Description

Technical Field

[0001] The utility model relates to the technical field of temperature calibration of a sterilizing pot, in particular to a temperature calibration device for a sterilizing pot. Background Art

[0002] Sterilizer, also known as steam sterilizer, is a device that uses saturated pressure steam to quickly and reliably sterilize items. It is suitable for medical care, scientific research, agriculture and other fields. It can sterilize medical equipment, dressings, glassware, solution culture media, etc. Sterilizers can be divided into three types according to their capacity: portable, vertical, and horizontal. According to the temperature control method, they can be divided into non-automatic temperature control sterilizers and automatic temperature control sterilizers.

[0003] For non-automatic temperature control autoclaves, cold air must be exhausted when in use. If the cold air is not exhausted, the cold air will expand thermally and affect the working pressure of the pressure cooker, causing the pressure and temperature to not correspond one to one. The displayed temperature is higher than the actual working temperature in the pot, and the working temperature of the autoclave cannot reach the set sterilization temperature, which will affect the sterilization effect. Therefore, in order to verify whether the actual temperature in the pot is consistent with the displayed temperature, it is necessary to detect the temperature inside the pot body and compare the detected temperature inside the pot body with the set temperature. If the actual temperature in the pot is lower than the displayed temperature, it is possible that the cold air has not been exhausted, and it is necessary to further exhaust the cold air until the temperature in the pot is consistent with the actual temperature or the error is kept within the allowable range. However, during sterilization, the pot cover and the pot body are in a high-pressure sealed state, and the temperature probe cannot be placed in the pot from the outside. If a detection port is set, when the detection port is opened, the pressure in the pot will leak out, causing the pressure in the pot to change, affecting the sterilization effect. Therefore, it is extremely necessary to design a device that can measure and verify the actual temperature in the pot without changing the sealing state of the autoclave. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a temperature calibration device for a sterilizing pot, which can measure and calibrate the actual temperature in the pot without changing the sealing state of the sterilizing pot.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A temperature calibration device for a sterilizing pot is designed, comprising a sterilizing pot body and a sealed pot cover, the upper part of the sterilizing pot body is a sterilizing chamber; a detection hole is opened on the pot cover, a detection tube is installed in the detection hole, the bottom end of the detection tube is closed and the top end is open, and the bottom end of the detection tube extends to a position near the bottom of the sterilizing chamber; the detection tube and the detection hole are sealed, and an end cap is arranged on the top end of the detection tube;

[0007] The temperature measuring mechanism includes a temperature measuring probe, a handle connected to the temperature measuring probe, and a temperature sensing wire having one end connected to the temperature measuring probe and the other end passing through the handle and connected to the main unit of the temperature measuring instrument;

[0008] The temperature measuring probe is used to penetrate into the bottom of the detection tube to measure the temperature in the sterilizing pot.

[0009] By adopting the above technical solution, when the temperature needs to be checked during the operation of the sterilizer, the temperature probe is placed in the detection tube and penetrated to the bottom of the detection tube, and the temperature inside the sterilizer can be detected in real time. Since the bottom of the detection tube is closed, the detection tube and the pot cover are sealed, and only the end cap at the top of the detection tube needs to be opened to insert the temperature probe into the detection tube for temperature detection, and the sealing state of the sterilizer will not be changed, and the sterilization effect of the sterilizer will not be affected.

[0010] Preferably, the temperature measuring probe is vertically mounted on a guide plate, a guide groove is provided along the vertical direction of the inner wall of the detection tube, and the side of the guide plate is placed in the guide groove, driving the temperature measuring probe to move in the detection tube, so as to achieve the insertion and removal of the temperature measuring probe. By mounting the temperature measuring probe on the guide plate, and the guide plate moving in the guide groove, the stable movement of the temperature measuring probe can be ensured when the temperature measuring probe is inserted and removed, and collision and friction between the temperature measuring probe and the inner wall of the detection tube can be avoided.

[0011] Preferably, a limit stopper is provided at the bottom of the guide groove. By providing the limit stopper at the bottom of the guide groove, the guide plate is blocked by the limit stopper when it moves to the bottom of the detection tube, thereby preventing the guide plate and the bottom of the temperature measuring probe from colliding with the bottom of the detection tube.

