Description

Technical Field

[0001] The present application belongs to the technical field of medical negative pressure devices, and specifically relates to a negative pressure aspirator for a medical pendant. Background Art

[0002] A medical negative pressure aspirator is a commonly used medical device. Its main purpose is to provide the function of suctioning sputum, blood, pus and other secretions by connecting the medical machine to the medical center negative pressure suction system. Existing negative pressure aspirators are generally connected to the central negative pressure suction station in the hospital by inserting their own connecting connectors into the negative pressure suction interface of the ward. With the continuous upgrading of medical equipment, the functions of medical pendants are becoming more and more perfect. Existing medical pendants have realized the integration of negative pressure suction interfaces. However, due to the limitation of the installation position, it is inconvenient to observe the working status of the negative pressure aspirator when the traditional negative pressure aspirator is directly connected to the negative pressure suction interface of the medical pendant. In addition, the suction hose connected to the patient is relatively long, which not only brings the risk of infection to the patient, but also the long suction hose is easy to entangle and affect the effect of negative pressure suction. At the same time, it will also affect the medical staff's rescue work near the medical pendant. Summary of the invention

[0003] The present application proposes a negative pressure aspirator for a medical pendant. Through the installation components on the negative pressure aspirator, the negative pressure aspirator can be installed at a suitable position on the medical pendant as needed, so that medical staff and patients can check the working status of the negative pressure aspirator at any time, and are no longer restricted by the position of the negative pressure aspiration interface of the medical pendant. It is convenient and flexible, and the installation or disassembly operation is simple.

[0004] The specific technical solution adopted in this application is: a negative pressure aspirator for a medical pendant, comprising a pressure regulating valve, a storage bottle, a connecting pipe, a mounting assembly and an air guide hose;

[0005] The storage bottle is provided with a liquid inlet for connecting an external drainage tube, and the storage bottle, the pressure regulating valve and the connecting tube are connected in sequence;

[0006] The mounting assembly can be fixed to a medical pendant, and a channel is provided in the mounting assembly, and an end of the connecting pipe away from the pressure regulating valve is connected to one end of the air guide hose through the channel;

[0007] The other end of the air guide hose is provided with a negative pressure suction connector, and the negative pressure suction connector is used for plugging and cooperating with an external negative pressure terminal interface.

[0008] Furthermore, the mounting assembly includes a mounting seat and two L-shaped blocks relatively arranged on the mounting seat, and at least one of the L-shaped blocks is slidably arranged on the mounting seat so that the two L-shaped blocks are moved closer to or farther away from each other.

[0009] Further, a limiting groove is formed in the mounting base. The two L-shaped blocks are a first L-shaped block and a second L-shaped block. The first L-shaped block is fixed on the mounting base, and the second L-shaped block is slidably arranged in the limiting groove.

[0010] Further, the mounting assembly further includes a compression spring, and two ends of the compression spring are respectively connected to the first L-shaped block and the second L-shaped block.

[0011] Further, the mounting assembly further includes a press pin. The press pin is slidably arranged in the limiting groove and abuts against the second L-shaped block so as to be able to push the second L-shaped block to move away from the first L-shaped block.

[0012] Further, the air guide hose is a telescopic hose.

[0013] Further, a pressure gauge is further included, and the pressure gauge is arranged on the pressure regulating valve.

[0014] Further, the pressure regulating valve has a pressure regulating knob capable of rotating to adjust the magnitude of the negative pressure.

[0015] Further, anti-slip strips are uniformly arranged on the circumferential direction of the pressure regulating knob.

[0016] Generally speaking, the above technical solutions conceived by the present application can achieve the following beneficial effects: By adding a mounting assembly to the negative pressure aspirator, the negative pressure aspirator can be mounted on a medical suspension tower through the mounting assembly. Instead of directly inserting the traditional negative pressure aspirator into the negative pressure suction interface, the air guide hose of the negative pressure aspirator is inserted into the negative pressure suction interface, which increases the flexibility of the installation of the negative pressure aspirator. The installation position can be changed at any time according to needs. When the installation position is far from the negative pressure suction interface, only a suitable length of air guide hose needs to be replaced, and there is no need to increase the length of the drainage tube connected to the patient, so that the length of the drainage tube exposed to the environment is as short as possible, thereby reducing the risk of wound infection of the patient; The pressure regulating valve on the negative pressure aspirator is provided with a pressure regulating knob capable of rotating to adjust the magnitude of the negative pressure, and the magnitude of the negative pressure can be adjusted according to different usage scenarios to better meet the needs of various different treatment situations.

