The present application provides a sample collecting device and a sample collecting apparatus. The sample collecting device includes a housing assembly with a cavity and a filtering unit disposed in the cavity, where the housing assembly is provided with a collecting hole and a suction hole, both of which are communicated with the cavity, the suction hole is communicated with the collecting hole through the filtering unit, the housing assembly is provided with a gateway on its side wall, and at least part of the filtering unit is configured to be moved to an outside of the housing assembly through the gateway. The present application can greatly improve efficiency of sample collection and effectively save the time of medical workers.

Sample collecting device and sample collecting apparatus

A traction apparatus, comprising a clip portion () and a traction portion (), the traction portion containing a closed traction structure (); the closed traction structure being made from an elastic material; the clip portion comprising a main clip body () and a clip arm (); the main clip body being capable of passing through a biopsy channel () of an endoscope (), the clip arm being capable of clip the closed traction structure. Also disclosed is a traction ring used for the traction apparatus, the traction ring being a single closed traction structure or being formed by connecting several closed traction structures, the traction ring being made from an elastic material.

Traction apparatus and traction ring for traction apparatus

An endoscope end cap, including a sleeve member, protrusion elements, and a movable sleeve. The sleeve member is connected to the front end of an endoscope, the sleeve member, the protrusion elements, and the movable sleeve are connected in sequence, and the movable sleeve can move freely on the outer surface of the endoscope. When the endoscope is inserted for examination, the end cap is easy to enter and does not scratch the digestive tract since the end cap has a cylinder-like structure which is smooth and has no angularity; when the endoscope is being withdrawn, the movable sleeve moves distally and abuts against the sleeve member, so as to support the protrusion elements to enable the protrusion elements to dilate the inner wall of the intestine, improving the quality of single endoscope examination, and reducing discomfort of a patient, operation risk, and operation time.

Endoscope end cap

The disclosure provides a cleaning brush configured to clean a working channel of the endoscope. The cleaning brush comprises a first joint, a second joint and a plurality of cleaning units, the plurality of cleaning units are sequentially connected, each cleaning unit comprises a cleaning portion configured to be in contact with the working channel of the endoscope, and the hardness of the cleaning portions of at least two cleaning units in the plurality of cleaning units is different. The first joint and the second joint are respectively connected with two outermost cleaning units in the plurality of cleaning units, and the first joint and the second joint are configured to be connected to make a ring-shaped cleaning brush. The cleaning brush is efficient in removing bioburden from the working channel of an endoscope.

Cleaning brush

A composite phase change material and the method for forming the material is disclosed herein. Thereof, especially a composite phase change material for lithium battery cooling, comprising polyethylene glycol, silica vehicle and composite flame retardant comprising graphite and polymer, wherein the weight ratio of the graphite and polymer is approximately 1:2. The composite phase change material according to the invention has a good stability and a thermal conductivity, a small corrosivity, a high phase transition enthalpy of 150-350 J/g, and a morphological stability during phase change. Moreover, addition of high thermal conductivity material and composite flame retardant ensures good thermal conductivity and excellent flame retardant effect of the phase change material.

Composite phase change material

Battery pack

The present invention provides a level having a body which has a first end, a second end opposed to the first end, and a plane surface which connects the first and second ends, at least one level indicating device mounted to the body, and two end caps which are mounted onto the first and second ends, respectively. Each end cap has an outer end which is distributed by a plurality of resilient portions with small surface area for absorbing impact if the level is accidentally dropped or impacted.
