Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical care, and specifically relates to a drainage tube length monitor. Background Art
[0002] The length of the drainage tube exposed outside the patient's skin after surgery and the possible prolapse length need to be regularly monitored and recorded by nursing staff. The length of the drainage tube exposed outside the patient's skin can be directly measured with a measuring scale, and the prolapse length is obtained by subtracting the initially measured exposed length from the subsequently measured exposed length. The following inconveniences exist in the specific operation:
[0003] Firstly, regarding the measuring tool, common plastic ones are long in length, inconvenient to carry and easy to break. Although soft tape measures and steel tape measures are easy to carry, soft tape measures are prone to winding and knotting, and steel tape measures are prone to scratches during rapid retraction due to improper operation.
[0004] Secondly, regarding the measurement accuracy, especially the measurement accuracy of the prolapse length of the drainage tube. On the one hand, reading errors will occur both during the first measurement of the drainage tube length and the subsequent measurement of the drainage tube length. On the other hand, calculation errors will also occur during the process of subtracting the subsequently measured length value from the first measured length value, resulting in a significant increase in the inaccuracy of the finally obtained prolapse length value of the drainage tube. Summary of the Invention
[0005] The present invention aims to provide a drainage tube length monitor, which is convenient for storage and carrying and conducive to improving the measurement accuracy.
[0006] To solve the above technical problems, the specific solution adopted by the present invention is as follows: A drainage tube length monitor includes a monitoring tube and an extension tube that slides longitudinally on the monitoring tube. The lumens of both the monitoring tube and the extension tube can allow the body of the drainage tube to pass through. One end of the monitoring tube is used to abut against the patient's skin and is provided with a first marking hole. The end of the extension tube away from the first marking hole is used to align and cooperate with the tail end of the drainage tube body. Both the monitoring tube and the extension tube are provided with size scale lines along the longitudinal direction.
[0007] Preferably, the cross-sections of both the monitoring tube and the extension tube are semi-circular.
[0008] Preferably, the diameter of the monitoring tube is larger than that of the extension tube, and both sides of the monitoring tube have flanges distributed inward to prevent the extension tube from prolapsing.
[0009] Preferably, guide posts are provided on the inner wall of the monitoring tube, and sliding grooves that slidably cooperate with the guide posts are provided on the outer wall of the extension tube.
[0010] Preferably, both ends of the sliding groove are closed.
[0011] Preferably, the monitoring tube and the extension tube are of equal length, and a second marking hole is provided at the end of the extension tube corresponding to the first marking hole, and the second marking hole can correspond to the first marking hole as the extension tube slides along the monitoring tube.
[0012] Preferably, the zero line of the size scale lines on the monitoring tube is located at the end of the monitoring tube where the first marking hole is provided, and the zero line of the size scale lines on the extension tube is located at the end of the extension tube away from the first marking hole.
[0013] Preferably, an auxiliary marking mechanism is provided at a position corresponding to the first marking hole on the monitoring tube, and the auxiliary marking mechanism includes a pen tube fixed on the outer tube wall of the monitoring tube and a marking pen tip fixed in the pen tube, and the marking pen tip is distributed in the direction of the first marking hole. The pen tube has a flexible material so that the marking pen tip can be inserted into the first marking hole by pressing the pen tube, thereby making a dot mark on the drainage tube body located in the monitoring tube.
[0014] Preferably, the first marking hole is a strip hole and is distributed along the circumference of the monitoring tube, the width of the first marking hole corresponds to the outer diameter of the marking pen tip, and the length of the first strip hole is 1.5-2 times the outer diameter of the marking pen tip.
[0015] Preferably, the pen tube includes a rigid base fixed on the monitoring tube and a flexible portion fixed on the rigid base opposite to one end of the monitoring tube, and the tail end of the marking pen tip is plugged into and fitted on the flexible portion. Beneficial Effects
[0016] The measuring body in the present invention is a monitoring tube and an extension tube. The extension tube can slide along the monitoring tube and be stored in the monitoring tube, so that the overall length of the present invention is short while having a large measuring range, which is convenient for nursing staff to carry together with tools such as markers.
[0017] The monitoring tube and the extension tube in the present invention are both provided with size scale lines, and the monitoring tube is provided with a first marking hole for inserting tools such as a marker pen to draw a marking point on the drainage tube body.

