[0045] In order to better explain the present application, so as to be understood, the present application is described in detail by specific embodiments in combination with the drawings. In this article, the orientation of "up", "down" and the like is referred to the orientation of the drawings. Figure 1

[0046] Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a clearer, more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0047] As Figure 1 ​As shown, the present application provides an extravasation fluid collection device, which comprises a mounting mechanism 1, a drainage bag 2 and a drainage tube 3. Wherein, referring to Figure 2 and Figure 3 , the mounting mechanism 1 comprises a first collection plate 11, a second collection plate 12, a clasp ring 13 and an air bag 14. The first collection plate 11 and the second collection plate 12 form a sealed conical cover by simple splicing, the conical cover covers the incision of the patient with the drainage tube 4 inserted, the second end of the conical cover is closely combined with the skin of the patient, the conical cover is used for collecting the drainage fluid leaking from the gap between the incision and the outer wall of the drainage tube 4, and the drainage fluid is prevented from polluting clothes, sheets, bedclothes and the like. The drainage tube 4 is connected with the drainage bag 2, and the drainage fluid is guided into the drainage bag 2 through the drainage tube 4. The end face of the first end of the conical cover is provided with a through hole 15 and an annular groove 16, and the clasp ring 13 is sleeved in the annular groove 16. When the conical cover is installed, the first collection plate 11 and the second collection plate 12 clamp the original drainage tube 4, and the first collection plate 11 and the second collection plate 12 are spliced into a conical cover, without the need to pull out the drainage tube 4 from the conical cover and insert it into a replaced conical cover, so that the situation that the outlet end of the drainage tube 4 leaks liquid and dirties the replaced conical cover when passing through the conical cover is avoided. The first end of the spliced conical cover is reinforced by the clasp ring 13, so that the gap between the first collection plate 11 and the second collection plate 12 does not occur, and the situation that the liquid leaks is avoided. The drainage tube 4 is sleeved in the through hole 15, and there is a gap between the drainage tube 4 and the inner wall of the through hole 15, and the air bag 14 is arranged in the gap. The outer wall of the drainage tube 4 and the inner wall of the through hole 15 on the conical cover are filled and sealed by the air bag 14, so that the liquid is prevented from leaking. The air bag 14 is made of rubber, and during installation, the un-inflated air bag 14 is placed in the gap, and then the air bag 14 is inflated until the gap is completely filled with the air bag 14, and the first end of the conical cover is not opened by the clasp ring 13, even if the air bag 14 is inflated excessively. When the extravasation fluid collection device is replaced, the reverse operation can be performed, and the operation is simple. The first collection plate 11 is provided with a drainage nozzle 17, the first end of the drainage tube 3 is connected with the drainage nozzle 17, and the second end of the drainage tube 3 is connected with the drainage bag 2. The extravasation fluid collected by the conical cover flows into the drainage bag 2 through the drainage nozzle 17 and the drainage tube 3 for centralized collection, which not only avoids that the extravasation fluid dirties the clothes of the patient, but also effectively records the amount of the extravasation fluid and performs corresponding detection.

[0048] As shown, Figure 4As shown, the extravasation body fluid collection device also includes a fixed adhesive patch, which includes a transparent body 51 and a temperature-sensitive patch 52. The transparent body 51 is connected to the conical cover, and the transparent body 51 is pasted on the patient's skin. The transparent body 51 is preferably in the shape of an elongated strip, and is pasted along the edge of the second end of the conical cover, and the conical cover is pasted on the patient's skin. The hospital's existing indwelling needle patches, catheter fixing patches, etc. can be directly used, and cut according to the contour and size of the second end of the conical cover, which reduces the cost of use and improves the flexibility of the product. The temperature-sensitive patch 52 is arranged between the transparent body 51 and the patient's skin. The temperature-sensitive patch 52 is a simple adhesive thermometer that does not require batteries or other kinetic energy. As long as the temperature reaches the rated temperature of the temperature-sensitive patch 52, the patch will begin to change color to display the current temperature. The temperature-sensing patch 52 is attached to the skin near the patient's wound. By observing the color change on the patch, the skin temperature can be known. The temperature-sensing patch 52 detects the skin temperature at the patient's wound. When an infection occurs, the skin temperature will be higher than normal body temperature. The skin temperature can be used to detect the infection in time and provide treatment as soon as possible.

[0049] like Figure 5 As shown, a circulation groove 6 is formed on the inner wall of the conical cover. The circulation groove 6 is close to the end surface of the second end of the conical cover. Regardless of the patient's posture, as long as the skin at the wound site has a certain inclination, the exuded body fluid can flow along the skin into the circulation groove 6, preventing the exuded body fluid from being retained on the skin surface for a long time, causing skin moisture and infection. The inlet of the diversion nozzle 17 is connected to the circulation groove 6, and the outlet of the diversion nozzle 17 is connected to the outside of the conical cover and to the first end of the diversion tube 3. When the patient changes his posture so that the level of the inlet of the diversion nozzle 17 is lower than the liquid level of the exuded body fluid in the circulation groove 6, the exuded body fluid can be diverted into the drainage bag 2, keeping the conical cover dry.

[0050] like Figure 6As shown, the first side edge of the first collecting plate 11 is detachably connected with the first side edge of the second collecting plate 12, and the second side edge of the first collecting plate 11 is detachably connected with the second side edge of the second collecting plate 12.

