All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a replaceable infusion device, which comprises an infusion tube 1, wherein the infusion tube 1 is connected with an adjusting box 2 with an adjusting cavity at the center, two liquid inlet holes are formed in the upper end surface of the adjusting box 2, two liquid outlet holes are correspondingly formed in the bottom surface of the adjusting box, an adjusting valve 3 is arranged in the adjusting cavity, two infusion through holes 4 are formed in the adjusting valve 3, each liquid inlet hole is communicated with an infusion hole corresponding to the liquid inlet hole through the infusion through hole 4, an adjusting handle 5 is arranged at the center of the adjusting valve 3, an adjusting groove 6 is formed in the adjusting box 2, the adjusting handle 5 penetrates through the adjusting groove 6 and is positioned on the outer side of the adjusting box 2, and the liquid inlet holes and the infusion holes are respectively externally connected with the infusion tube 1.

The lower extreme of regulation handle 5 is equipped with telescopic link 7, telescopic link 7 is close to the one end of regulation handle 5 is equipped with limit buckle 8, the other end of telescopic link 7 is fixed on governing valve 3, be equipped with a plurality of position fixed slots (5 shown in fig. 1) that are used for fixing limit buckle 8 on adjustment tank 6.

The junction between feed liquor hole and infusion hole and the transfer line is equipped with connector 9, connector 9 includes hollow cylindrical joint pipe 10 and buckle cover 11, the one end tip of joint pipe 10 is equipped with tapered end 12, buckle cover 11 can overlap on the tapered end 12, the other end of joint pipe 10 with 2 threaded connection of regulating box, be equipped with buckle floor 13 on the lateral wall of joint pipe 10, the one end of buckle floor 13 is equipped with and is used for fixing the pothook 14 of buckle cover 11, the other end of buckle floor 13 articulates has the fixing base 15 of U-shaped just buckle floor 13 can be followed fixing base 15 rotates, fixing base 15 is fixed on the joint pipe 10.

The end parts of different infusion tubes are inserted into the conical end head 12, after the initial fixation, the buckle sleeve 11 slides, and the end parts of the infusion tubes are tightly fixed at the two ends of the joint tube 10 along with the diameter increase of the conical end head 12.

A fixing plate 16 is further arranged between the fixing seat 15 and the joint pipe 10, the fixing plate 16 is fixed on the outer side wall of the joint pipe 10, a waist hole 17 is formed in the fixing plate 16, and the fixing seat 15 is fixed on the fixing plate 16 through the waist hole 17 in a screw mode. According to the transfer line of different specifications, under the certain condition of buckle floor 13 length, the position of nimble removal fixing base 15 guarantees the fixed stability of transfer line tip, and the flexibility of use of device obtains guaranteeing.

And the outer side wall of the conical end head 12 is provided with an anti-skid surface. The setting of antiskid face prevents effectively that buckle floor 13 from sliding along the wedge face of toper end 12 and causing not hard up, further guarantees the reliability of fixed position.

A plurality of catching grooves 18 are formed in the hinged position of the fixing seat 15 and the catching rib plate 13, and position fixing buckles 19 matched with the catching grooves 18 for use are arranged on the catching rib plate 13. When the snap rib 13 is rotated to fix the snap sleeve 11, the position fixing hook 19 enters the hook groove 18 to prevent the snap rib 13 from slipping off every time it is rotated to an angle.

One end of one of the conical ends 12 is fixed with a filter membrane 20. Impurities brought by the preparation of the transfusion liquid medicine are reduced through the filtering membrane 20, and the transfusion safety of a patient is ensured. The inside wall of the conical end head 12 is provided with an annular bulge 21, the outside wall of the filtering membrane 20 is provided with a groove matched with the annular bulge 21, and the conical end head 12 is flush with one end of the filtering membrane 20. The filtering membrane 20 is embedded in the conical head 12 through the matching of the annular bulge 21 and the groove between the filtering membrane 20 and the conical head 12.

The working principle is as follows:

when the infusion tube is connected, the clamping sleeve 11 is firstly sleeved in the end pipeline of the infusion tube 1, then the clamping sleeve 11 is pulled back in the end pipeline inserted into the conical end 12 of the infusion tube 1, the clamping sleeve 11 is tightly buckled on the rough anti-skidding surface of the conical end 12, the clamping rib plate 13 is rotated, the clamping hook 14 of the clamping rib plate 13 is tightly hooked at one end, far away from the clamping rib plate 13, of the clamping sleeve 11, and the fixation is completed.

The position of the adjusting box 2 is adjusted by the adjusting handle 5: pull up adjustment handle 5, telescopic link 7 is elongated, and pulling adjustment handle 5 about spacing knot 8 breaks away from the position fixed slot on the adjustment tank 6 (according to this embodiment shown in fig. 1), makes 4 intercommunication feed liquor holes of one of them infusion and the infusion hole rather than corresponding, then with 8 calories of buckles of spacing knot on the telescopic link, the spacing knot also is located the position fixed slot on the adjustment tank 6 this moment in, plays the fixed action, prevents 2 horizontal slideings of regulating box. When the infusion tube 1 corresponding to the liquid inlet hole is started, if the infusion tube is positioned at the leftmost end, the infusion tube at the left side is used for infusion, if the infusion flow rate needs to be reduced, the infusion tube is adjusted to the position fixing groove only close to the right side according to the same method, and if the infusion tube needs to be stopped completely at the same time, the infusion tube at the two sides stops infusion only by adjusting the position of the adjusting handle 5 to the position fixing groove (the position fixing groove in the middle shown in fig. 2) in the middle of the adjusting groove 6. The transfusion pipeline is convenient and quick to adjust, the infection probability of the outside to the transfusion liquid medicine is reduced, and the transfusion device is safe and convenient.

The position of the buckle rib plate 14 is flexibly adjusted through the waist hole 17, so that the clamping fixing positions (namely the force application positions of the clamping hooks 14) of the buckle rib plates 13 are positioned on the same circumference.

When the filtering membrane 20 is fixed on the conical end head 12, the filtering membrane 20 is only required to be placed on one side of the conical end head 12, the sterilized cotton or the medical protective membrane is padded, and the filtering membrane 20 is clamped on the conical end head 12 through forced pressing.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
