Technical field
The present invention relates to the armarium technical field, relate in particular to the hydrogen peroxide injecting device on the low-temperature plasma sterilizer equipment.
Background technology
Low-temperature plasma sterilizer equipment is widely used in the sterilization of industries such as biology, pharmacy, medical treatment.And hydrogen peroxide is as the biocide of low-temperature plasma sterilizer equipment, and how the safe and reliable sterile chamber that is injected into then becomes the primary problem that solves of low-temperature plasma sterilizer equipment for it.
The hydrogen peroxide that the low-temperature plasma sterilizer of selling in the market uses is injected to bottled formula injection and card box is injected:
(1) bottled formula is injected and is promptly poured hydrogen peroxide into fluid reservoir through measuring container, again hydrogen peroxide is injected the sterile chamber from fluid reservoir, and bottled formula injection mode is divided into the peristaltic pump formula again and injects and self-priming injection; Need the operator to pour hydrogen peroxide into liquid storage when bottled formula is injected and irritate, hydrogen peroxide is a strong oxidizer, and skin is had corrosion, can splash down like misoperation and burn to operator's skin, and the operator is had potential safety hazard.
(2) card box is injected, and the card box of producing with Johson & Johnson is injected to example, and its operation principle is following:
At first will block the casket carriage through cylinder promotion briquetting and depress, again by another cylinder push card casket, two syringe needles are arranged at card casket bottom; The card casket promotes earlier a sealing shroud, and vacuum chamber is communicated with needle tubing, continues pressure again and blocks the capsule card casket that casket gets into syringe needle hydrogen peroxide is housed fully; Hydrogen peroxide in the capsule gets into the sterile chamber through needle tubing, and after hydrogen peroxide was taken out, cylinder returned; Card casket supporting plate and the spring pop into position of card casket through two sides, the left and right sides, whole process is loaded down with trivial details, complicated.
Thereby, to the card box injection mode, how to overcome the deficiency of prior art, realize that hydrogen peroxide injection more simply and easily then becomes the problem that needs solution.
Summary of the invention
Technical problem to be solved by this invention is, rotating disc type low-temperature plasma sterilizer hydrogen peroxide injecting device, and it is loaded down with trivial details to solve existing implant operation, has the problem of potential safety hazard.
For solving the problems of the technologies described above; The present invention provides rotating disc type low-temperature plasma sterilizer hydrogen peroxide injecting device; Comprise that mainly driving cartridge clip 360 degree rotations moves and localized mechanism, what drive the injection needle front-rear reciprocation movement punctures mechanism and control circuit board; Its whole thinking is that the pioneer moves that folder rotation is moved and the location; Behind the hydrogen peroxide capsule in navigating to cartridge clip; Keep cartridge clip fixed, drive injection needle again and thrust the hydrogen peroxide capsule that navigates to, through controlling the liquid-filling valve that is communicated with the sterile chamber; Make hydrogen peroxide inject the sterile chamber, thereby reach the purpose of injecting hydrogen peroxide.

The specific embodiment
For the purpose, technical scheme and the advantage that make invention is clearer, the present invention is done to specify further below in conjunction with accompanying drawing.
Rotating disc type low-temperature plasma sterilizer hydrogen peroxide injecting device is as shown in Figure 1, comprises with lower component: fluid injection window (1), steel ball (2), compression spring (3), steel ball sheath (4), cartridge clip (5), control circuit board (6), clamping plate (7), compression spring (8), front supporting plate (9), base (10), rear carrier plate (11), brake motor (12), liquid-filling valve (13), linear motor (14), back limit switch (15), guide rod (16), slide block (17), spigot nut (18), filter cotton (19), rotating shaft (20), ball bearing (21), front limit switch (22), ball bearing (23), inflation needle (24), injection needle (25).
Said injection needle (25) is fixed on the slide block (17) with inflation needle (24); Injection needle (25) is communicated with liquid-filling valve (13); Liquid-filling valve (13) is communicated with the sterile chamber, and inflation needle (24) tail end is equipped with filter cotton (19), and spigot nut (18) is housed on the slide block (17); Drive spigot nut (18) the source guide rod (16) that is connected with slide block (17) through linear motor (14) and seesaw, as shown in Figure 1.
Said linear motor (14) is fixed on the rear carrier plate (11) with brake motor (12); The screw mandrel of its linear motor (14) is fixed on the front supporting plate (9) through ball bearing (23); The two ends of guide rod (16) are individually fixed on front supporting plate (9) and the rear carrier plate (11), and rotating shaft (20) is crossed logical ball bearing (21) and is fixed on the front supporting plate (9), and the other end is connected with brake motor (12); Front supporting plate (9) is individually fixed on the base (10) with rear carrier plate (11), and is as shown in Figure 1.
Said back limit switch (15) is fixed on the rear carrier plate (11), and front limit switch (22) is fixed on the front supporting plate (9), and is as shown in Figure 4
Said cartridge clip (5) is a disc, and the hydrogen peroxide capsule is equipped with in inside, and the hydrogen peroxide capsule is uniformly distributed in the cartridge clip; The cartridge clip shell posts Magnet and RFID label, and Magnet is positioned at cartridge clip 12 o ' clock positions, its be used for the location, the RFID label is positioned at cartridge clip 6 o ' clock positions, its RFID tag storage cartridge clip hydrogen peroxide capsule quantity information and date of manufacture information.
Said control circuit board (6) is fixed on the fluid injection window (1), and control circuit board (6) has gone up Hall element and the antenna that reads the RFID label information integrated, and the fluid injection window has puncturing hole on (1); Clamping plate (7) clamp cartridge clip (5) through the active force of compression spring (8), make itself and rotating shaft (20) keep the fixed position; Steel ball (2) is fixed in the rotating shaft (20) by steel ball sheath (4), and steel ball (2) blocks cartridge clip (5) through the active force of compression spring (3) simultaneously, and is as depicted in figs. 1 and 2;