[0026] The technical solution of the present invention is described below through 3 embodiments:
[0027] Embodiment 1
[0028] As Figure 1 and Figure 8 shown, a drainage tube length monitor in this embodiment includes an equal-length monitoring tube 4 and an extension tube 2, both the monitoring tube 4 and the extension tube 2 are made of rigid plastic. The diameter of the extension tube 2 is smaller than that of the monitoring tube 4 and is in sliding fit with the inner wall of the monitoring tube 4, so that the extension tube 2 can be retracted into the monitoring tube 4 for easy carrying, and the extension tube 2 is pulled out from the monitoring tube 4 during the process of measuring the drainage tube body 6 to increase the range of this embodiment. To prevent the extension tube 2 from slipping out of the monitoring tube 4, as shown in combination with Figure 1 and Figure 4 shown, on the one hand, flanges 9 distributed inward are provided on both sides of the monitoring tube 4, and the lower edges of the flanges 9 are in contact with and in sliding fit with the upper edges on both sides of the extension tube 2, so as to prevent the extension tube 2 from rotating under the action of external force and slipping out of the monitoring tube 4; on the other hand, a guide post 11 is provided at a position close to the right end of the inner wall of the monitoring tube 4, and a slide groove 10 distributed longitudinally along itself is provided at the outer wall position of the bottom of the extension tube 2, so as to realize the flexible sliding of the extension tube 2 through the sliding fit of the slide groove 10 and the guide post 11, and since both ends of the slide groove 10 are closed, the extension tube 2 is prevented from slipping out of the end of the monitoring tube 4
[0029] Still as Figure 1 and Figure 8As shown, a first marking hole 3 is provided at the left end of the monitoring tube 4 for the nursing staff to insert a marker pen 5 and slide out a marking point 8 on the outer wall of the drainage tube body 6 located in the monitoring tube 4 and the extension tube 2. At the same time, dimension scale lines 1 are provided longitudinally on the monitoring tube 4 and the extension tube 2, respectively. The lengths of the two sets of dimension scale lines 1 are both 10CM, and the minimum scale is 1MM. The zero line of the dimension scale lines 1 located on the monitoring tube 4 is located at the left end of the monitoring tube 4, and the center of the first marking hole 3 is located at 5MM of the dimension scale lines 1 on the monitoring tube 4, that is, the center of the first marking hole 3 is 5MM away from the left end of the monitoring tube 4; the starting line of the dimension scale lines 1 located on the extension tube 2 is 10CM and is located at the right end of the extension tube 2, and increases to 11, 12, 13-20CM to the left. Based on the above structure, the specific application process of this embodiment is as follows:
[0030] The first marking measurement after the drainage tube is installed is as follows: the drainage tube body 6 is inserted into the monitoring tube 4 and the extension tube 2, and the left end of the monitoring tube 4 is placed against the patient's skin 15. If the exposed length of the drainage tube body 6 is less than 10CM, the reading at the point where the end of the drainage tube body 6 is located using the size scale line 1 on the monitoring tube 4 is the exposed length of the drainage tube body 6. If the exposed length of the drainage tube body 6 is greater than 10CM, then Figure 2 ( Figure 2 and below Figure 3 In the implementation process of this embodiment, Figure 1 As shown in the structural schematic diagram of the AA section shown in FIG, the extension tube 2 is pushed and pulled so that the right end of the extension tube 2 is aligned with the end of the drainage tube body 6. At this time, the projection reading of the right end of the monitoring tube 4 on the size scale line 1 on the extension tube 2 is used, and the reading is the exposed length of the drainage tube body 6. After the exposed length of the drainage tube body 6 is read and recorded, a marking pen 5 is inserted into the first marking hole 3 to draw a marking point 8 on the outer wall of the drainage tube body 6.
[0031] In the present embodiment, a second marking hole 7 is further provided at the left end of the extension tube 2, and the second marking hole 7 coincides with the first marking hole 3 when the extension tube 2 is fully received in the monitoring tube 4, so that when the exposed length of the drainage tube body 6 is less than 10CM and there is no need to move the position of the extension tube 2, the marking pen 5 can be passed through the first marking hole 3 and the second marking hole 7 in sequence to draw a marking point 8 on the drainage tube body 6.
[0032] During the subsequent monitoring of the drainage tube body 6 after the first marking measurement, the drainage tube body 6 is again inserted into the monitoring tube 4 and the extension tube 2, and the left end of the monitoring tube 4 is placed against the patient's skin 15 to observe whether the position of the first marking point 8 coincides with the first marking hole 3. If it does not coincide and is located on the right side of the first marking hole 3, it proves that the drainage tube body 6 has partially fallen out. Figure 3As shown, if the marking point 8 is still located in the monitoring tube 4, then read the reading of the marking point 8 on the size scale line 1 on the monitoring tube 4, minus 5MM to obtain the protruding length of the drainage tube body 6. If the marking point 8 exceeds the monitoring tube 4, pull out the extension tube 2 again to align the right end of the extension tube 2 with the marking point 8, read the reading of the right end of the monitoring tube 4 on the size scale line 1 on the extension tube 2, minus 5MM to obtain the protruding length of the drainage tube body 6. It should be noted that although the protruding length of the drainage tube body 6 measured in this embodiment is calculated by subtracting a specific length from the reading, the subtracted length is a specific length of 5MM, the calculation is relatively simple, and the probability of calculation error is greatly reduced, which is conducive to ensuring the accuracy of the result.
