Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical appliances, and particularly to a double-bag anchor-flow anti-seepage flushing cannula. Background Art
[0002] After abdominal surgery, an abdominal drainage tube is routinely indwelled. The purpose is to drain the accumulated fluid in the abdominal cavity (such as blood, pus, ascites, etc.) through physical means, prevent postoperative infection, reduce toxin absorption, and at the same time monitor the characteristics of the drainage fluid and detect postoperative complications such as bleeding, infection, and anastomotic leakage at an early stage, so as to promote the recovery of the patient.
[0003] At present, the following technical defects exist in the drainage tubes clinically: The catheter is not easy to fix, and the incidence of unplanned extubation is high: The traditional drainage tube is fixed to the skin by silk suture ligation. The operation is troublesome, and the skin at the suture ligation site has obvious pain and discomfort; the silk is smooth, and the knot is easy to loosen. If the drainage tube is indwelled for too long or the exudate is too much, the suture will fall off or lose friction, and the catheter cannot be effectively fixed. Clinically, in order to prevent the catheter from slipping, tape is used for secondary fixation. However, the adhesion of the tape is insufficient or the proximal end can only be fixed on the dressing. After surgical dressing change, the tape needs to be replaced, increasing the workload of nurses and the cost of consumables; there are various existing skin external fixation devices. However, if the exudate at the drainage orifice exceeds the absorbable amount of the device, the whole set of devices needs to be disassembled during dressing change, and it is even more troublesome to fix the catheter again.
[0004] The catheter is soft and easy to bend, and the drainage fluid oozes out from the skin puncture hole, increasing the frequency of dressing change and the risk of retrograde infection: The existing solution is to use a ostomy bag to catch the exudate. The drainage tube can be removed or cut short, and the cut short drainage tube can be put into the ostomy bag, and then the ostomy bag is directly adhered to the skin puncture hole. This method maintains the integrity of the ostomy bag, but there is a risk of drainage fluid backflow; it is also possible to pass the drainage tube through the ostomy bag, maintaining the complete drainage of the drainage tube, but destroying the integrity of the ostomy bag, and there is still a risk of drainage fluid leakage.
[0005] The catheter cannot directly extract the drainage fluid for testing: Usually, a needle is used to pierce the drainage bag or the drainage tube, destroying the airtightness of the catheter or requiring a new replacement of the drainage bag, increasing the workload of medical staff. If the operation is improper, the risk of retrograde infection will increase.
[0006] The drainage tube is prone to blockage and lacks a flushing function, resulting in low drainage efficiency: Blood clots, necrotic tissue or fibrin deposition may cause the pipeline to block, and frequent squeezing is required, increasing the nursing burden and the squeezing may not be effective. After abdominal surgery, complications such as enterocutaneous fistula, pancreatic fistula, and abdominal abscess occur, and abdominal irrigation is required. If a double cannula is not placed in advance during the operation, a disposable scalp needle, an extension tube and a transparent dressing need to be used temporarily at the bedside after the operation. If the operation is not careful, a needlestick injury may occur when the disposable scalp needle punctures the drainage tube, and at the same time, the risk of retrograde infection increases. Summary of the Invention
[0007] The object of the present invention is to provide a double - capsule anchor - flow anti - leakage flushing cannula, which clamps the abdominal wall of the patient through the inner abdominal capsule and the outer abdominal capsule, so as to achieve the purpose of sealing the skin puncture hole and fixing the flushing cannula, improve the comfort of the patient and reduce the probability of leakage from the puncture hole. Medical staff do not need to suture the skin puncture hole and additionally apply a stoma bag. The inner abdominal capsule also plays a role in compressing and stopping bleeding, reducing the probability of secondary surgery.
