Abstract
The utility model discloses a kind of single use breathing circuit filter, the filtrate chamber comprising upper shell, lower house and be formed between upper shell and lower house, upper shell top is provided with the top connection with equipment connection, lower house bottom is provided with the lower contact be connected with human body, described upper shell is provided with thief hatch, and on thief hatch, interference fit has a block; Upper enclosure inner wall is provided with the fuisw rib of the distribution in swirl shape.This filter, by arranging the block of interference fit, when airway pressure is excessive, can eject, and to remind doctor to change product, ensure that the safe handling of patient; Be provided with fuisw rib in upper shell, be that the air-flow after equipment enters can pass through uniformly in filter membrane, improve the usable area of filter membrane, the stressed of filter membrane is more balanced.
Description
Technical field
This utility model relates to a kind of single use breathing circuit filter.
Background technology
In operation process, due to the not same sex of patient, how much different secretions is, and the breathing circuit filter that individuals patients uses because moisture and secretions, can increase gas-flow resistance, thus increases airway pressure.Airway pressure is excessive, can produce damage to the pulmonary of patient.
Utility model content
This utility model, in order to overcome the deficiencies in the prior art, provides that a kind of gas-flow resistance is little, the single use breathing circuit filter of use safety.
To achieve these goals, this utility model is by the following technical solutions: a kind of single use breathing circuit filter, the filtrate chamber comprising upper shell, lower house and be formed between upper shell and lower house, upper shell top is provided with the top connection with equipment connection, lower house bottom is provided with the lower contact be connected with human body, described upper shell is provided with thief hatch, and on thief hatch, interference fit has a block; Upper enclosure inner wall is provided with the fuisw rib of the distribution in swirl shape.
Further, described lower cover inwall is provided with the fuisw rib of the distribution in swirl shape.
As preferably, the height of described filtrate chamber is 22cm.
In sum, this utility model has the following advantages: this filter, by arranging the block of interference fit, when airway pressure increases, can eject, and to remind doctor to change product, ensure that the safe handling of patient; At least be provided with fuisw rib in upper shell, be that the air-flow after equipment enters can pass through uniformly in filter membrane, improve the usable area of filter membrane, the stressed of filter membrane is more balanced.
Accompanying drawing explanation
Figure l is structural representation of the present utility model.
Fig. 2 is the structural representation of upper shell of the present utility model.
Detailed description of the invention
In order to make those skilled in the art person better understand this utility model scheme, below in conjunction with the accompanying drawing in this utility model embodiment, clear, complete description is carried out to the technical scheme in this utility model embodiment.
As shown in Figure 1, 2, a kind of single use breathing circuit filter, the filtrate chamber 3 comprising upper shell l, lower house 2 and be formed between upper shell and lower house, filter medium is provided with in filtrate chamber 3, upper shell 1 top is provided with the top connection 11 with equipment connection, lower house bottom is provided with the lower contact 21 be connected with human body, and upper shell is provided with thief hatch 13, and on thief hatch, interference fit has a block 5; Upper shell l inwall is provided with the fuisw rib 14 of the distribution in swirl shape, obviously also lower cover inwall also can be arranged the fuisw rib of the distribution in swirl shape.
Further, the height of described filtrate chamber 3 is set to 22mm by this utility model, and the filtrate chamber under this size can ensure necessary strainability, additionally reduces Package size simultaneously, reduces costs.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of this utility model protection.
