Abstract
The utility model discloses a bronchus inner-diameter measurement device, comprising a handle, a scale ruler, a duct and a measurement portion, wherein the scale ruler passes through the handle and is arranged on the handle, one end of the handle is connected with the duct and another end of the duct is provided with the measurement portion. The real-time measurement can be directly performed under a bronchoscope, so as to prevent secondary breast CT examination of the patient. The bronchus inner-diameter measurement device is simple and accurate. The medical resource is saved.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of bronchus inner diameter measuring device.
Background technology
The aspects such as estimating the air flue pathological changes order of severity, clinical efficacy and guiding clinical treatment that is evaluated at of trachea, bronchus internal diameter plays an important role.The method of measuring trachea, bronchus internal diameter at present both at home and abroad mainly comprises: measure tracheal diameter by o n plain chest films 1.; Because o n plain chest films tracheal wall sideline is fuzzy, lines are unclear, thus the data inaccuracy of method measurement.2. utilize CT to measure trachea and main bronchus internal diameter; The data that this method records are more accurate, having overcome X line plain film measures inaccuracy and with patient's truthful data the shortcoming of error is arranged, but the iconography data still have gap with the air flue pathological changes of complexity, can't reflect that particularly the patient inhales the variation of the air flue internal diameter of moments such as expiration.3. assessment technology in the bronchoscope air flue; Mainly by empirical ocular estimate or object of reference method assessment relatively, the result often is subjected to the influence of subjective factors to appraisal procedure, and is accurate inadequately under traditional tracheascope.The method that adopts the interior measuring instrument of air flue directly to measure can write down the data of air flue internal diameter accurately, but owing to there is not measuring instrument in convenient, the practical air flue at present clinically, difficult clinically enforcement, along with increasing of airway disorders and carrying out of air flue interventional therapeutic technique, the measurement of air flue internal diameter and assessment need accurately and measuring device easy to use.
The utility model content
The purpose of this utility model provides a kind of bronchus inner diameter measuring device, can directly measure in real time under tracheascope, the operating process of avoiding the capable once more breast CT of patient to check, easy, accurate and saving medical resource.
To achieve these goals, this utility model is by the following technical solutions:
A kind of bronchus inner diameter measuring device wherein, comprises handle, rule, conduit and measurement section, and described rule installs and is arranged on the handle, an end connecting duct of handle, and the other end of conduit is provided with measurement section.
Further, described measurement section comprises inner core and the tentacle more than three.
Further, described tentacle is a V-type.
The beneficial effects of the utility model are:
This utility model can make things convenient for, accurately measure trachea, bronchus internal diameter, and measuring instrument can directly be measured under bronchoscope in real time in the bronchoscope air flue, the operating process of avoiding the capable once more breast CT of patient to check, easy, accurate and saving medical resource.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following description or the accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of this utility model measurement section;
Fig. 3 is this utility model measuring principle sketch map;
Fig. 4 is this utility model measuring principle functional image sketch map.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further described:
As shown in Figure 1 and Figure 2, this utility model comprises rule 1, handle 2, conduit 3 and measurement section 4, rule 1 is installed on the handle 2, rule 1 can slide in handle 2, the other end of handle 2 is connected with conduit 3, pipe 31 and outer tube 32 in conduit 3 comprises, interior pipe 31 1 ends are equipped with measurement section 4, measurement section 4 is made up of inner core and three tentacles, and tentacle is a V-type, and inner core works to support tentacle, when rule 1 sliding extension, the tentacle of measurement section 4 opens or shrinks, and reads corresponding numerical value thus on rule 1, and this numerical value is trachea, bronchus internal diameter.When the tentacle of measurement section 4 is two, since twisting force, the easy wrench deformation of tentacle, and measurement result is inaccurate.
Fig. 3 is a measuring principle sketch map of the present utility model, and h is trachea, bronchi radius among Fig. 3, and L is a constant, i.e. bending section length, and d is the sliding distance of rule 1.Concrete measuring method: use earlier
Formula calculates the bronchus internal diameter, and three measurements are averaged; The bronchus cross-sectional area is then according to S=Π h
2Calculate, measure gained h calculating mean value according to three times.Figure 4 shows that
Functional image, among the figure with
Be example, promptly during L=6, trachea, bronchi radius value h change between 0-6.
When using this utility model to measure trachea, bronchus internal diameter, measurement section 4 and conduit 3 are entered in the trachea through the biopsy duct of tracheascope, stretching rule 1, the inner core of measurement section 4 and tentacle stretch out from interior pipe, and tentacle opens, when the mirror of tracheascope is observed tentacle to tracheobronchial inwall the time, on rule 1, read sliding distance, calculate trachea, bronchus internal diameter according to formula, three measurements are averaged, and obtain final trachea, bronchus inner diameter values.After measurement finishes, shrink rule 1, rule 1 is got back to the home position, and the inner core of measurement section 4 and tentacle are retracted in the interior pipe of conduit 3.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, as change the number of measurement section tentacle, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
