Description
Technical field
This utility model relates to a kind of detachable suction catheter, belongs to medical surgical instrument field.
Background technology
Suction catheter is one of operating theater instruments the most frequently used in clinical operation, monoblock type and detachable two types can be divided into according to assembling form, the detachable suction catheter of current employing compensate for the sucking head that monoblock type suction catheter exists and can not dismantle, change, cost is high, not easily dredges and the shortcoming such as cleaning.
Because type of surgery is different, require different to the pipe diameter size, camber, length etc. of suction catheter, thus cause the problem that suction catheter specification is various, O&M is loaded down with trivial details, detachable suction catheter, because sucking head is detachable, replacing, be convenient to cleaning and safeguard, a kind of handle can the sucking head of supporting supporting various specifications, use flexibly, purposes is many, improve range of application and the utilization rate of suction catheter, reduce the use cost of suction catheter, compensate for the sucking head that monoblock type suction catheter exists and can not dismantle and change, not easily dredge and the shortcoming such as cleaning.
But, the taper fit adopting routine between the sucking head of existing detachable suction catheter and suction catheter handle more, due to mismachining tolerance, easily cause the problems such as taper fit is bad, contact area is few, poor air-tightness, and sucking head easily gets loose, there is potential safety hazard to a certain degree, in order to improve sealing effectiveness, general employing seal with elastometic washer, but the defects such as rubber ring existence easily damages, service life is short, clean and maintenance trouble.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of simple and reasonable, be easy to processing, the solid and reliable and detachable suction catheter that air-tightness is good.
Detachable suction catheter described in the utility model, comprise sucking head and suction catheter handle, sucking head combines by attracting body and taper joint, taper joint rear end is provided with round taper hole, the hole wall at round taper hole rear portion has closely-pitched female thread, round taper hole described in correspondence, closely-pitched female thread are provided with outer conical surface, closely-pitched external screw thread at the head of suction catheter handle, and the head of suction catheter handle is adopted taper fit with taper joint and is connected by fine thread.
In this utility model, sucking head and suction catheter handle are by adopting taper fit and fine thread locking, and not only solid and reliable, can also play dual sealing functions, air-tightness is good.Owing to adopting technique scheme, overcome current detachable Medical suction tube and install problem that is insecure, poor air-tightness when changing sucking head, being applicable to doctor needs often to change suction catheter sucking head and carries out using in the operation process of the operation such as imbibition, drain.
Preferably, described taper joint and suction catheter handle adopt the taper fit of 1.5 ° ~ 3 °, effectively can increase the contact area of taper joint and the suction catheter handle conical surface therebetween, the sealing of both guarantees link position.
Preferably, described closely-pitched female thread, closely-pitched external thread length are 3 ~ 4 pitch, and suction catheter handle and sucking head are connected by fine thread and realize fixing and locking.
Preferably, when the described outer conical surface of suction catheter negative winding stem and the hole wall of the round taper hole of taper joint are mutually fitted completely and compressed, the length of action of closely-pitched female thread, both closely-pitched external screw threads is 1 ~ 2 pitch.So in use, only need rotation 1 ~ 2 to enclose, just sucking head can be installed, be fixed on suction catheter handle; Use terminate or change sucking head time, reversing 1 ~ 2 circle equally just can easy removal, easy to operate, quick, is convenient to cleaning, safeguards.
The beneficial effect that this utility model is compared with prior art had is:
This detachable suction catheter is simple and reasonable for structure, be easy to processing; By adopting taper fit and fine thread locking, not only solid and reliable, can also play dual sealing functions, air-tightness is good; Only needing rotation 1 ~ 2 to enclose during operation just can be fixed on suction catheter handle by sucking head, easy to operate, quick.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of suction catheter handle;
Fig. 3 is the structural representation of sucking head.
In figure: 1, attract body; 2, taper joint; 3, round taper hole; 4, negative pressure adjustment hole; 5, suction catheter handle; 6, outer conical surface; 7, closely-pitched external screw thread; 8, closely-pitched female thread.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figures 1 to 3, this detachable suction catheter comprises sucking head and suction catheter handle 5, sucking head combines by attracting body 1 and taper joint 2, attraction body 1 can be the gapless stainless steel tube of different-diameter, gapless stainless steel tube is welded on taper joint 2 front end, taper joint 2 rear end is provided with round taper hole 3, the hole wall at round taper hole 3 rear portion has closely-pitched female thread 8, round taper hole 3 described in correspondence, closely-pitched female thread 8 is provided with outer conical surface 6 at the head of suction catheter handle 5, closely-pitched external screw thread 7, the head of suction catheter handle 5 is adopted taper fit with taper joint 2 and is connected by fine thread, suction catheter handle 5 is provided with negative pressure adjustment hole 4.
In this suction catheter, sucking head and suction catheter handle 5 are by adopting taper fit and fine thread locking, and not only solid and reliable, can also play dual sealing functions, air-tightness is good.Owing to adopting technique scheme, overcome current detachable Medical suction tube and install problem that is insecure, poor air-tightness when changing sucking head, being applicable to doctor needs often to change suction catheter sucking head and carries out using in the operation process of the operation such as imbibition, drain.
