Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary accessories, and in particular to a drainage tube suction device. Background Art

[0002] Ventricular drainage in neurosurgery is an important treatment method, mainly used to treat some hemorrhagic diseases, severe craniocerebral trauma or central nervous system diseases. It has a significant effect on reducing intracranial pressure and improving the obstruction of cerebrospinal fluid circulation pathways.

[0003] However, in the existing drainage tubes, empty tubes are usually used for drainage, which will result in cavity air pressure between the empty tube and the ventricle, requiring medical personnel to exert force continuously to operate the drainage; this places high demands on the working ability of medical personnel.

[0004] In order to reduce the work requirements, we proposed a drainage method using liquid, which causes the liquid to be gradually discharged through pressure to achieve ventricular drainage of the patient. Summary of the invention

[0005] In view of the defects in the prior art, the present invention provides a drainage tube suction device to reduce the operational capability requirements for medical staff and achieve ventricular drainage of patients.

[0006] In a first aspect, the present invention provides a drainage tube suction device, comprising: a main pipe; a piston body, which is slidably installed in the main pipe and can slide outward; and a connecting needle, one end of which is connected to the main pipe, and liquid is injected between the piston body and the connecting needle.

[0007] Furthermore, the main pipe is made of a flexible material. In actual use, the material is made of medical-grade rubber material.

[0008] Furthermore, it also includes a pressing capsule, the piston body is provided with a central connection mounting hole, the pressing capsule is provided with a connecting section, the connecting section is installed on the central connection mounting hole, and is sealed and connected to the central connection mounting hole. In actual use, the pressing capsule is installed in the piston body, mainly to realize the movement of the piston body, which is achieved by subsequently changing the pressure of the liquid injected between the piston body and the connecting needle. In this way, the movement of the piston body in the main pipe can be realized under the action of pressure, thereby realizing the ventricular drainage of the patient connected to the connecting needle.

[0009] Furthermore, the pressing bag is also provided with a pressing section, a sealing section and a sealing valve body; one end of the pressing section is communicated with the connecting section, and the other end of the pressing section is communicated with the sealing section; the valve body is installed in the sealing section and is sealed and connected with the sealing section. In actual use, the medical staff first presses the pressing section, and the pressing section will separate the sealing valve body on the sealing section from the sealing section under the action of pressure. In this way, when the pressing section rebounds, pressure will be sucked from the main pipe, so that the air pressure will enter the connecting section from the sealing section, thereby breaking the pressure balance between the piston body and the connecting needle. In this way, the pressurized pressure will push the above-mentioned piston body to slide in the main pipe, so that the dynamic balance of the piston body and the main pipe is broken again. In this way, under the push of the piston body, the liquid injected between the piston body and the connecting needle is pulled out, so that the patient's ventricle connected to the connecting needle is drained, and the relevant liquid flowing out of the ventricle during the drainage will also be continuously replenished between the piston body and the connecting needle. In this way, continuous drainage of the patient's ventricle can be achieved, and the whole process only needs to be pressed once, and the volume capacity of the main pipe can be changed to achieve the drainage of the liquid capacity. In this way, one-time operation is achieved, which is simple and fast, and greatly reduces the operating ability requirements for medical staff.

[0010] Furthermore, the pressing capsule also includes an abutting valve body, the connecting section is provided with an abutting notch, and the abutting notch is close to the pressing section; the abutting valve body is abutted and installed on the abutting notch. In actual use, in order to ensure that the pressure generated by pressing the pressing capsule will only impact in a unidirectional direction toward the sealing section to achieve the opening of the sealing valve body and the sealing section, the connecting section achieves a sealing effect when the abutting notch abuts against the abutting valve body, and the pressure generated by pressing the pressing capsule will only rush out from the sealing section.

[0011] Furthermore, the pressing capsule is also provided with a connecting line, one end of which is connected to the abutting valve body, and the other end of which is connected to the sealing valve body. In actual use, the purpose of this design is to drive the abutting valve body and the sealing valve body to fall off together, wherein when the sealing valve body is impacted and falls off, the abutting valve body will also fall off together under the drive of the connecting line, so that the connecting section is opened, and the liquid injected between the piston body and the connecting needle can flow.

