Abstract

The utility model relates to a sterilizing and magnetizing self-control infusion device, which is a power mechanism, quantitatively controlling transfusion speed, and is composed of an electromagnetic temperature controller and a transfusion mechanism which uses a sealed and compressed medicine bottle as a core. The utility model overcomes many defects of the existing transfusion device, can ensure that medical liquid can be transfused into a human body under the condition of sterility, and can reach constancy and uniformity of speed. The medical liquid with the equal temperature with the human body especially can eliminate pain, numbness and tumefaction of patients. Magnetized medical liquid can multiple to enhance phermacological efficiency.

Description

Sterilizing and magnetizing self-control infusion device

This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of injecting apparatus that makes medicinal liquid reach aseptic magnetization and can control transfusion speed automatically.

Human transfusion is the most frequently used a kind of medical measure of hospital.Existing infusion method is that the vial that will medicinal liquid be housed hangs on the drip stand, end with drainage tube inserts in the bottle again, for eliminating suction function, insert an air inlet pipe at bottleneck simultaneously, transfusion speed is observed with the tightness that clamps drainage tube by people's vision and is adjusted.Obviously there is following shortcoming in this infusion method: the one, and transfusion speed lacks scientific quantitative control, influenced by various factors to cause sometimes fast and sometimes slow, causes the human body discomfort; The 2nd, medicinal liquid communicates with extraneous air by air inlet pipe, makes the various pathogenic bacterias in the treatment environment enter medicine bottle by air inlet pipe, together imports human body with medicinal liquid again, causes cross infection, even can cause multiple complications, and medical effect is descended; The 3rd, fluid temperature is general to differ bigger with patient temperature, and particularly low temperature medicinal liquid input people knows from experience and causes local human body or vasoconstriction immediately, makes human body produce numbness, the sensation of pain, swelling.Japan has invented a kind of transfusion device at present, with the principle of reciprocating motion of the pistons transfusion speed is controlled, but also can't be got rid of above-mentioned back two kinds of shortcomings.

The purpose of this utility model designs a kind of novel infusion apparatus exactly, and it not only can control transfusion speed automatically, and guarantees that medicinal liquid can import in the sealed, sterile environment in patient's body, in addition, passes through the magnetized medicinal liquid of heating and can also reach aseptic synergic function.

Technical solution of the present utility model is:

A micromachine 10 is housed on the stake body 12 of this device, this motor can be done two-way rotation by a reversing switch control, this motor connects a driving gear 11, what be meshed with driving gear 11 is two driven gears 8 and 17 that are connected on pressure screw bolt 9 and 16, two pressure screw bolts 9 and 16 are positioned at stake body 12 upper/lower terminals, under the drive of micromachine 10, two pressure screw bolts 9 and 16 can be done the both forward and reverse directions rotation.There is a upper press cover 14 to be inserted in two pressure screw bolts 9 and 16 and be fixed on the stake body 12 of both sides on this device top, there is a lower cover 7 to be connected with 16 with two pressure screw bolts 9 with screw thread in the bottom, along with the positive and negative rotation of pressure screw bolt 9 and 16, lower cover 7 can pump.Compression medicine bottle 6 is rotated between upper press cover 14 and the lower cover 7, on upper press cover 14 tops an electromagnetism thermostat 3 is housed, it is made up of one group of coil and thermal relay, just form an electromagnetic field after the energising around, and can make by the medicinal liquid in the drainage tube 2 therebetween and heat and keep temperature constant state.

But in compression medicine bottle 6 upper end shot molding thicker needle holder 5, so that in bottle, add other medicament or insert that compression medicine bottle 6 can keep good sealing effectiveness when inhaling medicine syringe needle 13.

Can be warmed near human body temperature for guaranteeing to make, can make drainage tube 2 by electromagnetism thermostat 3 parts thick 2～4 times than other parts by the medicinal liquid in the drainage tube 2.Heat effect to slow down the medicinal liquid flow velocity, to reach.

But needle shield 15 of suit on the syringe needle 1 of drainage tube 2 is to guarantee being in the sealed, sterile state before drainage tube 2 uses.

Micromachine 10 can change voltage by a transformer plugs supply power, can change motor speed, to reach the purpose of control transfusion speed.At power input a motor commutation switch can be installed.

Accompanying drawing is the structural representation of an embodiment of this utility model.

Below in conjunction with accompanying drawing this utility model is further described:

Before the transfusion, the compression medicine bottle 6 that will fill medicinal liquid earlier is positioned between the upper and lower gland 14,7, and drainage tube 2 is passed the coil of electromagnetism thermostat 3, and the thicker part position is in the middle of coil and fixing.Take off the needle shield of inhaling on the medicine head 13, will inhale medicine syringe needle 13 and insert needle holder 5 by syringe needle hole 4.Use the transformer plugs energized, adjust suitable rotating speed, open electromagnetism thermostat 3 switches and motor commutation switch simultaneously, along with being rotated in the forward of micromachine 10, rotate by gear driven pressure screw bolt 9 and 16, lower cover 7 moves up afterburning in compression medicine bottle 6, and the bottle herb liquid just enters drainage tube 2 through inhaling medicine syringe needle 13, is magnetized in electromagnetism thermostat 3 and is warmed near human body temperature.Take off the needle shield 15 on the injection needle 1 this moment, and syringe needle is inserted human body, the injection beginning.When lower cover moves on to hole point, change the reversing switch position, make micromachine 10 backward rotation, lower cover 7 moves down, and extracts out and inhales medicine syringe needle 13, takes out compression medicine bottle 6, and transfusion finishes.

The utility model is compared existing infusion set, has significantly reached not to be subjected to human blood-pressure height difference and soup more or less that factors affect, and makes transfusion speed quantitative, and evenly, the infusion set of sealing has eliminated that germs have invaded the human body and cause the possibility of cross-infection; The soup of heating and temperature control has not only been got rid of the pain of human body, and has strengthened pharmacology usefulness through magnetized soup, and the real regeneration product that belongs to present transfusion instrument is promoted the use of and will be produced great social benefit.
