Problems solved by technology

However, when the drug dose is low after long-term use or when only a small amount of liquid is required to load an effective dose of drug, the liquid level in the dispenser container is low and cannot completely cover the liquid inlet of the dip tube
This causes the dip tube to contain an indeterminate amount of gas when it draws the medicine, which leads to insufficient medicine dose in a single dose, and the most critical thing is that the dose of medicine administered each time changes with the change of the gas entering, and each dose cannot Maintain consistent uniformity and accuracy
In the end, it is impossible to give a sufficient amount of medicine under the predetermined number of administrations, and the therapeutic effect cannot be achieved.
[0006] Based on the above background, how to discover, reveal and solve the problem of the uniformity and accuracy of the above-mentioned drug fluid dispenser under the low level of liquid fluid medicine, which has not been disclosed in the existing research field of drug fluid dispensers
[0007] On the other hand, due to the lack of homogeneity and low drug administration accuracy at low levels, discarded low-level psychoactive drugs often have the social risk of being illegally collected and used illegally

Embodiment 1

[0060] This embodiment provides a drug fluid dispenser that maintains the uniformity of drug administration under a low margin, see figure 1 , which includes a metering pump 1 , a cover 2 , a container 3 and a dip tube 4 .

[0061] The metering pump 1 is arranged at the opening of the container 3, and is sealed and fixed by the cover 2.

[0062] The container inner bottom wall 31 of the container 3 is stepped in a high outer part and a lower inner middle part. The inner middle part of the inner bottom wall 31 of the container is provided with a groove 32 by the vertical wall of the step. Through the stepped design, when the medicine has a low balance, it will flow through the steps and converge into the groove 32 under the action of gravity, while the inner cross-sectional area of ​​the groove 32 is significantly reduced, and the medicine with a low balance remains in the groove 32. The deeper the depth, the liquid inlet of the dip tube 4 is completely covered. This makes i...

Embodiment 2

[0066] This embodiment provides a drug fluid dispenser that maintains the uniformity of drug administration under a low margin. The most basic structure is to include a container 3 with an open top, a metering pump 1 installed at the opening of the container 3, and a container located at the opening of the container. Dip tube 4 in 3, the top of dip tube 4 is connected with metering pump 1.

[0067] Such as Figure 2-11 As shown in different specific implementation forms, the container inner bottom wall 31 of the container 3 is provided with a liquid collection chamber by reducing the inner cross-sectional area to increase the depth of the fluid under the same volume, and the bottom liquid inlet of the dipping tube 4 is located at the bottom of the container. The liquid collection chamber is arranged close to the bottom of the liquid collection chamber.

[0068] In a more specific improved embodiment, a groove 32 is provided on the inner bottom wall 31 of the container, and th...

Embodiment 3

[0081] Under the same technical concept as that of Embodiment 1 and Embodiment 2, this Embodiment 3 provides a specific drug fluid dispenser, which has two major technologies of maintaining uniformity of drug administration and good placement stability under low drug balance. Advantage.

[0082] see Figure 13 , The drug fluid dispenser of the present embodiment 3 is mainly composed of a metering pump 1 , a cover 2 , a container 3 , a dipping tube 4 and an outer bottle body 5 .

[0083] The metering pump 1 is sealed and fixed on the upper opening of the container 3 through the cover 2 .

[0084] The dipping tube 4 is located in the container 3 , and its upper part is connected to the metering pump 1 .

[0085] The inner bottom wall 31 of the container 3 is a conical structure with the tip pointing downwards, and the interior of the conical structure constitutes a liquid collection chamber, and the lower apex of the conical structure is the lowest point. The lower end of the...

Abstract

The invention belongs to the technical field of drug fluid distribution. Compared with an injection drug administration way, a device for drugs for external use always stores more drugs, and the drugsare applied in batches in various occasions. The device for drugs for external use always has a long use period and a relatively poor storage condition, requirements for stability of medicaments in the device for drugs for external use are higher, and medicament auxiliary material selection and compatibility of packing materials are key factors which are mainly considered and screened. When the device for drugs for external use is used for multiple times or only a small quantity of liquid is required for loading drugs, dosage delivery is insufficient and/ or differences are large, and a situation that active ingredients degrade is usually associated immediately. Although most cases are as usually known that medicament stability is insufficient and active ingredients degrade to enable a curative effect to get worse, the thought of technicians in the field is restricted. The invention makes an in-depth study to discover a reason for generating an unstable curative effect in another accompanying drug administration utilization process, and on the basis, a novel drug fluid distributor is provided.

Description

technical field [0001] The invention belongs to the technical field of drug fluid distribution, and in particular relates to a drug fluid dispenser capable of maintaining the uniformity of drug administration under a low amount of drug fluid, especially a psychotropic drug nasal sprayer, especially a dexmedetomidine nasal spray sprinkler. Background technique [0002] External medicine (skin, mucous membrane, cavity, etc.) requires a variety of drug delivery devices, and fluid dispensers are one of them. Common fluid dispensers such as nasal sprays and the like. [0003] Different from the way of injecting drug administration, relatively large amount of drugs are usually stored in external drug devices and administered in batches in various occasions not limited to hospitals. Drugs in external drug devices often have a long service life and relatively poor storage conditions, which put forward higher requirements for the stability of drugs in external drug devices. Therefo...
