Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a sinus tract measuring device. Background Art

[0002] Sinus is a pathological blind tube that occurs under the skin or in the internal organs, with only an external opening but no internal hole. It is caused by the combined effects of multiple diseases and infections. Its characteristics are that the tube leads from deep tissue to the body surface, and the tube may be long or short, straight or curved, with one or more external openings, which are small, and pus is constantly dripping.

[0003] At present, the sinus tract is mostly measured by inserting a cotton swab into the deepest part of the wound, and the direction of the sinus tract is estimated by the tilt direction of the cotton swab. Another utility model patent with prior art announcement number CN217285760U discloses a wound detection device, in which a movable ring is sleeved on the outer side of the measuring probe, and a detection support rod is movably installed on one side of the movable ring through a hinge seat, and marking scales are set on the measuring probe and the detection support rod. When in use, the sterile cotton end of the measuring probe is inserted into the wound, and the detection support rod is adjusted to contact the skin surface to obtain the depth of the wound. The detection support rod and the extension support rod inside it are used to detect the length and width of the wound.

[0004] When the above structure is used to measure the sinus tract, since the structure of the sinus tract is either deep or shallow and is often irregular, sometimes the sinus tract is deep and wide at the deep end but the outer opening is small. In this case, when measuring the width of the deep end of the sinus tract, the above structure is not applicable. In addition, in clinical applications, in addition to measuring the sinus tract, it is often necessary to take samples of the sinus tract for inspection. Therefore, medical staff often need to perform both sinus tract measurement and sampling, which results in low work efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a sinus tract measuring device in view of the deficiencies in the prior art. The device is not only applicable to the measurement of the width of the deep sinus tract under complex conditions and is easy to operate, but also capable of completing sinus tract sampling at the same time for the next step of inspection, thereby improving work efficiency.

[0006] The utility model solves the above-mentioned technical problem with the following technical solutions: a sinus tract measuring device, characterized in that it comprises an angle measuring device and two detection rods with scale markings, one end of the two detection rods is provided with a sterile contact block, and the other end of the two detection rods is provided with a rangefinder for measuring the distance between the ends of the two detection rods; the rod bodies of the two detection rods are connected by a hinge block, the hinge blocks are respectively slidably connected to the two detection rods, and the hinge blocks can rotate around their own axes relative to the detection rods; the angle measuring device is slidably connected to one detection rod, and the angle measuring device is respectively parallel to the two detection rods.

[0007] Furthermore, the contact block is a sampling swab.

[0008] Furthermore, a groove fold is arranged on the detection rod, on the upper side of the contact block.

[0009] Furthermore, the rangefinder is a flexible measuring ruler.

[0010] Furthermore, the flexible measuring ruler comprises a shell and a tape measure wound inside the shell, the shell is connected to the detection rod, and the outer end of the tape measure is a free end.

[0011] Furthermore, the angle measuring device is slidably connected to the detection rod via a slider.

[0012] Furthermore, the surface of the detection rod is provided with a first sliding groove which is in the same direction as the axial direction thereof and is adapted to the sliding block.

[0013] Furthermore, the center of the angle measuring device corresponds to the inner edge of the detection rod.

[0014] Furthermore, the hinge block includes a connecting shaft and top plates fixed at both ends of the connecting shaft.

[0015] Furthermore, second slide grooves for the top sheet to slide are arranged on the opposite end surfaces of the two detection rods, and the top sheet can rotate in the second slide grooves, and the outer edge of the second slide groove is provided with a convex edge to prevent the top sheet from slipping out of the second slide groove.

[0016] The beneficial effects of the utility model are:

[0017] 1. The utility model can measure the width of the deep sinus tract by means of two detection rods connected by a hinge block and an angle measuring device and a distance measuring device connected to the detection rods. The utility model is easy to operate and convenient to store.

