Definitions
- the present invention relates to a tube joining apparatus used for joining tubes.
- the peritoneal dialysis method uses a tube (catheter) embedded in the abdominal cavity of a patient to put a predetermined dialysate into the body, and then removes water and waste products transferred to the dialysate through the peritoneum. Is the method.
- the tube embedded in the patient is joined in a fluid-tight manner to the tube of the bag containing the dialysate.
- the dialysate is drained from the body, the tube embedded in the patient is joined in a fluid-tight manner to the tube of the drain bag.
- the tube joining device When using the tube joining device described above, a user such as a patient manually sets the tubes to be joined to each other and sets them on the device, and at this time, the tube itself has flexibility. Therefore, the handling of the tube may be wrong, and the tube may be piled up in a twisted state, or three tubes may be piled up. If the apparatus performs the fusing-joining operation with the tube set in this manner, the tubes are joined together, but joining failure such as opening of holes occurs in the joined portion.
- the tube joining device when joining the tubes, the tube joining device once releases the holding (set) of each tube and rotates the tube so that the ends of each tube are replaced. For this reason, it is necessary to provide the tube joining apparatus with a mechanism for automatically releasing the holding of the tube at an appropriate timing. However, if such a mechanism is added, the structure of the apparatus becomes complicated. Concerned.
- the present invention has been made in view of the above problems, can prevent the occurrence of poor bonding due to a tube setting error, and realizes holding and releasing of the tube with a simple device configuration.
- An object of the present invention is to provide a tube joining apparatus.
- the end portion of the first tube and the end portion of the second tube are melted by the heated plate-shaped cutting member, and then the melted end portion of the first tube and the first tube are cut.
- the 1st tube holding part which can hold one tube of the 1st tube and the 2nd tube, and the other tube of the 1st tube and the 2nd tube are held.
- An overlapping portion and a switching mechanism capable of switching between holding the other tube by the second tube holding portion and releasing the holding.
- the switching mechanism applies an urging force for maintaining the state of holding the other tube to the second tube holding portion, and the first tube holding portion and the second tube holding portion. As the lens moves relatively closer, an urging force for maintaining the state in which the other tube is released is applied to the second tube holding portion.
- the user sets each tube individually to the first and second tube holding portions, and performs an operation of moving each tube holding portion relatively closer.
- each tube can be arrange
- the tube can be held and released by a simple device configuration including a switching mechanism.
- FIG. 2A is a diagram illustrating a configuration example of an operation panel unit provided on the front side of the housing illustrated in FIG. 1, and FIG. 2B is provided on an upper surface of the housing illustrated in FIG.
- FIG. 2A shows the structural example of the displayed display part.
- FIG. 5A is a perspective view showing the bottom surface of the wafer cassette, and
- FIG. 5B is a perspective view showing the top surface of the wafer cassette.
- FIGS. 15A to 15D are diagrams schematically showing each process of fusing and joining work by the tube joining apparatus.
- 16A and 16B are diagrams for explaining the tube after joining.
- FIG. 16A is an enlarged view showing each tube after joining
- FIG. 16B is a diagram showing each tube after joining. It is a figure which shows an arrangement
- the tube joining apparatus 1 melts and melts the ends of a plurality of tubes T1 and T2 (hereinafter referred to as the first tube T1 and the second tube T2) and pressurizes the melted ends in a sterile state.
- a dialysate tube (corresponding to the first tube T1) of the peritoneal dialysate bag and a tube (second second) on the peritoneal catheter side of the user M such as a patient used for peritoneal dialysis.
- the tube joining device will be described through an example applied to a medical device used for joining (corresponding to tube T2) (see FIG. 14).
- the tube bonding apparatus 1 melts the end of the first tube T1 and the end of the second tube T2 with a heated wafer WF (corresponding to a plate-like cutting member). Then, the melted end portion of the first tube T1 and the melted end portion of the second tube T2 are replaced and joined.
- a heated wafer WF corresponding to a plate-like cutting member
- the preferable use environment of the tube joining apparatus 1 is, for example, an environmental temperature of 10 to 40 ° C. and a relative humidity of 30 to 85%.
