Description

Negative pressure clean bench

Technical Field

The utility model belongs to the technical field of medical safety equipment technique and specifically relates to a negative pressure clean bench.

Background

The glass plates are arranged above the working tables at places such as registration rooms, inspection rooms, pharmacies, ward nurse tables and the like of hospitals, patients and medical staff are separated through the glass plates, the medical staff need to face a large number of patients every day, the density of iatrogenic bacteria and viruses under the environment where the working tables are located is high, and the situation that the medical staff are cross-infected is easily caused. With regard to the workstation, at present, along with the patient examination sample quantity in hospital's continuous increase, some great hospitals of scale one day blood sample quantity have 6000 ~ 10000 approximately, and medical personnel's chance that contacts bacterium, virus improves greatly. For example, chinese patent CN208464543U discloses an isolated medical workstation, which utilizes separation glass arranged on a working table to separate medical staff from a patient, but the shape of the U-shaped notch is large, the table part is still not blocked by glass, and the distance between the medical staff and the patient is less than 50 cm when blood is collected, so that there is a risk of virus propagation during the blood collection process of the medical staff to the patient.

SUMMERY OF THE UTILITY MODEL

The applicant aims at the defect that the workbench in the existing production has virus propagation risks, and provides a negative pressure clean workbench with a reasonable structure, so that virus propagation possibly existing between medical workers and patients is effectively prevented, and the medical workers are better protected.

The utility model discloses technical scheme and beneficial effect who adopts as follows:

a negative pressure clean workbench is provided with a separation plate above the workbench surface, an air suction opening is arranged on the corresponding workbench surface at the lower part of the separation plate, and the air suction opening is driven by an air suction fan to suck air. Form negative pressure wind on the workstation mesa, the inlet scoop inhales the air of little window both sides is whole, makes the outside air that is close to the patient can not get into the inboard at medical personnel place through little window to keep apart the workstation outside and inboard, keep apart medical personnel, prevent that the virus that outside patient carried from getting into medical personnel workspace, guarantee the cleanness of workspace.

As a further improvement of the above technical solution:

the inlet scoop sets up on the mesa of patient one side, guarantees that the air of the position above the mesa of outside patient place is inhaled as far as possible, prevents the virus to internal propagation better, keeps apart the effect stronger.

The lower part of the isolation plate is provided with a small window, and only the table top at the corresponding position of the small window is provided with an air suction opening. And only the small window is provided with the air suction opening, so that the air quantity of the fan can be reduced, the loads of disinfection and filtration are reduced, and the use cost is saved.

The air suction opening is transversely arranged along the width direction of the isolation plate; the air suction openings are circular hole-shaped structures arranged in an array. The circular hole-shaped structure that the preferred array of inlet scoop was arranged can prevent that the mesa object from dropping and getting into return air mechanism, influences the filter effect.

The air suction inlet is connected with the filter, the air suction fan and the air outlet through pipelines, the filter and the air suction fan are arranged in the workbench, and the air outlet is positioned on an outer plate at the bottom of the workbench, facing to one side of a patient; the air outlet exhausts air downwards. Because filter and induced draft fan all set up inside the workstation, therefore every workstation works alone, can the exclusive use, and it is more convenient to carry and change the place of use.

The filter is arranged at a position close to the air outlet; the filter and the suction fan are positioned in the workbench at one side of the patient. The filter can set up in the position that is close to the air outlet, can change the filter screen through the air outlet, need not to unpack apart whole workstation, and it is more convenient to change. The filter and the air suction fan are arranged inside the workbench and positioned on one side of the patient, and the internal space close to one side of the medical staff can be vacated so as to allow the medical staff to store articles.

An air supply device is arranged below or at the bottom of the partition plate, an air supply opening facing the air suction opening is formed in the air supply device, air is sprayed to the air supply opening through an air supply fan, the air supply opening and the air suction opening work simultaneously to form an air curtain, and the air curtain covers a space area between the bottom of the partition plate and the table board. Meanwhile, air supply and air return are started, and an air curtain with stronger air flow is formed between the glass plate of the workbench and the table top, so that the effect of internal and external isolation is better formed. The air supply outlet faces the air suction inlet, and the power of the air suction fan can be reduced.

The air supply quantity of the air supply fan is less than the return air quantity of the lower air suction fan. The air supply fan and the air suction fan are both connected with the air volume controller. The air supply volume is less, and the wind that the blast hole blew to the mesa just can not blow respectively to medical personnel and patient to the desktop both sides in a large number, also can prevent that wind from blowing the virus of the patient arm portion of taking a blood sample to medical personnel. The air supply fan and the air suction fan are both connected with the air volume controller, so that the air volume can be conveniently controlled.

The air supply outlet is of a grid structure, and grid strips are parallel to the length direction of the table top. The air supply outlet is preferably of a grid structure, and grid strips are parallel to the length direction of the table top, so that a complete air curtain can be formed better, and leakage points of the air curtain are avoided.

The air return pipelines of the plurality of working tables are arranged in series and are connected with a filter and an air suction fan outside the working tables; the air feeder is arranged at a certain angle towards the inner side of the workbench, and the air supply outlet is vertically downward; an arm detector is arranged on the air feeder; the automatic disinfection device and the photoelectric detection device are arranged on the inner side or the outer side of the air blower.

A plurality of working tables can be arranged in parallel, a communicated return air pipeline is used for being connected in series, the same filter and the suction fan are centralized for processing, and the centralized control of a large number of working tables is realized. The air supply device can be inclined to the inner side of the workbench by a certain angle, the air supply opening is vertical downward, the part of a hand of a patient extending into the air curtain and exposed to medical staff is less, and the medical staff is prevented from contacting more arm parts. Set up the arm detector on the air feeder, the position of wrist, elbow can automatic monitoring by the arm detector to follow the arm removal air feeder that stretches into, guarantee that the arm that the patient stretched into just exposes the blood sampling point, avoid the patient to expose more arm parts. The automatic disinfection device and the photoelectric detection device are arranged on the inner side or the outer side of the air feeder, the photoelectric detection device can detect the position of the arm, and when the arm is detected to extend, the arm is automatically sprayed with disinfectant to be disinfected.
