Abstract
The utility model discloses a silicone corrugated tube which is used for an aeration mask. The utility model comprises a mask connector (1), a corrugated tube body (2) and a flexible tube connector (3), which are combined from left to right. The corrugated tube body (2) is an elastic body which can be bent in all directions, the inner wall (4) of the corrugated tube body shows uneven wall thickness as well as a thick and thin wave arrangement, thereby adding rigidity, preventing an internal cavity from being blocked when the corrugated tube is bent to further be twisted and folded, ensuring smooth aeration of the aeration mask, and being adaptable for clinical application.
Description
Technical field:
This utility model relates to medical apparatus and instruments.Be specifically related to a kind of silica gel corrugated tube that is used for Ventilation mask.
Background technology:
The silica gel corrugated tube is a kind of multiduty connection tube, when it is used for clinical no-wound mechanical ventilation, as a part of Ventilation mask.At present, no-wound mechanical ventilation is important means and the effective measures that all types of respiratory failures are rescued.When Ventilation mask makes being connected of respirator and human respiratory tract, need to keep airtight, be to guarantee effective ventilation and improve anoxybiotic key.Thereby the performance of Ventilation mask and the quality of fixing means have appreciable impact to the effectiveness of the no-wound mechanical ventilation implemented.The silica gel corrugated tube is the connector between Ventilation mask and respirator, because of the silica gel corrugated tube has the characteristic of any bending, has shown its superiority as the connection between the medical apparatus and instruments (equipment), and purposes is wide, easy to connect.But, more existing silica gel corrugated tubes in use, when Ventilation mask with after respirator is connected, because the characteristic of its any bending, in misoperation or when not noticing that patient is dynamic, the distortion that corrugated tube may take place is folding, causes tube cavity to stop up and causes the situation of hypoventilation, has greatly influenced clinical therapeutic efficacy.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned weak point, a kind of silica gel corrugated tube is provided, make it after being used for Ventilation mask and respirator is connected, the folding phenomenon of corrugated tube distortion can not take place in the operation, make to keep the unimpeded of gas passage between Ventilation mask and the respirator.
For achieving the above object, the technical scheme taked of this utility model is:
In original bellows structure, the inboard wall of tube body thickness of corrugated tube is uniformly, thereby makes bellows body softer, has also just brought corrugated tube to be twisted the folding situation of flattening of causing easily.In addition, the inboard wall of tube body thickness of corrugated tube is uniformly, also is difficult for the demoulding when making, and has influenced production efficiency.This utility model has improved the uniform thickness of corrugated tube inboard wall of tube body, designed the uneven thickness layout of silica gel corrugated tube inwall, this uneven thickness layout, make corrugated tube inwall wall thickness be the alternate waveform arrangement of thickness, thereby increased the rigidity of corrugated tube, not only kept the free bend characteristic of corrugated tube, simultaneously, because corrugated tube increased after the rigidity, tube wall produces folding and inner chamber is stopped up in the time of preventing bending, can prevent that also external force is with the bellows body distortion and inner chamber is stopped up; It is inhomogeneous that wall thickness is, and it is poor to have reduced internal diameter of the pipeline, made things convenient for to add taking off of man-hour and touch, and improved work efficiency; Also, reduced the air resistance of pipeline, improved ventilation efficiency because of these characteristics.
This utility model provides a kind of silica gel corrugated tube, and by the face shield joint, bellows body and hose coupling are formed, and they fuse from left to right.This utility model corrugated tube is a part of Ventilation mask.It has two joints, and face shield joint 1 is used for being connected with the face shield shell of Ventilation mask, and hose coupling 3 is used to connect respirator, is the interface channel of respirator and multi-functional Ventilation mask.
The bellows body 2 of described silica gel corrugated tube is an elastomer, can be to all directions bending, its inwall 4 is uneven wall thickness, wall thickness is the alternate waveform of thickness and arranges, increased the rigidity of corrugated tube, tube wall produces and folds and inner chamber is stopped up in the time of preventing bending, also can prevent from because of external force inner chamber to be stopped up in the bellows body distortion.
The beneficial effects of the utility model are to have improved after the thickness of silica gel corrugated tube inboard wall of tube body, be uneven wall thickness, strengthened the rigidity of its body, not can because of Ventilation mask affect the influence be distorted folding, unobstructed, the generation that prevents clogging that have also just kept inner chamber, reduce the air resistance of pipeline, improved the application of clinical no-wound mechanical ventilation effectively.Because inwall is uneven wall thickness, the easy demoulding is beneficial to large-scale production during making, and bigger use value and social benefit are arranged.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings:
Fig. 1 is the cutaway view of this utility model silica gel corrugated tube.
The specific embodiment:
Silica gel corrugated tube of the present utility model shown in Figure 1 comprises face shield joint 1, bellows body 2 and hose coupling 3, and they fuse from left to right, and the face shield shell of described face shield joint 1 and Ventilation mask is connected, and described hose coupling 3 is used to connect respirator.Bellows body 2 is elastomers, can be to all directions bending, its inwall 4 is uneven wall thickness, because wall thickness is inhomogeneous, wall thickness is the alternate waveform of thickness to be arranged, and has increased the rigidity of corrugated tube, and tube wall produces to twist and folds and inner chamber is stopped up in the time of preventing the corrugated tube bending, reduced the air resistance of pipeline, easy demoulding during making.
Claims (3)
1. a silica gel corrugated tube comprises face shield joint (1), bellows body (2) and hose coupling (3) composition, and they fuse from left to right, it is characterized in that the inwall (4) of bellows body (2) is uneven wall thickness.
2. a kind of silica gel corrugated tube according to claim 1 is characterized in that described face shield joint (1) is used for being connected with the face shield shell of Ventilation mask; Hose coupling (3) is used to connect respirator.
