Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical equipment, and specifically relates to a liquid drug supply device. Background Technology

[0002] Liquid pharmaceutical supply systems are specialized equipment used for storing and transporting liquid pharmaceuticals. Current systems have limitations in storage capabilities. During storage, pharmaceuticals are susceptible to the effects of oxygen and microorganisms. The presence of oxygen can cause chemical reactions in some oxidation-sensitive pharmaceuticals, leading to degradation of active ingredients and reduced efficacy, such as those containing vitamin C or ferrous ions. Microorganisms can easily proliferate in suitable oxygen environments, contaminating the pharmaceuticals and affecting their quality and safety. To address these issues, the conventional approach is to add preservatives to the storage tank to inhibit microbial growth. However, adding preservatives may introduce new chemical substances that can affect certain additive-sensitive pharmaceuticals, altering their chemical properties or causing adverse reactions. Furthermore, strict temperature and humidity control of the storage environment requires additional equipment investment and continuous energy consumption, increasing operating costs and management complexity. Therefore, a new structure is needed to solve these technical problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3As the first embodiment of this utility model: a liquid medicine supply device, including: a base frame assembly and a liquid storage assembly, the upper surface of the base frame assembly is equipped with a liquid storage assembly for storing liquid medicine through a bottom shell 130, the base frame assembly includes a base frame body 100 for mounting the bottom shell 130, the upper surface of the base frame body 100 is equipped with a mounting plate 120, the bottom shell 130 is equipped with a liquid dispensing assembly, the liquid storage assembly includes a conical cylinder 200 and a liquid storage tank 210, the upper surface of the conical cylinder 200 is equipped with the liquid storage tank 210, and the outer surface of the liquid storage tank 210 is equipped with a feed pipe 250 and a vacuum component;

[0022] A base frame body 100 is installed at each of the four corners of the lower surface of the mounting plate 120. A fixing frame 110 is installed between the base frame bodies 100. A bottom shell 130 is installed on the upper surface of the mounting plate 120. A receiving cavity is provided inside the bottom shell 130. A conical cylinder 200 is installed at the center of the upper surface of the bottom shell 130.

[0023] The opening of the conical cylinder 200 gradually decreases from top to bottom. The diameter of the opening on the upper surface of the conical cylinder 200 matches the diameter of the opening at the lower end of the liquid storage tank 210. The liquid storage tank 210 is installed on the side surface of the conical cylinder 200 away from the bottom shell 130. The feed pipe 250 is installed on the lower edge of the outer surface of the liquid storage tank 210. A one-way valve is provided at the connection between the feed pipe 250 and the liquid storage tank 210.

[0024] During use, the user first uses an external liquid supply device and then feeds the liquid into the storage tank 210 via the feed pipe 250. After the liquid enters the storage tank 210, the user needs to operate the device to create a gap between the upper surface of the liquid supply device and the upper surface of the storage tank 210. After the liquid is supplied, the user can activate the vacuum device to draw air from the top of the storage tank 210, creating a vacuum state inside the tank. This vacuum is not a complete vacuum (this device is suitable for storing non-aerobic liquids; aerobic liquids are not suitable for this device). Due to the conical cylinder 200's wide-at-the-top and narrow-at-the-bottom design, gravity is used to achieve efficient liquid flow and complete emptying. The liquid outlet reduces residue waste and enhances the stability of the bottom liquid outlet pressure. The vacuum device creates a negative pressure environment by drawing air, effectively inhibiting drug oxidation, volatilization, and microbial growth, thus extending the shelf life.

[0025] Please see Figures 1 to 3As a second embodiment of this utility model: based on the description in the above embodiments, further, the end of the feed pipe 250 away from the storage tank 210 is connected to an external drug supply device, and the vacuum component includes a vacuum tank 240, a vacuum tube 230 and a vacuum machine 220. The vacuum machine 220 is installed on the outer surface of the storage tank 210, the vacuum tank 240 is installed on the upper surface of the storage tank 210, and the vacuum tube 230 is installed between the vacuum tank 240 and the vacuum machine 220.

[0026] The vacuum extraction end of the vacuum component is located at the top inside the liquid storage tank 210. The liquid outlet assembly includes a liquid outlet cylinder 300 and a liquid outlet pipe 310. The liquid outlet cylinder 300 is installed at the center of the upper surface inside the bottom shell 130. The liquid outlet cylinder 300 is aligned with the lower end of the conical cylinder 200.

[0027] A liquid outlet pipe 310 is installed at the lower end of the liquid outlet cylinder 300. The liquid outlet pipe 310 has an L-shaped structure. The end of the liquid outlet pipe 310 away from the liquid outlet cylinder 300 penetrates the outer surface of the bottom shell 130. A liquid outlet valve is installed on the outer surface of the liquid outlet pipe 310.

[0028] An arc-shaped door panel 260 is damped and sealed to the outer surface of the liquid storage tank 210, and the outer side of the arc-shaped door panel 260 is sealed to the liquid storage tank 210.

[0029] In use, after the liquid medicine is stored inside the storage tank 210 through the operation steps of the first embodiment, when the user needs to use the liquid medicine, the user can open the dispensing valve on the outer surface of the dispensing pipe 310, so that the dispensing pipe 310 and the dispensing cylinder 300 can discharge the liquid medicine inside the storage tank 210 for use. After dispensing the required liquid medicine, the dispensing valve is closed, and then through the operation steps of the first embodiment, a vacuum negative pressure state is formed inside the storage tank 210 by the vacuum component, so that the liquid medicine is better preserved inside the storage tank 210. When the liquid medicine inside the storage tank 210 is used up, the user can open the arc-shaped door panel 260 on the outer surface of the storage tank 210 (the outer edge of the arc-shaped door panel 260 is provided with a medical high-sealing sealing ring at the contact point between the abutment of the storage tank 210, so that the air...) Gas and liquid medicine will not leak from the connection of the arc-shaped door panel 260. As for the structure of the high-sealing sealing ring, it is existing technology and users can choose according to actual use (it will not be described in detail here). After opening the arc-shaped door panel 260, users can clean the storage tank 210 and the dispensing component to prevent the liquid medicine stored later from mixing with the current residual liquid medicine and causing an impact. Since the dispensing cylinder 300 is a core transition component, it can buffer the pressure fluctuation of the liquid medicine through the internal bending flow channel design. Combined with the conical cylinder 200 structure of the storage component, it can achieve smooth flow and centralized collection of the liquid medicine medicine and avoid the interference of residue and air bubbles (the ambient temperature and humidity of the whole device will also affect the liquid medicine medicine stored in the storage tank 210. Users can choose the appropriate indoor temperature and environment according to the actual situation).

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
