Description

Technical Field

[0001] The utility model relates to the technical field of placenta processing devices, in particular to an umbilical cord collection, cleaning and segmentation integrated bag. Background Art

[0002] Umbilical cord mesenchymal stem cells are mesenchymal stem cells derived from the umbilical cord. They have sub-totipotent differentiation potential and can be induced to differentiate into a variety of tissue cells under specific in vitro and in vivo environments. Umbilical cord mesenchymal stem cells have the common characteristics of stem cells, namely the ability to self-renew, multidirectional differentiation and homing.

[0003] In the prior art, the collected umbilical cord is generally placed in an umbilical cord bottle, and a proper amount of preservation solution is poured into it for sealed refrigerated transportation. Then, the umbilical cord is taken out from the clean bench in the laboratory and transferred to a culture dish or a dissection tray for multiple washings. Then, the umbilical cord is cut into several small pieces for further washing, and finally, the umbilical cord is transferred to a new container for dissection and sampling. The above collection method has the following problems:

[0004] 1. The umbilical cord bottle during the collection process is large in size, occupies more space, and has poor refrigeration effect;

[0005] 2. If the amount of preservation solution in the umbilical cord bottle is too much, it will waste costs and seriously affect the cooling speed. If the amount of solution is too small, the umbilical cord may be exposed to the preservation solution during transportation, affecting cell activity;

[0006] 3. During the subsequent cleaning process and testing, the container was replaced many times and open operations were performed, which greatly increased the risk of contamination. Utility Model Content

[0031] Specifically, Figure 2As shown, a double-layer sealing strip 201 is provided on the inner wall of the bag opening 2, and the bag opening can be sealed by the double-layer sealing strip 201, and a heat sealing portion 202 is also provided on the outer side of the double-layer sealing strip 201 of the bag opening 2, and the bag opening 2 can be sealed by using a heat sealing machine at this position, which can further improve the sealing effect, and a tearing notch 203 is also provided on the left side of the bag opening 2, so as to facilitate tearing the heat sealing portion 202 and the double-layer sealing strip 201 to open the bag opening 2; The cleaning liquid inlet pipe 4 and the cleaning liquid outlet pipe 5 are respectively fixedly connected with an inlet pipe rubber plug 401 and an outlet pipe rubber plug 501, and the inlet pipe rubber plug 401 and the outlet pipe rubber plug 501 are respectively provided with an inlet pipe protection cap 402 and a outlet pipe protection cap 502; the preservation liquid injection pipe 6 is a hose, and an injection pipe rubber plug 601 is provided at the opening of one end of the preservation liquid injection pipe 6, and an injection pipe protection cap 602 is sleeved on the outer side of the injection pipe rubber plug 601.

[0032] like Figure 3 , Figure 4 As shown, the umbilical cord cutter 3 is composed of a first side plate 301 and a second side plate 302, which are respectively fixedly connected to the front and rear inner side walls of the bag body 1, and the two are arranged oppositely and have a length along Figure 1 The left and right sides of the first side plate 301 are distributed on the reference of the view. A blade 3011 is fixedly connected to the left end of the inner wall of the first side plate 301. The length of the blade 3011 is distributed along the front-back direction. Two sets of guard plates 3012 are symmetrically fixedly connected to the left and right sides of the blade 3011. The lengths of the two sets of guard plates 3012 are distributed along a direction parallel to the length of the blade 3011. The distance between the inner end of the guard plate 3012 and the first side plate is greater than or equal to the distance between the inner end of the blade 3011 and the first side plate. That is, Figure 3 In the direction of the view shown, the lower end of the guard plate 3012 is located below the lower end of the blade 3011, so that the blade 3011 is covered by the two sets of guard plates 3012 to prevent the blade 3011 from scratching the umbilical cord or the bag body; two sets of guard plate grooves 3021 are arranged on the left side of the inner wall of the second side plate 302, and the two sets of guard plate grooves 3021 are distributed corresponding to the positions of the two sets of guard plates 3012 and can be used to accommodate the guard plates 3012, and a blade groove 3023 is also arranged on the inner wall of the second side plate 302 located between the two sets of guard plate grooves 3021, and the blade groove 3023 is distributed corresponding to the position of the blade 3011.

[0033] like Figure 5 As shown, two groups of limit blocks 3022 are further provided on the second side plate 302, and the two groups of limit blocks 3022 are respectively located on the front and rear sides of the blade groove 3023. Limit grooves 30111 are provided on the front and rear ends of the blade 3011 in the length direction. The two limit grooves 30111 correspond to and cooperate with the positions of the two limit blocks 3022 respectively. Through the setting of the limit blocks 3022, the blade 3011 can be prevented from sliding in the front and rear directions during the umbilical cord cutting process.

[0034] In addition, in the present embodiment, the first side panel 301 and the second side panel 302 are of the same length and their right ends are flush, the left side guard plate 3012 is located at the leftmost end of the first side panel 301, and the blade 3011 is 2 cm away from the right ends of the first side panel 301 and the second side panel 302. When in use, the umbilical cord can be cut after one end of the umbilical cord is aligned with the right ends of the first side panel 301 and the second side panel 302, thereby limiting the cutting length of the umbilical cord.

[0035] Before using the device, first, in a laboratory sterile environment, inject an appropriately configured sample preservation solution into the bag body 1 through the preservation solution injection tube 6. After the preservation solution is injected, the preservation solution injection tube 6 is heat-sealed with a heat sealer. When the umbilical cord is collected, in the hospital delivery room or operating room, the bag opening 2 is opened, the collected umbilical cord is put into the bag opening 2, and then the bag opening 2 is sealed with a double-layer sealing strip 201. If conditions permit, the heat sealing part 202 can be sealed with a heat sealing machine, and then the bag is refrigerated for transportation.

[0036] When cleaning the umbilical cord in the laboratory, on the clean bench, use a syringe to suck out the collection liquid from the cleaning liquid outlet pipe 5, and use another syringe to inject the cleaning liquid from the cleaning liquid inlet pipe 4 to clean the umbilical cord. Repeat this process several times to clean the outer surface of the umbilical cord. Then suck out all or part of the cleaning liquid, and place one end of the umbilical cord between the first side plate 301 and the second side plate 302 of the umbilical cord cutter 3 through the bag. The one end of the umbilical cord and the right edge of the umbilical cord cutter 3, i.e., the right end of the first side plate 301 and the second side plate 302, are connected. Then, pinch the first side plate 301 and the second side plate 302 with your hands to drive the blade 3011 to cut the umbilical cord, then open the first side plate 301 and the second side plate 302 of the umbilical cord cutter 3 and continue to insert the umbilical cord to cut it, until the umbilical cord is completely cut into small sections of about 2 cm, continue to repeat the cleaning steps, and clean the small sections thoroughly, finally tear open the heat-sealed part 202 and the double-layer sealing strip 201 at the tearing opening 203 to open the bag opening 2, and transfer the umbilical cord to the sterile operating tray for fine umbilical cord dissection.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
