A kind of multichannel transfusion device
Technical field
The present invention relates to a kind of multichannel transfusion device.
Background technology
Transfusion device is the apparatus commonly used in the medical treatment, the employed transfusion device of present medical institutions is essentially the unipath transfusion device, and some medicine need be used and can not mix, for example when infusion aminoacid and fat milk, the infusion of fat milk needs more than 6 hours, preferably can cooperate the infusion better effects if with aminoacid, the unipath transfusion device can't be finished this task.When patient needs the infusion multiampule medicine, need nurse's real-time monitoring and repeatedly manually change liquid, both increased patient's misery and expense, increased the nurse job amount again.In addition, when needing liquid, the infusion routine also needs suitable slow medicine such as nitroglycerin of infusion instillation time, the unipath transfusion device can not guarantee two kinds of liquid infusion simultaneously, patient's state of an illness needs the micro-injection pump micro pump to go into medicine, is not the problem that the unipath transfusion device can solve as insulin, dopamine, sodium nitroprusside etc.Therefore, be badly in need of exploitation one cover multichannel transfusion device.
Summary of the invention
The objective of the invention is the deficiency at existing single channel transfusion device, a kind of multichannel transfusion device is provided.It is characterized in that this transfusion device only need be connected each path before transfusion with corresponding flow of infusate, the switch by control folder stream valve just can optionally carry out the transfusion of certain drug or drug regimen.
For achieving the above object, the present invention realizes by the following technical solutions: this transfusion device is made up of transfusion bag or infusion bottle joint (1), transfusion bypass duct (2), branch road flow regulator (3), branch road folder stream valve (4), multichannel interface (5), main tube for transfusion (6) and injection needle (7).
Transfusion bag provided by the present invention or infusion bottle joint, transfusion bypass duct, branch road flow regulator and branch road folder stream valve constitute a kind of injection canal of medicine, and the number of injection canal can be 1~100.
Folder stream valve provided by the present invention is the clip that places the tube for transfusion outside, is in the clamping closed condition at ordinary times, during use, opens and can guarantee that corresponding infusion channel is circulation status after folder flows valve.
Multichannel interface provided by the present invention is used for multiway infusion tube and to a tube for transfusion.For example, during with two passages and to a tube for transfusion, can adopt Y type interface.
When multichannel transfusion device provided by the present invention is used for the transfusion of multiple medicines thing, can simultaneously multiple drug channel be merged connection, folder stream valve patient easy to operate or medical personnel located either are changed the liquid operation, greatly increase work efficiency.
Description of drawings
Fig. 1. structural representation of the present invention.Among the figure: (1) transfusion bag or infusion bottle joint, (2) transfusion bypass duct, (3) branch road flow regulator, (4) branch road folder stream valve, (5) multichannel interface, (6) main tube for transfusion, (7) injection needle.
Specific embodiments
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
A kind of multichannel transfusion device comprises (1) transfusion bag or infusion bottle joint, (2) transfusion bypass duct, (3) branch road flow regulator, (4) branch road folder stream valve, (5) multichannel interface, (6) main tube for transfusion and (7) injection needle.Concrete operation method is as follows:
1, different branch road tube for transfusions is connected upward transfusion bag or infusion bottle by joint, the other end is connected with the multichannel interface;
2, the first end of main tube for transfusion and entry needle is connected in the multichannel interface, and other end syringe needle directly injects the patient;
3, open the folder stream valve of specific passageways, begin transfusion, when infusing for the multiple medicines thing, following two kinds of methods can be arranged: 1. order is opened each folder stream valve successively, realizes the order transfusion of different pharmaceutical; 2. open several folder stream valves simultaneously, realize that multiple medicine makes up transfusion simultaneously.
