[0002] A puncture procedure refers to the use of a puncture needle to penetrate into a body cavity to extract fluid for further testing, or to inject certain chemicals or air into the body cavity. It is widely used clinically as a treatment or examination method.

[0003] After the puncture operation is completed and the PICC catheter is removed, the wound at the puncture site still needs some time to recover and maintain. However, at present, the patient may have exudation at the puncture site due to the failure to drain the intracavitary fluid cleanly. Although the incidence of exudation is only 2.21%, once it occurs, it will not only bring discomfort and pain to the patient, but even endanger his life in severe cases. It will also cause trouble to the nursing staff, affect the nurse-patient relationship, increase the medical burden, and interfere with the orderly progress of the subsequent nursing work.

[0004] Currently, the nursing operation for exudate at the puncture point is to repeatedly absorb it with gauze, which is cumbersome and inefficient, and the amount of exudate cannot be known. The puncture point is fixed with adhesive tape, which is repeatedly torn and stuck, which also causes damage to the skin. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] like Figure 1-6 As shown, the utility model provides a technical solution: a medical puncture point exudate collection device, comprising a fastening belt 1 sleeved outside the patient's limb, a Velcro hook surface 14 is fixed to the outer periphery of one end of the fastening belt 1, and a Velcro fur surface 15 matching the Velcro hook surface 14 is fixed to the other end facing the Velcro hook surface 14. After the fastening belt 1 is sleeved outside the patient's limb and fits tightly with the patient's limb, the Velcro fur surface 15 is made to contact and fit with the Velcro hook surface 14, thereby fixing the position of the fastening belt 1, without the need to use glue to stick it on the patient's skin, reducing the impact of the adhesive on the patient's skin, and improving the patient's comfort and safety.

[0035] like Figure 1 and Figure 2 and Figure 4 As shown in the figure, a ring 2 that contacts the patient's skin and covers the puncture point is fixed to the side of the fastening belt 1 facing the patient's puncture point, a rubber ring is fixed to the side of the ring 2 facing the patient's skin, and a connector 3 that is connected to the inner cavity of the ring 2 is integrally formed on the side of the ring 2 away from the patient's skin. The connector 3 passes through the fastening belt 1 and is fixed to the fastening belt 1. The part of the connector 3 that passes through the fastening belt 1 is tightly connected with a drainage tube 4 connected to the connector 3, and a liquid collection bag 5 that is connected to the drainage tube 4 and is used to collect exudate is fixed to the end of the drainage tube 4 away from the connector 3.

[0036] like Figure 1 and Figure 2 and Figure 4The fastening belt 1 is sleeved on the outside of the patient's limb and fully fits with the patient's limb, so that the patch ring 2 can fully fit with the patient's skin, and the exudate at the puncture point will not leak from the gap between the patch ring 2 and the patient's skin, nor will it wet the patient's clothes, thereby improving the patient's comfort. The gap between the patch ring 2 and the patient's skin is connected to the inner cavity of the connector 3, and the inner cavity of the connector 3 is connected to the drainage tube 4 and the liquid collection bag 5. The exudate at the puncture point will enter the connector 3 and the drainage tube 4 and be collected by the liquid collection bag 5, which is convenient for observing the amount of exudate. By setting a rubber ring, the possibility of the exudate at the puncture point overflowing from the gap between the patch ring 2 and the patient's skin is further reduced.

[0037] like Figure 2 and Figure 3 A plug 6 is fixed to one end of the drainage tube 4 away from the liquid collection bag 5, and a slot 7 connected to the inner cavity of the connector 3 is opened on the side of the connector 3 facing the plug 6. A rubber sealing ring is fixed to the inner wall of the slot 7. The drainage tube 4 is inserted into the inner cavity of the connector 3 through the plug 6 and is tightly connected with the connector 3 to be fixed. The connector 3 and the drainage tube 4 are fixedly connected by a connecting assembly.

