Double-tube type drainage preset tube for abdominal cavity perfusion

Abstract

The invention provides a double-tube type drainage preset tube for abdominal cavity perfusion. The tube comprises a reserved tube fixed to the abdominal cavity of a patient and a perfusion connecting tube inserted into the reserved tube, a perfusate discharging cavity is formed in the bottom of the reserved tube, and at least two perfusate discharging hole channels are formed in the side wall of the perfusate discharging cavity. The perfusate discharging hole channels are communicated with the upper perfusate channel in the perfusate connecting pipe, so that perfusate in the perfusate equipment is fed into the perfusate discharging cavity; an elastic rubber sleeve for sealing the perfusate discharge cavity is arranged at the bottom of the perfusate discharge cavity, the elastic rubber sleeve is formed by splicing two symmetrical semi-conical silica gel overturning pieces, and the elastic rubber sleeve is driven by the driving structure to be opened and closed, so that the blocked reserved pipe is dredged. The elastic rubber sleeve which is controlled to be closed and opened by the driving structure is arranged at the bottom of the reserved pipe, in the closing and opening process, dredging of blockage of the preset pipe is achieved, operation is easy and convenient, wounds of a patient cannot be damaged, and discomfort of the patient cannot be caused.

Description

technical field

[0001] The invention relates to peritoneal perfusion therapy in a cancer treatment method, in particular to a double-tube drainage preset tube for peritoneal perfusion. Background technique

[0002] Peritoneal perfusion chemotherapy, referred to as peritoneal perfusion, is one of the common chemotherapy methods for the treatment of advanced tumors in the pelvis and abdominal organs. It is generally divided into hyperthermic perfusion and conventional perfusion. The principle is simple. After that, chemotherapeutic drugs or drugs for eliminating peritoneal effusion are instilled into the peritoneal cavity through the drainage tube; different from hot perfusion, conventional perfusion is to inject the drug into the abdominal cavity, and then bind the drainage tube so that the drug remains in the patient's peritoneal cavity for a period of time. It is about 24 hours, so that the patient can fully absorb the drug. In order to promote the absorption of the drug, d...

Embodiment 1

[0037] Such as Figure 1-8 As shown, a double-tube drainage preset tube for peritoneal perfusion includes a reserved tube 1 fixed in the patient's abdominal cavity and a perfusion connecting tube 2 inserted into the reserved tube 1, and the upper end of the perfusion connecting tube 2 passes through the reserved tube. The top of the tube 1 is connected to the perfusion equipment, and the bottom of the reserved tube 1 has a cylindrical perfusate discharge cavity 101, and at least two perfusate discharge channels 108 are arranged on the side wall of the perfusate discharge cavity 101, and these perfusate The discharge hole 108 communicates with the upper perfusate channel 201 in the perfusion connecting pipe 2, so as to send the perfusate in the perfusion device into the perfusate discharge chamber 101; an elastic rubber sleeve is provided at the bottom of the perfusate discharge chamber 101 to close it 3. The elastic rubber sleeve 3 is spliced ​​by two symmetrical semi-conical ...

Embodiment 2

[0042] This embodiment is an improvement made on the basis of embodiment 1, its main structure is the same as that of embodiment 1, and the improvements are as follows: Figure 3-8 As shown, the inner wall of the silica gel flipping sheet 301 is provided with a silica gel blocking sheet 302, the number of the silica gel blocking sheet 302 corresponds to the number of the perfusate discharge channels 108 one by one, and each silica gel blocking sheet 302 slides Set in the chute on the inner wall of the perfusate discharge chamber 101, when the two silica gel flippers 301 are closed, each silica gel sealing piece 302 will close the corresponding perfusate discharge channel 108, when the two silica gel flippers 301 are opposite to each other When moving to form the perfusion channel 304 , the silica gel blocking piece 302 moves downward along the chute, so that the perfusate discharge hole 108 communicates with the perfusate discharge chamber 101 .

[0045] This embodiment is an improvement made on the basis of embodiment 2, its main structure is the same as that of embodiment 2, and the improvements are as follows: Figure 3-6 As shown, the top of the silica gel blocking sheet 302 is obliquely provided with a deflector 303 facing the perfusion channel 304, and when the silica gel blocking sheet 302 moves down to the lowest position along the chute, the deflector 303 and the perfusate The discharge hole 108 is connected to each other, and the perfusate discharged from the perfusate discharge hole 108 is guided to flow directly into the perfusion channel 304 .

[0046] In this embodiment, the cross-section of the guide plate 303 is arc-shaped.
