The suction bottle 22 can be sealed by fitting.

The suction bag 21 can be filled with, for example, a water absorbent resin 39. This water-absorbent resin (SAP) 39 replaces pulp or water-absorbing paper with a remarkable water absorption power of several hundred times to 1,000 times its own weight and a strong water retention ability that once absorbed liquid does not separate even if some pressure is applied. It is a water absorbing material.

This water-absorbing resin was first synthesized at the Northern Research Laboratory of the United States Department of Agriculture in 1974, but the world's first commercial production was started in Japan (Sanyo Chemical Industry Co., Ltd.) in 1978. Initially, it was used as an absorbent for sanitary napkins. However, in 1982, practical use began as an absorbent for children's paper diapers. Utilization of such functions of the water-absorbent resin 39 as the water-absorbing / water-holding power, swelling power, gelling power, water-absorbing / desorbing properties, and viscosity increasing is under study. Recently, the use of a water-containing gel in which water is absorbed by the water-absorbent resin 39 has also been attempted, and a cooling agent, a gel-like fragrance,
This is an interesting example of artificial snow.

The water-absorbent resin 39 is, for example, a powdery “Sunwet IM-1000” manufactured by Sanyo Chemical Industries, Ltd.
By using (crosslinked product of starch-sodium acrylate copolymer) or “Sunwet IM-5000D” (72 mol% neutralized product of crosslinked polyacrylic acid), the water absorption capacity is 40 to 70 g / g. can get.

Further, a bactericide or a sterilizing agent such as chlorhexidine or a polymethylenebiguanidine organic acid salt compound is polymerized or fixed on the surface of the particles of the water-absorbent resin to the water-absorbent resin 39, so that fungi contained in the aspirated material are removed. It can sterilize or sterilize viruses. In addition,
As the water absorbing agent, a powdery compound containing a salt or oxide made of an amphoteric metal weak acid, an unsaturated carboxylic acid and a highly water-absorbing resin as shown in JP-A-05-007616 can be used.

When the water-absorbing resin 39 mixed with such a bactericide or a sterilizing agent is put into the suction bag 21,
When an aspirated substance such as a body fluid in a body cavity is sucked, the aspirated substance is absorbed into water and solidified into a gel. Sterilization can be performed to reduce or eliminate infectivity. Thereby, the safety of handling the suction bag 21 can be improved.
By making the powdery water-absorbent resin 39 into a fibrous form, it is possible to place the powdery water-absorbent resin 39 on the bottom of the suction bag 21 in advance without being sucked by the suction force from the suction pump 25.
