Description

Freely movable intravenous and intraarterial two-purpose infusion device

This utility model relates to a kind of medical apparatus and instruments that supplies clinical transfusion to use, particularly a kind of dual-purpose transfusion device of formula arteriovenous that moves freely.

Employed transfusion device can only be used for vein in the hospital at present, can not be used for tremulous pulse, thereby can not satisfy growing clinically needs at present, in particular for the arterial perfusion chemotherapy of treatment malignant tumor; In addition, the patient is liied in bed, keep certain position, can not walk about; And transfusion all will be done vascular puncture at every turn, increases a lot of miseries to patient.

The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of arteriovenous dual-purpose transfusion device; In infusion process, the patient can freely walk about; For the long-term patient who needs transfusion,, alleviated patient's misery greatly as long as a vascular puncture just can repeatedly be infused.

The purpose of this utility model is achieved through the following technical solutions.

Dual-purpose transfusion device mainly is made up of box body 1, liquid-accumulating bag 18, pressure apparatus, tube for transfusion 7, three-way valve 8, thin tube for transfusion 9, syringe needle 13, pinhead sleeve 12, effusion meter and alarm.Box body is a cuboid, and it is divided into loam cake 2 and bottom 3 two parts, makes with timber or other harder material; Liquid-accumulating bag places in the bottom, and pressure apparatus is satisfied with in the loam cake, and Pressure gauge 4 and the liquid alarm of being totally lost also is housed on this device; Liquid-accumulating bag is to make with the material of transparent flexible, its heap(ed) capacity is 500 milliliters, minimum capacity is 50 milliliters, one end of bag has two mouths of pipe: a mouth of pipe 19 is with piston 20, as the usefulness of adding medicine, another mouth of pipe 21 is connected with an end of tube for transfusion by effusion meter 5, the other end of tube for transfusion is connected to a three-way valve, valve is connected successively with thin tube for transfusion, syringe needle, be wrapped with wing sheet 10 on the syringe needle, and be with pinhead sleeve 12, it is the pinhead sleeve reinforcement that pinhead sleeve one end has a casing seat 11(), also be equipped with the leakage alarm herein, to guarantee the safety of transfusion.

During use, earlier transfusion is injected liquid-accumulating bag, it is placed in the bottom, starting pressure device compressing liquid-accumulating bag drives in liquid in the bag in the tube for transfusion, flows to blood vessel.Liquid in liquid-accumulating bag is totally lost, and is installed in negative plate 6 and the loam cake at the bottom of the box that positive plate 25 contacts on the pressure plare, and display lamp 17 is bright warning, so that in time change liquid-accumulating bag.The leakage alarm is made of battery 22, display lamp 17, hard sheet 39 and thin film 38, and battery plus-negative plate is connected on respectively on hard sheet and the thin film; In infusion process, if syringe needle is deviate from blood vessel, liquid leaks when subcutaneous, and cutaneous protuberance is pressed to hard sheet 39 with thin film 38 and directly contacted both positive and negative polarity connection this moment, the bright warning of display lamp herein.

For preventing that liquid from leaking in subcutaneous, as shown in Figure 9, can in infusion pipeline, connect a syringe 34 on the three-way valve 8, thin tube for transfusion 9 connects a joint 35.(see figure 10) places the B position with three-way valve handle 36 earlier during use, and this moment, syringe communicated with liquid-accumulating bag, in partially liq suction syringe; Handle is placed the D position, this moment, syringe communicated with syringe needle again; Hand-held wing sheet 10 carries out vascular puncture, during with the syringe pumpback blood back is arranged, and illustrates that puncture is normal, and the liquid in the syringe is advanced in the blood vessel, again handle 36 is placed the A position, and liquid-accumulating bag directly communicates with blood vessel, can infuse.In infusion process, suspend, handle can be placed the E position, cut off path and get final product as needing.

Pressure apparatus of the present utility model is divided into three kinds of different structures.

Embodiment 1:

As shown in Figure 3: pressure apparatus is the gas pressure formula.It is made of pressure bag 24, pressure plare 23, Pressure gauge 4 and the ball 14 of inflating.Pressure bag is made by rubber or plastic or other material, and is bigger slightly than liquid-accumulating bag, and pressure bag has two mouths of pipe, is equipped with Pressure gauge on the mouth of pipe, another by joint with inflate ball and be connected, on the pipeline that connects, control valve 16 is housed; The ball of inflating is made with rubber, and its upper and lower side respectively is equipped with check valve 15; Pressure plare adopts wooden or other hard material, is fixed in the loam cake with support 40.

During use, inflate ball with hands extruding, by check valve air is pressed in the pressure bag, make its expansion, pressure plare is pushed ahead, the extruding liquid-accumulating bag drives in liquid in the bag in the tube for transfusion, flows to blood vessel.

Embodiment 2:

As shown in Figure 4: pressure apparatus is the frame for movement formula.Mainly form by pressure arm, spring and pressure plare.Adorn a pressure arm 26 at last exterior surface, an end of arm puts in the lid and is connected with pressure plare 23, the other end of arm be fixed on the spring 27 that covers and be connected.

During use, the tension force by spring acts on pressure arm, and pressure plare is pushed ahead, and the extruding liquid-accumulating bag makes that liquid drives in the liquid-transport pipe-line in the bag.

Embodiment 3:

As shown in Figure 6: pressure apparatus is DYN dynamic.It mainly comprises the gear 41 on battery 22, motor 28 and the output shaft thereof, and it cooperates with slip teeth groove 29, and an end of teeth groove is connected with pressure roller 30, and pressure roller is installed on the roller bearing frame 31.Connect battery, motor rotates, and the gear driven slip teeth groove on its output shaft makes pressure roller roll along the roller bearing frame and pushes ahead, and pushes the liquid-accumulating bag below it simultaneously, to reach the purpose of transfusion.

Effusion meter of the present utility model can adopt two kinds of different structures.The pointer that rotation by motor drives effusion meter rotates, and is called the electrodynamic type effusion meter.Another kind of effusion meter is that it places the turbine 37 of tube for transfusion to be connected with one, when liquid flows in tube for transfusion, and the impulse turbine rotation, the pointer that turbine drives effusion meter rotates, and shows flow.This kind is called turbine meter.(seeing Figure 11)

Transfusion is in the pulse type input blood vessel, and it is achieved through the following technical solutions.

As shown in Figure 7: this device includes battery 22, the gear 41 on motor and the output shaft thereof, and there is a pressure arm 33 their lower end, and gearing is in the long end of pressure arm, and the short end of arm is connected with a spring.After motor was connected battery, driven gear 41 rotated, and the long end that it acts on pressure arm moves down, and the galianconism that is pressed in the arm on the liquid-accumulating bag outlet is lifted, in the bag liquid be able to by.When the long end of pressure arm was between two gears, spring 27 retracted galianconism again, is pressed on the outlet of liquid-accumulating bag, and liquid flow is obstructed.Carry out so repeatedly, liquid promptly is in the pulse type input blood vessel.This shows that the size of fluid flow can be adjusted the motor revolution.

Be totally lost behind the liquid at every turn, in pinhead sleeve, inject an amount of anticoagulant, needle sleeve is put stayed in blood vessel,, significantly reduced patient's burden and misery so that transfusion need not remake vascular puncture once more by three-way valve 3.