[0012] Preferably, the number of the guide grooves is 1-4, and they are equidistantly arranged along the inner wall circumference of the detection tube. There is at least one guide groove, and one side of the guide plate moves along the guide groove to play a guiding and limiting role; when there are three guide grooves, one side of the guide plate can be placed in one of the guide grooves for movement, and guide grooves in different positions can be selected at will. When there are two or four guide grooves, they are arranged in pairs of two, and the two sides of the guide plate are respectively placed in one pair of guide grooves, so that the guide plate moves more stably under the limit of the guide grooves on both sides.

[0013] Preferably, the temperature measuring probe is installed at the center position of the guide plate, the lower end of the temperature measuring probe extends beyond the bottom end of the guide plate, and the length of the temperature measuring probe extending beyond the bottom end of the guide plate is less than the height of the limit stop.

[0014] Preferably, the width of the guide plate is smaller than the inner diameter of the detection tube.

[0015] Preferably, the guide plate is made of heat-insulating material.

[0016] The beneficial effects of the utility model are:

[0017] The utility model provides a detection tube on the pot cover of the sterilizing pot, the lower end of the detection tube is closed and the upper end is open, and the detection tube and the pot cover are sealed and connected, so that the temperature inside the sterilizing pot can be detected in a sealed state, thereby realizing the verification of the temperature inside the sterilizing pot. By installing the temperature measuring probe on a guide plate, the guide plate moves along the guide groove in the detection tube, so that the temperature measuring probe can be stably moved in the detection tube.

[0018] The utility model has a simple structure and is easy to operate. It can accurately measure the internal temperature of the sterilizer without changing the sealing state of the sterilizer, and realizes the measurement and verification of the internal temperature of a non-automatic temperature control sterilizer, so as to clearly understand the actual temperature in the sterilizer and compare it with the displayed temperature. If there is a large difference, the cold air in the sterilizer is discharged to finally reach the required sterilization temperature, thereby ensuring the sterilization effect.

[0026] The specific implementation modes of the present invention are described below in conjunction with the accompanying drawings and embodiments. However, the following embodiments are only used to illustrate the implementation modes of the present invention in detail and do not limit the scope of the present invention in any way.

[0027] Example 1: A temperature calibration device for a sterilizing pot, see Figure 1-Figure 2, including a sterilizing pot body 1 and a sealed pot cover 11, the upper part of the sterilizing pot body 1 is a sterilizing chamber 2; a detection hole is provided on the detection tube pot cover 11, a detection tube 3 is installed in the detection hole, the bottom end of the detection tube 3 is closed and the top end is open, and the bottom end of the detection tube 3 extends to a position near the bottom of the sterilizing chamber 2; the detection tube 3 and the detection hole are sealed, and an end cover 4 is provided at the top of the detection tube 3. The end cover 4 is an openable structure, and the end cover is opened when measuring temperature, and the end cover is closed when temperature measurement is not required. An exhaust hole can be provided on the end cover 4 to prevent the air in the detection tube 3 from being heated and causing the pressure in the tube to increase. The detection tube 3 and the detection hole can be connected by a sealing sleeve or other forms of sealing connectors, or can be set to a detachable connection. When the sterilizer is working, the detection tube 3 is passed through the pot cover 11 and a sealed connection is achieved through the sealing connector to facilitate internal temperature detection; when the sterilizer is finished working, the detection tube 3 can be removed to facilitate opening the pot cover and taking out the materials in the sterilizer; when no detection is needed, the detection tube 3 can be removed and the detection hole can be sealed with a sealing end.

[0028] It also includes a temperature measuring mechanism, which includes a temperature measuring probe 5, a handle 6 connected to the temperature measuring probe 5, and a temperature sensing wire 7, one end of which is connected to the temperature measuring probe 5 and the other end of which passes through the handle 6 and is connected to the thermometer host.

