Abstract
This application discloses a kind of thoracentesis needle, comprise needle body, the needle handle be connected with needle body and be sheathed on the needle guard of needle body, needle guard is provided with scale, and needle guard one end is connected to needle handle, and needle guard is provided with pars contractilis near one end of needle handle, and needle guard is provided with multiple broken part.Thus, by arranging scale on needle guard, the degree of depth of inserting needle can be determined accurately, by arranging pars contractilis, fine adjustments can be carried out to the degree of depth of inserting needle, reaching best depth of needle, prevent inserting needle from crossing dark or excessively shallow.
Description
Technical field
This utility model relates to thoracentesis needle, particularly relates to a kind of easy thoracentesis needle controlling to insert the depth.
Background technology
Medically the way of thoracentesis is adopted to treat to intrathoracic hydrops, pneumatosis at present; puncture needle used by being arranged with the piercing needle of needle guard, glass connection tube, connecting silicone pipe form; needle guard shields, and connects syringe after pulling out needle guard, connecting silicone pipe during use.When using clinically, general medical personnel determine depth of needle by range estimation, and inserting needle is excessively dark, can puncture alveolar and cause pneumothorax, and inserting needle is shallow not easily aspirates hydrops, are difficult to grasp the degree of depth that syringe needle enters torso model.
Utility model content
The purpose of this utility model is to provide a kind of thoracentesis needle, solves one or more in above-mentioned prior art problem.
According to an aspect of the present utility model, a kind of thoracentesis needle is provided, comprise needle body, the needle handle be connected with needle body and be sheathed on the needle guard of needle body, the syringe needle of needle body is in needle guard, needle guard is provided with scale, needle guard one end is connected to needle handle, and needle guard is provided with pars contractilis near one end of needle handle, and needle guard is provided with multiple broken part.
In some embodiments: the initial value of scale is 0, and the initial value of scale is positioned at the equal-height position of needle guard and needle body syringe needle, and increases gradually towards the deflection scale of needle handle.Depth of needle can be determined accurately thus.
In some embodiments: the every lattice of scale are 0.1CM.Depth of needle can be determined accurately thus.
In some embodiments: the integer value place of scale is located in broken part.Depth of needle can be determined accurately thus.
In some embodiments: pars contractilis comprises the folding line arranged continuously, and the distance of stretch out and draw back of pars contractilis is 1CM.
In some embodiments: pars contractilis comprises ten folding lines arranged continuously, and the distance of stretch out and draw back of each folding line is 0.1CM.Fine adjustments can be carried out to the degree of depth of inserting needle thus, reach best depth of needle.
In some embodiments: broken part is the vestige that fractures around needle guard.Can be fractureed needle guard thus.
This utility model, by arranging scale on needle guard, can be determined the degree of depth of inserting needle accurately, by arranging pars contractilis, can carry out fine adjustments, reach best depth of needle to the degree of depth of inserting needle, prevent inserting needle from crossing dark or excessively shallow.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of thoracentesis needle of this utility model.
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing, this utility model is described in further detail.
As shown in Figure 1, a kind of thoracentesis needle, comprise needle body 1, the needle handle 2 be connected with needle body 1 and the needle guard 3 being sheathed on needle body 1, the syringe needle of needle body 1 is in needle guard 3, one end of the non-syringe needle of needle body 1 is inserted in needle handle 2, and needle handle 2 is for connecting glass connection tube or rubber tube.
Needle guard 3 is provided with scale 4, and the initial value of scale 4 is 0, and the initial value of scale 4 is positioned at the equal-height position of needle guard 3 and needle body 1 syringe needle, and increases gradually towards the deflection scale of needle handle 2, and the every lattice of scale 4 are 0.1CM, and in addition, the every lattice of scale 4 also can be 1CM.
Needle guard 3 is provided with multiple broken part 6, and in the present embodiment, the integer value place of scale 4 is located in broken part 6, and broken part 6 is the vestige that fractures around needle guard 3.Thus, depth of needle can be determined accurately.
In addition, the initial value of scale 4 also can be positioned at the end place that needle guard 3 does not connect described needle handle 2, and now, the syringe needle of needle body 1 is fixed value A to this needle guard 3 end place vertical dimension in face, and it is best when being 0.3CM that this fixed value A can be 0.1-1CM, fixed value A.When now using, the degree of depth of inserting needle is that the length of broken part 6 deducts fixed value A.
Needle guard 3 one end is connected to needle handle 2, and needle guard 3 can one-body moldedly be connected with needle handle 2, and needle guard 3 also can detachably be sheathed on needle handle 2 in addition.
Needle guard 3 is provided with pars contractilis 5 near one end of needle handle 2, pars contractilis 5 is identical with the pars contractilis structure of straw, specifically, pars contractilis 5 comprises the folding line 51 arranged continuously, one-body molded connection between each adjacent folding line 51, the distance of stretch out and draw back of pars contractilis 5 is 1CM, in the present embodiment, pars contractilis 5 comprises ten folding lines 51, and the distance of stretch out and draw back of each folding line 51 is 0.1CM.Fine adjustments can be carried out to the degree of depth of inserting needle thus, reach best depth of needle.
In sum, this utility model, by arranging scale on needle guard, can be determined the degree of depth of inserting needle accurately, by arranging pars contractilis, can carry out fine adjustments, reach best depth of needle to the degree of depth of inserting needle, prevent inserting needle from crossing dark or excessively shallow.
The above is only a kind of embodiment of the present utility model; it should be pointed out that to those skilled in the art, under the prerequisite not departing from this utility model creation design; can also make some similar distortion and improvement, these also should be considered as within protection domain of the present utility model.
