Abstract
The utility model relates to a teaching tool, particularly to a highly-simulated module which is used for medical care students to practice venipuncture skills. A simulated venous network made of elastic rubber is fixed on a base layer of the module, simulated skin made of elastic rubber is fixed on the surfaces of both the base layer of the module and the simulated venous network, the inlet end and outlet end of the simulated venous network are both connected with an elastic liquid storage vessel through hoses, and red-color disclosing solution is filled inside the liquid storage vessel. Thehighly-simulating venipuncture practice module with simple structure and low cost is more similar to the actual veins of a human body and is more helpful for students to rapidly master venipuncture skills.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of senior emulation module of medical care type student exercise venipuncture technical ability.
Background technology
Venipuncture is the workmanship that each medical care type student must be on top of, but skillfully always make us not too satisfied again what the actual teaching middle school student grasped, its main cause is that the fidelity of existing venipuncture exercise teaching aid is poor, and price is very high, and school and student are difficult to bear its high expense.The exercise module that has emulation latex skin to be prepared in the existing teaching aid, though can experience the subcutaneous vein of similar true man, the blood back state when exercise the time can not be reproduced actual puncture, so the student can not really realize the correct feel that punctures successfully.In the existing high-grade puncture exercise arm electronic pointer is housed, can demonstrate the success of whether puncturing, but its cost is higher, electronic devices and components damage easily, and out of the question emulation can only be simulation, differs greatly with clinical practice.In order to obtain real venipuncture experience, the student who has has to own or the classmate practises on health mutually, and this causes suffering for student's health or injure.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of high emulation venipuncture exercise module, and simple in structure, cost is low, and is more similar to real human vein, more helps the technical ability that the student grasps venipuncture fast.
Solving the scheme that technical matters of the present utility model adopts is: be fixed with the emulation rete venosum that elastic caoutchouc is made in module basic unit, surface at module basic unit and emulation rete venosum is fixed with the simulation skin that elastic caoutchouc is made, the two ends that go out, go into of emulation rete venosum connect elastomeric hydraulic accumulator by flexible pipe, the red display of packing in hydraulic accumulator liquid.
The technical solution of the utility model also comprises: the one side of described module basic unit is processed with the groove of depth dimensions less than emulation rete venosum caliber size, the emulation rete venosum is bonded in the groove, hydraulic accumulator is bonded in the another side corresponding grooves of module basic unit, the hydraulic accumulator two ends on pipe, be connected with the retaining valve valve respectively, the surface of module basic unit and emulation rete venosum is tightened and sticked on to simulation skin.
In addition.Before the inlet end retaining valve valve of hydraulic accumulator, be equipped with on the flexible pipe by card, and at the also other fluid infusion mouth that is connected to of the inlet end of hydraulic accumulator, the air in the emptying emulation rete venosum easily, and make and wherein be full of red display liquid.
The structure of described retaining valve valve is the rigid plastic tube chamber, the mouth of pipe sealing singly open to shell fragment, when having only the certain pressure of existence, shell fragment is just understood folk prescription to opening; Hydraulic accumulator can adopt is with flexible nonrigid plastic to make, and only needs gentle pressure just red display liquid can be charged in the emulation rete venosum during use.
The beneficial effects of the utility model are: adopt the mode that connects hydraulic accumulator in module basic unit, thereby make this exercise module have high emulation more, almost similar to real human body, help the student and grasp skill of venipuncture as soon as possible, and exempted the student on one's body in the misery of practising certainly; This apparatus structure is simple, and low cost of manufacture is cheap, can reduce school and student's expense greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Each label is represented successively among the figure: by card 1, fluid infusion mouth 2, go out end 3, retaining valve valve 4, hydraulic accumulator 5, simulation skin 6, retaining valve valve 7, flexible pipe 8, emulation rete venosum 9, go into end 10, module basic unit 11.
Embodiment
Referring to Fig. 1, be processed with and the identical groove of emulation rete venosum 9 shapes at module basic unit 11 upper surfaces, emulation rete venosum 9 is fixed with the emulation rete venosum 9 that elastic caoutchouc makes and is bonded in the groove; 11 lower surfaces also are processed with groove in module basic unit, and hydraulic accumulator 5, retaining valve valve 4 and 7 correspondences are bonded in the lower recess; Paste the simulation skin of tightening 6 again on the surface of module basic unit 11 and emulation rete venosum 9.Emulation rete venosum 9 and simulation skin 6 all adopt elastic emulsion to make, thereby have the effect true to nature with real skin, simultaneously the emulation rete venosum 9 self-enclosed performance identical with true man's vein.Going out end 3 and going into end 10 of emulation rete venosum 9 is connected in elastic hydraulic accumulator 5 by flexible pipe 8, fills red display liquid in the hydraulic accumulator 5.Inlet end at hydraulic accumulator 5 connects retaining valve valve 4, connect another retaining valve valve 7 at endpiece, be equipped with on the flexible pipe 8 before the retaining valve valve 4 of hydraulic accumulator by card 1 and the also other fluid infusion mouth 2 that is connected to, when extruding hydraulic accumulator 5, retaining valve valve 4 is closed, and retaining valve valve 7 is then opened, easily the air in the emptying emulation rete venosum 9, and make red display liquid full in emulation rete venosum 9, when showing that liquid is lossy, redness also can replenish by fluid infusion mouth 2 usefulness syringes.Retaining valve valve 4 and 7 adopts the rigid plastic tube chambers, the mouth of pipe be equipped with singly open to shell fragment, when not having pressure, always be in closed state.Red display liquid can enter emulation rete venosum 9 in the hydraulic accumulator 5 in order to make, and its material adopts is with flexible nonrigid plastic.
Running program is: 1. extract 20 milliliters of red simulation blood plasma with 50 milliliters of syringes earlier; 2. again by the fluid infusion mouth with vacuum pumping in the whole pipe network of emulation rete venosum, will simulate blood plasma then and inject in the emulation rete venosum, adopt the end that goes out by card sealing emulation rete venosum; 3. gently press back and forth several times and hydraulic accumulator, this moment simulate blood plasma and just can in the emulation rete venosum, fill; 4. puncture exercise: gently press hydraulic accumulator, simulation blood plasma is injected by the end of going into of emulation rete venosum, and the end that goes out of emulation rete venosum is cut off card and closes (unidirectional circulation is obstructed), emulation rete venosum internal pressure increases, and makes simulation skin protruding realistically.Be needled into the just visible blood back automatically of emulation rete venosum with venipuncture.Strengthen puncture exercise difficulty as need, that can unclamp the emulation rete venosum reduces simulation vein retraction by card (open unidirectional circulation path) simulation rete venosum internal pressure, and venipuncture difficulty strengthens.
