Description

Technical Field

[0001] The present invention belongs to the technical field of puncture and drainage devices, and in particular relates to a puncture and drainage device. Background Art

[0002] When using a traditional puncture and drainage device, it is easy to scratch or stab the patient after the puncture tube is inserted into the body. The patient's protection depends entirely on the technique and concentration of careful operation, but it is still very unsafe to use. In addition, the traditional puncture and drainage device is not convenient for adding medicine or flushing when in use, nor is it convenient to block the drainage tube or puncture tube for protection or adding medicine, etc. It is inconvenient to use, and adding medicine always requires an external pipeline, which is also inconvenient.

[0003] According to a malignant ascites puncture and drainage device disclosed in Chinese patent publication number CN110215547B, it includes a puncture tube, a flowering piece and a drainage tube, wherein the flowering piece is provided with four, and the flowering piece is annularly bonded to the outer circle of the puncture tube, a stopper is fixed on the side of the outer circle of the puncture tube close to the flowering piece, and a sliding sleeve is installed on the side of the stopper away from the flowering piece, and the sliding sleeve is sleeved on the tube body of the puncture tube. The malignant ascites puncture and drainage device has flowering pieces arranged in a ring on the tube body of the puncture tube. When the puncture tube is inserted into the abdomen, the flowering piece can also enter the human body smoothly and can push the sliding sleeve outward so that the sliding sleeve drives the core plate to be completely withdrawn from the core groove. Since the flowering piece is made of shape-memory rubber and the temperature of ascites is the same as that of the human body, the flowering piece rises in memory and deforms into an outward-turned shape after absorbing the temperature, and the elastic deformation of the spring piece assists in rolling up, so that the flowering piece can be stuck in the abdomen, thereby preventing it from falling off due to abdominal contraction and extension when the patient breathes.

[0043] In this embodiment, when the device is in use, the fixing sleeve 125 is separated from the drainage tube 112 by rotating the fixing sleeve 125, and the threaded rod C124 is slid to the left so that the threaded rod C124 drives the baffle 123 to the left, and the baffle 123 drives the puncture needle 121 on the mounting rod 122 to the left, and the puncture needle 121 extends from the drainage tube 112, and the fixing sleeve 125 is rotated on the threaded rod C124, and the fixing sleeve 125 is tightened and fits tightly with the drainage tube 112, thereby fixing the position of the threaded rod C124, thereby fixing the position of the puncture needle 121, and facilitating the puncture operation. After the puncture operation is completed, the drainage tube 112 should also be inserted, and the fixing sleeve 125 is rotated to separate from the drainage tube 112, and the threaded rod C124 is slid to the right so that the baffle 123 drives the mounting rod 122 The puncture needle 121 on the upper part is retracted to the right into the drainage tube 112, and drainage operation is performed through the drainage tube 112 to prevent the puncture needle 121 from piercing other positions, thereby improving the safety of the drainage operation of the device, improving the convenience of the drainage operation of the device, and protecting the patient. The drainage liquid enters the drainage tube 112 through the puncture needle 121, and the baffle 123 closes the movable groove of the drainage tube 112 to prevent the drainage liquid from flowing out of the movable groove. The liquid enters the piston tube 111. At this time, the pump 16 runs through the discharge pipe 151 to discharge the waste liquid in the piston tube 111. After the drainage is completed, the threaded rod A153 should be rotated to drive the pressure rod 154 to compress and deform the discharge tube 151 and then close it, so that the discharge tube 151 will no longer flow out or flow into the liquid, and the drainage operation is performed. When the drainage operation is completed, the position of the drainage tube 112 is moved, and the waste liquid remaining in the patient's body is manually sucked out to ensure that it is clean.

Then, the threaded rod B174 is rotated to separate the closing block 175 from the output end of the shunt tube 172. Then, the pipe plug 135 is moved to the left to close the drainage tube 112 and the position of the connecting rod B134 is fixed by hand. Then, the bracket 137 is pulled to the right. The negative pressure causes the flushing liquid and other medicines in the placement box 183 to flow from the puncture head 181 into the shunt tube 172 through the connecting tube 182, and then flows into the piston tube 111 through the shunt tube 172. Then, the pipe plug 135 is moved to the right to separate from the drainage tube 112.When the bottle is not in use, the output end of the shunt tube 172 can be closed by rotating the threaded rod B174. When the connecting window 173 is seriously damaged, the shunt tube 172 can be unscrewed from the mounting seat 171, and a new shunt tube 172 can be replaced and screwed into the mounting seat 171. When adding medicine, pull the bracket 137 to the right, and then pass the needle of the syringe through the dosing window 142 in the limit seat 141 and inject it into the piston tube 111. The medicine is injected into the drainage tube 112 through the piston block 132. When the device is not in use, the pipe plug 135 should be inserted into the drainage tube 112 to seal and store the drainage tube 112, thereby improving the drainage effect of the device, improving the convenience of flushing the device, facilitating the dosing of the device, and facilitating the storage of the device. The small amount of residual waste liquid can be absorbed more completely, and the drainage tube 112 can be moved to avoid scratching or stabbing the patient, thereby improving the safety of the device. ,

[0051] In this embodiment: In combination with the above, after the drainage is completed, the threaded rod A153 should be rotated to drive the pressure rod 154 to compress and deform the discharge pipe 151 and then close it, so that the discharge pipe 151 will no longer flow out or flow into the liquid. When performing the drainage operation, the connecting rod B134 should be pulled to the right to make the shift block 136 fit with the bracket 137, and then the pipe plug 135 is separated from the drainage pipe 112. The synchronous block 138 is rotated to limit the shift block 136.

