Abstract

The invention relates to an infusion apparatus with an automatic liquid changing function. The infusion apparatus with the automatic liquid changing function comprises a medicine bottle retainer and an infusion tube, wherein three branches are arranged on the upper side of the infusion tube; each branch can be connected with a corresponding dropping bottle; and an infusion tube portion of each branch is clamped by a clamp. In a working mode of the clamp, rotation of the clamps is controlled through clamp control units so that the clamps can be opened and closed. When infusion of the dropping bottle 1 is carried out, the clamp of the dropping bottle 1 is opened, but the clamp of the dropping bottle 2 and the clamp of the dropping bottle 3 are not opened; after medicine liquid in the dropping bottle 1 runs out, a liquid level sensor 1 monitors signals and transmits the signals to a central processing unit, then work of the clamps is controlled, the clamp of the dropping bottle 2 is opened, and simultaneously, the clamp of the dropping bottle 1 is closed; and after liquid in the dropping bottle 2 runs out, a liquid level sensor 2 monitors signals and transmits the signals to the central processing unit, work of the clamps is controlled, the clamp of the dropping bottle3 is opened, and simultaneously the clamp of the dropping bottle 2 is closed. Liquid changing complexity is avoided, infusion accuracy and infusion reliability are guaranteed, and the safety of venous infusion of a patient is improved.

Description

With the transfusion device certainly moving liquid
Technical background

Background technology
Transfusion device is very common medical apparatus and instruments, is mainly used in setting up the medicine liquid channel between the medical container such as infusion bottle or transfusion bag and vein.
Existing transfusion device in use, need whether to carry complete by manual observation medicinal liquid, to notify that nursing staff carries out changing dressings, pulling out the operations such as pin in time, if the sleeping non-Timeliness coverage medicinal liquid conveying of patient is complete in infusion process, fail to change dressings in time, be very easy to cause gas to enter the malpractice such as vein, blood backflow.
Summary of the invention
For the deficiency described in background technology, the present invention spy provide a kind of transfusion device certainly can moving liquid.
Can change dressings in time when medicinal liquid is carried complete avoid gas to enter the malpractice such as vein, blood backflow to realize transfusion device, technical scheme is as follows:
A kind of transfusion device with certainly moving liquid, comprise medicine bottle retainer, medicine bottle, automatically liquid changing device, clip, tube for transfusion, liquid level sensor 1, central processing unit 2, clip control unit 3 clip 4, liquid level sensor 1, central processing unit 2, clip control unit 3 are connected successively with clip 4, described liquid level sensor 1 is connected on medicine bottle, and described clip 4 is connected to tube for transfusion branch external.Described medicine bottle retainer has two bracing frames or two or more, and described tube for transfusion You Liangge branch or two or more, described branch is provided with the syringe needle being connected to medicine bottle.
The working method of described clip 4 controls the rotation of clip 4 to realize the keying of clip by clip control unit 3.When medicine bottle starts to infuse, the clip 4 of this tube for transfusion branch external is opened, and the clip 4 of other medicine bottle tube for transfusion branch external is not opened; After the water droplet of described medicine bottle is complete, liquid level sensor 1 on it monitors signal and reaches central processing unit 2, and then it is closed to control clip 4 work, and now another one liquid level sensor 1 is started working, monitor signal and reach central processing unit 2, the clip 4 connected thereon is opened.
Described medicine bottle retainer, comprise upper face, bracing frame and lower face three part composition, wherein bracing frame is between upper face and lower face, bracing frame plays the effect connecting upper face and lower face, there is an installing hole at bracing frame and lower face center, and the installing hole of bracing frame is identical with the installing hole diameter in the middle of lower face and coaxial.Upper face has the through hole of minimum two, the through hole on upper face is scarcely at the center of upper face, and the through hole on upper face is arranging for center of circle radius is greater than the circumferentially average of the diameter of the through hole on upper face with the center of upper face.Larger than the overall diameter diameter of the bottom body of medicine bottle one millimeter of the diameter of the through hole on upper face, lower face is except the through hole of centre, also has the through hole that axle center is identical with the number of openings on upper face, the axle center of the through hole on the axle center of the through hole on lower face and upper face on the same axis, the diameter of the through hole on lower face compared with medicine bottle bottleneck overall diameter greatly but be less than the overall diameter of medicine bottle body.During by the bottleneck end of medicine bottle successively through the through hole on upper face and the through hole on lower face, ensure the bottleneck of medicine bottle through at the bottom of the bottle of medicine bottle while the through hole on lower face also in the through hole of upper face.
Described clip 4 is dismountable clip 4, and also manually can go the open and close controlling clip 4.Prevent liquid level sensor 1 or clip 4 from having used of a specified duration insensitive, and cause erroneous judgement, dropping liquid mistake, affect patient health.
The invention has the beneficial effects as follows and can realize, from moving liquid, solving the complexity of changing liquid again and again, ensure accuracy, the reliability of transfusion, improve the safety of patient's venous transfusion.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
A kind of transfusion device with certainly moving liquid, comprise medicine bottle retainer, medicine bottle, automatically liquid changing device, clip, tube for transfusion, liquid level sensor 1, central processing unit 2, clip control unit 3 clip 4, liquid level sensor 1, central processing unit 2, clip control unit 3 are connected successively with clip 4, described liquid level sensor 1 is connected on medicine bottle, and described clip 4 is connected to tube for transfusion branch external.Described medicine bottle retainer has two bracing frames or two or more, and described tube for transfusion You Liangge branch or two or more, described branch is provided with the syringe needle being connected to medicine bottle.
The working method of described clip 4 controls the rotation of clip 4 to realize the keying of clip by clip control unit 3.When medicine bottle starts to infuse, the clip 4 of this tube for transfusion branch external is opened, and the clip 4 of other medicine bottle tube for transfusion branch external is not opened; After the water droplet of described medicine bottle is complete, liquid level sensor 1 on it monitors signal and reaches central processing unit 2, central processor 2 carries out process, the comparison of data, and then it is closed to control clip 4 work, now another one liquid level sensor 1 is started working, and monitors signal and reaches central processing unit 2, and central processor 2 carries out process, the comparison of data, and then control clip 4, connection clip 4 is thereon opened.
