Abstract
The invention discloses an airtight negative pressure type high-capacity blood circulation device for a vein model, belongs to medical teaching models, and particularly relates to a blood circulation dynamic device for a venous puncture teaching model. A closed plasma storage tank is connected with an inlet of an elastic work bag, an outlet of the elastic work bag is connected with a vein model vascular net, an outlet of the vein model vascular net is connected to the plasma storage tank through a plasma return pipe, a drain pipe is connected to one side of the return pipe, the outlet and inlet of the elastic work bag are each provided with a one-way valve, and a one-way damper valve is installed at the position where the vein model vascular net is connected with the plasma storage tank. The device is connected with a vein model at the corresponding position to form a high-simulation model with venous blood circulation, and practice similar to clinical venous infusion can be provided for practitioners.
Description
Technical field
The invention belongs to medical educational model, be specifically related to the teaching mode blood circulation driving device of a kind of venipuncture.
Background technology
Current venipuncture teaching much uses animal, and its instruction cost is high, and usual student is difficult to obtain the chance starting to practise.In order to solve this problem, Chinese patent literature discloses the paracentesis model such as some simulation training arms, simulation palm, the structure great majority of these training patterns are, configuration simulation vein under silica gel skin, simulation vein model connects a plug-in blood plasma capsule, the height blood plasma blood vessel filling function under gravity hung by blood plasma capsule.Principle simple simulation degree is relatively low, it is impossible to matches with clinical practice operation, it is impossible to complete the exercise of whole infusion process, has significant limitation on using.
Summary of the invention
The technical problem to be solved is to provide a kind of airtight negative-pressure type Large Copacity vein model blood circulation device, can be connected with all kinds of vein model, form a high phantom having venous blood circulation, simulation blood flow volume is many, simulating medicinal liquid in infusion process can be with blood automatic shunt, it is possible to provide the operation practice matched with clinical vein transfusion to practitioner.
Realize above-mentioned purpose of the present invention to be adopted the technical scheme that: the blood plasma storage tank of closing connects the entrance of elastic working capsule, the outlet of elastic working capsule connects vein model vasoganglion, the outlet of vein model vasoganglion is connected to blood plasma storage tank by blood plasma return duct, return duct is also other is connected to a discharging tube, it is respectively provided with a check valve in the entry and exit of elastic working capsule, connects at blood plasma storage tank equipped with an one-way damper valve at vein model vasoganglion.
Elastic working capsule is spherical hollow capsules, and each check valve uses valve check valve.
The entrance of elastic working capsule accesses blood plasma storage tank bottom by pipette, and the outlet of vein model vasoganglion accesses blood plasma storage tank top by return duct, is connected on this return duct by discharging tube at blood plasma storage tank.
Beneficial effect: being connected with elastic working capsule owing to have employed the blood plasma storage tank of closing in the present invention, and be provided with check valve in place, therefore blood plasma storage tank makes simulation blood flow volume be greatly increased；Elastic working capsule is conducive to being connected with each position venipuncture model, and is provided that enough pressure makes the venous engorgement degree of site of puncture preferable；Each check valve and the setting of discharging tube, it is ensured that simulation medicinal liquid can shunt with blood automatic liquid, is therefore used for multiple times or accesses more than one piece venipuncture model and also will not water down blood plasma when transfusion training.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: return duct 1, vein model vasoganglion 2, check valve 3, elastic working capsule 4, check valve 5, orifice valve 6, discharging tube 7, blood plasma storage tank 8, pipette 9, outlet tube 10.
Detailed description of the invention
The structure of the present invention is further described below in conjunction with Figure of description.
Seeing accompanying drawing, this device comprises 3 parts, vein model vasoganglion 2(elastic rubber tube), elastic working capsule 4(is made up of the rubber of good springiness) and blood plasma storage tank 8(rigid plastics make).The entry and exit of elastic working capsule 4 are equipped with check valve 5,3.When only pressurizeing elastic working capsule 4, intracapsular pressure increases, and check valve 3, orifice valve 6 are opened, and check valve 5 is closed, and simulating blood plasma flows into venous blood pipe network 2 by outlet tube 10, then flows into blood plasma storage tank 8 by return duct 1.When releasing the pressure to elastic working capsule 4, in elastic working capsule 4, negative pressure increases, and simulating blood plasma is flowed into elastic working capsule 4 by blood plasma storage tank 8 and forms the circulation of venous blood.As pressurizeed elastic working capsule 4 and return duct 1 simultaneously, intraluminal pressure increases backflow obstruction simultaneously, and check valve 3 is opened, check valve 5 is closed, in capsule, the simulating blood plasma of storage is filled with vein model vasoganglion 2, and venous blood pipe network is full and pressure increases, if venous blood pipe network is punctured just visible blood-flow.When releasing elastic working capsule 4 and the pressure of return duct 1, the negative pressure in elastic working capsule 4 increases, and check valve 3 is automatically switched off, and one-way valve 5 automatically turns on.Under suction function, in blood plasma storage tank 8, blood plasma flows into elastic working capsule 4, under suction function, in return duct 1, blood plasma flows into blood plasma storage tank 8.When elastic working capsule 4 is in static transition, to vein model defeated simulation medicinal liquid, owing to discharging tube 7 is in Full-open state, return duct 1 is provided with one-way damper valve 6 and forms certain resistance, defeated liquid only can to open unresisted discharging tube 7 direction flowing, may not flow into venous plasma storage tank 8, it is achieved that simulation medicinal liquid and the purpose of blood automatic shunt.This device can form automatic blood circulation height emulation vein model with the linking of any vein model, and vein model plasma volume can determine according to venous plasma storage tank size.
