Description

Multipurpose suction unit

Technical field

The utility model relates to medical instruments field, in particular to a kind of multipurpose suction unit.

Background technique

Currently, needing usually to need repeatedly to puncture inpatient according to the state of an illness, with row drug therapy or pumping It takes body fluid to judge the state of an illness, however repeatedly punctures the pain and fear that will cause patient, increase and puncture bring infection risk.

In order to reduce puncture bring damage, remaining needle can be usually stamped so that subsequent infusion or blood drawing are used: such as dynamic Vein is for blood gas analysis, and venous detaining needle is for use of being infused or transfuse blood, although the appearance of remaining needle is brought to patient Very big welfare, but the accessory not matched therewith preferably.

When clinically taking out big measurement Pleural effusions or rinsing body cavity, due to not preferable draw-out device, often need repeatedly Aspirator is detached from syringe needle, to empty or extract liquid, syringe needle that aspirator is inserted into or is detached from so repeatedly is increased The risk of syringe needle displacement, and increase corresponding operation time

Utility model content

The main purpose of the utility model is to propose a kind of multipurpose suction unit, it is intended to realize the feelings for not increasing point of puncture Under condition, be infused user or extract gymnastics make.

In addition, if relating to the description of " first ", " second " etc. in the utility model embodiment, " first ", " the Two " etc. description is used for description purposes only, and is not understood to indicate or imply its relative importance or is implicitly indicated meaning The quantity of the technical characteristic shown." first " is defined as a result, the feature of " second " can explicitly or implicitly include at least one A this feature.It in addition, the technical solution between each embodiment can be combined with each other, but must be with ordinary skill Based on personnel can be realized, this technical side will be understood that when the combination of technical solution appearance is conflicting or cannot achieve The combination of case is not present, also not within the protection scope of the requires of the utility model.

The utility model proposes a kind of multipurpose suction units.

Incorporated by reference to referring to Figures 1 and 2, the multipurpose suction unit that the present embodiment proposes includes cylinder 1, core bar 2 and piston 3。

Cylinder 1 can be used transparent plastic and be made, and outer surface has scale.Its cylinder 1 have cylinder bottom 11, barrel 12 and The cylinder lumen 13 being enclosed by cylinder bottom 11 and barrel 12, cylinder bottom 11 has a fluid guidance port 111, from 111 direction of fluid guidance port 13 side of cylinder lumen is extended with an insertion pipe 14, which can be integrally formed injection molding with cylinder 1 and be made.And insertion pipe 14 side wall offers a connecting hole 141.

2 both ends of core bar are with opening and inside has bore passages 21, and bore passages 21 are connected to the both ends open of core bar 2, Core bar 2 can also be used transparent plastic and be made.

Piston 3 is set in the cylinder lumen 13, and piston 3 is generally made of elastic rubber, and piston 3 is fixed on core bar 2 One end simultaneously blocks the open at one end of core bar 2, which is also provided with the resilient channels 31 extended along piston axial direction, such as A tiny hole or tiny slot can be opened up along the axial direction of piston 3, not by when supporting crowded outside be in spontaneous contracting Closed state, and will be softened by when supporting crowded outside.Wherein, it when pushing the core bar 2 keeps piston 3 mobile towards 14 direction of insertion pipe, inserts Adapter tube 14 is inserted into and struts the resilient channels 31 to enter core bar bore passages 21 and be connected to core bar bore passages 21, and the work Plug 3 is stifled to close the connecting hole 141, which is strutted by grafting tubular elastic；The pull-up core bar 2 makes piston 3 towards away from grafting When the movement of 14 direction of pipe is so that piston 3 is detached from the insertion pipe 14, which is closed, and fluid guidance port 111 passes through company Hole 141 is connect to be connected to the cylinder lumen 13 of piston 3 towards 14 side of insertion pipe.In order to enable insertion pipe 14 is more easily inserted simultaneously The resilient channels 31 are strutted, one end of insertion pipe 14 towards the piston 3 can be made into spine shape.

As described above, when insertion pipe 14 is inserted into and struts the resilient channels 31 to enter core bar bore passages 21 and and core bar After bore passages 21 are connected to, core bar 2 and insertion pipe 14 just form a perforative access, can deviate from insertion pipe in core bar 2 14 open at one end connects perfusion tube, and works as infusion in the fluid guidance port 111 at 1 bottom of cylinder connection remaining needle to be patient fluid infusion When needing blood test after the completion, directly piston 3 can be made to progressively disengage the insertion pipe 14,14 side of insertion pipe by the pull-up core bar 2 The connecting hole 141 of wall is no longer closed by piston 3 is stifled, such as Fig. 1, at this point, the cylinder lumen 13 of 3 lower section of piston is with respect to the fluid guidance port 111 Place forms negative pressure, and the body fluid B (such as blood) of patient will be pumped in the cylinder lumen 13 to chemically examine and to use, such as through connecting hole 141 This, need to only puncture a point of puncture on a patient body can be realized two operations of infusion and blood drawing, puncture so as to reduce Number is damaged with reducing to patient's bring.

In addition, in order to push and pull the convenience of the core bar 2, such as Fig. 3, it can be convex in outside wall surface of the core bar remote 2 from 3 one end of piston If a round boss 4 being integrally formed with core bar as grip part to use.

Furthermore it is also possible to be connected between the barrel of 1 open end of grip part and cylinder by rubber membrane 5, with sealed cylinder Open end, so that bacterium and dust be avoided to enter in cylinder lumen.

When the multipurpose suction unit of the utility model carries out Pleural effusions extraction, the blood drawing shown with above-described embodiment is former It manages essentially identical.Such as Fig. 3, make outlet of the core bar 2 far from one end of insertion pipe 14 in closed state.It can be in the connection of insertion pipe 14 141 one end of hole connects two and all has two extension tubes that folder closes device, is extension tube 6A and extension tube 6B respectively, it then opens and prolongs The folder of long tube 6A, which closes device and closes the folder of extension tube 6B, closes device, after ascites is drawn into the cylinder lumen of 3 lower section of piston, then closes The folder for closing extension tube 6A, which closes device and opens the folder of extension tube 6B, closes device, then ascites is passed through extension tube 6B dispatch to predetermined container It is interior.The extension folder that first opening extend into flushing liquor after connecting device if if the flushing in an actor's rendering of an operatic tune road closes device closing and protrudes into The extension pipe clamp of body cavity closes device with suction irrigation liquid, and then inverse operation can after suction

The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model, It is all under the inventive concept of the utility model, equivalent structure made based on the specification and figures of the utility model becomes It changes, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