[0029] The detection tube temperature probe 5 is used to penetrate into the bottom of the detection tube 3 to measure the temperature in the sterilizing pot. When temperature measurement and temperature verification are required, the end cap at the top of the detection tube is opened, and the temperature probe is placed in the detection tube to measure the actual temperature inside the sterilizing pot. The measured temperature is compared with the temperature displayed by the sterilizing pot. If there is a large difference, it means that the cold air in the sterilizing pot may not be exhausted, so that the actual temperature in the pot is lower than the displayed temperature. At this time, the cold air in the sterilizing pot needs to be further discharged until the cold air is exhausted, the actual temperature in the pot is consistent with the displayed temperature, or the error between the actual temperature and the displayed temperature is kept within the allowable range. At this time, the actual temperature in the pot meets the sterilization requirements, thereby ensuring the sterilization effect.

[0030] Example 2: A temperature calibration device for a sterilizing pot, see Figure 3-Figure 6 On the basis of Example 1, the temperature measuring probe 5 of the detection tube is vertically installed on the guide plate 8, and a guide groove 9 is provided along the vertical direction of the inner wall of the detection tube 3. The side of the guide plate 8 is placed in the guide groove 9, driving the temperature measuring probe 5 to move in the detection tube 3, so as to realize the insertion and removal of the temperature measuring probe 5. When measuring the temperature, one or both sides of the guide plate are placed in the guide groove, driving the temperature measuring probe to move stably in the detection tube, which can avoid the influence of the measurement result due to the friction or collision between the temperature measuring probe and the inner wall of the detection tube.

[0031] The thermometer host is not shown in the figure. In specific applications, it is necessary to select a temperature probe of appropriate length (matching the length of the detection tube). The temperature probe and the thermometer are supporting equipment. The measured temperature can be displayed on the thermometer host. The structure and working method of the temperature probe and the thermometer host are already available in the prior art and will not be repeated here.

[0032] Furthermore, a limit stopper 10 is provided at the bottom end of the detection tube guide groove 9. The detection tube temperature probe 5 is installed at the center position of the guide plate 8, and the lower end of the temperature probe 5 exceeds the bottom end of the guide plate 8. The length of the temperature probe 5 exceeding the bottom end of the guide plate 8 is less than the height of the detection tube limit stopper 10. The width of the detection tube guide plate 8 is less than the inner diameter of the detection tube 3. The detection tube guide plate 8 is made of heat-insulating material.

[0033] The number of the detection tube guide grooves 9 can be set as required. Figure 6 The four guide grooves shown in the figure are arranged at equal distances along the circumference of the inner wall of the detection tube 3.

[0034] Unless otherwise specified, the equipment components involved in the above embodiments are all conventional equipment components.

[0035] The specific working mode of the temperature calibration device of the utility model for sterilizing pot is:

[0036] After the sterilizing pot (non-automatic temperature control type) starts working, in order to verify whether the actual temperature inside the sterilizing pot is consistent with the displayed temperature, it is necessary to detect the temperature inside the sterilizing pot. The temperature calibration device of the sterilizing pot of the utility model is used. The end cover at the top of the detection tube is opened, and the temperature measuring probe is placed inside the detection tube. The temperature detected by the thermometer host is compared with the temperature displayed by the sterilizing pot. If it is lower than the displayed temperature, it means that the cold air inside the sterilizing pot has not been completely discharged, causing the internal temperature to not reach the set temperature. At this time, the cold air in the sterilizing pot needs to be further discharged until the cold air is exhausted and the pressure and temperature in the sterilizing pot reach the set temperature to ensure the sterilization effect. During the working process, it may be necessary to detect the temperature inside the sterilizing pot multiple times until the actual temperature inside the sterilizing pot is consistent with the displayed temperature or the error is kept within the allowable range. In this way, the internal temperature calibration of the sterilizing pot is realized. When performing temperature detection, by installing the temperature measuring probe on the guide plate, the side of the guide plate moves in the guide groove, it can be avoided that the temperature measuring probe is put in and taken out and the friction or collision between the inner wall of the detection tube affects the temperature detection result. The utility model discloses a sterilizing pot has simple structure, convenient operation, can carry out temperature detection and realize temperature verification under the premise of not changing the sealing state inside the sterilizing pot, is particularly suitable for non-automatic temperature control type sterilizing pot, and solves the problem that the internal temperature of non-automatic temperature control type sterilizing pot is inconsistent with the displayed temperature due to incomplete discharge of internal cold air.

[0037] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to the above implementation modes and can be changed or modified within the knowledge scope of ordinary technicians in the field without departing from the purpose of the present invention.
