Embodiment 16

[0089] A sixteenth physiotherapy instrument for human body facet joint inflammation is as shown in FIG. 25, and includes a rigid therapy cavity 1, an air passage 18 and a positive-negative pressure generation control system 2. The positive-negative pressure generation control system 2 is connected to the therapy cavity 1 by means of the air passage 18. The therapy cavity 1 is provided with an air nozzle 19 butt-jointed with the air passage 18 of the positive-negative pressure generation control system 2. The rigid therapy cavity 1 is formed by butt-jointing two parts fitted with each other, namely a first therapy cavity 1-1 and a second therapy cavity 1-2. A seam is formed between the first therapy cavity 1-1 and the second therapy cavity 1-2. A gap at the butt joint is sealed by a sealing strip. The first therapy cavity 1-1 and the second therapy cavity 1-2 are fixed by a fastener 5. One end of the therapy cavity 1 is provided with a therapy cavity opening 3, and the therapy cavity opening is openable. The therapy cavity 1 and a limb are sealed by a filling block 6 and a sealing sleeve 20. The filling block 6 is configured to reduce the gap between the limb and the therapy cavity 1. The sealing sleeve 20 is made of an airtight flexible polymer material. The sealing sleeve 20 is seamless and internally hollow. The sealing sleeve 20 has two open ends. The limb is allowed to stretch in or out of the internal hollow. One end of the sealing sleeve 20 is connected to the limb by means of a winding tape 4, and the other end is connected to the therapy cavity opening 3.

[0090] During operation, the seamless sealing sleeve (which is hollow-shaped like an armband or a kneecap) made of a polymer material is integrally sleeved over a limb, and then the therapy cavity is wrapped outside the limb (upper limb or lower limb) needing to be treated. Meanwhile, according to the size of a gap between the limb and the therapy cavity opening, the filling block that is easily replaceable and has a suitable size is used for filling to reduce the gap. The filling block is usually formed by two semicircular rings fitted around the limb to make the sealing more effective. A sealing strip is provided at a seam of various components of the therapy cavity. After installation is completed, various components of the therapy cavity are fixed by a buckle or a strap between the various components of the therapy cavity. Finally, one end of the sealing sleeve is sleeved into the therapy cavity opening while the other end is located on the limb. Thus, the outside atmosphere is isolated from the internal air of the therapy cavity to form a seal. In order to prevent the sealing sleeve from falling off under positive and negative pressures, the sealing sleeve may be fixed to the limb and the therapy cavity by the strap at two ends of the sealing sleeve. In order to ensure a better sealing effect, the sealing sleeve is made of an airtight polymer material having certain elasticity. After the sealing sleeve is connected to the therapy cavity, in order to ensure that the sealing sleeve is firm and does not fall off during operation, the sealing sleeve is fixed to the limb and the opening of the therapy cavity by a fixing rope or a strap.
