Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Example 1

As shown in fig. 1-3, a combined negative pressure sputum collection kit comprises a collection cup 1, a collection cup cover 2, a sputum suction tube 3, a connecting tube 4 and a negative pressure tube 5. Wherein, collect cup 1 and adopt 130mm, diameter 22 mm's centrifuging tube, its outer wall is equipped with the scale, and top opening part is equipped with the external screw thread.

The diameter of the collecting cup cover 2 is about 22mm, and the inner wall of the collecting cup cover is provided with internal threads and is detachably connected with the external threads on the top of the collecting cup 1. The sputum inlet joint 21 and the negative pressure joint 22 penetrate through the collecting cup cover 2, the end parts of the sputum inlet joint and the negative pressure joint, which extend into the collecting cup 1, are extending-in ends, and the end parts of the connecting pipelines are exposed ends. The length of the extending end of the sputum inlet joint 21 is longer than that of the negative pressure joint 22, so that sputum can be prevented from directly entering the negative pressure joint 22 during sputum suction.

Furthermore, the extending end of the sputum inlet joint 21 is a cone-shaped structure with an inner diameter gradually decreasing from top to bottom, so that the flow rate of sputum flowing through the end can be increased, and the sputum is ensured to be sprayed into the collection cup 1. The outlet of the extending end of the negative pressure joint 22 is an inclined plane, and when a plurality of collecting cups 1 are required to be connected in series to collect sputum, the sputum can be guided to flow into the negative pressure joint 22.

The exposed end of the sputum inlet joint 21 can be detachably connected with the sputum suction pipe 3 and the connecting pipe 4 respectively, and the exposed end of the negative pressure joint 22 can be detachably connected with the connecting pipe 4 and the negative pressure pipe 5 respectively, so that one or more collection cups 1 can be used or connected according to actual requirements to obtain one or more sputum samples. The outer sides of the sputum inlet joint 21 and the negative pressure joint 22 are respectively provided with a clamping piece for clamping the pipeline, so that the connection stability of the corresponding pipeline and the joints is improved.

Specifically, the clamping member includes a plurality of jaws 23 arranged in a circular shape, and a locking ring 24 screw-coupled to an outer wall of each jaw 23. The gap between the clamping piece 23 and the sputum inlet joint 21 and the gap between the clamping piece 23 and the negative pressure joint 22 are gradually reduced from bottom to top, and the height of the clamping piece 23 is greater than the height of the exposed ends of the sputum inlet joint 21 and the negative pressure joint 22. When the pipeline is connected, the pipeline is firstly inserted into the gap between the clamping piece 23 and the sputum inlet joint 21 or the negative pressure joint 22, and then the locking ring 24 is rotated upwards to compress the pipeline (the sputum suction pipe 3, the connecting pipe 4 or the negative pressure pipe 5).

The outer walls of the exposed ends of the sputum inlet joint 21 and the negative pressure joint 22 are provided with anti-skid lines, so that the stability of pipeline connection can be further improved. The top of the outer wall of each clip 23 is provided with a limiting protrusion 231 to prevent the lock ring 24 from rotating excessively to fall off. The present invention is also provided with a sealing cap (not shown) screwed to the collection cup 1 to seal and deliver the sample after sampling.

Although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the utility model.
