Technical Field

The utility model belongs to the technical field of drainage equipment, and particularly relates to a drainage guide tube and a drainage suite.

Background

After a patient performs an operation such as a minimally invasive breast biopsy, there is a certain probability that hematoma will be caused at the tissue resection site due to excessive bleeding. After hematoma, a blood activating and stasis removing medicine or injection is usually used for eliminating hematoma, and in severe cases, the wound is incised by an operation to release blood stasis, but the wound surface is increased by the incision by the operation, and the healing time is prolonged. Therefore, the bleeding part is usually drained through the drainage tube after the operation at present, so that hematoma is prevented. However, the drainage tube is generally soft, is difficult to place at a bleeding part after operation, and is very inconvenient to operate.

Optionally, a retaining ring is arranged around the tube body on one end of the tube body, an access notch for the drainage tube to pass through is arranged on the retaining ring corresponding to the access slot, and the access notch is communicated with the access slot.

Optionally, the two ends of the tube body are respectively an inlet and an outlet, and the edge of the inlet is a smooth round angle.

Optionally, the length of the pipe body is 65 mm-75 mm.

Optionally, the inner diameter of the pipe body is 4 mm-6 mm.

Optionally, the retainer ring is circular, and the diameter of the retainer ring is 15 mm-20 mm.

Optionally, the width of the inlet and outlet groove is 1 mm-2 mm.

The utility model also provides a drainage kit, which comprises a drainage tube and the drainage guide tube as set forth in any one of the above, wherein the outer diameter size of the drainage tube is smaller than the inner diameter size of the drainage guide tube.

Optionally, the drainage tube is a drainage end, the other end of the drainage tube is a connection end, and two or more drainage ports are formed in the drainage end.

Optionally, the drainage tube is a flexible tube.

As described above, the drainage guide tube and the drainage kit of the present utility model have the following beneficial effects:

the drainage guide tube can be sleeved on the biopsy puncture needle, enters the biopsy site along with the biopsy puncture needle when a biopsy operation is performed, and stays in the biopsy site after the biopsy puncture needle is withdrawn. Since the drainage guide tube is hollow tubular, the drainage tube can easily pass through the drainage guide tube and enter the biopsy site. The tube wall of the drainage guide tube body is provided with an inlet and outlet groove which is used for the drainage tube to pass through. Therefore, after the drainage tube enters the biopsy part, the drainage guide tube can be separated from the drainage tube through the inlet and outlet grooves and then exits the biopsy part, and the drainage tube is reserved at the biopsy part to finish the placement of the drainage tube, so that the difficulty in placing the drainage tube into the biopsy part is greatly reduced, the drainage tube can timely discharge blood and dirt at the wound part, and secondary injury of hematoma to a patient is prevented.

To be able to describe the present utility model in detail, first, the following describes the present utility model in detail:

as shown in fig. 1, this embodiment provides a drainage guide tube, which includes a hollow tube body 1, wherein a tube wall of the tube body 1 is provided with a channel 2 for a drainage tube 9 to pass through, and the channel 2 penetrates through an inner cavity of the tube body 1 and an outer side of the tube body 1. The inlet and outlet groove 2 penetrates through the pipe wall of the pipe body 1 along the axial direction of the pipe body 1, and openings at two ends of the pipe body 1 are communicated through the inlet and outlet groove 2. The drainage guide tube can support human tissues at the focus before drainage, the difficulty of placing the drainage tube 9 into the biopsy part 8 is greatly reduced, the drainage guide tube is conveniently separated from the drainage tube 9 by the inlet and outlet groove 2, and the drainage guide tube is easy to take out after being used.

In the embodiment, the drainage guide tube can be integrally formed by medical grade stainless steel or other high polymer plastics (such as PE), has good corrosion resistance, is easy to disinfect, and is suitable for medical use.

In some embodiments, a retaining ring 3 is arranged around the pipe body 1 on one end of the pipe body 1, an inlet and outlet notch 4 for the drainage pipe 9 to pass through is arranged on the retaining ring 3 corresponding to the inlet and outlet groove 2, and the inlet and outlet notch 4 is communicated with the inlet and outlet groove 2. The two ends of the tube body 1 are respectively provided with an inlet and an outlet, and the edge of the inlet is a smooth round angle 5, which is beneficial to the drainage guide tube to enter the biopsy part 8 and reduces the damage to human body. In this embodiment, the outlet edge of the tube body 1 is provided with a guiding surface 6 with an inclination angle between the guiding surface 6 and the axial direction of the tube body 1, and the guiding surface 6 can guide the drainage tube 9 when the drainage tube 9 enters the tube body 1, so that the drainage tube 9 can be conveniently placed in.

In some embodiments, the length of the tube 1 is 65mm to 75mm. The inner diameter of the pipe body 1 is 4 mm-6 mm. The retainer ring 3 is circular, and the diameter of the retainer ring 3 is 15 mm-20 mm. The width of the inlet and outlet groove 2 is 1 mm-2 mm. In this embodiment, the length of the tube 1 is 67mm. The wall thickness of the pipe body 1 is 1mm, the inner diameter of the pipe body 1 is 4.6mm, and the diameter of the retainer ring 3 is 17mm. The width of the inlet and outlet groove 2 is 1mm.

The utility model also provides a drainage kit, which comprises a drainage tube 9 and the drainage guide tube as any one of the above, wherein the outer diameter size of the drainage tube 9 is smaller than the inner diameter size of the drainage guide tube.

Specifically, the drainage tube 9 is a drainage end, the other end of the drainage tube 9 is a connection end, and two or more drainage ports 11 are formed in the drainage end. The number of the drainage ports 11 is two or more, and after one drainage port 11 is accidentally blocked, the rest of the drainage ports 11 can still continue drainage, so that the drainage reliability is improved.

In the embodiment, the drainage tube 9 is a flexible tube, and when the drainage tube 9 is taken out from the inlet and outlet groove 2, the drainage tube 9 can be flexibly deformed, so that the drainage tube 9 can be taken out conveniently.

In actual use, the drainage guide tube can be sleeved on the biopsy puncture needle, and enters the biopsy site 8 along with the biopsy puncture needle when performing a biopsy operation. As shown in fig. 2, after the biopsy needle is withdrawn, the drainage guide remains in the biopsy site 8. As shown in fig. 3, since the drainage guide tube is hollow tubular, the drainage tube 9 can easily pass through the drainage guide tube into the hematoma 7 in the biopsy site 8. The tube wall of the drainage guide tube body 1 is provided with an inlet and outlet groove 2, and the inlet and outlet groove 2 is used for the drainage tube 9 to pass through. Thus, as shown in fig. 4, after the drainage tube 9 enters the biopsy site 8, the drainage guide tube can be separated from the drainage tube 9 by the access slot 2 and then withdrawn from the biopsy site 8, while the drainage tube 9 is left at the biopsy site 8, completing the placement of the drainage tube 9. The drainage tube 9 is connected with a negative pressure device 10, and the negative pressure device 10 sucks the congestion in the hematoma 7 through the drainage tube 9 so as to achieve the purpose of eliminating the hematoma 7.
