Abstract

The utility model discloses a sucking gun for otolaryngology diagnosis and treatment. The sucking gun for otolaryngology diagnosis and treatment comprises a gun head (1), a gun shell (7) and a gun head dislocation device, wherein the gun head (1) is a disposable gun head, a gun opening part at the front end of the gun shell (7) decreases gradually to form a conical abutting connection head, and the conical abutting connecting head of the gun shell (7) is matched with an abutting connection port of the gun head (1). The gun head dislocation device is composed of a dislocation ring (2), an operation rod (3), a spring (4) and a button (5), and the disposable gun head (1) can be pushed down to a dirt bucket by pressing the button (5). According to the sucking gun for otolaryngology diagnosis and treatment, abutting connection and separation of the gun head (1) can be achieved by one hand, and therefore diagnosis and treatment efficiency and medical safety can be effectively improved.

Description

A kind of otorhinolaryngology diagnosis and treatment suction gun

Technical field

This utility model relates to a kind of otorhinolaryngology diagnosis and treatment suction gun.

Background technology:

Secretions and the hemorrhage sucking head that often uses that otorhinolaryngology outpatient service is at present located in removing nose, pharynx, larynx, external auditory meatus etc.Existing sucking head, substantially by the metal manufacture, directly is connected with negative-pressure pipeline during use, there is no controllable handle, the mucosa and the skin that are prone in use that secretions stops up and locate because of the suction side clear-cut margin scratch nasal cavity of sucking head etc.Existing sucking head is reused after adopting sterilization in addition, therefore when sterilization is not thorough, easily causes the nosocomial infection risk.In addition, existing sucking head needs bimanualness while changing, change trouble, affects out-patient treatment efficiency.

Summary of the invention

The purpose of this utility model is to provide a kind of otorhinolaryngology diagnosis and treatment suction gun, and this suction gun adopts disposable rifle head, uses one hand just can realize the quick-replaceable of rifle head.

The otorhinolaryngology diagnosis and treatment that this utility model provides comprise rifle body and rifle head with suction gun, the rifle body consists of the rifle shell, the front end muzzle of rifle shell part is dwindled gradually and is formed the taper butt joint, in the rifle shell, negative-pressure pipeline is installed, and at the side port of negative-pressure pipeline, on corresponding rifle shell, is processed with a pressing hole; One device that the rifle head is dislocated also is installed on the rifle shell, this device is comprised of dislocation ring, stick, spring and button, the dislocation ring is installed on the root of taper butt joint, one end of spring is fixed on the rifle shell, the other end is connected with stick, stick is positioned at the rifle shell, and an end is connected with the dislocation ring, and the other end stretches out the rifle shell and is connected with button; The rifle head consists of butt end, suction catheter and suction side, and the spill docking port of butt end coordinates with the taper butt joint of rifle shell, the edge circle of suction side.

The rifle head that this utility model adopts is disposable rifle head, by non-toxic plastic blowing, made, be divided into two types of adult and children according to caliber and length, according to suction side, whether bending is divided into straight rifle head and curved rifle head, according to operating position, is divided into nasal cavity sucking head, pharyngeal sucking head and throat's sucking head.When the rifle head is not used, uprightly be inserted in the rifle headstock hole that is similar to test tube rack, docking port upwards, the insertion of rifle shell butt joint when being convenient for changing the rifle head.

Use procedure of the present utility model is: be communicated with the vacuum suction pipeline, one hand-held gun body, its taper butt joint is inserted and is arranged in the docking port of the rifle head on the rifle headstock, suitably firmly, the two is closely cooperated and realize that the rifle body is connected with the air-tightness of rifle head, again another hands immobilized patients can be started to the attraction operation at the positions such as nasal cavity, in operation, with forefinger, refer to that abdomen presses the constant voltage hole repeatedly, can realize the control of appeal.End of operation, with thumb press rear portion button, promote the dislocation ring and disposable rifle head evaded and fallen into waste pail by stick, then changes the rifle head, carries out next operation.

This utility model one hand can complete docking and the disengaging of rifle head, and can avoid the infection risk that may cause because reusing same rifle head, has advantages of efficient, convenience, safe, can effectively improve diagnosis and treatment efficiency and medical safety.

The specific embodiment

As shown in Figure 1, this utility model is comprised of rifle head 1, dislocation ring 2, stick 3, spring 4, button 5, rifle shell 7 and negative tube 8, the front end muzzle part of rifle shell 7 is dwindled gradually and is formed the taper butt joint, negative-pressure pipeline 8 is installed in rifle shell 1, be processed with a constant voltage hole 6 at the side port of negative-pressure pipeline 8 on corresponding rifle shell 7, repeatedly press constant voltage hole 6 with finger, can realize the control of suction pressure.

Dislocation ring 2 is installed on the root of taper butt joint, one end of spring 4 is fixed on rifle shell 7, the other end is connected with stick 3, stick 3 is positioned at rifle shell 7, one ends and is connected with dislocation ring 2, and the other end stretches out rifle shell 7 and is connected with button 5, pressing button 5 can make stick 3 reaches, then drive 2 reaches of dislocation ring and rifle head 1 is turned down, after hands unclamps, stick 3 automatically sets back under the effect of spring 4.

The structure of rifle head 1 as shown in Figure 2 and Figure 3, by suction side 101, suction catheter 102 and butt end 103, formed, the shape of the spill docking port of butt end 103 and taper butt joint coincide, can form air-tightness when the taper butt joint is inserted in docking port coordinates, the edge circle of suction side 101, can avoid the scraping damage to therapentic part during use.Fig. 2 is straight rifle head, and Fig. 3 is curved rifle head.When rifle head 1 is not used, uprightly be inserted in the hole of the rifle headstock 9, upwards, while changing rifle head 1, one hand inserts the taper butt joint of rifle shell 7 in the spill docking port of rifle head 1 docking port, slightly firmly makes it to be seated and can use.
