Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical care, in particular to an auxiliary tool for measuring the prolapsed length of a drainage tube. Background Art
[0002] A drainage tube is a medical device that guides pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. When in use, one end of the drainage tube is inserted into the drainage site in the body or on the wound surface, and the other end can be connected to other external devices such as drainage tubes outside the body to drain the fluid outside the body through the pressure of the body, gravity, or negative pressure suction.
[0003] After the drainage tube is set, the nursing staff needs to pay attention to whether the drainage tube is out of the patient's skin and the specific length of the outfall. The conventional nursing approach is to regularly measure the length of the drainage tube outside the patient's skin and record it, and compare the subsequent measured length value with the first measured length value. If the subsequent measured length value is greater than the first measured length value, it proves that the drainage tube is out of the state, and the specific length value of the outfall is obtained by subtracting the two. The above operation process is relatively cumbersome. On the one hand, common length measurement tools such as soft tape measures need to be rolled up and stored, which wastes time, and steel tape measures are large in size and inconvenient to carry; on the other hand, reading errors will occur in the process of measuring the length of the drainage tube for the first time and the subsequent measurement of the length of the drainage tube. Calculation errors will also occur in the process of subtracting the subsequent measured length value from the first measured length value, resulting in a significant increase in the inaccuracy of the final drainage tube outfall length value. Utility Model Content
[0004] The utility model aims to provide a drainage tube prolapse length measurement auxiliary tool, which is convenient for obtaining the drainage tube prolapse length value, and the obtained drainage tube prolapse length value has high accuracy.
[0005] In order to solve the above technical problems, the specific solution adopted by the utility model is: a drainage tube dislodged length measuring auxiliary tool, including a measuring tube for the drainage tube body to pass through, a perforation is provided at one end of the measuring tube wall, and measurement scale lines are distributed along the longitudinal direction of the measuring tube.
[0006] Preferably, a slide groove distributed along the longitudinal direction of the measuring tube is provided on the tube wall of the measuring tube, and a marking slider is slidably provided in the slide groove.
[0007] Preferably, the marking slider is I-shaped, the narrow portion in the middle of the marking slider is adapted and slidably matched with the slide groove, and the wide portions on both sides of the marking slider are respectively located on the inner and outer sides of the tube wall of the measuring tube.
[0008] Preferably, two slide grooves are symmetrically provided on the measuring tube, and the marking sliding blocks are provided in both slide grooves.
[0009] Preferably, two slide grooves are symmetrically provided on the measuring tube, the marking slider is U-shaped, and the two ends of the marking slider are respectively engaged and slidably matched with the two slide grooves.
[0010] Preferably, each end of the marking slider is provided with a sliding column slidably matched with the sliding groove, the outer end of the sliding column is fixed to the marking slider, and the inner end is fixed with an anti-falling block.
[0011] Preferably, the measuring scale lines are arranged on the sliding track of the marking slide block along the slide groove.
[0012] Preferably, the zero line of the measuring scale corresponds to the perforation.
[0013] Preferably, the cross section of the tube body of the measuring tube is semicircular.
[0014] Preferably, the material of the measuring tube is hard plastic.
[0015] The end of the measuring tube of the utility model is provided with a perforation, and the tube wall is provided with a measuring scale line. During the implementation process, the measuring tube is sleeved on the outside of the drainage tube body and the end of the measuring tube with the perforation is used as the reference end to press against the patient's skin, and then a marker or other tool is passed through the perforation to draw a dot mark on the outside of the drainage tube body. When the drainage tube is subsequently inspected, the above operation is followed again and dot marks are drawn, and then it is observed whether the subsequent dot marks coincide with the first dot marks. If they coincide, it proves that the drainage tube has not fallen out, otherwise it proves that the drainage tube has fallen out, and the interval reading of the two dot marks on the measuring scale line is the prolapse length of the drainage tube. Therefore, the utility model has a simple structure and is easy to implement. The prolapse length of the drainage tube can be obtained by only one reading, which is not only convenient for medical staff to quickly obtain the result, but also avoids the error caused by calculation errors in the prior art, greatly improving the accuracy of the measurement.