The bracket 137 is pushed to the left so that the piston block 132 presses the flushing liquid into the area to be flushed and then draws it out. When not in use, the output end of the shunt tube 172 can be closed by rotating the threaded rod B174. When the connecting window 173 is severely worn, the shunt tube 172 can be unscrewed from the mounting seat 171, and a new shunt tube 172 can be replaced and screwed into the mounting seat 171.

[0063] The working principle and use process of the present invention are as follows: when the device is in use, the fixing sleeve 125 is separated from the drainage tube 112 by rotating the fixing sleeve 125, and the threaded rod C124 is slid to the left so that the threaded rod C124 drives the baffle 123 to the left, and the baffle 123 drives the puncture needle 121 on the mounting rod 122 to the left, and the puncture needle 121 extends from the drainage tube 112, and the fixing sleeve 125 is rotated on the threaded rod C124, and the fixing sleeve 125 is tightened to fit tightly with the drainage tube 112, thereby fixing the position of the threaded rod C124, thereby fixing the position of the puncture needle 121, and facilitating the puncture operation. After the puncture operation is completed, the drainage tube 112 should also be inserted, and the fixing sleeve 125 is rotated to separate from the drainage tube 112, and the threaded rod C124 is slid to the right so that the baffle 1 23 drives the puncture needle 121 on the mounting rod 122 to the right and retracts it into the drainage tube 112. Drainage is performed through the drainage tube 112 to prevent the puncture needle 121 from piercing other positions, thereby improving the safety of the drainage operation of the device and the convenience of the drainage operation of the device, and protecting the patient. The drainage liquid enters the drainage tube 112 through the puncture needle 121, and the baffle 123 seals the movable groove of the drainage tube 112 to prevent the drainage liquid from flowing out of the movable groove. The liquid enters the piston tube 111. At this time, the pump 16 runs through the discharge pipe 151 to discharge the waste liquid in the piston tube 111. After the drainage is completed, the threaded rod A153 should be rotated to drive the pressure rod 154 to compress and deform the discharge tube 151 and then seal it, so that the discharge tube 151 will no longer flow out or The patient then has to move the piston 132 to the top of the drain tube 112, and the piston 132 and the pipe plug 135 are in contact with each other to seal the connection between the pipe 133 and the drain tube 112. When the drainage operation is completed, the position of the drainage tube 112 is moved, and the waste liquid remaining in the patient's body is manually sucked out to ensure that it is clean. Then the bracket 137 can be pulled to drive the connecting rod A131 to the right, and the piston block 132 is moved to the top of the drain tube 112 to seal the connection between the pipe 133 and the drain tube 112. The right side generates negative pressure in the piston tube 111, and then the waste liquid is sucked out through the drainage tube 112. The discharge tube 151 should also be closed during manual suction. After the liquid to be flushed is poured into the placement box 183, the puncture head 181 pierces the connecting window 173 to connect the connecting tube 182 with any input end of the shunt tube 172, and then the threaded rod B174 is rotated to separate the closing block 175 from the output end of the shunt tube 172. Then the pipe plug 135 is moved to the left to close the drainage tube 112 and the position of the connecting rod B134 is fixed by hand. Then, the bracket 137 is pulled to the right. The negative pressure causes the flushing liquid and other medicines in the placement box 183 to flow from the puncture head 181 into the shunt tube 172 through the connecting tube 182, and then into the piston tube 111 through the shunt tube 172.Then, the right pipe plug 135 is separated from the drainage tube 112, and the bracket 137 is pushed to the left, so that the piston block 132 presses the flushing liquid into the part to be flushed, and then withdraws it. When not in use, the output end of the shunt tube 172 can be closed by rotating the threaded rod B174. When the connecting window 173 is seriously worn, the shunt tube 172 can be unscrewed from the mounting seat 171, and a new shunt tube 172 can be replaced by screwing it into the mounting seat 171. When adding medicine, pull the bracket 137 to the right, and then pass the needle of the syringe through it. The dosing window 142 in the limiting seat 141 can be injected into the piston tube 111, and the liquid medicine is injected through the drainage tube 112 through the piston block 132. When the device is not in use, the pipe plug 135 should be inserted into the drainage tube 112 to seal the drainage tube 112. This improves the drainage effect of the device, improves the convenience of flushing the device, facilitates the dosing of the device, and facilitates the storage of the device. The remaining small amount of waste liquid can be more completely absorbed. The drainage tube 112 can be moved to avoid scratching or puncturing the patient, thereby improving the safety of the device.
