The base plate 2 is made of medical titanium alloy. Can prevent the fine needle from penetrating too deeply into the abdominal cavity and injuring the organs in the abdominal cavity.

During the use, with tumour patient's anesthesia back, the piece of cloth is spread in conventional belly disinfection, opens belly skin, exposes subcutaneous fat, fixes the chemotherapy device at belly subcutaneous fat layer through fixed orifices 4 with the stylolite, penetrates transfer line 3 in the abdominal cavity, through transfer line 3 scales, calculates the degree of depth that adjustment transfer line 3 went into the abdominal cavity, injects heparin salt solution through sealed lid, and the guarantee chemotherapy device is unobstructed, sews up skin. When in abdominal cavity chemotherapy, the conventional skin disinfection is firstly carried out, the needle of the infusion apparatus is vertically penetrated into the skin to penetrate through the sealing cover 1 of the subcutaneous chemotherapy pump and reach the bottom plate 2, the prepared chemotherapy medicine is instilled into the chemotherapy pump through the infusion apparatus, and the chemotherapy medicine reaches the abdominal cavity through the infusion tube 3; after the chemotherapy is finished, the infusion apparatus is pulled out, and then the heparin sodium solution is injected into the chemotherapy device through the needle of the infusion apparatus, so that the infusion tube is prevented from being blocked. When the ascites or the redundant chemotherapy drugs in the abdominal cavity need to be pumped out, the ascites or the chemotherapy drugs can be pumped out by the syringe through the chemotherapy pumps.

Compared with the prior art, the utility model has the advantages of it is following:

1. the sealing cover of the chemotherapy pump is made of medical silicon rubber, can resist the repeated puncture of the injection needle, and ensures repeated intraperitoneal chemotherapy.

2. The edge of the bottom plate of the chemotherapy pump is provided with a fixing hole which protrudes outwards and penetrates up and down, so that the chemotherapy pump can be fixed under the skin through a suture line to prevent the chemotherapy pump from contacting the outside, thereby effectively preventing infection and ensuring long-time use.

3. The infusion tube is divided into four small infusion tubes by the cross partition, so that the condition that the whole chemotherapy device cannot be used due to the blockage of one infusion tube can be prevented.

4. The edge of the small infusion tube is provided with 4 side grooves, the contact area of the side grooves and the outside is larger, and the condition that the small infusion tube is blocked due to liquid solidification and tumor growth wrapping in the abdominal cavity can be effectively prevented.

5. The redundant chemotherapy drugs and malignant ascites in the abdominal cavity can be simply and conveniently extracted by the utility model.

Drawings

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of the structure of the infusion tube of the present invention;

in the figure: 1-sealing cover, 2-bottom plate, 3-transfusion tube, 4-fixing hole, 5-cross partition, 6-small transfusion tube and 7-side groove.

Detailed Description

The invention is described in further detail below with reference to the accompanying drawings:

as shown in fig. 1 and 2, the infusion tube comprises a cylindrical sealed hollow chamber formed by fixedly connecting a cylindrical sealing cover 1 and a bottom plate 2, wherein the bottom of the side surface of the sealing cover 1 is provided with an opening, and an infusion tube 3 is fixedly connected to the opening.
