Abstract
The utility model relates to a medical teaching device, in particular to a full-functional artificial intravenous transfusion arm which is used by medical staff or students to simulate the back of a real human hand and practice intravenous injection. A liquid storage capsule is arranged in a hollow plastic arm, the back of a plastic palm is provided with a hole, in which an artificial hand back skin is arranged, and an artificial venous network is arranged in the artificial hand back skin and connected with the liquid storage capsule through a tube. The utility model has the advantages of simple structure and low fabrication cost, and the standard actions of intravenous transfusion can be fully simulated and practiced.
Description
Technical field
The utility model relates to a kind of medical educational device, particularly practises intravenous teaching aid for medical worker or student's simulates real people the back of the hand.
Background technology
The present medical worker of China or to defend the school student all be to use true man's practical operation when the injection of exercise hand back vein, particularly defending the school student all practises the other side mutually on hand, this is brought very big misery by the injector, also makes operator's stress, and practice effect is had a greatly reduced quality.In order to address this problem, emulation venous transfusion arm has now appearred on the market, and its adopts medical latex to make, and directly emulation vein and vein is made on the arm, is contained in the box, and a liquid storage capsule is housed on the lid.When simulation transfusion exercise, open the lid, liquid storage capsule position raises, and pattern is intended the gravity of blood plasma with the emulation venous engorgement on the back of the hand, can carry out puncture procedure.This teaching aid only can only be done the venipuncture exercise, and have the following disadvantages: (1) manufacture difficulty is big, and cost is higher, and the market price of an emulation venous transfusion arm is on average at 1500 yuan～3000 yuan, and therefore puncture whole the arm in back several times is not used for practising with regard to subscription rate substantially; (2) it does not need to make and tightens the operation of tourniquet and tourniquet released, can not observe automatic blood back phenomenon in the vein blood vessel even if puncture needle penetrated, and more can not carry out drip-feed (transfusion) and practise.Therefore misfit with the standard operation of reality, be unfavorable for student's formal training; (3) degree true to nature of rete venosum is poor, because rete venosum and emulation arm are made of one, also just is not easy very meticulous on the mould process.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of global function emulation venous transfusion arm, and simple in structure, cost of manufacture is low, and the degree height true to nature of rete venosum is practised in the standard action in the time of can simulating venous transfusion fully.
Solving the scheme that technical matters of the present utility model adopts is: in the plastic cement arm of hollow the liquid storage capsule is housed, the back of the hand place of plastic cement palm has the hole, the simulation skin of dorsum of hand of packing in the hole has the emulation rete venosum in the simulation skin of dorsum of hand and links to each other with the liquid storage capsule by pipe.
The liquid storage capsule rear end of this global function emulation venous transfusion arm also is connected with a pipe, connects a fluid infusion (holding liquid) bag, and stop valve is housed on the pipe; The simulation skin of dorsum of hand is connected by pipe adapter with pipe between the liquid storage capsule, and stop valve is equipped with at the pipe adapter two ends.The simulation skin of dorsum of hand is formed by identical top photoplate of shape and following latex base plate bonding, is carved with the imitative vein groove that leads to the end pipe on the following latex substrate.
During use, by the venous transfusion operation steps of standard, tighten tourniquet on the simulation arm, the liquid storage capsule is subjected to the tourniquet compressing that the simulate blood pressure of interior storage is raise, and the emulation rete venosum on the simulation skin of dorsum of hand fills, and can carry out venipuncture procedure.When accurately penetrating, the automatic blood back of the visible simulate blood in syringe needle transparent tube place, blood is return in the blood vessel automatically when tourniquet released, can carry out the transfusion operation operation practice.Transfusion finishes when pulling out pin, still by standard operating procedure pinprick is sterilized, and at this moment can use glue simulation thimerosal, and pinprick is repaired to increase the service life.When the simulation skin of dorsum of hand damaged, stop valve that can blanked-off pipe joint two ends was pulled up the simulation skin of dorsum of hand from pipe adapter, and what more renew gets final product.During the transfusion exercise, open the stop valve that leads to fluid infusion (holding liquid) bag, just the pin water in the infusion bottle can be entered fluid infusion (holding liquid) bag by the pipe of liquid storage capsule rear end.Simulate blood in repeatable operation in the liquid storage capsule has loss, at this moment can replenish by its latter linked fluid infusion bag.
The beneficial effects of the utility model are: simple in structure, cost of manufacture is low, do not need emulation rete venosum and arm are manufactured one, therefore average unit cost only needs 200 yuan～300 yuan one, and after damaging, the puncture of simulation skin of dorsum of hand is easy to change, only about 5 yuan, vast student can both bear this expense to every cost, and has eliminated painful and nervous in the exercise; Fit like a glove with the operation of clinical venous transfusion, need make and tighten tourniquet (visible the back of the hand simulation vein blood vessel is full) and tourniquet released (the back of the hand simulation vein blood vessel restores to the original state), can practise the operation of whole venous transfusion process and the variable valve adjustment transfusion speed by transfusion device; The rete venosum of simulation skin of dorsum of hand adopts isolating construction bonding, and imitative vein groove and photoplate are just done very true to naturely easily, make the better effects if of exercise.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is simulation skin of dorsum of hand synoptic diagram.
Each label is represented successively among the figure: the back of the hand 1, simulation skin of dorsum of hand 2, stop valve 3, pipe adapter 4, pipe 5, liquid storage capsule 6, pipe 7, stop valve 8, simulation arm 9, fluid infusion bag 10, photoplate 2-1, imitative vein groove 2-2, latex substrate 2-3.
Embodiment
As Fig. 1, shown in Figure 2, simulate the liquid storage capsule 6 of having packed in the arm 9 at the plastic cement of hollow, its rear end is also by pipe 7, connect a fluid infusion (holding liquid) bag 10, stop valve 8 is housed on the pipe 7, the back of the hand 1 place of plastic cement palm has the hole, pack in the hole and simulate skin of dorsum of hand 2, simulation skin of dorsum of hand 2 is an isolating construction, be bonded by identical top photoplate 2-1 of shape and following latex substrate 2-3, latex substrate 2-3 goes up by the mold pressing processing mode and extrudes meticulous imitative vein groove 2-2, leads to pipe 5 and links to each other with liquid storage capsule 6, and pipe adapter 4 is arranged on the pipe 5, can easily the pipe 5 on the simulation skin of dorsum of hand 2 be connected with liquid storage capsule 6, on the pipe 5 at pipe adapter 4 two ends stop valve 3 is housed, closes stop valve 3, prevent that simulate blood from spilling when changing simulation skin of dorsum of hand 2.
