[0002] After performing surgical operations, in many cases, drainage tubes need to be placed. The shorter time is 3 to 5 days, and sometimes it takes longer. Nurses need to hand over the shift and measure the exposed scale of the drainage tube to ensure that the drainage tube is in place. At present, all drainage tubes do not have intuitive scales, and the exposed scale needs to be manually measured, which increases the workload of nurses. Since the dislodgment of the drainage tube will affect the recovery of patients, increase the pain and economic burden of patients, therefore, being able to directly see the exposed scale during the nurse's inspection can effectively prevent the drainage tube from shifting and falling off.

A coil that is in up-and-down sliding fit with the hose is sleeved on the hose, and the coil has elasticity. A fixing ring is horizontally fixed at the top end of the coil, and a fixing belt for fixing it on the patient's body is arranged outside the fixing ring. An adjusting component for fixing it on the drainage tube is arranged at the bottom end of the hose.

[0006] Further, the adjusting component includes a plurality of clamping blocks that are in clamping fit. A limiting ring for enabling the clamping blocks to clamp and fix the drainage tube is arranged at the bottom end of the hose, and the clamping blocks expand outward in the natural state.

[0007] Further, the overall shape of the clamping block is an arc structure. When the clamping blocks are mutually attached, a tubular structure that closely fits the drainage tube is formed, and the diameter of the tubular structure formed by the clamping blocks is equal to the diameter of the drainage tube.

[0008] Further, the limiting ring has internal threads on its inner wall, and external threads that are in threaded fit with it are arranged on the bottom end of the hose and the outer side wall of the clamping block. A blocking block for preventing the limiting ring from falling off is arranged at the movable end of the clamping block.

[0019] The following further illustrates the utility model through specific embodiments in conjunction with the attached drawings, but is not used to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the present invention.

[0020] Embodiment 1

[0021] A negative - pressure drainage ball device described in this embodiment, as shown in Figure 1 and Figure 2As shown in the figure, it includes a drainage ball body 1. The drainage ball body 1 includes a drainage ball and a drainage tube. A monitoring component for visually displaying the length of the drainage tube is provided on the drainage tube located outside the patient's body, and the monitoring component is in sliding fit with the drainage tube, which is convenient for clearly and intuitively displaying the state of the drainage tube, thereby reducing the work difficulty of nurses, effectively avoiding the pain and economic losses of patients caused by the failure to timely detect the displacement of the drainage tube, and also being convenient for adjusting the position as needed to make it more applicable. At the same time, it can also be installed on other catheters that need to monitor the length in real time, thereby improving the effect and reducing the use cost;

[0022] The negative pressure drainage ball is a prior art, which is composed of a negative pressure drainage ball, a solid drainage tube and a tunnel needle. It is mainly used in clinical practice in cooperation with the drainage tube to suck out pus exudate, effusion and tissue fluid through negative pressure. It is applicable to small surgeries. During the postoperative recovery process, it can reduce tissue damage, prevent the separation of the wound source and bacterial growth caused by a large amount of fluid accumulation, thereby improving the wound healing effect. Because the negative pressure drainage ball is small in size and convenient to carry around, such as being placed in the upper pocket of the clothes or fixing the handle on the clothes with a safety pin, it is beneficial for the patient to get out of bed early after surgery. Using the negative pressure drainage ball to drain the wound does not require pressure dressing, which is beneficial for the patient's respiratory movement and convenient for observing. The drainage wound above is only covered with a dressing, which is beneficial for observing the wound, such as whether there is bleeding or exudation.

[0023] Embodiment 2

[0024] This embodiment further illustrates the technology. As Figure 1 shown, the monitoring component includes a vertically arranged hose 2, and a scale line 6 for displaying the length is provided on the outer surface of the hose 2, which is not only convenient for sleeving on the drainage tube to display the length of the drainage tube, but also convenient for protecting the drainage tube to avoid its bending and affecting the use;

[0025] A coil 3 that is in up-and-down sliding fit with the hose 2 is sleeved on the hose 2, and the coil 3 has elasticity, which is not only convenient for sleeving on the hose 2 and sliding with it, but also convenient for following the shape change of the drainage, so that it can move flexibly on the hose 2 and the drainage tube;

[0026] A fixing ring 5 is horizontally fixed at the top end of the coil 3. A fixing band 4 for fixing it to the patient's body is provided on the outer side of the fixing ring 5. An adjusting component for fixing the bottom end of the hose 2 to the drainage tube is provided at the bottom end of the hose 2, which is convenient for fixing the top end of the coil 3 to the patient's body and fixing the bottom end of the hose 2 to the drainage tube, so that when the drainage tube generates displacement, it drives the hose 2 to move, and thus judges whether the drainage tube is displaced according to the change in the position of the scale line 6 on the hose 2 of the hose 2.

