Abstract
The utility model relates to a negative pressure drainage device, belonging to the field of medical appliances, which comprises a collapsible negative pressure bottle, a spring, and a latex sleeve. The negative pressure drainage device is characterized in that the negative pressure bottle has a bottle body with a collapsible structure, the spring is arranged inside the bottle body, and the latex sleeve blocks a vent hole. The negative pressure drainage device has the advantages of easy air discharge, large suction volume, and convenience for carrying.
Description
Technical field
This utility model relates to the category of medical apparatus and instruments, is a kind of depression drainage device.
Background technology
Existing manual negative pressure drainage device is common negative pressure bottle and collapsible negtive-pressure implement.The advantage of negative pressure bottle is easy to carry, exhaust and convenient, shortcoming be the liquid that sucks after each aerofluxus seldom, do not have the spring force deficiency.And collapsible negtive-pressure implement has the advantage that an aerofluxus can suck liquid in a large number, but carries inconvenience, exhaust problem particularly, each aerofluxus He Guangai that will uncap.
The utility model content
The purpose of this utility model is to provide a kind of improved depression drainage device, and it has easy aerofluxus and the big characteristics of suction volume.
The purpose of this utility model is achieved in that depression drainage device makes collapsible bottle, in spring is arranged.Bottleneck has individual steam vent, and steam vent is sealed by rubber finger sleeve, compression during bottle rubber finger sleeve open gas and discharge from steam vent, arranged the automatic closed grate hole of rubber finger sleeve behind the gas.Because bottle is collapsible, spring is arranged as power again, so once compression is almost all got rid of the gas in the bottle.Therefore, this improved collapsible negtive-pressure implement has the big characteristics of easy aerofluxus suction volume.Be easy to carry.
This utility model only needs to have now negative pressure bottle and changes into collapsiblely, puts into a spring in the bottle, and technology is simple to be implemented easily.But that the depression drainage device after improving has is portable, exhaust and convenient, advantage that suction volume is big.
Description of drawings
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the profile according to the depression drainage device that the utility model proposes.
The specific embodiment
Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.
Depression drainage device comprises a collapsible bottle of main body (1), and a spring (2) is arranged in the main body, and bottleneck has a steam vent (3).
As Fig. 1 is example, compression bottle (1) during use, and gas opens rubber finger sleeve (4) and discharges from steam vent (3).Arranged behind the gas rubber finger sleeve (4) closed grate hole (3) automatically.Spring (3) rises by the bottle (1) of compression as power and produces negative pressure greatly, suck the liquid of drain.
Claims (2)
1. depression drainage device of being made up of negative pressure bottle, spring, rubber finger sleeve, the bottle that it is characterized in that negative pressure bottle is a collapsible negative pressure bottle (1), in the bottle spring (2) is arranged.
2. depression drainage device according to claim 1, its feature are the rarest steam vents of bottleneck (3) of collapsible negative pressure bottle (1), and rubber finger sleeve (4) is with its sealing.