[0038] like Figure 2 and Figure 3 The plug 6 is inserted into the inner cavity slot 7 of the connector 3 and is tightly connected with the connector 3. The rubber sealing ring is deformed under pressure to close the gap between the plug 6 and the connector 3. The liquid will not leak out from the gap between the plug 6 and the connector 3. The drainage tube 4 is fixedly connected to the connector 3 through the cooperation of the plug 6 and the slot 7. The connector 3, the plug 6 and the drainage tube 4 are interconnected. By arranging a connecting component on the drainage tube 4 and the connector 3, the possibility of the drainage tube 4 falling off from the connector 3 due to accidental touching by the patient turning over is reduced.

[0039] like Figure 2 and Figure 3 The connecting component includes an A annular groove 8 opened in the part of the connecting head 3 that passes through the fastening belt 1, an annular block 9 is integrally formed on the circumferential outer wall of the drainage tube 4, a B annular groove 10 is opened on the circumferential outer wall of the annular block 9, an A claw 11 that is tightly connected to the A annular groove 8 is sleeved on the A annular groove 8, and a B claw 12 that is tightly connected to the B annular groove 10 is sleeved on the B annular groove 10, and the A claw 11 and the B claw 12 are integrally formed through a connecting rod 13.

[0040] like Figure 2 and Figure 3The A claw 11 and the B claw 12 are elastic. When the plug 6 is inserted into the slot 7 of the connector 3, the staff grasps the connecting rod 13, and the A claw 11 is sleeved outside the A annular groove 8 and is tightly connected to the A annular groove 8, and the B claw 12 is sleeved outside the B annular groove 10 and is tightly connected to the B annular groove 10. At this time, even if the patient turns over or accidentally touches the drainage tube 4, the drainage tube 4 will not be pulled out from the connector 3 and pull the wound, which will not affect the wound contraction function, thereby improving the safety of the device.

[0041] like Figure 1 and Figure 2 and Figure 3 and Figure 4 A ring-shaped airbag 16 located beside the adhesive ring 2 is fixed on the fastening belt 1, and the ring-shaped airbag 16 passes through the fastening belt 1. The side of the ring-shaped airbag 16 facing the patient's skin is in contact with the annular skin. A connecting tube 17 connected to the inner cavity of the ring-shaped airbag 16 is fixed on the side of the ring-shaped airbag 16 away from the annular skin. One end of the connecting tube 17 away from the annular airbag 16 is connected to the air outlet of the micro air pump through a pipeline.

[0042] like Figure 1 and Figure 2 and Figure 3 and Figure 4 The micro air pump provides power, and the annular airbag 16 is inflated and enlarged, completely fitting with the patient's skin while moderately squeezing the puncture point, closing the capillary lymphatic vessels without closing the capillaries, not affecting the blood supply of the tissue, and at the same time playing a role of compression and hemostasis.

[0043] like Figure 1 and Figure 5 and Figure 6 The drainage tube 4 is provided with an anti-backflow component to reduce the possibility of liquid flowing back into the drainage tube 4 and contacting the patient's skin. By setting the anti-backflow component, the possibility of liquid in the liquid collection bag 5 flowing back into the drainage tube 4 due to squeezing and affecting the patient is reduced.

[0044] like Figure 5 and Figure 6The backflow prevention component includes a fixed tube 18 fixed on the inner cavity groove wall of the drainage tube 4, an annular plate 19 whose center line coincides with the center line of the fixed tube 18 is integrally formed on the inner cavity groove wall of the fixed tube 18, a fixed plate 21 is integrally formed at the middle position inside the fixed tube 18 through a support rod 20, the center line of the fixed plate 21 coincides with the center line of the fixed tube 18, a circular groove 22 is opened at the middle position of the fixed plate 21, a guide rod 23 is penetrated in the circular groove 22 and is slidably connected to the circular groove 22, an arc-shaped baffle 24 is fixed to one end of the guide rod 23 toward the fastening belt 1, and the arc-shaped baffle 24 closes the inner cavity of the fixed tube 18 when it moves to conflict with the annular plate 19, the arc-shaped baffle 24 is fixed to the fixed plate 21 by a spring 25 sleeved on the outside of the guide rod 23, and a support plate 26 for limiting the position of the arc-shaped baffle 24 is fixed on the fixed plate 21.

