A sleeve includes a body having a top opening. The body covers a handheld oximeter probe or a portion of the probe. The sleeve has a shape that approximately matches the oximeter probe or portion of the probe, which is covered by the sleeve. The sleeve has a top opening that allows a user to slide the oximeter probe into the sleeve. The sleeve is transparent to radiation emitted and collected by the oximeter probe. The sleeve is formed of a material that prevents patient tissue, fluid, viruses, bacteria, and fungus from contacting the covered portions of the oximeter probe. The sleeve leaves the probe relatively sterile after use so that little or no clearing of the probe is required for a subsequent use, such as when the probe is covered with a new, unused sleeve.

The invention discloses a push-pull type sterile cell brush provided with a replaceable brush head for an endoscope. The push-pull type sterile cell brush comprises a drainage tube, the brush head, a push-puller and a traction fiber, wherein the brush head is connected to the head of the drainage tube in a detachable way; a cell brush is arranged in the brush head; an opening is formed in the end, far away from the drainage tube, of the brush head; the traction fiber penetrates into the drainage tube, one end of the traction fiber is connected with the cell brush in a detachable way, and the other end of the traction fiber is connected with the push-puller; the cell brush is externally provided with a protective film; the head of the protective film is connected with the brush head, and the tail of the protective film is connected with the tail of the cell brush. The internal cell brush can be used for brushing bacteria living specimens and / or cell samples of an intestinal mucosal surface layer in a living intestinal cavity wall under the condition of being in conjunction with the drainage tube and the push-puller; furthermore, with the protection of the protective film, bacteria / cell brush pollution caused by the pollution to a channel of endoscopic biopsy forceps can be avoided. After the push-pull type sterile cell brush is used, the sterile cell brush head can be replaced, so that the cell brush can be repeatedly used in a germ-free condition; therefore, the collection credibility of samples of all intestinal tract parts can be maintained to the utmost extent while the cost is lowered.

Disclosed are a separation type intelligent refrigeration freshness retaining machine and a refrigeration freshness retaining method thereof. The separation type intelligent refrigeration freshness retaining machine comprises a cylindrical container used for containing protoplasmic beer, wherein the cylindrical container comprises an inner shell and an outer shell wound on the outer portion of the inner shell in a sleeving mode, a gap is kept between the inner wall of the outer shell and the inner shell, a first through hole and a second through hole are formed in the wall of the outer shell, the protoplasmic beer is stored in the inner shell, an interlayer for refrigeration is wound on the outer wall of the inner shell, the interlayer for refrigeration is communicated with one end of a first metal pipe and one end of a second metal pipe, and one end of the first metal pipe and one end of the second metal pipe are in the gap. According to the device, the defects that in the prior art, when a container which is formed integrally and contains the protoplasmic beer is inconveniently cleaned and maintained, in addition, the cleaning effect is poor, and the germ free condition cannot be ensured. In addition, the machine is combined with the refrigeration freshness retaining method of the machine, the temperature and pressure can be stably and efficiently controlled.
