Description

Technical Field

[0001] The utility model relates to the field of medical technology, in particular to a tumor effusion extraction device. Background Art

[0002] During the treatment of tumors, a large amount of fluid may remain in the patient's body. The presence of fluid will cause discomfort to the patient and worsen the condition, so it needs to be cleaned in time. At present, the extraction of tumor fluid is done manually by medical staff. When extracting, the medical staff needs to hold the syringe, then aim it at the location of the tumor fluid, and then insert the syringe into the tumor fluid to extract it. This suction method requires multiple punctures when multiple suctions are required, and each suction requires repositioning. The operation is complicated and will increase the patient's pain. In addition, it is not easy for medical staff to control the depth of syringe insertion when manually extracting, which affects the effect of extracting the fluid. Utility Model Content

[0003] In order to solve the above problems, the purpose of the present invention is to provide a tumor fluid extraction device that can continuously extract the fluid with one puncture and can check the puncture depth of the puncture needle.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present utility model is:

[0005] The air outlet tube of described outer combustion gas pump is connected with the air outlet tube of described outer combustion gas pump, and the air outlet tube has a check valve in its outlet, and the pump is closed by valve in the outlet tube. The top end of the fixing rod is fixedly mounted on the fixing ring, and the fixing rod is fixedly mounted on the fixing ring so as to be in a state of contact with the fixing ring and the fixing hole, and the end portion of the fixing stud is screwed onto the fixing ring and abuts against the sliding rod in the sliding hole. One end of the sliding rod is vertically fixed to the fixing ring, and the axis of the fixing ring coincides with the axis of the liquid pumping cylinder. The sliding rod is provided with a depth scale line along the length direction, and when the connecting ring is at the zero scale of the depth scale line, the bottom surface of the fixing ring is flush with the bottom surface of the puncture needle; the liquid discharge tube is located between the connecting ring and the fixing ring.

[0006] Furthermore, a liquid absorbing layer is installed on the bottom surface of the fixing ring, and the bottom surface refers to the side facing away from the liquid pumping cylinder, and a fixing sticker is installed on the bottom of the liquid absorbing layer.

[0007] Furthermore, a sealing gasket is provided at the one-way valve.

[0008] Furthermore, the liquid extraction cylinder and the liquid collecting bottle are made of transparent materials.

[0009] Furthermore, the liquid collecting bottle is provided with capacity scale lines.

[0010] Furthermore, the air nozzle of the liquid pump is threadedly connected to the air pipe of the inflation and suction dual-purpose pump, and the air pipe is a hose.

[0011] Furthermore, the liquid outlet pipe is threadedly connected to the liquid outlet nozzle, and the liquid outlet pipe is a hose.