[0008] In order to achieve the above - mentioned invention object, the present invention adopts the following technical solutions: A double - capsule anchor - flow anti - leakage flushing cannula includes an inner abdominal tube and an outer abdominal tube. One end of the inner abdominal tube is connected to one end of the outer abdominal tube and integrally formed. The other end of the inner abdominal tube is provided with an inner abdominal orifice, and the other end of the outer abdominal tube is provided with an outer abdominal orifice. An existing drainage bag pagoda joint is inserted into the outer abdominal orifice. The inner abdominal tube is inserted into the abdominal cavity through the skin puncture hole of the patient, and the outer abdominal capsule exposes outside the body through the skin puncture hole of the patient. An inner abdominal capsule and an outer abdominal capsule are provided at the connection of the inner abdominal tube and the outer abdominal tube. The inner abdominal capsule is arranged on the outer peripheral surface of the inner abdominal tube and surrounds it in a circle. The outer abdominal capsule is arranged on the outer peripheral surface of the outer abdominal tube and surrounds it in a circle. An A inflatable joint for inflating and deflating the inner abdominal capsule and a B inflatable joint for inflating and deflating the outer abdominal capsule are provided outside the outer abdominal tube. The A inflatable joint is communicated with the inner abdominal capsule, and the B inflatable joint is communicated with the outer abdominal capsule: when the A inflatable joint and the B inflatable joint are respectively inflated, the abdominal wall of the patient is clamped between the inner abdominal capsule and the outer abdominal capsule, and the skin puncture hole of the patient is sealed.
[0009] Compared with the prior art, the double - capsule anchor - flow anti - leakage flushing cannula adopting the above - mentioned technical solutions has the following beneficial effects: When using the double - capsule anchor - flow anti - leakage flushing cannula of the present invention, medical staff insert the inner abdominal tube into the abdominal cavity through the skin puncture hole of the patient, inflate the inner abdominal capsule through the A inflatable joint, and inflate the outer abdominal capsule through the B inflatable joint, so that the inner abdominal capsule and the outer abdominal capsule clamp the abdominal wall of the patient. The pressure of the inner abdominal capsule and the outer abdominal capsule can be adjusted according to needs, so as to achieve the purpose of sealing the skin puncture hole and fixing the flushing cannula. Medical staff do not need to suture around the skin puncture hole to fix the flushing cannula, which improves the comfort of the patient, and the flushing cannula in the skin puncture hole has better firmness and is easy to operate.
[0010] Medical staff can connect an existing Covidien air - filled balloon manometer (manufacturer: Guangxi Nanning Demai Medical Equipment Co., Ltd.) to the A inflatable joint, and inflate and deflate the inner abdominal capsule according to needs, so as to adjust the pressure of the inner abdominal capsule, play a role in compressing and stopping bleeding of the abdominal wall caused by the puncture hole, and reduce the probability of secondary surgery.
[0011] The outer abdominal capsule has a shaping function, which can ensure unobstructed drainage and prevent the flushing cannula from being compressed and distorted.
[0012] The external abdominal sac and the internal abdominal sac are respectively closely attached to the abdominal wall, with better sealing performance, reducing the probability of abdominal cavity fluid leaking out around the puncture hole and reducing the number of dressing changes by medical staff. Medical staff do not need to additionally attach a stoma bag around the skin puncture hole to collect the exudate, reducing the economic burden on patients using the stoma bag; In the preferred embodiment, the outer end of the auxiliary tube can optionally be connected to an infusion set and a syringe. When using the infusion set, the purpose of abdominal cavity irrigation and preventing tube blockage can be achieved through the irrigation channel, without using a disposable scalp needle to puncture the irrigation cannula as in the prior art, avoiding needle stick injuries and retrograde infections; when using the syringe, drainage fluid specimens can be collected for laboratory tests, without piercing the irrigation cannula or the drainage bag with a needle, avoiding contamination and damage to the drainage bag and reducing the workload of medical staff.

The C inflation connector is communicated with the shock wall sac: when the C inflation connector injects gas, the shock wall sac expands to reduce the inner diameter of the internal abdominal tube; when the C inflation connector deflates, the shock wall sac contracts to increase the inner diameter of the internal abdominal tube. By repeatedly inflating and deflating the shock wall sac through the C inflation connector, the inner diameter of the internal abdominal tube can be reduced and enlarged, allowing pulsed air flow to be introduced, rapidly changing the inner diameter of the internal abdominal tube, achieving a vibration effect and reducing the occurrence of tube blockage.
[0017] Preferably, three gas delivery tubes are provided on the outer wall of the external abdominal tube.

Detailed Description of the Invention
[0027] To further illustrate the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following combines the drawings and preferred embodiments to detail the specific implementation manners, structures, features and their effects of the present invention as follows.
