Abstract
The utility model relates to a medical disposable suction apparatus head capable of preventing obstruction. The utility model is composed of a hollow cylindrical tube body made of transparent plastic material. The front part of a suction tube is provided with a spindle-shaped expanding tube core so that the phenomena that the suction tube and the suction head are obstructed can be effectively prevented. The preferred embodiment is that the front end head of the expanding tube is bent corresponding to the cylindrical tube body so that convenience is brought to medical operation and the visual field of the operator is not blocked.
Description
This utility model belongs to medical instruments field, relates generally in a kind of clinical treatment operation medical negative pressure suction device suction nozzle that attracts aqueous material in the body.
Being used at present the suction catheter of vacuum suction and mucosa that suction nozzle is usually come off, muscle, bone slag etc. in the clinical treatment operation organizes fragment and sludged blood to stop up, generally meet this situation just must disclose bar and insert suction nozzle with the cleaning tamper with a ferrum, if be difficult to tamper is cleaned out for the moment, just have to change again suction catheter and suction nozzle, so phenomenon has been brought many unnecessary troubles and has been prolonged operating time to clinical.
The purpose of this utility model is at the existing in prior technology weak point, provide a kind of rational in infrastructure, be convenient to medical care precess, can prevent suction catheter and the blocked anti-blocking suction pump suction nozzle of disposable medical of suction nozzle effectively.
The purpose of this utility model is to realize by following technical solution: the anti-blocking suction pump suction nozzle of this disposable medical is made of a hollow circuit cylinder body made from transparent plastic material, has the stilbiform of spinning in the front portion of this root body and expands tube core.In the clinical manipulation, when liquid and piece of tissue are inhaled into suction pipe when expanding the tube core place, scatter immediately or form eddy current, make frangible very fast cracked the diminishing of organizing, wherein heavier piece of tissue gravitate is deposited on expanding of tube core and locates the bottom, so also just can prevent the phenomenon of piece of tissue obstruction suction catheter and suction nozzle effectively.During concrete enforcement, can make and expand the front end of tube core and form the bending of certain angle with respect to the hollow cylindrical tube body axis, the purpose of making is suction nozzle to be attracted effectively and the visual field that do not stop operator under tilt condition like this.
Suction nozzle described in the utility model is made with transparent plastic, and cost is low, be convenient to operator observes the character that is attracted thing.Suction nozzle needn't carry out disinfection during use through sterilization treatment and fungi-proofing packing again in the production process, and safety asepsis is convenient and reliable.
Below with reference to accompanying drawing embodiment of the present utility model is illustrated.
Fig. 1 is the structural representation with suction nozzle of bending section tube core.
Fig. 2 is the structural representation of straight pipe body shape suction nozzle.
In device shown in Figure 1, to spin stilbiform and expand tube core 2 and be located at the front portion of hollow circuit cylinder body, it is 7.5～2:1 with respect to the diameter ratio in aperture, two ends that portion's (thickness) diameter is expanded in the midfield of tube core 2.The front end of tube core 2 has a bending with respect to cylindrical tube, and its bending angle is between 15～60 °.Be provided with one at the rear portion of body and accuse decompression adjustment hole 3.
In device shown in Figure 2, the tube core 2 that expands is coaxial setting with cylindrical tube, is distributed with 6～10 side draught holes 5 on tube core 2 anterior walls.
Number in the figure 1 is a suction nozzle body prosopyle; The 4th, be used for the afterbody of the suction nozzle ramped shaped that is connected with suction catheter.
Claims (3)
1, the anti-blocking suction pump suction nozzle of disposable medical, constitute by a hollow cylindrical tube pipe made from transparent plastic material, the front portion that it is characterized in that described hollow circuit cylinder body has the stilbiform of spinning and expands tube core (2), and the midriff of tube core (2) is 7.5～2: 1 with respect to the diameter ratio in aperture, two ends; Be provided with one at the rear portion of body and accuse decompression adjustment hole (3).
2, as the anti-blocking suction pump suction nozzle of disposable medical of claim 1 regulation, it is characterized in that the described front end that expands tube core (2) has a bending with respect to cylindrical tube, its bending angle is between 15～60 °.
3, as the anti-blocking suction pump suction nozzle of disposable medical of claim 1 regulation, it is characterized in that the described tube core (2) that expands is coaxial setting with cylindrical tube, on the anterior wall of tube core (2), be distributed with 6～10 side draught holes (5).
