Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a device for expanding and draining umbilical cord blood plasma bags. Background Technology

[0002] Umbilical cord blood or plasma bags need to be sampled by puncture with a syringe for inoculation into bacterial culture bottles to detect microorganisms. After sampling, if necessary, the remaining blood or plasma should be transferred to containers such as cryovials.

[0003] Currently, there is a risk of cross-infection when collecting umbilical cord blood. If the original syringe is used again for sampling, the culture medium in the culture bottle may remain in the syringe, causing sample contamination. Frequent replacement of new syringes will increase the cost of consumables, and frequent puncture operations are prone to occupational exposure (such as needlestick injuries). In addition, the original puncture site is small, and the liquid flow rate is slow and easy to spill when poured directly, requiring repeated adjustment of the angle, resulting in low operation efficiency.

[0004] There is an urgent need for a device to expand and drain umbilical cord blood plasma bags to address the technical deficiencies mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a device for expanding and draining umbilical cord blood plasma bags to solve the problem of cross-infection risk mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an umbilical cord blood plasma bag dilation and drainage device, comprising a dilation assembly and a drainage assembly. The dilation assembly consists of a drainage tube, a limiting ring, and a blunt insertion tube. The limiting ring is fixedly connected to the top end of the drainage tube. The drainage assembly includes an extension catheter and an optional flexible tube. A flow control valve is fixedly installed on the optional flexible tube. A connection opening is fixedly connected to the end of the optional flexible tube. A sealing ring is fixedly connected to the inner side of the connection opening. A cryotube is provided below the connection opening. The outside of the drainage tube is provided with anti-slip texture.

[0007] As a further technical solution of this utility model, the main body of the drainage tube is a cylindrical hollow structure, and the blunt insertion tube is connected to the drainage tube in a through manner.

[0008] As a further technical solution of this utility model, the blunt insertion tube adopts a tapered blunt head, and the limiting ring is disposed below the blunt insertion tube.

[0009] As a further technical solution of this utility model, the drainage tube and the extension catheter are connected in a through connection.

[0010] As a further technical solution of this utility model, the extension conduit and the optional hose are connected in a through connection.

[0011] As a further technical solution of this utility model, the flow control valve adopts a press-type clamping structure control valve.

[0012] As a further technical solution of this utility model, both the flaring component and the drainage component are made of medical-grade polypropylene.

[0013] As a further technical solution of this utility model, the connecting opening is threadedly connected to the top end of the freezing tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the umbilical cord blood plasma bag dilation and drainage device not only achieves the function of avoiding cross-infection and reducing costs and risks, but also achieves the function of simple and efficient operation.

[0015] (1) The device is equipped with a flaring assembly, a drainage assembly, an extension catheter, an optional hose, anti-slip texture, a drainage tube, a limiting ring, and a blunt insertion tube. The main body of the drainage tube of the flaring assembly is a cylindrical hollow structure. The anti-slip texture on the surface of the drainage tube can improve the friction of holding the hand during insertion and enhance the stability of insertion. The blunt insertion tube at the top of the drainage tube adopts a conical blunt tip, which is used to insert into the original puncture site of the blood plasma bag and enlarge the aperture to avoid secondary damage or leakage caused by sharp structures. The limiting ring at the bottom of the blunt insertion tube prevents the plasma bag from being damaged due to excessive insertion. The device consists of a flaring assembly, a drainage assembly, and an extension catheter. The dedicated drainage channel is independent of the sampling syringe and does not need to contact the culture bottle, thus eliminating cross-contamination between the sample and the culture medium.

[0016] (2) By setting up a flaring component, a drainage component, an extension catheter and a cryotube, the flaring component and the drainage component are both made of medical-grade polypropylene. The overall consumable volume of the drainage device is only one-fifth of that of a traditional syringe, and the cost is reduced by more than 60%. The blunt insertion tube adopts a conical round head structure design and integrated operation to reduce the number of punctures and reduce the risk of occupational exposure. This structure achieves the function of reducing costs and risks.

[0017] (3) By setting up optional hoses, flow control valves, connecting openings and cryotubes, the flaring assembly can quickly enlarge the original puncture site and extend the catheter directly to the target container. The flow control valve on the optional hose adopts a press-type clamping structure, which can be used to adjust the liquid flow rate. The liquid flow rate is increased by 3 to 5 times. During sampling, umbilical cord blood flows directly into the interior of the cryotube along the optional hose. The connecting opening is closed and connected to the opening of the cryotube, which is not easy to spill during transportation. The operation can be completed by a single person. This structure realizes the functions of convenient and efficient operation. Attached Figure Description

The blunt insertion tube 12 at the top of the drainage tube 10 adopts a conical blunt tip, which is used to insert into the original puncture site of the blood plasma bag and enlarge the aperture to avoid secondary damage or leakage caused by sharp structures. The limiting ring 11 at the bottom of the blunt insertion tube 12 prevents the plasma bag from being damaged due to excessive insertion. The flaring assembly 1, the drainage assembly 2 and the extension catheter 3 are composed of a dedicated drainage channel that is independent of the sampling syringe and does not need to contact the culture bottle, thus eliminating cross-contamination between the sample and the culture medium.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the flaring assembly 1 can quickly enlarge the original puncture site, and the extension catheter 3 can be directly connected to the target container. The flow control valve 5 on the optional tubing 4 adopts a press-type clamping structure, which can be used to adjust the liquid flow rate, increasing the liquid flow rate by 3 to 5 times. During sampling, the umbilical cord blood flows directly into the interior of the cryotube 7 along the optional tubing 4. The connecting opening 6 is closed and connected to the opening of the cryotube 7, making it less prone to leakage during transportation. The operation can be completed by a single person.

[0029] Both the flaring assembly 1 and the drainage assembly 2 are made of medical-grade polypropylene, and the connecting opening 6 is threadedly connected to the top of the cryotube 7.

[0030] Specifically, such as Figure 1 and Figure 3 As shown, both the flaring assembly 1 and the drainage assembly 2 are made of medical-grade polypropylene.

The overall consumable volume of the drainage device is only one-fifth that of a traditional syringe, reducing costs by more than 60%. The blunt insertion tube 12 adopts a conical round head structure design and integrated operation to reduce the number of punctures and reduce occupational exposure risks. The flaring assembly 1 can quickly enlarge the original puncture site, and the extension catheter 3 can be directly connected to the target container. The flow control valve 5 on the optional tubing 4 adopts a press-type clamping structure, which can be used to adjust the liquid flow rate, increasing the liquid flow rate by 3 to 5 times. During sampling, umbilical cord blood flows directly into the cryotube 7 through the optional tubing 4. The connecting opening 6 is closed to the opening of the cryotube 7, making it less prone to leakage during delivery. The operation can be completed by a single person. This structure achieves convenient and efficient operation.
