Description

Internal medicine is with device of dosing

Technical Field

The utility model belongs to the technical field of the device of dosing, a medicine feeding device for internal medicine is specifically disclosed.

Background

The internal medicine plays an extremely important part in clinical medicine, and is not only the basis of clinical medicine but also has close connection with the clinical medicine. The knowledge of internal science comes from medical practice, and doctors in the past can remove false and true, remove coarse and collect semen through continuous accumulated experience in the process of treating diseases and saving people, the understanding level is continuously improved from practice, and a systematic disease diagnosis and treatment method is gradually formed through long-term accumulation for many years.

When a human body has internal diseases, the patient needs to go to a corresponding department of a hospital to diagnose and treat the diseases; after diagnosis and treatment by a doctor, the doctor usually prescribes a prescription for a patient and prepares a medicament, and the prepared medicament is usually in a tablet shape, a liquid shape or a powder shape. When a patient takes a liquid medicament, a quantitative amount of the liquid is required. In the prior art, liquid medicine is measured and taken by using a bottle cap generally, and after the liquid is poured out of the bottle cap, the liquid is left in the bottle cap, so that the dosage of the medicine is reduced, and the recovery of a patient is affected; when a patient takes the medicine with the bottle cap, the lips and the bottle cap can be in contact with each other to cause pollution, and the medicine is easy to deteriorate.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an internal medicine is with device of dosing to it uses bottle lid volume to get the problem that causes the medicine rotten easily to solve among the prior art to take liquid medicament.

In order to achieve the above object, the basic scheme of the utility model is: the drug delivery device for the internal medicine comprises a transparent barrel, wherein a feed inlet is formed in one side of the lower part of the barrel, a discharge outlet is formed in the other side of the lower part of the barrel, a first one-way valve which is opened in one way towards the inside of the barrel is arranged in the feed inlet, a second one-way valve which is opened in one way towards the outside of the barrel is arranged in the discharge outlet, a feed pipe is connected to the feed inlet, and a discharge pipe; barrel upper portion is equipped with the blind plate, and blind plate axis department is equipped with the through-hole, is equipped with vertical sliding seal connected's piston head in the barrel, and piston head upper portion is connected with vertical push rod, push rod and through-hole inner wall sliding connection, and the push rod is equipped with the recess of equipartition along vertical direction, and the upper portion horizontal sliding connection of blind plate has the gleitbretter with the recess adaptation, and the barrel is equipped with the scale along vertical direction.

The working principle of the basic scheme is as follows: before the device is used, the liquid inlet pipe is placed into the medicament bottle, the push rod is pulled upwards, the first one-way valve is opened when the push rod moves upwards, the second one-way valve is closed, and the piston head is connected with the inner wall of the barrel in a sliding and sealing manner, so that when the push rod and the piston head move upwards, the barrel is positioned below the piston head and is in negative pressure, medicaments in the medicament bottle are sucked into the barrel, when the medicament in the barrel reaches a specified scale, the slide sheet is pushed into the groove, and the discharge pipe is placed into a water cup or other cup bodies needing to use the medicaments; and then the sliding sheet is moved out of the groove, the push rod is pushed downwards, and the push rod moves downwards to discharge the medicament in the barrel body into a water cup or other cup bodies.

The beneficial effect of this basic scheme lies in:

(1) the device can accurately measure the amount of liquid medicament, can suck liquid medicament through the liquid inlet pipe and discharge the liquid medicament through the liquid discharge pipe, and does not influence each other when sucking and discharging the liquid medicament;

(2) through setting up first check valve and second check valve in this scheme, in the medicine entered into the barrel, the refluence can not take place for the medicine, can not pollute the medicine in the medicament bottle like this.

Furthermore, a horizontal pressing plate is arranged at the upper part of the push rod, and anti-skid grains are arranged on the upper surface of the pressing plate. The push plate is convenient to push or pull by arranging the pressing plate, and the auxiliary effect on sucking and discharging the medicament can be achieved.

Further, a tripod is arranged at the bottom of the cylinder body, and a rubber sleeve wraps the lower end of the tripod. The tripod is convenient to support the barrel, and the height of the barrel can be adjusted simultaneously, so that the novel multifunctional barrel is convenient to use.

Furthermore, a spring is connected between the upper part of the piston head and the blind plate. Through setting up the spring, be convenient for difficult range is too big when upwards pulling through the piston head, can prevent that the medicament from getting into the barrel fast and causing the dosage too big.

Furthermore, the lower part of the piston head is provided with a conical rubber head, and the bottom of the inner side of the cylinder body is provided with a concave cavity matched with the rubber head. Through setting up rubber head and cavity, be convenient for arrange the medicament in the barrel to the greatest extent, reduced the loss of medicament, improved the accuracy of medicament volume.

Further, the blind plate is in threaded connection with the inner wall of the barrel, and a rubber pad which can be attached to the barrel is arranged on the outer side of the blind plate located on the threads. Through with blind plate and barrel threaded connection, can dismantle this device fast, be convenient for wash in the barrel.
