Description

Safety negative pressure suction apparatus head

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a safe type negative pressure suction ware head.

Background

The aspirator is used for aspirating and removing the contents of hemorrhage, exudate, pus and thoracic organs in the operation, so that the operation is clear, and the pollution chance is reduced. The principle of the suction apparatus is very simple, namely, the negative pressure state of the suction head is manufactured by a certain method, so that substances outside the suction head can be extruded to the suction head by atmospheric pressure, and the suction effect is achieved.

When the suction apparatus is used in operation, the suction head is placed at the wound to perform negative pressure suction. At present, in order to facilitate the surgeon to freely adjust the magnitude of the negative pressure suction force according to the suction condition, the surgeon usually uses a suction head with a manual control opening for adjustment during the operation, the suction head is arranged on a suction apparatus, and the surgeon presses the opening by the thumb or the index finger to control the negative pressure suction force of the suction head, so that the operation is convenient. However, because the aspirator body is always in a negative pressure working state, even if a doctor does not press the opening, a certain suction force still exists in the aspirator head, and the defects exist: when a doctor needs to take the suction apparatus head away or temporarily block the suction force and then replace the suction apparatus head to other affected parts for suction, the suction apparatus head is adsorbed on the surface of a blood vessel or a nerve, and at the moment, if the suction apparatus body switch is closed to block the suction force in the suction apparatus head, the suction apparatus is very inconvenient and wastes time.

Chinese patent documents: CN201621101053.3, application date 2016.09.30, patent names: an aspirator tip capable of adjusting the suction force. The suction force adjustable aspirator head comprises a hollow tube and a clamping plate sleeved on the hollow tube, wherein a clamping seam is arranged on the clamping plate, a plurality of notches are symmetrically arranged on two sides of the clamping seam, and the notches are arranged in a sequence from deep to shallow; the tail end of the hollow pipe is also provided with a connector. The utility model has simple structure and convenient use.

Chinese patent documents: CN201120382333.7, application date 2011.10.10, patent names: a hand-controlled negative pressure aspirator tip. The hand-controlled negative pressure aspirator head comprises a straight cylindrical body made of plastic, an aspirator sleeve head made of plastic is arranged at the front end of the body, a plurality of controlled negative pressure aspiration holes are formed in the rear section of the body, a conical aspiration nozzle is arranged at the front end of the aspirator sleeve head, an air vent is further arranged on the aspirator sleeve head, and a hole plug capable of being opened and closed is arranged on the air vent.

In the above patent document CN201621101053.3, a clamping plate is disposed on a medical suction apparatus head, and the suction force of the suction apparatus head is adjusted by notches with different depths at the clamping seams of the clamping plate, such as small suction force when sucking effusion between intestinal loops, large suction force when sucking effusion between abdominal cavities, and closed suction force when being used as a poking-out device or a probe, so that the adaptability of the suction apparatus is better; in the manual negative pressure aspirator tip disclosed in patent document CN201120382333.7, a plurality of controlled negative pressure aspirating holes are opened at the rear section of the aspirator tip body, the utility model has a simple structure, good effect of aspirating and removing accumulated fluid and hematocele in the thoracic and abdominal cavities, and avoids injury of organs in thoracic and abdominal cavities caused by negative pressure wall aspiration in operation. However, there is no report on a safety vacuum suction device head which can automatically adjust or completely block the suction force according to the suction requirement, thereby facilitating the replacement suction operation of a plurality of wounds and avoiding damaging the tissue surface.

In view of the above, there is a need for a safety vacuum suction device head that can automatically adjust or completely block suction force according to suction needs, thereby facilitating the replacement of multiple wounds and avoiding damage to tissue surfaces.
