Ask for an interview Fig. 3 and continuation in conjunction with Fig. 1 and Fig. 2, aforesaid discharge nozzle 13 is connected with drain pipe and all is connected with the switching valve 3 that Fig. 3 is shown in detail, this switching valve 3 preferably but not the structure that definitely is limited to is as follows: comprise valve body 31, spool 32, first, the second interface 33,34 and go out liquid interface 35, valve body 31 is fixed on the outer wall by the pump housing of the infusion pump 7 of Fig. 1 and Fig. 3 signal, spool 32 is arranged in the valve pocket of valve body 1 rotationally, and be connected with infusion pump 7, spool 32 consist of have into, go out sap cavity 321,322 and diversion cavity 323, wherein: diversion cavity 323 be positioned at into, go out sap cavity 321, between 322, first interface 33 and the second interface 34 are formed on the outer wall of valve body 31 with the state extension that sticks together each other, and all the valve pocket with valve body 31 communicates, go out liquid interface 35 same extensions and be formed on the outer wall of valve body 31, and communicate with valve pocket.Above mentioned discharge nozzle 31 connects with first interface 33, and drain pipe 23 and the second interface 34 connect, an end of crowded liquid pipe 4 illustrated in figures 1 and 2 and go out liquid interface 35 and connect, and the other end and the following adapter that also will describe in detail 5 connect.

The effect of having taken in fact machine-tool by the infusion pump 7 of Fig. 1 signal, this infusion pump 7 has a transaxle 71 and a pump dise axle 72, the end of transaxle 71 consists of has one to connect boss 711, this connects the hole of boss 711 on the pump housing and is stretched over outside the pump housing, aforesaid spool 32 connects chamber 324(Fig. 3 and shows towards an end of infusion pump 7 and offering a boss corresponding to the position that connects boss 711), this boss connects chamber 324 and connects boss 711 and connects, and that is to say that connecting boss 711 is placed in the boss mating cavity 324.By shown in Figure 3, the side on aforesaid first interface 33 and the second interface 34 jointly consists of handgrip 36.

Under the clockwise or counterclockwise rotation of transaxle 71, can make spool 32 clockwise or be rotated counterclockwise certain angle by connecting boss 711.For example when spool 32 turns clockwise an angle, aforementioned admission chamber 321 is just corresponding with the tube chamber of discharge nozzle 13, thereby entered in the valve pocket of valve body 31 by the nutritional solution that discharge nozzle 13 is drawn, so through diversion cavity 323, go out sap cavity 322 and valve pocket fairlead 311 and introduce the aforesaid liquid interface 35 that goes out.Otherwise, when spool is rotated counterclockwise an angle, aforesaid admission chamber 321 is corresponding with the tube chamber of drain pipe 23, thereby is entered in the valve pocket of valve body 31 by the cleaning solution that drain pipe 23 is drawn, so through diversion cavity 323, go out sap cavity 322 and valve pocket fairlead 311 and introduce the aforesaid liquid interface 35 that goes out.

By illustrated in figures 1 and 2, owing to be connected with and have the end that elastic and material is preferably the crowded liquid pipe 4 of plastic tube or rubber tube (silicone rubber tube) going out liquid interface 35, therefore come from the nutritional solution of liquid interface 35 or cleaning solution through squeeze liquid pipe 4 and again the adapter 5 through connecting at the other end that squeezes liquid pipe 4 enter outlet tube 6, flow to the feeding tube that is inserted in the patient body by outlet tube 6, the joint 61 of feeding tube and outlet tube 6 connects.

By shown in Figure 1, consisting of at the outer wall of infusion pump 7 has crowded liquid pipe stopper slot 73 and adapter stopper slot 74, aforesaid crowded liquid pipe 4 to be embedded in to squeeze in the liquid pipe stopper slot 73, and aforesaid adapter 5 is embedded in the adapter stopper slot 74.

Ask for an interview Fig. 4, provide the detailed construction of adapter 5, be extended with one first connection-peg 51 in a side of this adapter 5, and opposite side has been extended with one second connection-peg 52, aforesaid crowded liquid pipe 4 and the first connection-peg 51 connect, and aforesaid outlet tube 6 and the second connection-peg 52 connect.Preferred scheme also can be nested with one first cushion pad 511 at the first connection-peg 51, and is nested with one second cushion pad 521 at the second connection-peg 521.

See also Fig. 5 and continuation in conjunction with Fig. 1, the material of Fig. 5 signal squeezes and send mechanism of animals 8 to be fixedly arranged on the aforesaid pump dise axle 72, this material squeezes and send mechanism of animals 8 to comprise that first, second connects 81,82 and one groups of pressure rams 83 of dish, first, second connects dish 81,82 and faces each other and cooperate and preferably be fixed on the pump dise axle 72 with flat key, the quantity of one group of pressure ram 83 is preferably three, and with equidistant intervals be fixed on first, second connect the dish 81,82 between.By shown in Figure 5, three pressure rams 83 center on first, second circumferencial direction that connects dish 81,82 respectively with 120 ° of intervals.The middle part of aforesaid crowded liquid pipe 4 is nested with on pressure ram 83.Under the motion (rotation) of pump dise axle 72, drive first, second and connect dish 81,82 rotations, pressure ram 83 rotates simultaneously, in pressure ram 83 rotary courses, apply active force to squeezing liquid pipe 4, drive towards the direction of outlet tube 6 thereby will enter into the nutritional solution or the cleaning solution that squeeze in the liquid pipe 4.

The applicant sketches use of the present utility model, through charge door 12 to the nutrient bag chamber 11 interior introducing nutritional solutions and build charge door gag 121, through filling opening 22 to cleaning solution bag chamber 21 interior introducing cleaning solutions and build filling opening gag 221.When to patient's feeding nutritional solution, the boss 711 that connects by the transaxle 71 of infusion pump 7 rotates an angle with the spool 32 of switching valve 3 to clockwise direction, make admission chamber 321 corresponding with first interface 33, the nutritional solution that comes from discharge nozzle 13 enters the valve pocket of valve body 31, successively through diversion cavity 323, go out sap cavity 322 and valve pocket fairlead 311 enters out liquid interface 35, and then enter crowded liquid pipe 4, enter into the nutritional solutions that squeeze in the liquid pipe 4 and under the driveing of pressure ram 83, enter tube for transfusion 6.When after pausing for patient's feeding nutritional solution, needing to introduce cleaning solution, then rotate an angle by pump dise axle 72 to counter clockwise direction, make admission chamber 321 corresponding with the second interface 34, the cleaning solution that comes from drain pipe 23 enters the valve pocket of valve body 31, and is identical with top description and until enter outlet tube 6.Generally, be that 24h changes nutrient bag 1 and cleaning solution bag 2 every day, and switching valve 4, crowded liquid pipe 4, adapter 5 and outlet tube 6 are in company with changing.

In sum, the technical scheme that this utility model provides has overcome the shortcoming in the prior art, has successfully finished the invention task, has embodied due technique effect
