused to the infant patient.