[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The embodiments given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] like Figure 1-Figure 5 As shown, the sinus tract measuring device of this embodiment includes an angle measuring device 3 and two parallel detection rods with scale markings, including detection rods A1 and B2 of equal length, whose length is m, and the rod bodies are made of plastic material. The a ends of the two detection rods are provided with sterile contact blocks 30 (the starting point of the scale markings is calculated from the end of the contact block 30), and the b ends of the two detection rods are provided with rangefinders 4 for measuring the distance between the ends of the two detection rods; the rod bodies of the two detection rods are connected by hinge blocks 5, and the hinge blocks 5 are respectively connected to the two detection rods in a sliding manner, and the hinge blocks 5 can rotate around their own axes relative to the detection rods; the angle measuring device 3 is slidably connected to the detection rod B2, and the angle measuring device 3 is respectively parallel to the two detection rods. The angle measuring device 3 is specifically a transparent flat protractor structure for measuring the angle formed between the two detection rods.

[0029] In this embodiment, the rangefinder 4 is a flexible measuring ruler, which includes a shell 41 and a soft ruler 42 wound in the shell 41. The shell 41 is connected to the detection rod B2, the outer end of the soft ruler 42 is a free end, and the outlet of the shell 41 is close to the end of the detection rod B2.

[0030] In this embodiment, the angle measuring device 3 is a circular protractor made of transparent material. The angle measuring device 3 is slidably connected to the detection rod B2 through a slider 8. The angle measuring device 3 is fixed on the surface of the slider 8, and the center of the angle measuring device 3 corresponds to the inner edge of the detection rod, that is, the detection rod B2. At this time, the zero-degree line of the angle measuring device 3 overlaps with the inner edge of the detection rod B2, so as to quickly read the angle formed between the two detection rods; accordingly, the surface of the detection rod B2 is provided with a first slide groove 7 with the same direction as its axial direction and adapted to the slider 8.

[0031] In this embodiment, the hinge block 5 includes a connecting shaft 51 and a top sheet 52 fixed at both ends of the connecting shaft 51, and the cross section of the top sheet 52 is circular. Correspondingly, the opposite end surfaces of the two detection rods are provided with a second slide groove 9 for the top sheet 52 to slide, and the top sheet 52 can rotate in the second slide groove 9, and the outer edge of the second slide groove 9 is provided with a convex edge to prevent the top sheet from slipping out of the second slide groove, that is, the second slide groove 9 is a T-slot structure.

[0032] In this embodiment, in order to facilitate the operation of the detection rod, a handle 10 is further provided on the top thereof.

[0033] The method of using the sinus tract measuring device of this embodiment is as follows: insert the two probe rods into the sinus tract through the contact blocks 30 at their ends, and adjust the hinge position of the probe rod A1 and the probe rod B2 and the angle formed by the sliding and rotating connection relationship between the hinge block 5 and the probe rod A1 according to the depth and width of the sinus tract and the size of the external opening, until the two contact blocks 30 touch the width edge of the sinus tract, and then slide the angle measuring device 3 on the probe rod B2 to the intersection of the two probe rods. Measure the angle α between the probe rod A1 and the probe rod B2 through the angle measuring device 3, and read the distance from the a end of the two contact blocks 30 to the intersection of the probe rod A1 and the probe rod B2, and Figure 1 Then take out the sinus tract measuring instrument, adjust the positions of the two probe rods by sliding the hinge block 5, so that the distance from the junction of the probe rod A1 and the probe rod B2 to the B end is the same as the size of m and n, and the included angle is α, that is, the size of the triangle formed by the two sides and the included angle when the sinus tract is measured is restored, as shown in FIG. Figure 6 As shown, at this time, pull out the tape measure to measure the distance between the two ends B, which is the width of the sinus.

[0034] In a preferred embodiment of the utility model, the contact block 30 is a sampling swab, and a groove fold 6 is provided on the probe rod, located on the upper side of the contact block 30. The advantage is that after the sinus width is measured by the sinus measuring device, the sampling swab has completed the sampling, and at this time, the end of the sampling swab can be placed in the test box and the probe rod can be broken at the groove fold 6, leaving only the sampling swab in the test box for inspection.
