Current deep-low-temperature storage bag is on the market by comprising bag, label bag, two pass joints and sample feeding pipe, and label bag is arranged on the bottom of bag, and two pass joints are two, are all arranged on the top of bag, and sample feeding pipe is arranged between two two pass joints.The deep-low-temperature storage bag of this structure has following deficiency: 1, be provided with separately label bag, make storage bag overall volume larger; 2, sample feeding pipe is arranged between two two pass joints, owing to stretching in bag and with bag inside and communicate in one end of two pass joints, during air in discharge storage bag, be easy to air to be entered in two pass joints and can not emptying, affect the preservation quality of navel blood stem cell; 3,, when sampling detects, normally rule of thumb judgement samples consumption, can not accomplish quantitative sampling.
Utility model content
For above-mentioned deficiency of the prior art, the utility model provides a kind of navel blood stem cell deep-low-temperature storage bag that is easy to before frozen air in emptying bag as far as possible.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of navel blood stem cell deep-low-temperature storage bag, comprise bag, two pass joints and sample feeding pipe, two pass joints are arranged on the top of bag, its one end communicates with in bag, the other end stretches out outside bag, described sample feeding pipe is arranged on the top of bag and the position of close bag edge edge sealing line, and one end of sample feeding pipe communicates with in bag, and the other end is for being communicated with exterior line.
Further, on described sample feeding pipe, be provided with volume markings.
Further, described volume markings is the indentation being arranged on sample feeding pipe outer wall.
Further, described sample feeding pipe is split into the separate sealing tubule of multistage.
Further, in described two pass joints, be fixed with sealing film, one end that two pass joints stretch out bag is provided with silicon rubber cup.
Further, described bag is provided with label sticking region.
Further, also comprise suppending hole, described suppending hole is arranged on the bottom of bag.
Further, also comprise outer protective bag, described bag is encapsulated in outer protective bag.
With respect to prior art, the utlity model has following beneficial effect:
1, the utility model is arranged on the top of bag and the position of close bag edge edge sealing line by sample feeding pipe, freezing front by bag to 45 ° of the lopsidedness that sample feeding pipe is set, make air concentrate on sample feeding pipe place, air in emptying bag as much as possible, thus the freezing and damage to cell in course of defrosting in the future reduced.
2, volume markings is set on sample feeding pipe, realizes navel blood stem cell is carried out to fixed quantity sampling detection, avoided the waste of navel blood stem cell.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the storage bag structural representation with outer protective bag.
Wherein, 1 is suppending hole, and 2 is label sticking region, and 3 is bag, and 4 is two pass joint a, and 5 is two pass joint b, and 6 is sample feeding pipe, 7 main sample introduction switches, and 8 is standby injection port switch, and 9 is standby injection port, and 10 is main injection port, and 11 is outer protective bag.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to Fig. 1 ~ Fig. 2: navel blood stem cell deep-low-temperature storage bag comprises bag 3, two pass joints and sample feeding pipe 6.Two pass joints are two, are respectively two pass joint a4 and two pass joint b5.Two two pass joints are all arranged on the top of bag, and its one end communicates with in bag, and the other end stretches out outside bag.External part at two pass joints is provided with silicon rubber cup, in two pass joints, is fixed with sealing film, in order to isolated extraneous air, guarantees to process all the time germ-free condition in bag.When needs are exported navel blood stem cell, can use aseptic utensil puncture sealing film and be communicated with bag, thus output navel blood stem cell.
Sample feeding pipe 6 is arranged on the top of bag 3 and the position of close bag 3 edge edge sealing lines.One end of sample feeding pipe 6 communicates with in bag 3, and the other end is for being communicated with exterior line.Sample feeding pipe 6 can be arranged on the position near bag 3 left side edge edge sealing lines, also can be arranged on the position near bag 3 right side edge edge sealing lines.In the present embodiment, sample feeding pipe 6 is arranged on the position near bag 3 left side edge edge sealing lines.In use, to 45 ° of the lopsidedness that sample feeding pipe 6 is set, make air concentrate on sample feeding pipe 6 places bag 3, air in emptying bag as much as possible, thus reduce the freezing and damage to navel blood stem cell in course of defrosting in the future; Avoided sample feeding pipe 6 to be arranged between two two pass joints and be difficult for draining the drawback of air in bag.
On sample feeding pipe 6, be provided with volume markings.Volume markings can be arranged on the indentation on sample feeding pipe 6 outer walls, can be also to adopt mode of printing to be printed on the volume markings line on sample feeding pipe 6, can also be one-body molded with sample feeding pipe 6 and protrudes from the salient line of sample feeding pipe 6 outer walls.On sample feeding pipe 6, volume markings is set, is convenient to navel blood stem cell in bag to carry out quantitative sampling detection, avoid the waste of navel blood stem cell.
In order to be further convenient to that navel blood stem cell in bag is carried out to fixed quantity sampling, detect, in the present embodiment, sample feeding pipe 6 is split into the separate sealing tubule of multistage.Multistage seals separate between tubule and does not communicate.During making, can be first according to the number of times and the volume that need sampling to detect in the future, volume markings is set on sample feeding pipe 6 and needs the heat seal position of heat seal; Navel blood stem cell is injected bag 3 interior after, make navel blood stem cell be full of sample feeding pipe 6, then adopt heat-sealing machine to carry out heat seal in heat seal position, sample feeding pipe 6 is divided into the separate sealing tubule of multistage.When needs to bag in navel blood stem cell sample while detecting, only need to extract an intratubular navel blood stem cell of sealing at every turn, realized the fixed quantity sampling to navel blood stem cell.
Bag 3 is provided with label sticking region 2, this label sticking region 2 can be arranged on the convenient optional position of observing on bag 3, during use directly by label sticking on label sticking region 2, when guaranteeing that it has recognition reaction, reduced the volume of whole storage bag.In the bottom of bag 3, be provided with suppending hole 1, when easy to use, hang.
For storage bag is protected, prevent that bag 3 from being scratched or the label pasted drops, the utility model also comprises outer protective bag 11, this outer protective bag is by 3 encapsulation of protective bag bag within it.During making, bag is loaded in outer protective bag, then the opening of outer protective bag 11 is adopted to heat-sealing machine heat seal edge sealing.
Exterior line comprises injection port and the pipeline that is connected injection port and sample feeding pipe 6.Injection port comprises main injection port 10 and standby injection port 9, is provided with main injection port switch 7 on the pipeline between main injection port 10 and sample feeding pipe 6, is provided with standby injection port 8 on the pipeline between standby injection port 9 and sample feeding pipe 6.
Finally it should be noted that, above embodiment is only in order to the technical solution of the utility model to be described but not restriction technologies scheme, although applicant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or are equal to replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present utility model.