The first side edge of the second collecting plate 12 is provided with a plurality of first protrusions 121 distributed along the length direction of the first side edge, and the second side edge of the second collecting plate 12 is provided with a plurality of second protrusions distributed along the length direction of the second side edge. The first protrusions 121 are detachably connected with the first clamping grooves 111 one by one, and the second protrusions are detachably connected with the second clamping grooves one by one. In an embodiment, the inside of the clamping groove is provided with a groove, and the protrusion is provided with an elastic barb, when the protrusion is inserted into the clamping groove, the elastic barb is clamped into the groove, so as to fix the protrusion in the clamping groove, thereby stably splicing the first collecting plate 11 and the second collecting plate 12 together. The first side edge and the second side edge of the first collecting plate 11 are both provided with sealing strips, when the side edges of the first collecting plate 11 and the second collecting plate 12 abut against each other, the side edges are sealed through the sealing strips, thereby avoiding liquid leakage.

[0051] As shown in Figure 4 The clamping ring 13 is provided with a notch, the clamping ring 13 is in the shape of "C", the drainage tube 4 can pass through the notch, when the clamping ring 13 is installed, the drainage tube 4 is directly passed through the notch of the clamping ring 13 and then sleeved in the clamping ring 13, and the clamping ring 13 is inserted into the annular groove 16 and locked. A plurality of limiting blocks 131 are arranged on the end surface outside the annular groove 16 in pairs, so as to avoid that the clamping ring 13 completely enters the annular groove 16, and the limiting blocks 131 can also be used as handles when the clamping ring 13 is disassembled, thereby facilitating the disassembly of the clamping ring 13.

[0052] As shown in Figure 3 The air bag 14 is in the shape of a cylinder after being inflated, so as to be conveniently filled in the gap, the air bag 14 is provided with an inflation port 141, the inflation port 141 is provided with a one-way valve, a medical syringe can be used to inflate the air bag 14, the operation is simple, and the material is easy to obtain.

[0053] For the structure of the drainage bag 2, the application provides two embodiments:

[0054] Embodiment 1, as shown in Figure 1 and Figure 7As shown, the drainage bag 2 includes a transparent bag 21, a liquid inlet tube 22, a liquid discharge tube 23, a cover bag 24 and a plurality of straps 25.

The cover bag 24 is sleeved on the outside of the transparent bag 21, and the straps 25 are connected to the cover bag 24. The cover bag 24 can be tied to the patient's torso or legs through the straps 25, and the transparent bag 21 can be hidden in clothes or pants to avoid embarrassing situations. It is also convenient for patients to carry it out, especially for patients with lifelong catheterization, which can effectively reduce restrictions on patients' activities and improve patients' user experience. Preferably, the bag 24 is made of skin-friendly cotton material to avoid skin abrasion and ulceration caused by prolonged contact with the skin.

[0055] Example 2, as Figure 1 and Figure 8 As shown, the drainage bag 2 includes a transparent bag 21, a liquid inlet tube 22, a liquid discharge tube 23, a cover bag 24 and a plurality of hooks 26. Scale lines are provided on the transparent bag 21 to facilitate observation of the amount of liquid in the transparent bag 21. The liquid inlet tube 22 is provided at the top of the transparent bag 21, and a three-way pipe is connected to the liquid inlet tube 22. The second end of the guide tube 3 and the drainage tube 4 are both connected to the three-way pipe. The liquid discharge tube 23 is provided at the bottom of the transparent bag 21, and a valve is provided on the liquid discharge tube 23. The cover bag 24 is sleeved on the outside of the transparent bag 21, and a strap 25 is connected to the cover bag 24. The cover bag 24 can be hung on the patient's belt through the hook 26, so that the transparent bag 21 can be hidden in the pants to avoid embarrassing situations, while reducing the patient's restraint and improving the patient's comfort. It is also convenient for patients to carry it out, especially for patients with lifelong catheterization, which can effectively reduce the restrictions on the patient's activities and improve the patient's user experience. Preferably, the bag 24 is made of skin-friendly cotton material to avoid skin abrasion and ulceration caused by prolonged contact with the skin.

[0056] The drainage bags 2 in both embodiments 1 and 2 are convenient for patients to carry. The drainage bag 2 in embodiment 1 is more flexible in its installation position, while the drainage bag 2 in embodiment 2 does not restrict the patient, thereby improving comfort. Patients can choose different sets of bags 24 according to their specific conditions.

[0057] The second end of the conical cover is closely attached to the skin of the patient, and the conical cover is used to collect the exudate from the gap between the incision and the outer wall of the drainage tube 4, so as to avoid the exudate from polluting the clothes, quilt cover, bed sheet and the like. When the conical cover is installed, the first collecting plate 11 and the second collecting plate 12 clamp the original drainage tube 4, and the first collecting plate 11 and the second collecting plate 12 are spliced into the conical cover, so that the drainage tube 4 does not need to be pulled out of the conical cover and then inserted into the replaced conical cover, and the situation that the outlet end of the drainage tube 4 penetrates through the conical cover to cause the drainage tube 4 to leak liquid and dirty the replaced conical cover is avoided. The first end of the spliced conical cover is reinforced by the clasp ring 13, so as to avoid the situation that the gap between the first collecting plate 11 and the second collecting plate 12 is caused to leak liquid. The outer wall of the drainage tube 4 and the inner wall of the through hole 15 on the conical cover are filled and sealed by the air bag 14, so as to avoid liquid leakage. After the air bag 14 is inflated, the gap is completely filled, and even if the air bag 14 is inflated excessively, the first end of the conical cover will not be pried open due to the limitation of the clasp ring 13. When the exosmosis body fluid collecting device is replaced, the operation is reversed, and the operation is simple. The exosmosis body fluid collected by the conical cover flows into the drainage bag 2 through the flow guide nozzle 17 and the flow guide tube 3 for centralized collection, so as to avoid that the exosmosis body fluid dirty the clothes of the patient, and the amount of the exosmosis body fluid can be effectively recorded and detected.