[0012] Furthermore, the air pipe and the liquid outlet pipe are retractable bellows.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The utility model inserts a puncture needle into the human body, moves the fixed ring, and causes the slide rod to slide within the slide hole of the connecting ring. When the fixed ring is attached to the patient's skin, the depth of the puncture needle insertion can be seen from the depth scale line on the slide rod. The medical staff can then adjust the depth of the puncture needle insertion. After the adjustment is completed, the slide rod is fixed to the connecting ring using a fixing screw. Because after the fixed ring is fixed to the patient, the fixed ring, slide rod, and connecting ring are connected together with the liquid extraction cylinder, which plays a certain role in fixing the liquid extraction cylinder. When the accumulated fluid leaks from the puncture point, it can be absorbed by the liquid absorption layer on the fixed ring, reducing the impact of the accumulated fluid on the external environment. The inflation and suction dual-purpose pump extracts the gas in the left tube of the liquid extraction cylinder, and the piston moves toward the left tube, so that negative pressure is formed in the right tube of the liquid extraction cylinder. The one-way valve is opened, and the puncture needle inserted into the human body extracts the accumulated fluid in the patient's body into the right tube. When the accumulated fluid in the liquid extraction cylinder reaches a certain volume, the switch of the liquid outlet pipe is opened, and the inflation and suction dual-purpose pump is used to inflate the left tube at the same time. The piston moves toward the right tube, compressing the space in the right tube, and the one-way valve is closed. The accumulated fluid in the right tube flows out of the liquid outlet pipe into the liquid collection bottle. By repeatedly operating the inflation and suction dual-purpose pump in this way, the accumulated fluid in the patient's body can be sucked out with one puncture. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] A specific embodiment, as shown in the figure, is a preferred embodiment of the present invention. A tumor effusion extraction device mainly includes a puncture needle 9, a liquid extraction cylinder 4, an air-inflating and air-inhaling dual-purpose pump 1, and a liquid collection bottle 12. The liquid extraction cylinder 4 is a closed tubular structure. One end of the liquid extraction cylinder 4 is equipped with a puncture needle 9, and the puncture needle 9 is connected to the liquid extraction cylinder 4. A one-way valve is installed on the tube mouth where the puncture needle 9 and the liquid extraction cylinder 4 are connected. The opening direction of the one-way valve is from the puncture needle 9 toward the liquid extraction cylinder 4. The other end of the liquid extraction cylinder 4 is provided with an air nozzle 3, and the air nozzle 3 is connected to the trachea 2. The inflation tube 16 and the suction tube 15 of the inflation and suction dual-purpose pump are connected, and the inflation and suction dual-purpose pump 1 is connected to the liquid pumping cylinder. A piston is installed in the liquid pumping cylinder 4, and the piston slides along the length direction of the liquid pumping cylinder 4. The piston separates the liquid pumping cylinder 4 into two parts, the left cylinder and the right cylinder. The liquid pumping cylinder 4 near one end of the puncture needle 9 is the right cylinder. A liquid outlet nozzle is provided on the right cylinder, and the liquid outlet nozzle is connected to the liquid collection bottle 12 through the liquid outlet pipe 11. A switch 10 is installed on the liquid outlet pipe 11; the piston When sliding to the right end of the cylinder, the piston blocks the liquid outlet nozzle; a measuring fixed structure is detachably mounted on the liquid pumping cylinder 4, and the measuring fixed structure mainly comprises a fixing ring 8, a sliding rod 5, and a connecting ring 6. The connecting ring 6 is arranged on the side wall of the liquid pumping cylinder 4, and a sliding hole is provided on the connecting ring 6. The axis of the sliding hole is parallel to the axis of the liquid pumping cylinder 4, and the sliding rod 5 is slidably connected in the sliding hole. A fixing hole is provided on the side wall of the connecting ring 6, and the fixing hole is communicated with the sliding hole. A fixing stud 7 is threadedly connected to the fixing hole, and the end of the fixing stud 7 abuts against the sliding rod 5 in the sliding hole. One end of the sliding rod 5 is vertically fixed on the fixing ring 8. The axis of the fixing ring 8 coincides with the axis of the liquid extraction cylinder 4. The sliding rod 5 is provided with a depth scale line 14 along the length direction. When the connecting ring 6 is at the zero scale of the depth scale line 14, the bottom surface of the fixing ring 8 is flush with the bottom of the puncture needle 9; the liquid outlet tube 11 is located between the connecting ring 6 and the fixing ring 8.

