Description
Technical Field
The utility model relates to the field of medical equipment, especially, relate to an automatic open transfusion system who stops.
Background
The infusion apparatus that current clinical was using is in the use, if the upper limbs at the infusion side measure the periphery and have a non-invasive blood pressure, will have blood backflow to enter the infusion pipeline, leads to the liquid level of infusion apparatus buret to constantly rise, and the unable normal instillation that resumes of infusion apparatus after the pressure measurement is finished needs the nurse in time to handle. If the blood is not treated in time, the blood in the infusion pipeline may be coagulated, the infusion apparatus needs to be replaced, and the venous thrombosis in the body of a patient can be caused in serious cases.
The utility model aims at providing an automatic transfusion system who stops is opened to solve the phenomenon of measuring the blood reflux in the infusion pipeline when the periphery does not have the wound blood pressure, and when the pressure measurement ended, liquid can the automatic recovery instillation in the transfusion system.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an automatic open transfusion system who stops to the not enough of prior art, return blood in the infusion pipeline when can preventing to measure blood pressure.
The purpose of the utility model is realized through the following technical scheme: an infusion apparatus with automatic start and stop comprises a burette, an upper infusion catheter and a lower infusion catheter which extend into the burette, and an automatic start and stop device on an infusion hose;
the automatic start-stop device is positioned below the burette, is a part of the lower infusion catheter, and comprises a hexagonal hard tube body for liquid medicine to pass through and a cone positioned in the hexagonal hard tube body, the tip of the cone faces the burette, two sides of the bottom of the cone are respectively provided with a first small ring, the inner wall of the hexagonal hard tube body is respectively provided with a second small ring at the position vertically opposite to the first small ring, and the vertically opposite first small ring and the second small ring are connected through a spring;
and limiting rods are respectively arranged on two sides of the lower end of the cone, the distance between each limiting rod and the top end of the hexagonal hard tube body is smaller than the height of the cone, and meanwhile, the tip of the cone extends out of the hexagonal hard tube body and is provided with a gap for the medicine liquid to pass through with the inner wall of the lower infusion catheter.
Further, the density of the cone is greater than the liquid in the infusion pipeline, and the diameter of the cone is greater than the inner diameter of the lower infusion conduit.
The utility model has the advantages that: the utility model provides an automatic open transfusion system who stops for the phenomenon of blood reflux in the infusion pipeline when solving and measuring the periphery and not having the wound blood pressure, and when the pressure measurement ended, liquid can the automatic recovery instillation in the transfusion system. Compared with the existing infusion apparatus, the infusion apparatus can not only reduce the workload of medical personnel, but also avoid venous thrombosis or air embolism of patients caused by infusion.
Drawings
Fig. 1 is a structural schematic diagram of an infusion apparatus with automatic start and stop.
Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
As shown in figure 1, the utility model provides an automatic transfusion system who opens and stop specifically is a venous transfusion system of blood return in the infusion pipeline when can preventing to measure blood pressure, and the transfusion system can normal infusion of automatic recovery when the pressure measurement finishes moreover, does not need the manual processing. The automatic start-stop device is positioned below the burette 1, is a part of the lower infusion catheter 3, and comprises a hexagonal hard tube body 401 for passing liquid medicine and a cone 402 positioned in the hexagonal hard tube body, wherein the density of the cone 402 is greater than the liquid in the infusion tube, the diameter of the cone 402 is greater than the inner diameter of the lower infusion catheter 3, the tip of the cone 402 faces the burette 1, two sides of the bottom of the cone 402 are respectively provided with a first small ring 405, the inner wall of the hexagonal hard tube body 401 is vertically opposite to the first small ring 405 and is respectively provided with a second small ring 406, and the vertically opposite first small ring 405 and the second small ring 406 are connected through a spring 403; the cone 402 is stabilized within the hexagonal rigid tube 401 without measuring blood pressure and without affecting the passage of fluid.
The two sides of the lower end of the cone 402 are respectively provided with a limiting rod 404, the height from the limiting rod 404 to the top end of the hexagonal hard tube body 401 is less than the height of the cone 402, meanwhile, the tip of the cone 402 extends out of the hexagonal hard tube body 401, and a gap for the liquid medicine to pass through is arranged between the tip of the cone 402 and the inner wall of the lower infusion catheter 3. Under the action of the stop lever 404, the cone 402 will not turn inside the hexagonal rigid pipe body 401.
When the blood pressure is measured from the transfusion side and the blood in the pipeline flows back, the cone 402 is rebounded upwards by the blood backflow pressure to seal the liquid inlet of the transfusion catheter 3 at the lower part of the burette, and the transfusion channel is closed at the moment, so that the blood is prevented from continuously flowing back upwards. The spring 403 normally causes the cone 402 to have some resilience to upward movement so that the returning blood under less pressure swings the cone 402 upward to close the infusion path. After peripheral non-invasive blood pressure measurement is finished, pressure in the infusion pipeline disappears, the cone 402 begins to sink due to the fact that the density of the cone 402 is larger than that of liquid, when the gravity of the cone 402, the pulling force of the spring 403 and the resistance of the liquid reach balance, the cone 402 stops at the initial position, at the moment, an infusion passage is opened, and the liquid in the pipeline is normally instilled.
The above-mentioned embodiments are provided for explaining the present invention, not for limiting the present invention, and any modifications and changes made to the present invention are within the spirit of the present invention and the scope of the claims and fall within the scope of the present invention.