[0027] Embodiment 3

[0028] This embodiment further illustrates the technology. As Figure 1 andFigure 2 As shown, the adjusting component includes several clamping blocks 8 that are clamped and matched. A limiting ring 7 is provided at the bottom end of the hose 2 for clamping and fixing the drainage tube by the clamping blocks 8. In the natural state, the clamping blocks 8 expand outward, facilitating the hose 2 to be threaded onto the drainage tube and then enabling the clamping blocks 8 to clamp the drainage tube through the limiting ring 7, thereby fixing the hose 2 on the drainage tube.

[0029] Example 4

[0030] This example further illustrates the technology. As Figure 1 and Figure 2 shown, the clamping block 8 is integrally arc-shaped. When the clamping blocks 8 are in contact with each other, they form a tubular structure that closely fits the drainage tube, and the diameter of the tubular structure formed by the clamping blocks 8 is equal to the diameter of the drainage tube. This facilitates increasing the contact area with the drainage tube to make the clamping more firm, and at the same time, it is also convenient to reduce the extrusion of the drainage tube, avoiding causing large deformation to it when clamping the drainage tube by the clamping blocks 8 and affecting its use.

[0031] Example 5

[0032] This example further illustrates the technology. As Figure 1 and Figure 2 shown, the limiting ring 7 has internal threads on its inner wall. External threads that are in threaded cooperation with it are provided at the bottom end of the hose 2 and on the outer wall of the clamping block 8. A stop block for preventing the limiting ring 7 from falling off is provided at the movable end of the clamping block 8, facilitating clamping the drainage tube by driving the clamping blocks 8 to close by rotating the limiting ring 7, fixing the hose 2 on the drainage tube, and at the same time making the hose 2 and the clamping blocks 8 more stable and not easily falling off due to shaking. The setting of the stop block not only facilitates preventing the limiting ring 7 from falling off the clamping block 8 but also improves the connection tightness between the limiting ring 7 and the clamping block 8.

[0033] Example 6

[0034] This example further illustrates the technology. As Figure 1 and Figure 3 shown, an elastic connecting rope 9 is provided between the top end of the hose 2 and the fixing ring 5, facilitating avoiding the direct separation of the hose 2 and the coil 3 and causing loss and damage;

[0035] The length of the connecting rope 9 can be adjusted according to actual needs as long as it is less than the length of the hose 2.

[0036] Example 7

[0037] This example further illustrates the technology. As Figure 1 and Figure 4As shown, the top surface of the fixing belt 4 is provided with a pressure-sensitive adhesive for adhering to the patient's body, which is convenient for fixing on the patient's body and improving the patient's comfort, and avoiding adhesive residue on the patient's body when detaching;

[0038] The fixing belt 4 can also be adhered to the adhesive tape fixing the puncture point of the drainage tube, thereby reducing the discomfort of the patient.

[0039] Example 8

[0040] This embodiment further illustrates the technology. Figure 4 As shown, the coil 3 is provided with a limiting rope for fixing its length, which is not shown in the figure, so that the coil 3 can be slightly bent while the length is fixed, so as to avoid the coil 3 being stretched during use so that the scale line 6 on the hose 2 displays inaccurate data;

[0041] The limiting rope can be made of hemp rope, cotton rope, etc., and at least two groups of them are fixed to the outer wall of the coil 3 to form a whole;

[0042] The coil 3 can also be made of the same material as the hose 2 , and the inner wall of the coil 3 and the outer wall of the hose 2 are both smooth surfaces, so that the hose 2 and the coil 3 can slide flexibly.

[0043] Working principle: first install the hose 2 in the coil 3, then install the hose 2 on the drainage tube, and fix the coil 3 to the patient's body end through the fixing belt 4, and then fix the hose 2 on the drainage tube through the limit ring 7 and the clamp block 8. During the fixing process, pay attention to adjusting the relationship between the coil 3 and the scale line 6. When the drainage tube moves outward, it will drive the hose 2 to slide in the coil 3. When the hose 2 slides, the scale line 6 will be exposed more, so that the nurse can quickly and intuitively observe the condition of the drainage tube;

[0044] The bottom surface of the coil 3 is coated with a prominent color paint, and the scale lines 6 are marked with corresponding values ​​using color paint, so that the nurse can quickly observe the corresponding values.
