Description

It is a kind of can automatic heat sterilization vaccinating pen

Technical field

The utility model relates to the technical field of microbial inoculant tool, more particularly to it is a kind of can automatic heat sterilization connect Kind pen.

Background technique

Vaccinating pen generally comprises oese and two kinds of transfer needle, is a kind of common microbionation tool, and oese is main For separation scribing line of the bacterium on solid medium, it is also used for the microbionation of fluid nutrient medium, transfer needle is mainly used for wearing Pierce inoculated bacteria.

Oese or transfer needle when in use, need to redden and could sterilize by alcolhol burner heating calcination, in practical operation Middle because that need to use alcolhol burner open fire, there are some potential safety problemss, and oese or the primary inoculation of the every completion of transfer needle will be used Alcolhol burner sterilizes, and sterilizing number is frequent, and alcolhol burner is generally just placed on side, and operator, which is easy to collide with, overturns alcohol Lamp causes personnel's scald etc., and there are biggish security risks, in addition, oese or transfer needle are by ring (needle), metal handle and insulation Handle composition, length is longer, it has not been convenient to carry storage, a shorten length it is therefore desirable to develop, is convenient for carrying and can be without bright The vaccinating pen of automatic heat sterilization in fiery situation.

Utility model content

In view of the above-mentioned state of the art, the technical problem to be solved by the utility model is to provide one kind can be automatic The vaccinating pen of heat sterilization, the vaccinating pen can shorten length, be convenient for carrying, and the automatic heat sterilization of energy, easy to operate.

Technical solution adopted by the utility model to solve the above technical problems is as follows: it is a kind of can automatic heat sterilization inoculation Pen, including inoculation head, metal handle and insulation handle, the metal handle and the scalable connection of insulation handle, the inoculation head are fixed on gold Belong to pommel portion, be provided with power supply in the insulation handle, which is connect by conducting wire with inoculation head, and the insulation handle is equipped with control The switch of power supply connection processed, the inoculation head are heating wire.

Further, the inoculation head is nichrome heating wire, the both ends of the inoculation head by conducting wire and power supply just, Cathode connection.

Further, the inoculation head is oese or transfer needle.

Further, the fixed plate that can fix inoculation head is equipped in the metal handle, the inoculation head is plugged in fixed plate On, the both ends which connect with conducting wire are placed on outside fixed plate.

Further, in insulation handle inner tip, the switch is arranged on insulation handle side wall, described for the power supply setting The top of insulation handle is equipped with the end cap of removable power supply.

Further, the insulation handle is equipped with the headgear of protection inoculation head, and the headgear and insulation handle are clamped.

Further, the insulation handle inner wall is equipped with the baffle ring of limit metal handle, close metal handle in the insulation handle End is provided with limit hole, and the metal handle is equipped with the salient point cooperated with limit hole.

Compared with the prior art, the advantages of the utility model are: the utility model is in insulation handle by being arranged power supply, And the sterilizing of alcolhol burner open fire is avoided so that power supply directly heats inoculation head and sterilizes as inoculation head using heating wire Security risk, and by self-powered, remove the trouble that plug connection is powered from, it is easy to use, in addition, metal handle and insulation handle Scalable connection, when storage, can shorten length, reduce the occupancy in space, easy to carry.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the structural schematic diagram of another embodiment of the utility model；

Fig. 3 is the structural schematic diagram after the utility model storage；

As shown, 1 metal handle, 2 insulation handles, 3 power supplys, 4 conducting wires, 5 switches, 6 fixed plates, 7 end caps, 8 headgears, 9 baffle rings, 10 salient points, 11 oeses, 12 transfer needles.

Specific embodiment

As shown in Figure 1-3, it is a kind of can automatic heat sterilization vaccinating pen, including inoculation head, metal handle 1 and insulation handle 2, institute State metal handle 1 and the scalable connection of insulation handle 2, i.e., metal handle 1 can in insulation handle 2 telescopic slide, in use, can be from exhausted It stretches out in edge handle 2, when not in use, can take in insulation handle 2, shorten the length of vaccinating pen, reduce space hold, the inoculation Head is fixed on 1 end of metal handle, is provided with power supply 3 in the insulation handle 2, which is connect by conducting wire 4 with inoculation head, institute It states insulation handle 2 and is equipped with the switch 5 that control power supply 3 is connected to, the inoculation head is heating wire.

Preferably, the inoculation head is nichrome heating wire, and general inoculation head is made with platinum wire to be preferred, because it is hard Degree is suitable for easily propagating heat dissipation, cooling fast after flame sterilization, is not easy to get rusty durable, but price is particularly expensive, so using Nichrome heating wire replaces, affordable, and electrified regulation effect is good, and the both ends of the inoculation head pass through conducting wire 4 and power supply 3 Positive and negative electrode connection, the inoculation head be oese 11 or transfer needle 12.

Preferably, it is equipped with the fixed plate 6 that can fix inoculation head in the metal handle 1, the inoculation head is plugged in fixed plate 6 On, the both ends which connect with conducting wire 4 are placed on outside fixed plate 6, facilitate wiring.

Preferably, the setting of power supply 3 is in 2 inner tip of insulation handle, and the switch 5 is arranged on 2 side wall of insulation handle, institute The top for stating insulation handle 2 is equipped with the end cap 7 of removable power supply 3, is convenient for changing power supply.

Preferably, the insulation handle 2 is equipped with the headgear 8 of protection inoculation head, and the headgear 8 and insulation handle 2 are clamped, due to connecing The kind easy collision deformation of head will be inoculated with head-shield inside so can connect a headgear 8 in insulation handle 2 when storage, Protection is formed, its deformation that collides in storage, carrying is prevented.

Preferably, 2 inner wall of insulation handle is equipped with the baffle ring 9 of limit metal handle 1, prevents 1 transition of metal handle from protruding into absolutely It in edge handle 2, is not easy to extract out, is provided with limit hole (not shown), the metal handle 1 close to 1 end of metal handle in the insulation handle 2 It is equipped with the salient point 10 cooperated with limit hole, salient point 10 and limit hole cooperation can prevent metal handle 1 from skidding off insulation handle 2.

In use, first removing headgear 8, then metal handle 1 is extracted out from insulation handle 2, until salient point 10 and limit hole card Limit is connect, then touch switch 5 first gives inoculation head heat sterilization, can carry out inoculation operation after cooling, be inoculated with all may be used every time It is easy to use to carry out heat sterilization by touch switch 5, when storage, metal handle 1 is contracted in insulation handle 2, so that metal The end of handle 1 offsets with the baffle ring 9 in insulation handle 2, then puts on headgear 8, occupies little space, and can protect inoculation head, It is easy to carry.

Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations； Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of skill in the art that its according to It is so possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is replaced on an equal basis It changes；And these are modified or replaceed, various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution Spirit and scope.
