Negative pressure suction head also claims operation suction head, is a kind of medical instrument, is generally single use, can lose after to a patient with operation debridement imbibition.
When carrying out out abdomen or open the operations such as breast, the visual field is stated in order to fully expose hands, often need to absorb patient's internal water accumulation, residual liquid, blood etc., conventional apparatus is negative pressure suction head, negative pressure suction head is connected with negative pressure generator, opens negative pressure generator, produce certain negative pressure, under the draft effect of this negative pressure, the hydrops in patient body, residual liquid, blood etc. are drawn clean by negative pressure suction head.
Because current sucking head is straight shape, cannot arbitrarily bend and extend, straight sucking head be usually difficult to arrive desirable attraction position, causes inconvenient operation.Especially when drawing throat and intrabronchial hydrops, residual liquid, blood, sputum, more obviously.Anaesthetist, when anesthetic intubate, usually needs the secretions such as the sputum drawing lower pharyngeal cavity, is beneficial to clearly expose glottis, inserts anesthetic intubate rapidly.Easily damage the rear wall of throat clinically, cause bleeding.Especially when drawing the sputum of left bronchus, become more difficult.
Utility model content
In view of this, the utility model proposes a kind of negative pressure suction head, to solve the problem that straight sucking head is difficult to arrive desirable attraction position.
On the one hand, this utility model provides a kind of negative pressure suction head, comprise suction catheter, the head end of suction catheter is provided with casing coupling formula joint, the end of suction catheter is provided with imbibing hole, imbibing hole communicates with the tube chamber of suction catheter, and suction catheter at least one section is scalable and random bending telescoping tube, and the outer wall of telescoping tube is undulating pleats.
All can stretch to make suction catheter whole process and arbitrarily bend, further, the whole process of suction catheter is telescoping tube.
Cause telescoping tube distortion to shrivel to prevent breathing air pressure, further, telescoping tube is embedded with spiral type support ring.
In order to prevent suction catheter end from damaging the mucosa in throat, cause bleeding, further, the outer circumferential walls of suction catheter end is spherical structure, and imbibing hole is spaced apart along spherical circumference direction, and the external diameter of spherical structure is greater than suction catheter external diameter.
In order to prevent imbibing hole from directly contacting attraction mucosa with bronchus with the mucosa of throat, mucosa is caused to damage.Further, spherical circumference face offers the groove of annular, and imbibing hole is opened in groove.
In order to doctor can regulate vacuum magnitude automatically, control captivation, further, comprise handle, handle is connected with suction catheter, and handle offers at least one passage, and passage communicates with the tube chamber of suction catheter.
Further, handle is provided with chute, chute is provided with the slide plate for blocking passage, and slide plate can move along chute.
Conveniently operate, further, comprise air bag, air bag is connected with casing coupling formula joint.
In order to make sucking head use as sputum aspirator tube, further, the head end of the suction catheter sealing-plug that is provided with seal and coordinates with seal.
In order to prevent telescoping tube from damaging mucosa, further, also comprise protective sleeve, protective sleeve is enclosed within telescoping tube, and protective sleeve is connected with suction catheter, and protective sleeve outer wall is smooth.
A kind of negative pressure suction head of the present utility model, beneficial effect is: adopt scalable and random bending telescoping tube, solves straight sucking head at present and is difficult to arrive the problem of desirable attraction position, easy to operate, use reliable, the problem that bronchus and bottleneck throat cause bleeding can be prevented.Telescoping tube is embedded with spiral type support ring, can prevent breathing air pressure and cause telescoping tube distortion to shrivel, cause vapour lock, the problem of imbibition difficulty.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining this utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is sucking head structural representation of the present utility model.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in this utility model and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe this utility model in detail in conjunction with the embodiments.
Below in conjunction with Fig. 1, preferably be described in further detail of the present utility model, a kind of negative pressure suction head of this preferred embodiment: comprise suction catheter and handle 2, suction catheter and the integrally formed structure of handle 2, suction catheter is made up of the plastics of medical poisonless, as PVC material or medical polyvinyl material are made.The head end of suction catheter is provided with casing coupling formula joint 1, and casing coupling formula joint 1 is that the outside of tube wall is provided with falling from power of taper, is connected reliably with negative pressure generator or air bag to make casing coupling formula joint 1.The end of suction catheter is provided with imbibing hole 60, imbibing hole 60 is arranged in the end outer circumferential walls of suction catheter, realizes the object of side imbibition.Imbibing hole 60 communicates with the tube chamber of suction catheter.
Can stretch to make suction catheter bribes bending with any side, and suction catheter at least one section is scalable and random bending telescoping tube 4, and the outer wall of telescoping tube 4 is undulating pleats, and it is formed with spirality convex rib.All can stretch to make suction catheter whole process and arbitrarily bend, suction catheter also whole process can be telescoping tube 4.
Cause telescoping tube 4 distortion to shrivel to prevent breathing air pressure, telescoping tube 4 is embedded with spiral type support ring 5, and support ring is made up of metal material.
In order to prevent suction catheter end from damaging the mucosa in throat, cause bleeding, the outer circumferential walls of suction catheter end is spherical 6 structures, and imbibing hole 60 is spaced apart along spherical 6 circumferencial directions, and the external diameter of spherical 6 structures is greater than suction catheter external diameter.
In order to prevent imbibing hole 60 from directly contacting attraction mucosa with bronchus with the mucosa of throat, mucosa is caused to damage.Spherical 6 peripheries offer the groove 61 of annular, and imbibing hole 60 is opened in groove 61.