[0033] Example 2
[0034] like Figure 4 As shown, the main structure of this embodiment is the same as that of embodiment 1, and the only difference is that two sets of upper and lower size scale lines 1 are provided on the same side of the monitoring tube 4 and the extension tube 2 in this embodiment. The distribution mode of the size scale lines 1 located at the upper part of the monitoring tube 4 and the extension tube 2 is exactly the same as that of embodiment 1, and is exactly the same as the application method of measuring the exposed length of the drainage tube body 6 recorded in embodiment 1. The size scale lines 1 at the lower part of the extension tube 2 are still distributed in the same way as the upper scale lines of the extension tube 2, but the zero line of the size scale lines 1 at the lower part of the monitoring tube 4 coincides with the center of the first marking hole 3. When the center of the first marking hole 3 is kept 5MM away from the left end of the monitoring tube 4, an indicator block 16 with a length of 5MM is provided at the right end of the monitoring tube 4 corresponding to the right end of the lower size scale line 1, and the reading of the size scale line 1 on the extension tube 2 is assisted by the right end of the indicator block 16. Specifically:
[0035] The drainage tube body 6 is measured for the first time and the marking point 8 is drawn. In the subsequent monitoring, the drainage tube body 6 is again sleeved into the monitoring tube 4 and the extension tube 2, and the left end of the monitoring tube 4 is touched to the patient's skin 15. It is observed whether the position of the marking point 8 made for the first time coincides with the first marking hole 3. If it does not coincide and is located on the right side of the first marking hole 3, it proves that the body of the drainage tube has been partially dislodged. If the marking point 8 is still located in the monitoring tube 4, then read the reading of the lower size scale line 1 on the monitoring tube 4 where the marking point 8 is located at this time, and this reading is the dislodged length of the drainage tube body 6. If the marking point 8 exceeds the monitoring tube 4, then pull out the extension tube 2 again to align the right end of the extension tube 2 with the marking point 8, and read the reading of the right end of the indicator block 16 on the size scale line 1 at the upper and lower parts of the extension tube 2, and this reading is the dislodged length of the drainage tube body 6.
[0036] In this embodiment, the exposed length and the protruding length of the drainage tube body 6 do not need to be calculated, thereby avoiding calculation errors and further ensuring the accuracy of the monitoring results.
[0037] Example 3
[0038] As Figure 6 and Figure 7 shown, in this embodiment, an auxiliary marking mechanism is provided at the first marking hole 3, and a marking point 8 can be drawn on the drainage tube body 6 by pressing the auxiliary marking mechanism, which further facilitates the operation of the nursing staff.
[0039] The auxiliary marking mechanism includes a pen tube 14 fixed on the monitoring tube 4 and a marking pen tip 12 arranged in the pen tube 14. The pen tube 14 has a rigid base 1401 made of rigid plastic fixed on the monitoring tube 4 and a flexible part 1402 fixed on the rigid base 1401. The flexible part 1402 is made of silica gel and deforms under pressure and can automatically reset after the pressure disappears. The marking pen tip 12 is a conventional small marker pen 5, which has a pen tip and a small ink sac for supplying ink to the pen tip. In the natural state of the flexible part 1402, the pen tip is located in the first marking hole 3, the small ink sac is located at the tail end of the marking pen tip 12 and is provided with a cover body 13. The cover body 13 passes through the flexible part 1402 and is exposed. During the process of pressing the flexible part 1402, the pen tip moves towards the inside of the monitoring tube 4 and contacts the drainage tube body 6, so as to draw a marking point 8 on the outer side wall of the drainage tube body 6.
[0040] In addition, the first marking hole 3 in this embodiment is a strip-shaped hole and is distributed along the circumferential direction of the monitoring tube 4. The width of the first marking hole 3 corresponds to the outer diameter of the marking pen tip 12, and the length of the first strip-shaped hole is 1.5 times the outer diameter of the marking pen tip 12. Thus, a limit is formed in the width direction of the first marking hole 3, so that during the process of pressing the flexible part 1402, the pen tip of the marking pen tip 12 can only swing in the circumferential direction of the drainage tube body 6, and the marking point 8 drawn on the outer side wall of the drainage tube body 6 is linear, which is more convenient to compare with the size scale line 1 than the dot-shaped marking point 8 to ensure the monitoring accuracy.