[0012] Furthermore, it also includes a protective sleeve, which is slidably mounted on the main pipe and close to the direction of the piston body. In actual use, the protective sleeve plays a protective role, so that the phenomenon of accidental touch can be reduced.

[0013] Furthermore, it also includes a peristaltic pump, which is used to press the main pipe. In actual use, this component starts the secondary start-up function and realizes adjustment through external pressure.

[0014] It can be seen from the above technical solution that the beneficial effects of the drainage tube suction device provided by the present invention are:

[0015] (1) In actual use, the working principle adopted in this design is to achieve drainage through the change of liquid flow pressure, and to maintain the above-mentioned liquid flow pressure change through the sliding of the piston body. In this way, a continuous drainage effect can be achieved, which greatly reduces the difficulty of operation. Medical workers do not need to operate for a long time. Only one operation is needed to make the piston body slide;

[0016] (2) The sliding of the piston body is slow, so that the movement of the piston body can be kept orderly, which reduces the proficiency requirements of medical personnel and greatly facilitates application;

[0017] (3) The liquid used is medical saline, which is not only easy to obtain but also sterile, reducing the risk of infection during the drainage operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In the first aspect, the present invention provides a drainage tube suction device, comprising: a main tube 1; a piston body 2, the piston body 2 is slidably installed in the main tube 1 and can slide outward; and a connecting needle 3, one end of the connecting needle 3 is connected to the main tube 1, and liquid is injected between the piston body 2 and the connecting needle 3. In actual use, in this design, the working principle adopted is to achieve drainage through the change of liquid flow pressure, and to maintain the above-mentioned liquid flow pressure change through the sliding of the piston body 2, so that a continuous drainage effect can be achieved, which greatly reduces the difficulty of operation, and does not require medical workers to operate for a long time, and only needs one operation to make the piston body 2 slide; wherein the sliding of the piston body 2 is a slow sliding, so that the movement of the piston body 2 can be maintained in an orderly manner, so as to reduce the proficiency requirements of medical personnel; it is greatly convenient to use; at the same time, the liquid used is medical physiological saline, so that it is not only easy to obtain, but also sterile, reducing the risk of infection during drainage surgery.

[0029] In this embodiment, for the convenience of operation, the main tube 1 is made of a flexible material. In actual use, the material is made of medical grade rubber material.

[0030] In this embodiment, a pressing capsule 4 is also included, the piston body 2 is provided with a central connection mounting hole 21, the pressing capsule 4 is provided with a connecting section 41, the connecting section 41 is installed on the central connection mounting hole 21, and is sealed and connected to the central connection mounting hole 21.

In this way, the movement of the piston body 2 in the main pipe 1 can be achieved under the action of pressure, thereby realizing the ventricular drainage of the patient connected to the connecting needle 3.

In actual use, the pressing section 42 is first pressed by medical personnel, and the pressing section 42 will separate the sealing valve body 44 on the sealing section 43 from the sealing section 43 under the action of pressure. In this way, when the pressing section 42 rebounds, it will inhale pressure from the main pipe 1. In this way, the air pressure will enter the connecting section 41 from the sealing section 43, thereby breaking the pressure balance between the piston body 2 and the connecting needle 3.

In actual use, the purpose of this design is to drive the abutting valve body 45 and the sealing valve body 44 to fall off together, wherein when the sealing valve body is impacted and falls off, the abutting valve body 45 will also fall off together under the drive of the connecting line 46, so that the connecting section 41 is opened, and the liquid injected between the piston body 2 and the connecting needle 3 can flow.

[0034] In this embodiment, in order to avoid accidental activation, a protective sleeve 5 is further included, which is slidably mounted on the main pipe 1 and close to the direction of the piston body 2. In actual use, the protective sleeve 5 plays a protective role, which can reduce the occurrence of accidental activation.

[0035] In order to prevent an emergency, in this embodiment, a peristaltic pump 6 is further included, and the peristaltic pump 6 is used to press the main pipe 1. In actual use, this component starts the secondary start-up function and realizes adjustment through external pressure.