[0045] like Figure 5 and Figure 6 The position of the arc baffle 24 is limited by the spring 25, and the position of the arc baffle 24 is limited by the arc block. When the liquid flows back, the arc baffle 24 moves to contact the annular plate 19, closing the inner cavity of the fixed tube 18. When the liquid flows normally, the arc baffle 24 moves under pressure, and the spring 25 is compressed. The liquid enters the liquid collection bag 5 through the gap between the annular plate 19, the arc baffle 24 and the fixed tube 18, without affecting the liquid collection.

[0046] like Figure 5 and Figure 6 A rubber sealing ring is fixed on the side of the annular plate 19 facing the arc baffle 24 to improve the sealing performance between the annular plate 19 and the arc baffle 24. When the annular plate 19 contacts the arc baffle 24, the rubber sealing ring is compressed and deformed, filling the gap between the annular plate 19 and the arc baffle 24 to play a sealing role.

[0047] When in use, the staff puts the fastening belt 1 on the outside of the limb of the patient's puncture point and makes it fit completely with the patient's limb. At the same time, the patch ring 2 covers the patient's puncture point. The fastening belt 1 is firmly fitted with the Velcro hook surface 14 through the Velcro fur surface 15, thereby fixing the position of the fastening belt 1, so that the patch ring 2 is completely fitted with the patient's skin, and there is no possibility that the exudate from the puncture point will overflow from the gap between the patch ring 2 and the patient's skin. No adhesive is used to stick on the patient's skin, which reduces the impact of the adhesive on the patient's skin and improves the patient's comfort and safety.

[0048] The plug 6 is inserted into the inner cavity slot 7 of the connector 3 and is plugged and connected with the connector 3. The rubber sealing ring is deformed under pressure to close the gap between the plug 6 and the connector 3. Liquid will not leak out from the gap between the plug 6 and the connector 3. The drainage tube 4 is fixedly connected to the connector 3 through the cooperation of the plug 6 and the slot 7. At this time, the patch ring 2, the connector 3, the drainage tube 4 and the liquid collection bag 5 are fixedly connected and interconnected. The exudate from the puncture point will enter the connector 3 and the drainage tube 4 and be collected by the liquid collection bag 5, which is convenient for observing the amount of exudate and reduces the impact of the exudate on the patient.

[0049] Then, the connecting rod 13 is grasped, and the A clamping claw 11 is sleeved outside the A annular clamping groove 8 and is clamped and connected with the A annular clamping groove 8, and the B clamping claw 12 is sleeved outside the B annular clamping groove 10 and is clamped and connected with the B annular clamping groove 10. At this time, even if the patient turns over or touches the drainage tube 4 by mistake, the drainage tube 4 will not be pulled out from the connecting head 3 and pull the wound, which will not affect the wound contraction function, thereby improving the safety of the device;

[0050] At the same time, the air outlet of the micro air pump is fixedly connected to the air inlet of the connecting tube 17, and the micro air pump is turned on. The micro air pump provides power, and the annular air bag 16 is inflated and enlarged, and is completely attached to the patient's skin while appropriately squeezing the puncture point, pressing and closing the capillary lymphatic vessels without closing the capillaries, and not affecting the blood supply of the tissue, and at the same time playing a role of compression and hemostasis;

[0051] When the liquid enters the liquid collecting bag 5 through the drainage tube 4, the liquid pressure pushes the arc baffle 24 to move. The movement of the arc baffle 24 will drive the guide rod 23 fixed to the arc baffle 24 to move, and the spring 25 is compressed until the arc baffle 24 conflicts with the support plate 26. At this time, the liquid enters the liquid collecting bag 5 through the gap between the annular plate 19, the arc baffle 24, the fixed tube 18, the fixed plate 21 and the support rod 20, without affecting the liquid collection. When the liquid collecting bag 5 is pressurized and the liquid flows back into the drainage tube 4, the arc baffle 24 moves under the push of the liquid to conflict with the annular plate 19, the spring 25 rebounds, and the arc baffle 24 closes the gap between the fixed tube 18 and the annular plate 19. At this time, the liquid cannot enter the drainage tube 4 and affect the patient, thereby improving the safety and stability of the device. This is the use process of the medical puncture point exudate collection device. At the same time, the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
