Abstract
The utility model relates to a blood vessel perfusion device, which comprises a syringe, a syringe needle and a connecting tube, wherein the connecting tube is used for connecting the syringe with the syringe needle. The syringe comprises a piston handle, a piston tube, a connecting head part connected with the connecting tube and a micro syringe pump, and the micro syringe pump comprises a syringe command receiver, a controller and an actuator for controlling the motion of the piston handle. The syringe command receiver controls the actuator through the controller. By adopting the technical scheme, the blood vessel perfusion device can greatly regulate the pressure and flow of injecta.
Description
Technical field
This utility model relates to field of medicaments, particularly a kind of vascular perfusion device.
Background technology
At present, perfusion for the organ blood vessel, research worker generally adopts syringe, connection tube, injection needle, connection tube is used to connect syringe, injection needle, syringe includes the piston handle, piston tube, the connection head that is connected with connection tube, piston handle by artificial pushing syringe, injection in the syringe flows into the transfusion operation of realizing in the injection needle patient's blood vessel through connection tube, the general injection needle that adopts is sharp scalp acupuncture head, this sharp scalp acupuncture head loses blood vessel easily, cause unnecessary damage, and manually promote the piston handle and can make that the injection pressure in the syringe is inhomogeneous, and then cause by the flow difference of the effusive injection of injection needle when the intravasation, may cause the damage of blood vessel.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, this utility model provides a kind of vascular perfusion device, can regulate pressure, the flow of injection well.
The technical solution of the utility model: a kind of vascular perfusion device, include syringe, injection needle, connection tube, described connection tube is used to connect syringe, injection needle, the connection head that described syringe includes piston handle, piston tube, is connected with connection tube, also include the injection Micropump, described injection Micropump includes injection order receptor, controller, is used for the executor of control piston handle motion, described injection order receptor via controller control executor.
Adopt technique scheme, utilize the injection Micropump that the piston handle of described syringe is controlled, in the time of can avoiding Artificial Control, the different phenomenon of injection pressure, flow that is produced, the injection Micropump can directly be bought on market, research worker preestablishes pressure, the flow value of needed injection earlier, receive the signal that sets by described injection order receptor, send controller to, by controller described executor is controlled again, last executor promotes described piston handle motion, realizes the perfusion to the organ blood vessel.
Further improvement of the utility model: described injection needle is blunt nosed syringe needle.
Adopt above-mentioned further improvement, adopt blunt nosed syringe needle can prevent when injection needle is inserted the organ blood vessel injured blood vessel.
Further improvement more of the present utility model: described injection Micropump also includes the clamping element that is used to clamp the syringe piston pipe.
Adopt and above-mentionedly further improve again, when patient is carried out intravascular injection, can utilize the injection Micropump that syringe is clamped, do not need research worker to arrest syringe, the further like this stability that has improved injection pressure, flow with hands.
Description of drawings
Fig. 1 is the structural representation of this utility model specific embodiment;
Fig. 2 is the theory diagram of this utility model specific embodiment.
The specific embodiment
As shown in Figure 1, 2, a kind of vascular perfusion device, include syringe 1, injection needle 2, connection tube 3, described connection tube 3 is used to connect syringe 1, injection needle 2, the connection head 13 that described syringe 1 includes piston handle 11, piston tube 12, is connected with connection tube 3, also include injection Micropump 4, described injection Micropump 4 includes injection order receptor, controller, is used for the executor of control piston handle motion, described injection order receptor via controller control executor.In this utility model specific embodiment, the executor of the injection Micropump that is adopted is for promoting seat 41, this promotes seat 41 and conflicts with piston handle 11, receive the injection instruction of research worker at described injection order receptor after, via controller drives and promotes seat 41 slippages, and then promotion piston handle motion 11 realizes patient's blood vessel is poured into.
In this utility model specific embodiment, described injection needle 2 is blunt nosed syringe needle, described injection Micropump 4 also includes the clamping element that is used to clamp syringe 1 piston tube 12, and clamping element is the buckle 42 that is arranged on the injection Micropump 4, realizes fixing syringe 1 through described buckle 42.
Operation principle of the present utility model: set suitable injection pressure, flow by research worker according to patient's situation earlier, utilize buckle 42 that syringe 1 is fixed on the injection Micropump 4, again injection needle 2 is inserted in the patient's blood vessel, after injection Micropump 4 starts, the signal that injection order receptor is set research worker passes to controller, after the controller computing, actuate actuators promptly promotes seat 41 slippages, because promoting seat 41 conflicts with piston handle 11, piston handle 11 moves in piston tube 12, in this process, the pressure of injection, stability of flow.