[0028] As Figures 1 to 6The double-capsule anchor-flow anti-seepage flushing cannula shown in the figure includes an inner abdominal tube 1 and an outer abdominal tube 2. One end of the inner abdominal tube 1 is connected to and integrally formed with one end of the outer abdominal tube 2. The other end of the inner abdominal tube 1 is provided with an inner abdominal opening 10, and the other end of the outer abdominal tube 2 is provided with an outer abdominal opening 20. A pagoda joint 51 of an existing drainage bag 5 is inserted into the outer abdominal opening 20. The inner abdominal tube 1 is inserted into the abdominal cavity 60 through a skin puncture hole 61 of the patient, and the outer capsule 21 is exposed outside the body through the skin puncture hole 61 of the patient. An inner abdominal capsule 11 and an outer abdominal capsule 21 are provided at the connection of the inner abdominal tube 1 and the outer abdominal tube 2. The inner abdominal capsule 11 is provided on the outer peripheral surface of the inner abdominal tube 1 and is arranged in a circle. The outer abdominal capsule 21 is provided on the outer peripheral surface of the outer abdominal tube 2 and is arranged in a circle. An A inflation joint 41 and a B inflation joint 42 are provided outside the outer abdominal tube 2. The A inflation joint 41 is communicated with the inner abdominal capsule 11, and the B inflation joint 42 is communicated with the outer abdominal capsule 21: When the A inflation joint 41 and the B inflation joint 42 are inflated respectively, the abdominal wall 6 of the patient is clamped between the inner abdominal capsule 11 and the outer abdominal capsule 21, and the skin puncture hole 61 of the patient is blocked. Medical staff insert the inner abdominal tube 1 into the abdominal cavity 60 through the skin puncture hole 61 of the patient, inflate the inner abdominal capsule 11 through the A inflation joint 41, and inflate the outer abdominal capsule 21 through the B inflation joint 42, so that the inner abdominal capsule 11 and the outer abdominal capsule 21 clamp the abdominal wall 6 of the patient. The pressure of the inner abdominal capsule 11 and the pressure of the outer abdominal capsule 21 can be adjusted according to needs, so as to achieve the purpose of blocking the skin puncture hole 61 and fixing the flushing cannula. Medical staff do not need to suture around the skin puncture hole 61 to fix the flushing cannula, which improves the comfort of the patient, and the flushing cannula in the skin puncture hole 61 has better firmness and is easy to operate.
[0029] Among them, medical staff can connect an existing Covidien balloon pressure gauge (manufactured by Guangxi Nanning Demai Medical Equipment Co., Ltd.) to the A inflation joint 41, and inflate and deflate the inner abdominal capsule 11 according to needs, so as to adjust the pressure of the inner abdominal capsule 11, play a role in compressing and stopping bleeding of the abdominal wall caused by the puncture hole, and reduce the probability of secondary surgery. The outer abdominal capsule 21 has a shaping function, can ensure unobstructed drainage, and prevent the flushing cannula from being compressed and twisted. The outer abdominal capsule 21 and the inner abdominal capsule 11 are respectively closely attached to the abdominal wall 6, with better sealing performance, reducing the probability of liquid in the abdominal cavity 60 seeping out from around the puncture hole, and reducing the number of dressing changes by medical staff. Medical staff do not need to additionally stick a stoma bag around the skin puncture hole 61 to collect exudate, reducing the economic burden of the patient using the stoma bag.
[0030] Refer to Figure 1 and Figure 4, the inner wall of the abdominal tube 1 is provided with a flushing channel 13. The length direction of the flushing channel 13 is the same as that of the abdominal tube 1. One end of the flushing channel 13 close to the abdominal opening 10 is provided with a channel opening 14. The outer wall of the abdominal external tube 2 is provided with a secondary tube 22, and the outer end of the secondary tube 22 is provided with a docking head 23. The docking head 23 at the outer end of the secondary tube 22 can be selectively connected to an infusion device and a suction device. When using the infusion device, the purpose of abdominal cavity 60 flushing and preventing tube blockage can be achieved through the flushing channel 13, without using the existing disposable scalp needle to puncture the flushing cannula, avoiding needle stick injuries and retrograde infections; when using the suction device, drainage fluid specimens can be collected for laboratory tests, without using a needle to pierce the flushing cannula or the drainage bag 5, avoiding contamination and damage to the drainage bag 5 and reducing the workload of medical staff.
[0031] Among them, the docking head 23 adopts a Luer connector. The Luer connector has better sealing performance and stable connection, reducing the risk of infection.
