Description

Dispensing method for oncology department

Technical Field

The invention relates to the technical field of medical dispensing equipment, in particular to a dispensing method for oncology.

Background

Intravenous administration is the most common route of administration in all levels of medical institutions due to direct administration, rapid onset of action, and complete absorption. The prior dispensing work of intravenous administration is one of the most important daily works of nurses, the prior dispensing (liquid) method needs to be completed by using an indirect carrier (such as a syringe),

it is worth noting that the syringe dispensing operation process is roughly as follows, firstly, air larger than the dispensing amount is sucked in the syringe, then the syringe needle is inserted into the medicine bottle and the air is injected, then the medicine bottle is turned over, at this time, the medicine liquid in the medicine bottle can be easily extracted according to the atmospheric pressure principle, then the medicine bottle is inclined to one side, the needle is separated from the medicine liquid in the medicine bottle, some extra air in the bottle is used for reducing pressure, then the situation of medicine liquid injection can not be caused by withdrawing the needle, then the syringe is pushed to enable the piston to return, namely, the medicine liquid is filled in the syringe tube, the medicine liquid in the syringe can be completely injected into the medicine dispensing bottle, if a plurality of groups of medicine liquid are required to be mixed and prepared.

The above dispensing method has the following disadvantages: repeated puncture, multi-step operation and complex process; the liquid medicine in the syringe remains, causing about 5% of medicine waste; a large amount of medical garbage which needs to be classified is generated, and therefore a dispensing method for oncology is provided.

s2: placing a silicone tube 14 between the roller 7 and the gland 10, rotating the grab handle 13 to drive the screw 12 to rotate, and matching with the guide rod 11 to enable the gland 10 to move towards the silicone tube 14 and clamp the silicone tube 14;

s3: insert first syringe needle 15 in the outside medicine bottle, insert outside medicine dispensing bottle with second syringe needle 16 in, starting motor 4 drives gyro wheel 7, roller 8 and rotates, makes the liquid medicine in the medicine bottle pump in the medicine dispensing bottle by silicone tube 14.

Through setting up infusion mechanism, place silicone tube 14 between gyro wheel 7 and gland 10, rotation grab handle 13 drives screw rod 12 and rotates, cooperation guide bar 11 makes gland 10 move and press from both sides tight silicone tube 14 to silicone tube 14, insert first syringe needle 15 again in medicine bottle 111, second syringe needle 16 inserts in medicine bottle 112, starter motor 4 drives gyro wheel 7, roller 8 rotates, the liquid medicine in medicine bottle 111 is pumped into medicine bottle 112 by silicone tube 14 in, gyro wheel 7 and gland 10 are like pressing from both sides a hose that is full of fluid with the finger, along with the inside fluid forward movement of the forward slip pipe of finger, through the elastic conveying hose extrusion of pump and release pump fluid in turn. Just like squeezing the hose with two fingers, as the fingers move, negative pressure is formed in the hose, and the liquid flows along with the negative pressure.

Meanwhile, in the operation process of the infusion mechanism, the rotating grab handle 13 drives the screw rod 12 to rotate and adjust the distance that the gland 10 presses the silicone tube 14 in consideration of convenience in adjusting the flow in the silicone tube 14, so that on the premise that the gland 10 clamps the silicone tube 14, the smaller the distance between the gland 10 and the roller 7 is, and the smaller the volume of the fluid is.

The dispensing device is used for dispensing instead of the traditional injector dispensing mode, one medicine bottle 111 only needs to be punctured once, only needs to be punctured once for dispensing, does not need to be punctured repeatedly, and is convenient to operate; the waste of the liquid medicine is reduced, and the generation of medical garbage is reduced.

A controller 17 is fixedly installed on the frame 3, the motor 4 is connected to the controller 17 through signals, and the controller 17 is used for controlling the motor 4 to work; the controller 17 is used for controlling the rotating speed and the rotating direction of the motor 4 and meeting the dispensing requirements under different conditions.

Example 2:

the actual working state of the first needle 15 inserted into the medicine bottle 111 and the second needle 16 inserted into the medicine dispensing bottle 112 can refer to fig. 10 and 11 in the attached drawings, when the needles are inserted into the stopper of the medicine dispensing bottle, the operation details are considered, if the needles are inclined, so that a gap exists between the needles and the stopper, at this time, the device can normally operate, but when the needles and the stopper are tightly attached and approximate to a sealing state, at this time, because the air pressure inside the medicine bottle 111 is gradually discharged along with the medicine liquid, the air pressure inside the medicine bottle 111 is reduced, so that the medicine liquid backflow phenomenon is generated after the motor 4 is stopped, and meanwhile, the air pressure inside the medicine dispensing bottle 112 is increased along with the increase of the medicine liquid, so that the silicone tube 14 near the mouth of the medicine dispensing bottle 112 is expanded or even blown out.

Referring to fig. 1-11, as another preferred embodiment of the present invention, the difference from embodiment 1 is that a non-return mechanism is disposed at the first needle 15, the non-return mechanism includes a first needle holder 18, the first needle holder 18 is fixedly connected to the end of the silicone tube 14, the top of the first needle 15 is fixedly connected to the first needle holder 18 and is communicated with the silicone tube 14, a third needle 19 is fixedly mounted at the bottom of the first needle holder 18, a first rigid tube 20 is fixedly mounted at the top of the first needle holder 18, and the first rigid tube 20 is communicated with the third needle 19;

in the S3, the step of driving the roller 7 and the roller 8 to rotate by the starting motor 4 to pump the liquid medicine in the medicine bottle into the medicine dispensing bottle by the silicone tube 14 further includes:

s31: the third needle 19 is inserted into the medicine bottle together with the first needle 15, and when the air pressure in the medicine bottle is reduced, the external air can enter the medicine bottle from the first hard tube 20 and balance the air pressure.

By providing the non-return mechanism, the third needle 19 is inserted into the medicine bottle 111 together with the first needle 15, and when the air pressure in the medicine bottle 111 is reduced, the external air can enter the medicine bottle 111 from the first rigid tube 20 and balance the air pressure.

When the medicine dispensing operation of the anti-tumor medicine is considered, medical staff directly contact dangerous (such as anti-tumor) medicines during the medicine dispensing operation, potential harm is brought to operators, meanwhile, liquid medicine molecules enter the air, the health of the medical staff is affected, the air environment of a medicine dispensing room is polluted, and on the other hand, liquid medicine is exposed in the outside air, contacts and exchanges with the outside air, and the liquid medicine is easily polluted.
