8. The bag for medical use having three compartments according to claim 1, wherein the first compartment contains a solvent, which allows to prime and install the perfusion line without possibility of contact with a product for cytotoxic treatment.

9. The bag for medical use having three compartments according to claim 1, wherein the third compartment, which contains a solvent, allows to ensure the administration of a complete treatment dose.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present disclosure will be better understood via the following description, made below purely for informational purposes, of an aspect of the present disclosure, in reference to the Drawings in which:

[0021] FIG. 1 illustrates the bag according to the present disclosure, in one aspect; and

[0022] FIG. 2 shows the various steps of the method according to the present disclosure.

DETAILED DESCRIPTION

[0023] The present disclosure relates to a bag 10 for medical use having three compartments 11, 12, 13. This bag 10 comprises a compartment 11 containing a solvent, a compartment 12 containing a solute and a compartment 13 containing a solvent, the compartment 12 containing a solute being separated from the other two compartments 11, 13 by pincers 14, 15, the opening of which allows liquid to flow by gravity.

[0024] During opening of one of said pincers 14, 15 and under the effect of a pressure, the liquid contained in a compartment is propelled towards another compartment.

[0025] FIG. 1 illustrates the bag according to the present disclosure, in one aspect.

[0026] It is observed in FIG. 1 that the bag 10 according to the present disclosure further comprises three filling tubes 16, 17, 18, each of said filling tubes 16, 17, 18 being associated with one of said compartments 11, 12, 13.

[0027] After filling of the compartment by the pharmacist, the tube is welded and cut in order to close off access to the compartment, which secures the preparation of the pharmacist.

[0028] It is also observed in FIG. 1 that the bag 10 according to the present disclosure further comprises an outlet tube 19 for the administration of the treatment to a patient.

[0029] The compartment 11 is used to purge the line. It is impossible to directly use the treatment product, since there would be a risk of contact at the end of the line with the person who implements the present disclosure.

[0030] The solute is released after passage of the solvent. An action on a jib crane is carried out.

[0031] Moreover, the perfusion line is secured by a peristaltic pump, which detects a presence of air if the intervention of the personnel is too late.

[0032] The three compartments 11, 12 and 13 are disposed in such a way as to be able to be administered in the correct order sequentially.

[0033] The first compartment 11 contains a solvent, which allows to prime and install the perfusion line without possibility of contact with the product for cytotoxic treatment.

[0034] This secures the use by the caregiving personnel.

[0035] The third compartment 13 contains a solvent and allows to ensure the administration of the complete treatment dose, which allows to guarantee the taking of the intended dose.

[0036] The disposition of the compartments 11, 12 and 13 allows the creation of the bag on opposite-tube automatic-production machines (contrary to the adjacent faces).

[0037] The separation of the compartments 11, 12, and 13 is carried out by pincers 14, 15, which are in one aspect made of plastic material. These pincers pinch the two films in order to guarantee the impermeability. This leads to a permanent deformation. Upon the opening of one pincer, a pressure is necessary to propel the liquid towards the following compartment. The propelled liquid improves the rinsing of the compartment.

[0038] The present disclosure also relates to a method for use of a bag 10 for medical use having three compartments 11, 12, 13, said method comprising the following steps:

[0039] Purge of a line by means of a liquid contained in a compartment 11 containing a solvent;

[0040] Opening of a pincer 15 separating two compartments 11, 12, in order to release a solute contained in a compartment 12; and

[0041] Opening of a pincer 14 separating two compartments 12, 13, in order to release a solvent contained in a compartment 13.

[0042] The method according to the present disclosure is illustrated in FIG. 2.

[0043] The bag 10 according to the present disclosure is capable of being used in a hospital environment, and also in the home of the patients in the context of home care.

[0044] The present disclosure is described above as an example. It is understood that a person skilled in the art is capable of carrying out various alternatives of the present disclosure without actually going beyond the context of the patent.