[0032] Refer to Figures 4 to 6 , a plurality of flushing holes 15 are provided on the peripheral surface of the flushing channel 13. The inner wall of the abdominal tube 1 can be flushed through the plurality of flushing holes 15, reducing the occurrence of tube blockage.
[0033] Among them, a plurality of drainage holes 12 are provided on the peripheral surface of the abdominal tube 1, increasing the drainage effect through the plurality of drainage holes 12.
[0034] Among them, a vibration wall bladder 3 is provided on the inner wall of the abdominal tube 1. The vibration wall bladder 3 is in a "C" shape. The vibration wall bladder 3 is provided with a through hole 30 at the same position as the flushing hole 15. An external C inflation joint 43 is provided outside the abdominal external tube 2, and the external C inflation joint 43 is communicated with the vibration wall bladder 3: when the external C inflation joint 43 injects gas, the vibration wall bladder 3 expands to reduce the inner diameter of the abdominal tube 1; when the external C inflation joint 43 deflates, the vibration wall bladder 3 contracts to increase the inner diameter of the abdominal tube 1. By repeatedly inflating and deflating the vibration wall bladder 3 through the external C inflation joint 43, the inner diameter of the abdominal tube 1 can be reduced and enlarged, pulse airflow can be introduced, the inner diameter of the abdominal tube 1 can be rapidly changed, achieving a vibration effect, reducing the occurrence of tube blockage, and preventing blood clots, tissues and mucus from blocking the flushing holes 15.
[0035] Refer to Figure 1 , three air delivery tubes 40 are provided on the outer wall of the abdominal external tube 2. The air delivery tubes 40 are made of flexible tubes. An A inflation joint 41, a B inflation joint 42 and an external C inflation joint 43 are respectively provided at the outer ends of the three air delivery tubes 40. The A inflation joint 41, the B inflation joint 42 and the external C inflation joint 43 are respectively of different colors. The A inflation joint 41 is marked with the word "inner bladder", the B inflation joint 42 is marked with the word "outer bladder", and the external C inflation joint 43 is marked with the word "extrusion bladder", which is convenient for medical staff to distinguish. Medical staff can inflate, deflate or measure pressure separately according to needs.
[0036] Among them, an integrated pipe 4 is provided on the outer wall of the external abdominal pipe 2, and all three gas delivery pipes 40 are arranged inside the integrated pipe 4. The three gas delivery pipes 40 are concentrated together through the integrated pipe 4, which is convenient for cutting the integrated pipe 4 during tube extraction, allowing the external abdominal bladder 21, the internal abdominal bladder 11, and the shock wall bladder 3 to deflate simultaneously, further improving work efficiency.
[0037] Among them, the length of the internal abdominal pipe 1 is greater than the length of the flushing channel 13 to prevent tissue damage and bleeding in the abdominal cavity 60 caused by excessive pressure during flushing + negative pressure drainage. The internal abdominal pipe 1 is relatively long, and a length scale bar is marked on the outer wall of the internal abdominal pipe 1. Medical staff can cut the length of the internal abdominal pipe 1 according to requirements to suit different patients and different surgical site placement scenarios.
[0038] The thickness of the adult abdominal wall 6 is generally 1.5 - 4 cm, and the abdominal wall 6 of obese patients will be more than 5 cm. Given that the thickness, puncture hole depth, and size of each patient's abdominal wall 6 are different, medical staff can choose whether to use the external abdominal bladder 21 according to requirements: If the length of the internal abdominal bladder 11 is much greater than the thickness of the patient's abdominal wall 6, a part of the internal abdominal bladder 11 is inside the skin puncture hole 61, and another part is inside the abdominal cavity 60. The internal abdominal bladder 11 is inflated through the A inflation connector 41. A part of the internal abdominal bladder 11 presses against the inner wall of the puncture hole 61, and another part presses against the inner surface of the abdominal wall 6, playing a role in blocking the puncture hole 61 and compressing to stop bleeding. Even if the external abdominal bladder 21 is not inflated, the flushing cannula is not easily bent; on the contrary, it is still necessary to inflate the external abdominal bladder 21 through the B inflation connector 42. The external abdominal bladder 21 presses against the outer surface of the abdominal wall 6, so that the abdominal wall 6 is clamped between the internal abdominal bladder 11 and the external abdominal bladder 21, increasing the blocking effect and improving firmness.
[0039] The above are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
