Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0016] The anti-block suction device of the present embodiment is as figure 1 As shown, it includes: a suction tube 1 and a negative pressure connector 3 , one end of the suction tube 1 is a suction port 11 , and the other end is connected to a negative pressure connector 3 to form a pipeline from the suction port 11 to the negative pressure connector 3 . The inner diameter of the suction tube 1 gradually increases from one end of the suction port 11 to the other e...

Abstract

The invention relates to the technical field of medical apparatus, and discloses an anti-block aspirator. The anti-block aspirator comprises a suction catheter and a negative pressure joint, wherein asuction opening is formed in one end of the suction catheter, and the other end of the suction catheter is connected with the negative pressure joint; and the inner diameter of the suction catheter is gradually increased from one end of the suction opening to the other end of the suction opening. According to the anti-block aspirator disclosed by the invention, the inner diameter of the suction catheter is gradually increased from one end of the suction opening to the other end of the suction opening, blocking cannot be generated by tissue, skeletal fragments and the like through entering thesuction catheter from the small opening, and anti-block can be realized without adding any anti-block structure, so that the structure is simple and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an anti-blocking suction device. Background technique [0002] The suction device is mainly used to suck out the normal saline, blood, bone debris, tissue, etc. after the surgical site has been washed during the operation. The suction tubes of existing suction devices are all straight hollow tubes, which are prone to clogging in different degrees. In order to prevent tissue debris from clogging the inside of the pipeline, most of the existing anti-clogging suction devices are equipped with anti-clogging structural parts on the pipeline (such as: Blind hole pipe sections or filter screens at the suction end), adding structural parts to the thinner pipes makes the structure of the anti-blocking suction device complex, the production cost is high, and the suction resistance is large, and it cannot effectively suck out bone chips with slightly larger dimensions These sli...
