Referring to fig. 1-5, the present invention provides a technical solution:

the invention provides an anti-drop micro-adjustable valve infusion apparatus, which is provided with a connecting ring 2 and a micro-adjustable valve 3 in order to prevent an infusion tube from falling off due to stress and facilitate the control of the infusion speed of a special patient. Which comprises an infusion bottle 1 and a puncture outfit 10 inserted at the bottom of the infusion bottle, wherein an infusion tube 11 is inserted at the bottom of the puncture outfit 10. The bottom of the infusion bottle 1 is clamped with a connecting ring 2, and the bottom of the infusion tube 11 is connected with a micro-adjusting valve 3 with an ellipsoid structure. A bayonet 20 is arranged on one side of the connecting ring 2, so that the connecting ring 2 can be conveniently broken and clamped into the opening of the infusion bottle. The other side of go-between 2 and downwardly extending have an arc pole 21, and the bottom of arc pole 21 just is located go-between 2 and is equipped with the lantern ring 22 under, and lantern ring 22 cup joints with transfer line 11 and cooperates to puncture ware 10 is lived to vertical armoring. An oval inner cavity 300 is formed in the center of the rear end face of the fine adjustment valve 3 and used for circulation of liquid medicine. A plurality of scale marks 302 are arranged at the edge of the front end face of the fine adjustment valve 3 at equal intervals. The center of the front end face of the trim valve 3 is provided with a convex ring 301 communicated with the inner cavity 300, the inner cavity 300 is sleeved with a trim block 31 of an ellipsoid structure, the long axis length of the trim block 31 is equal to the short axis length of the inner cavity 300, so that the trim block 31 can divide the inner cavity 300 into two spaces. The knob 32 of cylinder structure is connected with in fine setting piece 31 preceding terminal surface center, and the interior terminal surface of knob 32 is close to the edge and has seted up ring channel 320, and ring channel 320 and bulge loop 301 joint cooperation, and still cup jointed the tourus of silica gel material between ring channel 320 and the bulge loop 301, play sealed effect, also bonded frictional force simultaneously, do benefit to knob 32 and stop at will. A sealing cover 33 is closely adhered to the rear end surface of the micro valve 3 to form a closed space in the inner chamber 300, so that the liquid medicine can flow through.

In this embodiment, the connection ring 2 and the fine adjustment valve 3 are made of PP material and have an integrally formed structure, which is light in weight, good in toughness, rigid in strength and not easy to break.

Further, the collar 22 is located below the puncture device 10, and the outer diameter of the collar 22 is smaller than the outer diameter of the puncture device 10, so as to pocket the puncture device 10 and ensure that the infusion bottle 1 and the puncture device 10 are connected without slipping.

Specifically, pipe sleeves 303 communicated with the inner cavity 300 are arranged on the outer side surfaces of the two ends of the short shaft of the fine adjustment valve 3, and the pipe sleeves 303 are tightly inserted and matched with the infusion tube 11, so that the liquid medicine flows into the inner cavity 300 of the fine adjustment valve 3.

Specifically, the number of the scale marks 302 in the short axis direction of the trim valve 3 is 0ml, the number of the scale marks 302 in the long axis direction of the trim valve 3 is 250ml, both ends of the long axis of the trim block 31 are required to correspond to both ends of the short axis of the inner chamber 300 when the trim block 31 is installed, and the flow rate is changed from 0ml to 250ml when the trim block 31 is turned to the horizontal position no matter left or right.

In addition, a square hole 310 is formed in the center of the end face of the fine adjustment block 31, a square block 321 is formed in the center of the inner end face of the knob 32, the square block 321 is in plug fit with the square hole 310, and an arrow-shaped projection 323 is formed in the outer end face of the knob 32, wherein the tip of the arrow faces the long axis end of the fine adjustment block 31, namely points to 0ml, so that the flow rate is increased gradually by looking at the scale mark 302.

It is worth noting that the dropper 12 is inserted in the middle section of the infusion tube 11 to facilitate observation of the dropping condition of the liquid medicine, the filter 13 is inserted in the middle section of the infusion tube 11 connected below the micro-adjustment valve 3 to filter the liquid medicine, and the puncture needle 14 is inserted in the bottom end of the infusion tube to puncture the blood vessel for infusion.

When the anti-drop micro-adjustable valve infusion apparatus of the utility model is used, the lantern ring 22 is firstly sleeved on the top of the infusion tube 11, the puncture outfit 10 is inserted on the top end of the infusion tube 11, and then the two ends of the bayonet 20 of the connecting ring 2 are broken off and clamped into the bottleneck of the infusion bottle 1, so that the puncture outfit 10 and the infusion bottle 1 are firmly connected; because the fine adjustment block 31 is installed in the inner cavity 300 in the original state that the long shaft end of the fine adjustment block is overlapped with the short shaft end of the inner cavity 300 to block the pipe sleeve 303, at this time, the tip of the bump 323 also points to the 0ml scale mark on the direction of the pipe sleeve 303, the fine adjustment block 31 is driven to rotate in the inner cavity 300 by rotating the knob 32 leftwards or rightwards, the long shaft of the fine adjustment block 31 gradually deviates from the pipe sleeve 303, so that the flow rate of the liquid medicine is gradually increased, and when the tip of the bump 323 points to the 250ml scale mark on the long shaft direction of the fine adjustment valve 3, the internal flow space of the inner cavity 300 is optimal.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
