TECHNICAL FIELD
[0001] The utility model belongs to the drainage tube field, concretely is a kind of abdominal cavity drainage tube that can directly measure intra-abdominal pressure change. BACKGROUND
[0002] Abdominal surgery is an important means of treating various abdominal diseases. In order to ensure the patency of the surgical area and the smooth recovery of the disease, different numbers of abdominal drainage tubes need to be placed in the surgical area and its vicinity after surgery. Conventional abdominal drainage tubes play a role in drainage and / or increasing flushing function to some extent, and have a positive auxiliary effect on the recovery of patients. However, in actual clinical practice, some patients may experience a sharp increase in intra-abdominal pressure due to changes in their condition, such as intra-abdominal bleeding, severe infection, extensive intestinal distension, or a large amount of ascites, which can pose a significant risk of critical illness or even death to the patient. Therefore, in order to more comprehensively evaluate the therapeutic effect and monitor the patient's condition in real time, medical personnel need to closely monitor the changes in intra-abdominal pressure of postoperative patients.
[0003] Currently, the commonly used pressure measurement method is to insert a three-lumen urinary catheter with pressure measurement function into the bladder to indirectly obtain the change in abdominal pressure. Although this method can obtain indirect pressure measurement data, it has some limitations. The method is relatively complex to operate, requires additional replacement of the original conventional urinary catheter, and increases the risk and discomfort of the patient. Moreover, the indirect measurement method may have some errors due to the influence of various factors, and cannot accurately and timely reflect the real changes in intra-abdominal pressure.
[0004] In contrast, directly measuring abdominal pressure should be more effective. However, the existing conventional drainage tube does not have the function of directly measuring intra-abdominal pressure, which makes it difficult for medical personnel to accurately judge and timely treat the patient's condition. Therefore, it is of great clinical significance and practical value to develop an abdominal drainage tube that can directly measure intra-abdominal pressure. SUMMARY
[0005] To solve the above problems, the utility model provides a kind of abdominal cavity drainage tube that can measure pressure, can directly monitor the change of pressure value in abdominal cavity drainage tube, so that medical staff can make corresponding response plan in time according to pressure change.
[0006] To achieve the above purpose, the following technical means are specifically adopted in the present application:
[0007] The utility model provides a kind of measurable abdominal cavity drainage tube, including drainage tube, a pressure measuring tube is arranged in the side wall of the drainage tube, a sealing member is provided in the pressure measuring tube, the sealing member is adapted to the cavity of pressure measuring tube, the sealing member can be moved down along the inner wall of pressure measuring tube, and the elastic member of compressible is connected below the sealing member;The upper end of the pressure measuring tube is placed into abdominal cavity with the drainage tube and is in open state, the lower end is closed and is equipped with pressure sensor, and the elastic member is connected to the pressure sensor, and the pressure sensor transmits pressure value change to pressure value display screen by wire.
[0008] Further, the diameter of the pressure measuring tube is 1 / 3 of the drainage tube and is equal in length with the drainage tube, and the sealing member is located at 1 / 6 of the pressure measuring tube.
[0009] Further, pressure value scale is set inside the pressure measuring tube at a distance, for reflecting the pressure change value suffered by the sealing member.
[0010] Further, a small hole is provided at the lower end of the pressure measuring tube, and a branch is provided in the drainage tube.
[0011] The utility model has the following beneficial technical effects:
[0012] By arranging the pressure measuring tube in the side wall of the drainage tube, the cooperation of the sealing member, the elastic member and the pressure sensor in the pressure measuring tube can measure the pressure change in the abdominal cavity in real time and accurately. Compared with the traditional indirect measurement method, such as putting the three-cavity catheter with pressure measuring function into the bladder through the urethra, the present application directly realizes the pressure measuring function on the abdominal cavity drainage tube, reduces the error caused by indirect measurement, and provides more reliable basis for the judgment of the medical staff.
[0013] The pressure value scale is set inside the pressure measuring tube, so that the medical staff can directly observe the pressure change value suffered by the sealing member, and more comprehensively understand the pressure condition in the abdominal cavity by combining the data of the pressure value display screen, which helps to discover the abnormality in time and take corresponding treatment measures.
[0014] The abdominal cavity drainage tube has relatively simple structure, and no complex operation and additional equipment preparation are needed during use. The medical staff only needs to place the drainage tube with the pressure measuring tube into the abdominal cavity, and then the pressure value in the abdominal cavity can be directly obtained through the pressure value display screen, so that the operation difficulty and work burden are reduced, and the work efficiency is improved.

