Fig. 3 is the right view for the endocrine effusion sampler that embodiment provides；

In above each figure, 1, sampler barrel；2, hose is sampled；3, sampling probe；4, triple valve；5, drawing liquid chamber；6, T shape is oriented to Slot；7, U-shaped push rod；8, T shape guide pad；9, push handle；10, it pushes pin rubber.

Specific embodiment

It is with reference to the accompanying drawing and real in order to be more clearly understood that the above objects, features, and advantages of the utility model Example is applied to be described further the utility model.It should be noted that in the absence of conflict, embodiments herein and reality The feature applied in example can be combined with each other.For sake of convenience, hereafter such as there are "upper", "lower", "left", "right" printed words, only indicate It is consistent with the upper and lower, left and right direction of attached drawing itself, restriction effect is not played to structure.

Many details are explained in the following description in order to fully understand the utility model, still, this is practical Novel to be implemented using other modes described herein are different from, therefore, the utility model is not limited to be described below The limitation of the specific embodiment of specification.

Embodiment, as shown in Figure 1, Figure 2 and Figure 3, endocrine effusion sampler provided by the utility model, including successively connect Sampler barrel 1, sampling hose 2 and the sampling probe 3 connect, the side of sampler barrel 1 are provided with volume scale, and sampling hose 2 is close to sampling One end of cylinder 1 is provided with triple valve 4, and above-mentioned sampling hose 2, sampling probe 3 and triple valve 4 are the prior art, this is practical new The emphasis of type is the improvement provided 1 drawing liquid form of sampler barrel, is adjusted to the structure of sampler barrel 1, while additionally providing one Kind is convenient for the structure pushed pin.

In order to facilitate drawing liquid, the utility model will sampler barrel be in the prior art that monotubular form is changed to more combining forms, And straight-bar pull form U-shaped push rod will be improved to by the form that pushes away in the prior art, it include 3 in the inside of sampler barrel 1 specifically A equally distributed drawing liquid chamber 5 is evenly arranged with 3 T shape guide grooves 6 on sampler barrel 1, is provided with piston in drawing liquid chamber 5, living The tail portion of plug is provided with U-shaped push rod 7, and the T shape guide pad 8 cooperated with T shape guide groove 6, U-shaped push rod 7 are provided on U-shaped push rod 7 One end be provided with push handle 9；One hand holds sampler barrel 1, with thumb to operator's direction by push handle, U-shaped push rod 7 to The mobile negative pressure that formed of operator's direction carries out drawing liquid.On the one hand, the volume of each drawing liquid chamber 5 in the present apparatus is smaller than 50ml, that is, it is thicker be it is thin, it is more for tailing off, and reduces the power of drawing liquid applied；On the other hand, U-shaped push rod 7 can be in list It can be completed under hand state, it is easy to operate and fool proof.

Further, in order to reduce by the resistance for pushing away U-shaped push rod 7, the setting of T shape guide groove 6 provided by the utility model exists Between adjacent drawing liquid chamber, and the center of circle of the extending direction on the both sides of T shape guide groove 6 respectively with two neighboring drawing liquid chamber 5 exists On same straight line, that is to say, that the both sides of each T shape guide groove 6 are in the radial position of two neighboring drawing liquid chamber 5, such Words, can guarantee first U-shaped push rod 7 can along the axial drawing liquid of drawing liquid chamber 5, secondly can guarantee by push away U-shaped push rod 7 when It waits, the torque that U-shaped push rod 7 is located at the generation of thrust suffered by the part outside sampler barrel 1 is zero, is taken to reduce U-shaped push rod 7 and be located at The offset of part inside sample cylinder is minimum, and then is conducive to operator and can preferably grasp by the dynamics for pushing away U-shaped push rod 7, mentions High drawing liquid efficiency.

Further, the axial length of T shape guide pad provided by the utility model is less than the axial direction length of T shape guide groove 6 The 1/4 of degree, on the one hand can guarantee effective axial movement length of U-shaped push rod 7, on the other hand can reduce and T shape guide groove 6 Between extruding, be conducive to improve the fluency by U-shaped push rod 7 is pushed away.

In order to improve efficiency of pushing pin, the utility model is worn on sampling probe is connected to rubber 10 of pushing pin, the shape in the present apparatus Shape is preferably cone, and puncture when directly squeezes rubber of pushing pin with hand makes its compress sampling probe, increase operator's finger with The frictional force of sampling probe is conducive to for being fast and effeciently inserted into patient's body cavity sampling probe.

The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent The equivalent embodiment of variation is applied to other fields, but all without departing from the content of the technical scheme of the utility model, according to this reality With novel technical spirit any simple modification, equivalent variations and remodeling to the above embodiments, it is practical new to still fall within this The protection scope of type technical solution.
