Abstract

The invention provides a respiratory tract lower airway droplet collector, and belongs to the technical field of medical equipment. The respiratory tract lower airway droplet collector comprises a connecting rod, a shell, a collecting membrane, a first ring, a handle, second rings, a piston, a lower limiting block, a lower sealing cover and an upper limiting block, wherein the handle is arranged at the upper end of the connecting rod; the piston is arranged in the middle of the connecting rod; the collecting membrane is arranged at the lower end of the connecting rod; the second rings are respectively arranged on two sides of the upper end of the outer surface of the shell; the lower sealing cover is arranged at the lower end of the outer surface of the shell; and the upper limiting block and the lower limiting block are respectively arranged at the upper end and the lower end of the inner surface of the shell. The respiratory tract lower airway droplet collector has the advantages that the respiratory tract lower airway droplet collector is simple in structure, convenient to use and accurate in collection, and patients do not feel pain and do not have wound. Oral pathogen pollution is avoided, accuracy of an inspection result is guaranteed, owing to a limiting device, medical workers can operate the respiratory tract lower airway droplet collector conveniently, work difficulty is reduced, and operational errors are avoided.

Description

A kind of respiratory tract lower air passage droplet collector

Technical field

The present invention relates to technical field of medical instruments, particularly relate to a kind of respiratory tract lower air passage droplet collector.

Background technology

When patient seek medical advice need to gather respiratory tract lower air passage droplet time, usually adopt swab stick to wipe examination method and gather lower airway droplet, the deficiency of this method is comparatively obvious, and intraoral pathogen very easily pollutes swab stick, causes assay inaccurate, directly affects treatment.Also have other method adopting intubate to extract, the more difficult pathogen collecting respiratory tract lower airway of this method, and misery is larger.Have report to adopt lung puncture sampling to detect abroad, although this method makes assay accurate, can't produce pollution, pain is strong, easily produces wound.

Summary of the invention

The invention provides a kind of respiratory tract lower air passage droplet collector, structure is simple, easy to use, have and gather accurately, the advantages such as patient's no pain, hurtless measure, not by oral pathology mycoplasma contamination, ensure the accuracy of assay, and be provided with stopping means, medical worker can be facilitated to operate, alleviate work difficulty, avoid causing operate miss.

For solving the problems of the technologies described above, the embodiment of the present application provides a kind of respiratory tract lower air passage droplet collector, comprise connecting rod, housing and collection film, also comprise finger ring one, handle, finger ring two, piston, lower position block, lower capping and upper limit position block, the upper end of described connecting rod is provided with handle, middle part is provided with piston, lower end is provided with collection film, the both sides, upper end of described housing outer surface are provided with finger ring two, lower end is provided with lower capping, and the two ends up and down of described shell inner surface are respectively equipped with upper limit position block and lower position block.

As the preferred embodiment of this programme, the bottom surface of described handle is groove structure, and size and housing match, and cell wall is provided with screw thread, and the upper surface of handle is provided with finger ring one.

As the preferred embodiment of this programme, the length of described connecting rod is not more than the entire length of housing, and entirety presents inverted T-shape.

As the preferred embodiment of this programme, the entirety of described housing is " convex " character form structure.

As the preferred embodiment of this programme, described piston is elastomeric material, between upper limit position block and lower position block.

As the preferred embodiment of this programme, the material of described collection film is medical grade rubber material.

The one or more technical schemes provided in the embodiment of the present application, at least have following technique effect or advantage:

Structure is simple, easy to use, has and gathers accurately, the advantages such as patient's no pain, hurtless measure, not by oral pathology mycoplasma contamination, ensure the accuracy of assay, and be provided with stopping means, medical worker can be facilitated to operate, alleviate work difficulty, avoid causing operate miss.

Accompanying drawing explanation

In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is the structural representation of the embodiment of the present application.

In Fig. 1,1, finger ring one, 2, handle, 3, connecting rod, 4, finger ring two, 5, housing, 6, piston, 7, lower position block, 8, lower capping, 9, gather film, 10, upper limit position block.

Detailed description of the invention

In order to better understand technique scheme, below in conjunction with Figure of description and concrete embodiment, technique scheme is described in detail.

As shown in Figure 1, a kind of respiratory tract lower air passage droplet collector, comprise connecting rod 3, housing 5 and gather film 9, also comprise finger ring 1, handle 2, finger ring 24, piston 6, lower position block 7, lower capping 8 and upper limit position block 10, the upper end of described connecting rod 3 is provided with handle 2, middle part is provided with piston 6, lower end is provided with and gathers film 9, the both sides, upper end of described housing 5 outer surface are provided with finger ring 24, lower end is provided with lower capping 8, and the two ends up and down of described housing 5 inner surface are respectively equipped with upper limit position block 10 and lower position block 7.

Wherein, in actual applications, the bottom surface of described handle 2 is groove structure, and size and housing 5 match, and cell wall is provided with screw thread, the upper surface of handle 2 is provided with finger ring 1, both can use as handle, facilitate push-and-pull connecting rod 3, can use as closing cap again, collection film 9 is completely enclosed within housing 5, preventing pollution.

Wherein, in actual applications, the length of described connecting rod 3 is not more than the entire length of housing 5, and entirety presents inverted T-shape, and when not using by connecting rod 3 completely retraction housing 5, both convenient storages, can prevent again gathering film 9 and be polluted.