[0017] The other advantages and functions of the present application can be easily understood by those skilled in the art from the disclosure of this specification. The present application can also be implemented or applied in other different specific embodiments, and various modifications or changes can be made to the details in this specification based on different views and applications without departing from the spirit of the present application. It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present application in a schematic manner, and the following embodiments and features in the embodiments can be combined with each other without conflict.
[0018] The drawings are only used for exemplary illustration, and the representation is only a schematic diagram, not a physical diagram, and cannot be understood as a limitation on the present application; in order to better illustrate the embodiments of the present application, some components in the drawings are omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, the omission of some well-known structures and their descriptions in the drawings is understandable.
[0019] The present application provides a pressure-measurable abdominal cavity drainage tube. A pressure measuring tube for measuring pressure and a display screen for directly displaying pressure changes are added to the conventional abdominal cavity drainage tube, and the degree of extrusion of the pressure sensor directly reflects the changes of the pressure in the abdominal cavity of the patient.
[0020] Please refer to Figure 1 The pressure-measurable abdominal cavity drainage tube mainly comprises a drainage tube 1 and a pressure measuring tube 2. The pressure measuring tube 2 is arranged on the side wall of the drainage tube 1, and the diameter of the pressure measuring tube 2 is 1 / 3 of the diameter of the drainage tube 1 and is equal in length to the drainage tube 1. The above-mentioned size design not only ensures that the pressure measuring tube 2 can accurately measure the pressure, but also does not significantly affect the drainage function of the drainage tube 1. The upper end of the pressure measuring tube 2 is placed into the abdominal cavity together with the drainage tube 1, and is in an open state, so that the pressure in the abdominal cavity can be smoothly transmitted into the pressure measuring tube 2; the lower end is closed to ensure the accuracy of the measurement.
[0021] In the pressure measuring tube 2, a waterproof plugging member 3 is arranged which is tightly matched with the pressure measuring tube cavity. The plugging member 3 is located at 1 / 6 of the pressure measuring tube 2, and the material thereof is selected from medical silica gel. This material has good biocompatibility and softness, which can effectively plug the pressure measuring tube 2 and will not harm the patient. The shape of the plugging member 3 is designed as a cylinder, and the surface thereof is treated in a special way, so that the friction coefficient is low, and the plugging member 3 can smoothly move down along the inner wall of the pressure measuring tube 2. The plugging member 3 is connected with a compressible elastic member 4 below, and the elastic member 4 in this embodiment is selected from a high-strength medical spring. This spring has excellent elastic recovery ability and fatigue resistance, and can still maintain stable performance even during long-term use, thereby ensuring the reliability of the measurement results.
[0022] In addition, the pressure measuring tube 2 is provided with pressure value scales 8 at intervals. When the blocking piece 3 passes through the corresponding scale each time, it means that the abdominal cavity pressure increases by about 5mmHg each time. This provides a direct judgment method for medical staff, so that they can know the approximate change of the abdominal cavity pressure more quickly. The lower end of the pressure measuring tube 2 is provided with a small hole, and the drainage tube 1 is provided with a branch. The pressure sensor 5 passes out of the small hole of the pressure measuring tube through the wire 6 and is connected with the pressure value display screen 7 through the drainage tube branch 9. The pressure sensor 5 can sensitively perceive the change of the compression degree of the elastic piece 4 and convert it into an electric signal, which is accurately transmitted to the pressure value display screen 7 through the wire 6 for real-time display.
[0023] In actual use, medical staff places the abdominal cavity drainage tube of the utility model into the abdominal cavity of a patient according to the conventional operation, at this time, the pressure measuring tube 2 also enters the abdominal cavity. When the abdominal cavity pressure changes, the pressure acts on the blocking piece 3 through the open end of the pressure measuring tube 2, so that the blocking piece 3 moves downward along the inner wall of the pressure measuring tube 2 and compresses the elastic piece 4. After the compression degree of the elastic piece 4 is accurately perceived by the pressure sensor 5, it is converted into an electric signal and transmitted to the pressure value display screen 7, so that the pressure value is directly displayed. At the same time, medical staff can also observe the pressure value scales 8 in the pressure measuring tube 2, more comprehensively master the change trend of the pressure borne by the blocking piece 3, and more accurately judge the change of the abdominal cavity pressure of the patient.
[0024] In summary, the abdominal cavity drainage tube with pressure measurement function has simple structure and convenient operation, can directly and accurately measure the abdominal cavity pressure, provides a convenient and reliable disease monitoring method for medical staff, and is helpful to improve the medical quality and the rehabilitation effect of the patient.