[0021] During the specific use of the present invention, the part of the patient that needs to be punctured is first disinfected. After the medical staff finds the best puncture point, the puncture needle 9 of the device is used for puncture. The fixing ring 8 in the measurement fixing structure of the device is at the zero scale position of the slide bar 5 before puncture, that is, the fixing ring 8 is away from the needle head of the puncture needle 9, so that the fixing ring 8 will not hinder the puncture of the puncture needle 9. When the puncture needle 9 is inserted into the patient's body, the slide bar 5 is slid so that the fixing ring 8 is attached to the patient's skin. The fixing ring 8 is arranged around the puncture needle 9. The depth scale line 14 on the slide bar 5 can be used to know the length of the puncture needle 9 exposed to the outside. Because the length of the puncture needle 9 is fixed, the depth of the puncture needle 9 inserted into the patient's body can be calculated, which is convenient for medical staff to choose to insert or pull out the puncture needle 9 to adjust the insertion depth of the puncture needle 9 and to facilitate the extraction of tumor fluid. After the medical staff adjusted the degree of depth of puncture needle 9, use fixing screw 7 that slide bar 5 and the connecting ring 6 on the fluid-drawing cylinder 4 are fixed. Further, the bottom surface of described fixing screw 8 is equipped with imbibition layer, and described bottom surface refers to the one side away from fluid-drawing cylinder 4, and the bottom of described imbibition layer is equipped with fixing patch.By fixing patch on the fixing screw 8, fixing patch is fixed on the skin surface of patient, the distance of fixing screw 8 and the connecting ring 6 on the fluid-drawing cylinder 4 is fixed by sliding bar 5 and fixing screw 7, thereby makes measuring fixed structure and fluid-drawing cylinder 4 plays certain limiting effect, makes the puncture needle 9 on the fluid-drawing cylinder 4 in the process of extracting effusion, be difficult for being pulled out or deepen the piercing depth, improves safety.The imbibition layer installed on the fixing screw 8, because fixing screw 8 is located around the puncture needle 9, can absorb the tumor effusion that puncture point leaks in the process of extracting effusion, prevents from polluting external environment. When using this device, the suction pipe 15 and the inflation pipe 16 are not opened at the same time. Further, the suction pipe 15 and the inflation pipe 16 are both provided with an air valve. The switch 10 on the liquid outlet pipe 11 of this device is closed in the initial state. After the puncture needle 9 is inserted into the patient's body, the inflation and suction dual-purpose pump 1 is started and the suction function is used. At this time, the suction pipe 15 is opened and the inflation pipe 16 is closed. The gas in the left tube of the liquid pumping cylinder 4 is extracted through the suction pipe 15, so that the piston slides to one side of the left tube. The air pressure in the right tube is reduced to form a negative pressure. The one-way valve at the connection point between the right tube of the liquid pumping cylinder 4 and the puncture needle 9 is opened, and the tumor effusion in the patient's body is extracted. Further, the liquid pumping cylinder 4 and the liquid collecting bottle 12 are made of transparent material.After observing that the tumor effusion in the liquid pumping cylinder 4 has reached a certain capacity, the suction function of the inflation and suction dual-purpose pump 1 is turned off, the suction pipe 15 is closed, the inflation pipe 16 is opened, and the inflation function is started to inflate the left cylinder, so that the piston in the liquid pumping cylinder 4 slides toward the right cylinder side, compressing the space in the right cylinder. The one-way valve is closed so that the tumor effusion does not flow back into the patient's body, and does not affect the patient. Then the switch 10 on the liquid outlet pipe 11 is opened, so that the tumor effusion in the right cylinder flows out from the liquid outlet pipe 11 into the liquid collecting bottle 12. When the piston slides to the end of the right cylinder, the piston is blocked by the liquid outlet nozzle, and the liquid outlet nozzle is not exposed to the left side of the piston. When the inflation and suction dual-purpose pump 1 is started again, the tumor effusion in the liquid collecting bottle 12 will not be sucked into the left cylinder through the liquid outlet nozzle, and will not contaminate the left cylinder and will not contaminate the inflation and suction dual-purpose pump 1, making the inflation and suction dual-purpose pump 1 reusable and usable by each patient without cross infection. After the effusion in the right tube is squeezed into the fluid collecting bottle 12, the switch 10 on the liquid outlet pipe 11 is turned off, and the suction function of the inflation and suction dual-purpose pump 1 is restarted to continue to draw the tumor effusion in the patient's body. By repeatedly using the inflation and suction functions of the inflation and suction dual-purpose pump 1, it is possible to continuously extract tumor effusion until the extraction is completed, thereby achieving the purpose of completing the extraction of effusion with only one puncture. Furthermore, the liquid outlet pipe 11 is located between the connecting ring 6 and the fixing ring 8, which will not affect the attachment of the fixing ring 8 to the patient's skin, and allows the liquid outlet pipe 11 to be as close to the end of the right tube as possible. When the piston slides to the end of the right tube, the liquid outlet nozzle will not be exposed to the left side of the piston, nor will the liquid outlet nozzle be blocked prematurely, so that the effusion in the right tube is discharged as much as possible.

[0022] Furthermore, a sealing gasket is provided at the one-way valve to improve the sealing performance of the one-way valve. When the piston slides to the right to squeeze the space of the right cylinder, the risk of tumor fluid in the right cylinder flowing back into the patient's body can be further reduced.

[0023] Furthermore, the fluid collection bottle 12 is provided with a capacity scale line 13 to facilitate understanding of the amount of tumor fluid extracted.

[0024] Furthermore, the air nozzle 3 of the liquid suction cylinder 4 is threadedly connected to the air pipe 2 of the inflation and suction dual-purpose pump 1. The air pipe 2 is a hose, which is convenient for disassembly and assembly. The air pipe 2 is a hose, which is convenient for adjusting the position of the inflation and suction dual-purpose pump 1 without affecting the puncture of the puncture needle 9.

[0025] Furthermore, the liquid outlet pipe 11 is threadedly connected to the liquid outlet nozzle. The liquid outlet pipe 11 is a hose, which makes it convenient to remove and replace the liquid outlet pipe 11. The liquid collecting bottle 12 connected to the liquid outlet pipe 11 is convenient to adjust its placement position and will not affect the puncture of the puncture needle 9.

[0026] Furthermore, the trachea 2 and the liquid outlet pipe 11 adopt a retractable bellows, which is convenient for adjusting the length, so that the distance between the inflation and suction dual-purpose pump 1 connected to the trachea 2 and the liquid collecting bottle 12 connected to the liquid outlet pipe 11 and the patient can be adjusted. The length will not be too short and close to the patient or the puncture point, affecting the puncture or liquid extraction, nor will the trachea 2 and the liquid outlet pipe 11 be entangled or easily pulled due to being too long.

[0027] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