[0025] Such as Figure 1-2As shown, a negative pressure aspirator for a medical pendant of the present application includes a pressure regulating valve, a storage bottle, a connecting pipe, a mounting assembly and an air guide hose. The storage bottle is detachably connected to the pressure regulating valve, and a liquid inlet is provided on the upper part of the storage bottle for connecting an external drainage tube, and the storage bottle, the pressure regulating valve and the connecting pipe are connected in sequence. In order to avoid entanglement due to the excessive length of the air guide hose, the air guide hose is configured as a retractable hose; the mounting assembly is used to fix the negative pressure aspirator of the present application to the medical pendant, and a channel is provided in the mounting assembly, and the end of the connecting pipe away from the pressure regulating valve is connected to one end of the air guide hose through the channel, and the other end of the air guide hose is provided with a negative pressure suction connector, which is used to be plugged in and used in conjunction with an external negative pressure terminal interface.

[0026] like Figures 3-4 As shown, the mounting assembly includes a mounting seat and a first L-shaped block and a second L-shaped block that are arranged opposite to each other. At least one L-shaped block is slidably arranged on the mounting seat so that the two L-shaped blocks are close to or away from each other, which is convenient for installation on the medical pendant or disassembly. The mounting seat is provided with a vertical limit groove, and the first L-shaped block and the second L-shaped block are arranged in the limit groove. In this embodiment, the first L-shaped block is fixedly installed on one side of the mounting seat where the limit groove is provided by screws, and the second L-shaped block can slide up and down along the limit groove, and the lower end of the limit groove does not penetrate the mounting seat, which can prevent the second L-shaped block from sliding off from the lower end of the limit groove. In order to facilitate the first L-shaped block and the second L-shaped block to approach or move away from each other, a pressing pin and a compression spring are further provided, the pressing pin is slidably arranged in the limiting groove, and both ends of the compression spring are respectively fixedly connected to the lower end surface of the first L-shaped block located in the limiting groove and the upper end surface of the second L-shaped block located in the limiting groove, and a through hole for the pressing pin to pass through is provided in the first L-shaped block, and the pressing pin passes through the first L-shaped block from top to bottom and abuts against the upper end surface of the second L-shaped block. When the pressing pin is pressed, the second L-shaped block moves in a direction away from the first L-shaped block, and the compression spring is stretched, so that the negative pressure suction device of the present application is moved to the position to be installed, and the installation position is placed between the first L-shaped block and the second L-shaped block. When the pressing pin is released, the second L-shaped block moves in a direction close to the first L-shaped block under the action of the rebound tension of the compression spring until it abuts against the installation position, thereby completing the clamping installation of the negative pressure suction device of the present application.

[0027] In order to facilitate observation of the magnitude of the negative pressure, the present embodiment is further provided with a pressure gauge, which is arranged on the pressure regulating valve. When the negative pressure is turned on, the real-time magnitude of the negative pressure can be read on the pressure gauge. At the same time, in order to facilitate the adjustment of the magnitude of the negative pressure, the pressure regulating valve has a pressure regulating knob that can be rotated to adjust the magnitude of the negative pressure. Preferably, the circumference of the pressure regulating knob of the pressure regulating valve is evenly arranged with raised anti-slip strips to facilitate the rotation of the pressure regulating knob.

[0028] The working principle of a negative pressure aspirator for a medical suspension tower in this application is as follows: The negative pressure aspirator is clamped to one side of the tray of the medical suspension tower through a mounting component. By inserting the negative pressure suction connector at one end of the air guiding hose into the negative pressure interface on the medical suspension tower, the negative pressure aspirator can be connected to the in-hospital central negative pressure suction station. Since the air guiding hose can be bent arbitrarily and can be replaced with a suitable length as needed, the negative pressure aspirator can be installed at any place on the medical suspension tower that is convenient for medical staff to operate according to the treatment needs. This is not only convenient for doctors and patients to use but also does not interfere with the normal rescue work of medical staff. One end of the external drainage tube is inserted into the part of the patient where the secretions need to be aspirated, and the other end is connected to the liquid inlet of the storage bottle. The negative pressure is output to the pressure regulating valve through the connecting tube. By rotating the pressure regulating knob on the pressure regulating valve, the magnitude of the negative pressure can be adjusted as needed. The negative pressure enters the storage bottle through the connecting tube and the pressure regulating valve. At this time, the inside of the storage bottle is in a negative pressure state. Under the action of the negative pressure, secretions such as sputum, blood, and pus in the patient's body can be aspirated through the drainage tube and drained into the storage bottle. Since the negative pressure aspirator can be installed at a suitable position on the medical suspension tower, medical staff, patients, or patient family members can more conveniently observe the working condition of the negative pressure aspirator installed on the medical suspension tower. In case of emergencies such as reflux, blockage, or discomfort of the patient during use, the negative pressure aspirator can be operated in time to stop working, effectively avoiding the occurrence of danger.

[0029] It is easy for those skilled in the art to understand that the above is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of this application shall be included in the protection scope of this application.
