Sealing mixing storage device for siliconizing fluid of medical syringe needle

Abstract

The invention relates to a sealing mixing storage device for a siliconizing fluid of a medical syringe needle. The sealing mixing storage device comprises an oil tank, a one-way pressure balance valve, a controllable oiling nozzle, an oil draining pipe, an oil draining valve and a stirring device, wherein the controllable oiling nozzle is arranged on the oil tank and is communicated with an inner chamber of the oil tank; the treating fluid is injected into the oil tank through the controllable oiling nozzle; the one-way pressure balance valve is arranged on the oil tank and is communicated with an air chamber of the inner chamber of the oil tank; one end of the oil draining pipe is communicated with the bottom of the inner chamber of the oil tank; the other end of the oil draining pipe is communicated with the outside through the oil draining valve; a stirring component in the stirring device is arranged in the treating fluid in the oil tank. The sealing mixing storage device can eliminate the volatilization of diluent in the treating fluid and can guarantee the uniform mixing of the treating fluid.

Description

technical field [0001] The invention relates to the production technology of medical needles, in particular to a siliconization treatment device for medical needles, more specifically a storage device for siliconization treatment liquid for medical needlepoints. Background technique [0002] In the production process of medical needles, the needles must be siliconized, that is, the surface of the needles is coated with a mixture of silicone oil and HCFC-141b diluent. Among them, the function of HCFC-141b diluent is to dilute the concentration of silicone oil. After coating It will gradually volatilize and form a uniform silicone oil film on the surface of the needle, which can improve the sharpness of the needle tip and reduce the puncture resistance. The existing medical needle siliconization treatment liquid supply system such as figure 1 As shown, it includes an open oil storage tank, an adjustable oil delivery device, and a siliconized treatment pool. The adjustable oil...

Problems solved by technology

[0005] In the purification workshop of medical needle point production, the purification air-conditioning air supply system is used. The HCFC-141b volatilized during the siliconization process is accumulated in the workshop. Static sparks generated in the air can easily cause explosions or fires, directly affecting the safety of workers and property of the enterprise, and there are serious safety hazards

At the same time, when the diluent HCFC-141b volatilizes, the concentration of silicone oil will be too high, making the thickness of the silicone oil film formed on the needle tip exceed the standard, which not only affects the siliconization quality of the needle tip, but also increases the consumption of silicone oil, directly increasing the siliconization of the needle tip Disposal costs, HCFC-141b discharge into the air will destroy atmospheric ozone, serious environmental pollution
