Description

Functional suction tube for drug administration or drug loading

Technical Field

The utility model relates to a functional straw device which can be used for drug administration or drug loading and can prevent backflow of liquid medicine, in particular to a straw which is suitable for clinical medication of children and old people and solves the swallowing difficulty of medication; is especially suitable for suction tubes for administration of dispersible tablets and granules.

Background

At present, oral administration is the most convenient and accepted administration, and the dosage form is usually tablet or capsule. However, many children have aversion, timidity and resistance to taking medicine, so that the phenomenon that the children cannot take medicine according to the advice of doctors generally exists; patients lying in bed for a long time and old patients are very difficult to take the medicine, which brings great inconvenience to clinical patients. In order to solve the problems of inconvenient clinical medication and dysphagia, some remarkable research results are obtained at present, such as oral liquid preparations such as oral solutions, suspensions and the like, but the problems still exist as follows: the administration dose is difficult to control; part of the medicines have poor stability in liquid and short shelf life; the sustained and controlled release effect achieved by coating cannot be realized, etc. Therefore, the medicine carrying straw technology is developed at the same time, solid medicines are dissolved in the straw to form a liquid preparation when the medicines are taken, and the problems of inconvenience in clinical medication and liquid preparation defects can be effectively solved.

The suction pipe is a cylindrical hollow plastic product, and is mainly used for drinking the beverage in the cup by applying the atmospheric pressure principle. In recent years, the production of the straws has realized the characteristics of good quality, complete variety, high-end innovation and the like, and has a totally-closed clean factory building with GMP food standard, and the produced straws meet all detailed rules of related organization requirements, production process, rule acceptance, basis judgment and the like of international standards of the global plastic straw industry, so that the possibility is provided for designing drug-loaded straws and meeting the medication safety.

Disclosure of Invention

In view of the above, the invention provides a novel medicine-carrying straw, which can be positioned in a straw medicine storage cavity for dissolution by improving the existing structure, so that the medicine dissolution is promoted, the mixing effect of liquid and medicine can be further improved, and the dissolving speed of the medicine is accelerated; meanwhile, the check valve device is used for preventing the liquid medicine from flowing back, so that the retention of the liquid medicine is reduced, and the dosage of the liquid medicine is accurate, clean and sanitary; the upper part and the lower part of the suction pipe both adopt a bendable folding structure, so that the angle of the suction pipe is easy to flexibly adjust, and the medicine taking of the bedridden patient is facilitated.

The medicine carrying straw meets the requirement of children medicine taking compliance, is convenient for the medicine taking mode of special crowds such as people who are difficult to take medicine, and simultaneously expands the clinical medicine taking way.

In order to achieve the purpose, the invention provides the following technical scheme:

a drinking straw, comprising:

the medicine storage cavity of the suction pipe consists of two cylindrical assemblies, the middle body is provided with threads and can be disassembled and opened, and medicines are added through the threads, so that the medicines can be promoted to be dissolved out, and the medicine liquid is uniformly mixed;

the screen structure comprises two screen structures which are respectively arranged at the upper opening and the lower opening of the medicine storage cavity of the suction pipe, so that the tablets or granules are well positioned in the medicine storage cavity to be dissolved, and undissolved medicine particles are prevented from being inhaled to cause throat choking or leaking into a check valve to cause the medicine to be left at other positions to cause inaccurate medicine taking dosage;

the check valve can prevent the backflow of the liquid medicine and forms a semi-closed space together with the wall of the medicine storage and dissolution cavity of the suction tube so as to ensure that the medicine is dissolved in a positioning way;

the flexible telescopic connection straw can be disassembled, can be flexibly stretched and bent at various angles, and is suitable for the medication requirements of bedridden patients.

The beneficial effects of the utility model are that, enable solid preparation location such as dispersible tablet, granule and dissolve in storing up the medicine and dissolving the chamber, shine the network structure and can prevent that undissolved medicine particle from being inhaled and taking place to chock the pharynx or leak into the check valve, liquid medicine backward flow to the container in the check valve can prevent the chamber, clean health and make the measurement of taking medicine accurate, scalable bending connection straw can be adjusted according to clinical demand in a flexible way, and the bed patient of being convenient for uses.

Drawings

Fig. 1 is a schematic structural diagram of the present invention. In the figure 1, a bent telescopic connection suction pipe, 2, a suction pipe medicine storage cavity and 3, a check valve.

Fig. 2 is a schematic view of the check valve structure. In figure 2, the sieve 4, the solid small ball 5, the hollow round table 6 and the connecting part 7 are arranged.

Detailed Description

In the figure 1, (1) is the crooked flexible connection straw, and its pipe diameter is slightly less than (2) the diameter of pipe, can dismantle, assemble, (2) is the straw medicine storage dissolving chamber, makes the medicine location dissolve wherein, (3) stop return valve, has the solid bobble of a regulation radius in the check valve, reaches the non return effect through its action of gravity and hollow round platform radius relation.

In FIG. 2, (4) is a screen, (6) is a hollow round table, (5) is a solid small ball, (5) has a radius between (6) the small round radius and the large round radius of the platform, and the vertical distance between (4) and (6) is smaller than the diameter of the solid small ball, so that the solid small ball is ensured to move only on a vertical surface, when the suction pipe sucks liquid, the check valve is in an open state, the solid small ball is sucked up along with the flow of water, and the water freely passes through the edge of the small ball; when stopping to absorb liquid, the check valve is in a closed state, the small ball falls back into the hollow round table due to the action of gravity, a semi-closed space is formed by the small ball and the wall of the medicine storage dissolving cavity at the moment, and the medicine is dissolved in the (2) to form the check valve. (7) The check valve is connected with the pipe wall as a whole.
