Automatic dryer for blood collection tubes

Abstract

The invention discloses an automatic dryer for blood collection tubes. The automatic dryer comprises a drying module, a transmission set, an air control device, an electrical control device, an operation panel and a rack. The drying module comprises a heating box, a drying head, a drive unit and a drying support. The transmission set and the operation panel are both connected with the air control device and the electrical control device. The heating box is connected with the air control device. The drying head and the drive unit are both connected with the electrical control device. The drying heat is connected with the drive unit. An air pipe is connected between the heating box and the drying head. The drying head comprises a plurality of spray needles, a heat-preserving flow-guiding cavity and a flow-guiding distribution structure. The transmission set is provided with a tray sensing sensor and a tray stop device. By means of the automatic dryer, blood in the dried vacuum blood collection tubes can be fully fused with a reagent in a contact mode, the effect of medicament is maximized, more precise technical information is provided for clinical diagnosis, diagnostic accuracy is improved, and misdiagnosis risks are reduced.

Description

technical field [0001] The invention relates to a drying machine, in particular to an automatic drying machine for blood collection tubes. Background technique [0002] At present, most of the existing vacuum blood collection tube production equipment does not have an independent dryer. , K3, Na2, Lithium Heparin, Sodium Heparin, Sodium Fluoride Potassium Oxalate, etc.), directly pump the cap and vacuumize. [0003] However, because the droplets in the tube are affected by gravity or vibration during storage or transportation, the droplets will slide down and accumulate at the bottom of the test tube, and bacteria can easily breed in a humid environment. Due to the constraints of cost, site, technology, raw material quality, cycle, etc., there is currently no ideal vacuum blood collection tube for drying treatment, which means that the health and safety of the blood collection tube cannot be guaranteed. For hospitals, there is a big problem. risk; moreover, the liquid medi...

[0003] However, due to the influence of gravity or vibration during storage or transportation, the droplets in the tube will slide down and accumulate at the bottom of the test tube, and bacteria are easy to breed in a humid environment

Due to the constraints of cost, site, technology, raw material quality, cycle, etc., there is currently no ideal vacuum blood collection tube for drying treatment, which means that the health and safety of the blood collection tube cannot be guaranteed. For hospitals, there is a big problem. risk; moreover, the liquid medicine is deposited at the bottom of the test tube, and the active ingredients of the medicine will also accumulate at the bottom of the test tube, which is not conducive to the full fusion of the medicine and the blood during the blood test, or the fusion is not uniform, which will have an adverse effect on the test results

[0004] Although a few dosing machines currently have a drying head, they only have one drying head. The drying head of the existing equipment simply heats the compressed air through the electric heating tube and blows it out through 100 blowing tubes. Special fluid analysis design, the air volume at the air outlet is not uniform, and the temperature is not uniform, some test tubes cannot even be effectively dried within the specified time, and the other part of the test tubes may be caused by the high temperature of the drying gas. Affected, invalid or even deformed test tubes, resulting in inconsistent drying effect of 100 test tubes, although it can play a drying role to a certain extent, but the drying effect cannot meet the requirements at all; and a single drying head can only Drying with one tray is inefficient; a single drying head uses a cylinder as a drive unit, and cannot adjust the speed or height. Not only is the drying effect poor, but the life of the cylinder is short, and the utilization rate of electric energy is low; The aluminum acid material is used as the heat insulation material of the heating box, and the aluminum silicate is an industrial heat insulation material, which may cause industrial dust to enter the test tube and cause pharmaceutical pollution when used in the production of medical equipment

[0005] In addition, at present, the dosing equipment for a single drying head only uses industrial-grade oil-water separators when using compressed air, and the filtration accuracy can only reach above 40 microns, and its filtration accuracy is far below the medical and sanitary level. Water, oil, dust particles, and even bacteria or heat sources cannot be reliably filtered, which can contaminate pharmaceuticals during production and even adversely affect blood test results

In addition, a single drying head uses an ordinary electromagnetic contactor as the on-off control device of the heating tube. The disadvantage of the electromagnetic contactor is that it is noisy and has contacts. The head is melted, and the heating tube cannot be cut off, which will cause the air to be continuously heated and uncontrolled, which will quickly burn out the heating tube; at the same time, the temperature of the drying gas will rise sharply, which will damage the medicine and blood collection tubes