[0023] The technical solution of the utility model is described below through three embodiments:
[0024] Example 1
[0025] like Figure 1 As shown, a drainage tube dislodged length measuring auxiliary tool of this embodiment is a measuring tube 2 with a semicircular cross section. The measuring tube 2 is made of hard plastic material, which is easy to process and low in cost. A perforation 1 penetrating the tube wall is provided at the left end of the measuring tube 2 to cooperate with a marker 5 to mark and draw points. A measuring scale line 3 is provided on the measuring tube 2 along its own length direction, and the dislodged length of the drainage tube body 7 is measured by measuring the auxiliary line. In order to facilitate measurement, the zero line of the measuring scale line 3 in this embodiment corresponds to the center of the perforation 1.
[0026] The following combination Figure 2 and Figure 3 The implementation process of this embodiment is described. Figure 2 and Figure 3 Both Figure 1 A cross-sectional view taken along the AA axis is provided to show the position of the through hole 1.
[0027] like Figure 2 As shown, after the drainage tube body 7 is fixed, the measuring tube 2 of this embodiment is sleeved on the outside of the drainage tube body 7, and the left end of the measuring tube 2 is pressed against the patient's skin 4, and then a marking pen 5 is passed through the perforation 1 on the side for convenient operation and a marking point 6 is drawn on the outer wall of the drainage tube body 7, and the measuring tube 2 is removed after drawing the point.
[0028] like Figure 3 As shown, in the subsequent measurement, the measuring tube 2 is again put on the outside of the drainage tube body 7 and the left end of the measuring tube 2 is pressed against the patient's skin 4. From the top notch of the measuring tube 2, it is observed that the above-mentioned mark point 6 does not correspond to the position of the perforation 1, that is, it is judged that the drainage tube body 7 has been dislodged. Because the zero line of the measuring scale line 3 corresponds to the perforation 1, Figure 3 The reading of the measuring scale line 3 where the marking point 6 is shown is the prolapse length of the drainage tube body 7. After recording the prolapse length, the nursing staff can easily draw the marking point 6 again on the side wall of the drainage tube body 7 through the perforation 1 for the next measurement.
[0029] Example 2
[0030] like Figure 4 and Figure 5 ( Figure 5 for Figure 4 The difference between this embodiment and the first embodiment is that both sides of the measuring tube 2 of this embodiment are provided with a chute 9 penetrating the tube wall, and a marking slider 8 is slidably arranged in the chute 9. The marking slider 8 is in an I-shape, with a smaller outer diameter in the middle corresponding to the width of the chute 9 to fit the sliding fit of the chute 9, and a larger outer diameter at both ends to achieve an anti-slip function. One end located inside the measuring tube 2 is used to align with the marking point 6, and the other end located outside the measuring tube 2 is used to assist in measuring the reading of the scale line 3, specifically:
[0031] In subsequent measurements after marking the marking point 6 on the outer wall of the drainage tube body 7 by the same method as in Example 1, Figure 5 As shown, move the marking slider 8 on the side close to the marking point 6 until the inner end of the marking slider 8 corresponds to the marking point 6. At this time, the reading of the measuring scale line 3 corresponding to the outer end of the marking slider 8 is the protruding length of the drainage tube body 7.
[0032] Since the present embodiment has the marking slider 8 as a comparison, the accuracy of the reading is further improved compared with the embodiment 1.
[0033] Example 3
[0034] Similar to the second embodiment, the present invention also assists reading by marking the slider 8, the difference is that Figure 6-7 As shown, the marking slider 8 in this embodiment is U-shaped, and a slide column 11 is fixed at both ends. The slide column 11 passes through the slide groove 9 on the corresponding side into the measuring tube 2 and is fixed with an anti-falling block 10 whose size is larger than the width of the slide groove 9.
[0035] The implementation process of this embodiment is the same as that of embodiment 2, and will not be described in detail. Since the marking slider 8 of this embodiment is integrated, the structure of this embodiment is more stable on the one hand, and the marking slider 8 partially overlaps the measurement scale line 3 on the other hand, thereby further improving the accuracy of the reading.
